三维设计2015高考物理大一轮复习 曲线运动 万有引力与航天含近三年考点分布及考向前瞻

第四章　曲线运动　万有引力与航天 ‎(1)从近三年高考试题考点分布可以看 出，高考对本章内容的考查重点有：平抛运 动、圆周运动与牛顿运动定律的综合，万有引 力定律与实际航空、航天问题的综合(如天体 质量、密度的估算，卫星的发射、运行、变轨 问题等)。‎ ‎(2)本部分内容的考查题型较全，既有选 择题，又有计算题，对抛体运动、圆周运动、‎ 万有引力定律的应用的直接考查，一般为选择 题；平抛运动、圆周运动规律与其他知识的综 合应用，一般以计算题的形式考查。‎ ‎2015高考考向前瞻(1)运动的合成与分解、平抛运动规律、圆周运动规律、万有引力定律在航天科技方面的应用仍将是本章命题的热点。‎ ‎(2)平抛运动、圆周运动规律与牛顿运动定律、万有引力定律、功能关系、电磁学知识相结合，与生产、生活、科技背景相联系，将是2015年高考命题的趋势。‎ 第1节曲线运动__运动的合成与分解 曲线运动 ‎[想一想]‎ 如图4－1－1是一位跳水运动员从高台做“反身翻腾二周半”动作时头部的运动轨迹，最后运动员沿竖直方向以速度v入水。整个运动过程中在哪几个位置头部的速度方向与入水时v的方向相同？在哪几个位置与v的方向相反？把这些位置在图中标出来。‎ 图4－1－1‎ 提示：头部的速度方向为头部运动轨迹在各点的切线方向，如图所示，A、C两位置头部速度方向与v方向相同，B、D两位置头部速度方向与v方向相反。‎ ‎[记一记]‎ ‎1．速度方向 质点在某一点的瞬时速度的方向，沿曲线上该点的切线方向。‎ ‎2. 运动性质 做曲线运动的物体，速度的方向时刻改变，故曲线运动一定是变速运动，即必然具有加速度。‎ ‎3．曲线运动的条件 ‎(1)运动学角度：物体的加速度方向跟速度方向不在同一条直线上。‎ ‎(2)动力学角度：物体所受合外力的方向跟速度方向不在同一条直线上。‎ ‎[试一试]‎ ‎1.(2014·苏锡常镇徐连调研)在xOy平面内，一质点仅在恒力F作用下由原点O运动到A点，其轨迹及在O点、A点的速度方向如图4－1－2所示，则F的方向可能沿(　　)‎ 图4－1－2‎ A. y轴正方向　　　 　 B．y轴负方向 C. x轴正方向 D. x轴负方向 解析：选C　质点做曲线运动时，物体受到的合力方向指向曲线的凹侧，并且与速度不在同一直线上，所以C正确。‎ 运动的合成与分解 ‎[想一想]　‎ 如图4－1－3所示，红蜡块可以在竖直玻璃管内的水中匀速上升，速度为v。若在红蜡块从A点开始匀速上升的同时，玻璃管从AB位置由静止开始水平向右做匀加速直线运动，加速度大小为a。‎ 图4－1－3‎ 请思考：红蜡块实际参与了哪两个方向的运动？这两个运动的合运动轨迹是直线还是曲线？与图中哪个轨迹相对应？‎ 提示：红蜡块沿竖直方向做匀速直线运动，沿水平方向做匀加速直线运动，此两运动的合运动为曲线运动，运动轨迹为图中的曲线AQC。‎ ‎[记一记]‎ ‎1．基本概念 分运动合运动 ‎2．分解原则 根据运动的实际效果分解，也可采用正交分解。‎ ‎3．遵循的规律 位移、速度、加速度都是矢量，故它们的合成与分解都遵循平行四边形定则。‎ ‎(1)如果各分运动在同一直线上，需选取正方向，与正方向同向的量取“＋”号，与正方向反向的量取“－”号，从而将矢量运算简化为代数运算。‎ ‎(2)两分运动不在同一直线上时，按照平行四边形定则进行合成，如图4－1－4所示。‎ 图4－1－4‎ ‎(3)两个分运动垂直时的合成满足：‎ a合＝ s合＝ v合＝ ‎[试一试]‎ ‎2．某质点的运动速度在x、y方向的分量vx、vy与时间的关系如图4－1－5所示，已知x、y方向相互垂直，则4 s末该质点的速度和位移大小各是多少？‎ 图4－1－5‎ 解析：4 s末该质点在x方向上，vx＝‎3 m/s，‎ sx＝vxt＝‎‎12 m 在y方向上，vy＝‎4 m/s，a＝＝‎1 m/s2，sy＝at2＝‎‎8 m 所以v合＝＝‎5 m/s s合＝＝‎4 m。‎ 答案：‎5 m/s　‎‎4 m 考点一物体做曲线运动的条件与轨迹分析 ‎[例1]　(多选)一小球在光滑水平面上以某速度做匀速直线运动，运动途中受到与水平面平行的恒定风力作用，则小球的运动轨迹可能是(　　)‎ 图4－1－6‎ ‎[解析]　选ABC　因不知对小球的水平风力的具体方向，故轨迹有多种可能，A、B、C均有可能，因小球运动轨迹一定于小球速度方向相切，不可能出现如图D中折线，故D错误。‎ ‎[例2]　(多选)质量为m的物体，在F1、F2、F3三个共点力的作用下做匀速直线运动，保持F1、F2不变，仅将F3的方向改变90°(大小不变)后，物体可能做(　　)‎ A．加速度大小为的匀变速直线运动 B．加速度大小为的匀变速直线运动 C．加速度大小为的匀变速曲线运动 D．匀速直线运动 ‎[解析]　选BC　选物体在F1、F2、F3三个共点力作用下做匀速直线运动，必有F3与F1、F2的合力等大反向，当F3大小不变，方向改变90°时，F1、F2的合力大小仍为F3，方向与改变方向后的F3夹角为90°，故F合＝F3，加速度a＝＝，若初速度方向与F合方向共线，则物体做匀变速直线运动，若初速度方向与F合方向不共线，则物体做匀变速曲线运动，故B、C正确。‎ 曲线运动 条件 ‎ 合外力方向与轨迹的关系 ‎ ‎①物体做曲线运动的轨迹一定夹在合外力的方向与速度方向之间；‎ ‎②合外力或加速度方向一定指向轨迹的“凹”侧；‎ ‎③曲线轨迹只能平滑变化，不会出现折线。 ‎ 速率变化情况判断 ‎ 考点二合运动的轨迹与性质判断 ‎[例3]　以下说法正确的是________。‎ ‎(1)分运动与合运动的运动时间是相同的 ‎(2)合运动的速度为各分运动速度大小之和 ‎(3)两个直线运动的合运动一定为直线运动 ‎(4)两个匀速直线运动的合运动一定为直线运动 ‎(5)两个匀变速直线运动的合运动一定为匀变速直线运动 ‎(6)两个初速度为零的匀变速直线运动的合运动一定为匀变速直线运动 ‎[答案]　(1)(4)(6)‎ ‎(1)合运动类型 ‎(2)两个直线运动的合运动性质的判断 根据合加速度方向与合初速度方向判定合运动是直线运动还是曲线运动，具体分以下几种情况：‎ 两个互成角度的分运动 合运动的性质 两个匀速直线运动 匀速直线运动 一个匀速直线运动、‎ 一个匀变速直线运动 匀变速曲线运动 两个初速度为零的 匀加速直线运动 匀加速直线运动 两个初速度不为零 的匀变速直线运动 如果v合与a合共线，为匀变速直线运动 如果v合与a合不共线，为匀变速曲线运动 考点三小船过河问题分析 ‎1．小船过河问题分析思路 合运动：小船的实际运动 运动的 分解 分运动二：船相对于静水的划行运动 分运动一：船随水漂流的运动 船在静水中的划行速度v1‎ 水流的速度v2‎ 运动的 合成 船相对于岸的实际速度v ‎2．三种速度 v1(船在静水中的速度)、v2(水流速度)、v(船的实际速度)。‎ ‎3．三种过河情景分析 ‎(1)过河时间最短：船头正对河岸时，渡河时间最短，tmin＝(d为河宽)。‎ ‎(2)过河路径最短(v2v1时)：合速度不可能垂直于河岸，无法垂直渡河。确定方法如下：如图4－1－7所示，以v2矢量末端为圆心，以v1矢量的大小为半径画弧，从v2矢量的始端向圆弧作切线，则合速度沿此切线方向时航程最短。‎ 图4－1－7‎ 由图可知cos α＝，最短航程x短＝＝d。‎ ‎[例4]　一小船渡河，河宽d＝‎180 m，水流速度v1＝‎2.5 m/s。‎ ‎(1)若船在静水中的速度为v2＝‎5 m/s，求：‎ ‎①欲使船在最短的时间内渡河，船头应朝什么方向？用多长时间？位移是多少？‎ ‎②欲使船渡河的航程最短，船头应朝什么方向？用多长时间？位移是多少？‎ ‎(2)若船在静水中的速度v2＝‎1.5 m/s，要使船渡河的航程最短，船头应朝什么方向？用多长时间？位移是多少？‎ ‎[思路点拨]‎ ‎(1)欲使船在最短时间内渡河，船头应朝什么方向？此指向与v2和v1的大小关系有关吗？‎ 提示：船头朝正对岸；无关。‎ ‎(2)欲使渡河的航程最短，船的实际速度一定与河岸垂直吗？此时应如何确定船头指向？‎ 提示：不一定；结合例题前要点讲解分析。‎ ‎[解析]　将船实际的速度(合速度)分解为垂直河岸方向和平行河岸方向的两个分速度，垂直分速度影响渡河的时间，而平行分速度只影响船在平行河岸方向的位移。‎ ‎(1)若v2＝‎5 m/s。‎ ‎①欲使船在最短时间内渡河，船头应朝垂直河岸方向，当船头垂直河岸时，如图甲所示，合速度为倾斜方向，垂直分速度为v2＝‎5 m/s。‎ 甲 t＝＝＝ s＝36 s，‎ v合＝＝ m/s，‎ x＝v合t＝‎90 m。‎ ‎②欲使船渡河航程最短，合速度应沿垂直河岸方向。船头应朝图乙中的v2方向。‎ 垂直河岸过河要求v水平＝0，如图乙所示，有v2sin α＝v1，得α＝30°。‎ 所以当船头与上游河岸成60°时航程最短。‎ 乙 x＝d＝‎180 m。‎ t＝＝＝ s＝24 s。‎ ‎(2)若v2＝‎1.5 m/s。‎ 与(1)中②不同，因为船速小于水速，所以船一定向下游漂移，设合速度方向与河岸下游方向夹角为α，则航程x＝。欲使航程最短，需α最大，如图丙所示，由出发点A作出v1矢量，以v1矢量末端为圆心，v2大小为半径作圆，A点与圆周上某点的连线即为合速度方向，欲使v合与水平方向夹角最大，应使v合与圆相切，即v合⊥v2。‎ 丙 sin α＝＝，得α＝37°。‎ 所以船头应朝上游与河岸成53°方向。‎ t＝＝ s＝150 s。‎ v合＝v1cos 37°＝‎2 m/s x＝v合·t＝‎300 m。‎ ‎[答案]　(1)①船头垂直于河岸　36 s　‎90 m ‎②船头与上游河岸成60°夹角　24 s　‎‎180 m ‎(2)船头与上游河岸成53°夹角　150 s　‎‎300 m 解决小船过河问题应注意的两个问题 ‎(1)渡河时间只与船垂直于河岸方向的分速度有关，与水流速度无关。‎ ‎(2)船渡河位移最短值与v船和v水大小关系有关，v船>v水时，河宽即为最短位移，v船vB B．vAhA，由h＝gt2得：tB>tA，由v＝可以得出vA>vB，A正确。‎ 斜抛运动 ‎[记一记]‎ ‎1．概念 以一定的初速度将物体沿与水平方向成一定角度斜向抛出，物体仅在重力作用下所做的曲线运动。‎ ‎2．性质 斜抛运动是加速度恒为重力加速度g的匀变速曲线运动，轨迹是抛物线。‎ ‎3．基本规律 以斜向上抛为例说明，如图4－2－3所示。‎ 图4－2－3‎ ‎(1)水平方向：v0x＝v0cos_θ，F合x＝0。‎ ‎(2)竖直方向：v0y＝v0sin_θ，F合y＝mg。‎ 因此斜抛运动可以看做是水平方向的匀速直线运动和竖直方向的竖直上抛运动的合运动。‎ ‎[试一试]‎ ‎2．(多选)物体以速度v0抛出做斜抛运动，则(　　)‎ A．在任何相等的时间内速度的变化量是相同的 B．可以分解为水平方向的匀速直线运动和竖直方向的自由落体运动 C．射高和射程都取决于v0的大小 D．v0很大，射高和射程可能很小 解析：选AD　斜抛运动整个过程中加速度恒为g，为匀变速运动，故相等时间内速度变化量一定相同，A正确；由斜抛运动的两分运动特点知B选项错误；射高与射程不仅取决于v0的大小，还取决于抛出速度v0与水平方向的夹角大小，故C选项错误，D选项正确。‎ 考点一平抛运动规律的应用 ‎1．飞行时间 t＝ ，飞行时间取决于下落高度h，与初速度v0无关。‎ ‎2．水平射程 x＝v0t＝v0 ，即水平射程由初速度v0和下落高度h共同决定，与其他因素无关。‎ ‎3．落地速度 v＝＝，以θ表示落地时速度与x轴正方向间的夹角，有tan θ＝＝，所以落地速度也只与初速度v0和下落高度h有关。‎ 图4－2－4‎ ‎4．速度改变量 因为平抛运动的加速度为恒定的重力加速度g，所以做平抛运动的物体在任意相等时间间隔Δt内的速度改变量Δv＝gΔt相同，方向恒为竖直向下，如图4－2－4所示。‎ ‎5．两个重要推论 ‎(1)做平抛(或类平抛)运动的物体任一时刻的瞬时速度的反向延长线一定通过此时水平位移的中点，如图4－2－5甲中A点和B点所示。‎ 图4－2－5‎ ‎(2)做平抛(或类平抛)运动的物体在任一时刻任一位置处，设其速度方向与水平方向的夹角为θ，位移与水平方向的夹角为α，则tan θ＝2tan α，如图乙所示。‎ 图4－2－6‎ ‎[例1]　(2013·济南模拟)如图4－2－6所示，从某高度水平抛出一小球，经过时间t到达地面时，速度与水平方向的夹角为θ，不计空气阻力，重力加速度为g。下列说法正确的是(　　)‎ A．小球水平抛出时的初速度大小为gttan θ B．小球在t时间内的位移方向与水平方向的夹角为 C．若小球初速度增大，则平抛运动的时间变长 D．若小球初速度增大，则θ减小 ‎[思路点拨]‎ ‎(1)请分析计算小球落地时竖直方向的速度和位移。‎ ‎①竖直方向的速度：_______________________________________________________。‎ ‎②竖直方向的位移：_______________________________________________________。‎ 提示：①vy＝gt　②y＝gt2‎ ‎(2)请画出小球落地时速度和位移的分解示意图。‎ 提示：‎ ‎[解析]　选D　由tan θ＝可得小球平抛的初速度大小v0＝，A错误；由tan α＝＝＝＝tan θ可知，α≠，B错误；小球平抛的时间t＝ ‎，与小球初速度无关，C错误；由tan θ＝可知，v0越大，θ越小，D正确。‎ ‎(1)解答平抛运动问题时，一般的方法是将平抛运动沿水平和竖直两个方向分解，这样分解的优点是不用分解初速度，也不用分解加速度。‎ ‎(2)分析平抛运动时，要充分利用平抛运动中的两个矢量三角形找各量的关系。‎ ‎1．(2014·无锡市第一中学质检)水平抛出的小球，t秒末的速度方向与水平方向的夹角为θ1，t＋t0秒末速度方向与水平方向的夹角为θ2，忽略空气阻力，重力加速度为g，则小球初速度的大小为(　　)‎ A．gt0(cos θ1－cos θ2)　　　 B. C．gt0(tan θ1－tan θ2) D. 解析：选D　将t秒末和t＋t0秒末的速度分解如图所示，则tan θ1＝，tan θ2＝，又vy2＝vy1＋gt0，解得v0＝，故D正确。‎ 考点二类平抛运动问题分析 ‎[例2]　在光滑的水平面内，一质量m＝‎1 kg的质点以速度v0＝‎10 m/s沿x轴正方向运动，经过原点后受一沿y轴正方向(竖直方向)的恒力F＝15 N作用，直线OA与x轴成α＝37°，如图4－2－7所示曲线为质点的轨迹图(g取‎10 m/s2，sin 37°＝0.6，cos 37°＝0.8)，求：‎ 图4－2－7‎ ‎(1)如果质点的运动轨迹与直线OA相交于P点，质点从O点到P点所经历的时间以及P点的坐标；‎ ‎(2) 质点经过P点时的速度大小。‎ ‎[审题指导]‎ 第一步：抓关键点 关键点 获取信息 以速度v0＝‎10 m/s沿x轴正方向运动 质点经过O点后所做运动的初速度 沿y轴正方向恒力F＝15 N 沿y轴做初速度为零的匀加速直线运动 第二步：找突破口 要求质点从O点到P点的时间可分析沿＋x方向和＋y方向的分运动位移，利用tan α＝列方程即可。‎ ‎[解析]　质点在水平方向上无外力作用做匀速直线运动，竖直方向受恒力F和重力mg作用做匀加速直线运动。‎ 由牛顿第二定律得：‎ a＝＝ m/s2＝‎5 m/s2。‎ 设质点从O点到P点经历的时间为t，P点坐标为(xP，yP)，‎ 则xP＝v0t，yP＝at2‎ 又tan α＝ 联立解得：t＝3 s，xP＝‎30 m，yP＝‎22.5 m。‎ ‎(2)质点经过P点时沿y轴正方向的速度 vy＝at＝‎15 m/s 故P点的速度大小 vP＝＝‎5 m/s。‎ ‎[答案]　(1)3 s　xP＝‎30 m，yP＝‎22.5 m　(2)‎5 m/s ‎2．如图4－2－8所示，A、B两质点从同一点O分别以相同的水平速度v0沿x 轴正方向抛出，A在竖直平面内运动，落地点为P1；B沿光滑斜面运动，落地点为P2，P1和P2在同一水平面上，不计阻力，则下列说法正确的是(　　)‎ 图4－2－8‎ A．A、B的运动时间相同 B．A、B沿x轴方向的位移相同 C．A、B运动过程中的加速度大小相同 D．A、B落地时速度大小相同 解析：选D　设O点与水平面的高度差为h，由h＝gt12，＝gsin θt22可得：t1＝，t2＝，故t1x3－x2，ΔE1＝ΔE2＝ΔE3‎ C．x2－x1>x3－ x2，ΔE1<ΔE2<ΔE3‎ D．x2－x1< x3－x2，ΔE1<ΔE2<ΔE3‎ 解析：选B　 本题考查平抛运动知识，意在考查考生对平抛运动公式和机械能守恒条件的应用能力。因水平板1、2的间距等于水平板2、3的间距，则小球在水平板1、2之间运动的时间大于小球在水平板2、3之间运动的时间，因小球在水平方向做匀速运动，有x2－x1>x3－x2，又因小球在平抛运动过程中机械能守恒，则有ΔE1＝ΔE2＝ΔE3＝0，故B项正确，其他选项错误。‎ ‎5．如图4－2－17所示，小球以v0正对倾角为θ的斜面水平抛出，若小球到达斜面的位移最小，则飞行时间t为(重力加速度为g)(　　)‎ 图4－2－17‎ A．v0tan θ B. C. D. 解析：选D　如图所示，要小球到达斜面的位移最小，则要求落点与抛出点的连线与斜面垂直，所以有tan θ＝，而x＝v0t，y＝ gt2，解得t＝。‎ ‎[课时跟踪检测]‎ 一、单项选择题 ‎1.如图1所示，在水平路面上一运动员驾驶摩托车跨越壕沟，壕沟两侧的高度差为‎0.8 m，水平距离为‎8 m，则运动员跨过壕沟的初速度至少为(取g＝‎10 m/s2)(　　)‎ 图1‎ A．‎0.5 m/s　　　　　　　　 B．‎2 m/s C．‎10 m/s D．‎20 m/s 解析：选D　运动员做平抛运动的时间t＝ ＝0.4 s，‎ v＝＝ m/s＝‎20 m/s。‎ ‎2.(2014·湛江十校联考)平抛运动可以分解为水平和竖直方向的两个直线运动，在同一坐标系中作出这两个分运动的v－t图线，如图2所示。若平抛运动的时间大于2t1，下列说法中正确的是(　　)‎ 图2‎ A．图线2表示水平分运动的v－t图线 B．t1时刻的速度方向与初速度方向的夹角为30°‎ C．t1时间内的竖直位移与水平位移之比为1∶2‎ D．2t1时刻的速度方向与初速度方向的夹角为60°‎ 解析：选C　水平分运动为匀速直线运动，故A错误；t1时刻水平方向和竖直方向的分速度相等，则合速度与水平方向的夹角为45°，B错误；设水平速度为v0，则t1时间内的水平位移为x＝v0t1，竖直方向的位移y＝t1，所以＝，C正确；2t1时刻竖直方向的速度2v0，显然速度方向与水平方向的夹角不是60°，D错误。‎ ‎3.如图3所示，B为竖直圆轨道的左端点，它和圆心O的连线与竖直方向的夹角为α。一小球在圆轨道左侧的A点以速度v0平抛，恰好沿B点的切线方向进入圆轨道。已知重力加速度为g，则AB之间的水平距离为(　　)‎ 图3‎ A.

D．乒乓球在左、右两侧运动速度变化量之比为1∶2‎ 解析：选D　根据平抛运动规律，乒乓球在左、右两侧运动时间之比为1∶2，由Δv＝gΔt可得，乒乓球在左、右两侧运动速度变化量之比为1∶2，选项D正确B错误。由y＝gt2可得击球点的高度与网高度之比为9∶8，乒乓球过网时与落到桌边缘时竖直方向速度之比为1∶3，选项A、C错误。‎ ‎6．(2013·安徽高考)由消防水龙带的喷嘴喷出水的流量是‎0.28

解析：选A　将初速度正交分解，得竖直方向分速度vy＝vsin 60°＝‎24 m/s，水在竖直方向做竖直上抛运动，水柱的高度h＝＝‎28.8 m，水柱上升的时间t＝＝2.4 s，故水柱的水量V＝Qt＝1.12×10－‎2m3‎。‎ 二、多项选择题 ‎7．以速度v0水平抛出一小球后，不计空气阻力，某时刻小球的竖直分位移与水平分位移大小相等，以下判断正确的是(　　)‎ A．此时小球的竖直分速度大小大于水平分速度大小 B．此时小球速度的方向与位移的方向相同 C．此时小球速度的方向与水平方向成45度角 D．从抛出到此时，小球运动的时间为 解析：选AD　平抛运动可分解为水平方向的匀速直线运动：x＝v0t 竖直方向的自由落体运动：y＝·t 因为x＝y，所以vy＝2v0，由vy＝gt得：t＝，故B、C错误，A、D正确。‎ ‎8．如图5所示，在某次自由式滑雪比赛中，一运动员从弧形雪坡上沿水平方向飞出后，又落回到斜面雪坡上，若斜面雪坡的倾角为θ，飞出时的速度大小为v0，不计空气阻力，运动员飞出后在空中的姿势保持不变，重力加速度为g，则(　　)‎ 图5‎ A．如果v0不同，则该运动员落到雪坡时的速度方向也就不同 B．不论v0多大，该运动员落到雪坡时的速度方向都是相同的 C．运动员落到雪坡时的速度大小是 D．运动员在空中经历的时间是 解析：选BD　如果v0不同，则该运动员落到雪坡时的位置不同，但位移方向均沿斜坡，即位移方向与水平方向的夹角均为θ，由tan φ＝2tan θ得速度方向与水平方向的夹角均为φ ‎，故A错、B对；将运动员落到雪坡时的速度沿水平和竖直方向分解，求出运动员落到雪坡时的速度大小为，故C错；由几何关系得tan θ＝，解出运动员在空中经历的时间t＝，故D对。‎ ‎9．(2014·郑州模拟)如图6所示，光滑斜面固定在水平面上，顶端O有一小球，从静止释放，运动到底端B的时间为t1，若给小球不同的水平初速度，落到斜面上的A点，经过的时间为t2，落到斜面底端B点，经过的时间为t3，落到水平面上的C点，经过的时间为t4，则(　　)‎ 图6‎ A．t2>t1 B．t3>t2‎ C．t4>t3 D．t1>t4‎ 解析：选BD　由＝gsin αt12可得t1＝

A．A、B在第一次落地前能否相碰，取决于A的初速度 B．A、B在第一次落地前若不碰，此后就不会相碰 C．A、B不可能运动到最高处相碰 D．A、B一定能相碰 解析：选AD　A、B两球在第一次落地前竖直方向均做自由落体运动，若在落地时相遇，此时A球水平抛出的初速度v0＝，h＝gt2，则v0＝l，只要A的水平初速度大于v0，A、B两球就可在第一次落地前相碰，A正确；若A、B在第一次落地前不能碰撞，则落地反弹后的过程中，由于A向右的水平速度保持不变，所以当A的水平位移为l时，即在t＝时，A、‎ B一定相碰，在t＝时，A、B可能在最高点，也可能在竖直高度h中的任何位置，所以B、C错误，D正确。‎ 三、非选择题 ‎11．如图8所示的光滑斜面长为l，宽为b，倾角为θ，一物块(可看成质点)沿斜面左上方顶点P水平射入，恰好从底端Q点离开斜面，试求：‎ 图8‎ ‎(1)物块由P运动到Q所用的时间t；‎ ‎(2)物块由P点水平射入时的初速度v0；‎ ‎(3)物块离开Q点时速度的大小v。‎

解析：选B　由角速度公式ω＝，知同轴转动角速度相等，故B正确；根据角速度与线速度关系公式v＝ωr，两个质点的转动半径不相等，故线速度大小不相等，故D错误；根据向心力公式：Fn＝mω2r，两个质点的质量相同，转动半径不相同，故向心力不相等，故A错误；根据向心加速度公式an＝ω2r，两个质点转动半径不相同，故向心加速度不相等，故C错误。‎ 匀速圆周运动和非匀速圆周运动 ‎[想一想]‎ 在圆周运动中，向心力一定指向圆心吗？合外力一定指向圆心吗？‎ 提示：无论匀速圆周运动，还是非匀速圆周运动，向心力一定指向圆心，匀速圆周运动的合外力提供向心力，一定指向圆心，非匀速圆周运动的合外力不一定指向圆心。‎ ‎[记一记]‎ ‎1．匀速圆周运动 ‎(1)定义：物体沿着圆周运动，并且线速度的大小处处相等，这种运动叫做匀速圆周运动。‎

D．当路面结冰时，与未结冰时相比，v0的值变小 ‎[解析]　汽车以速率v0转弯，需要指向内侧的向心力，汽车恰好没有向公路内外两侧滑动的趋势，说明此处公路内侧较低外侧较高，选项A正确。车速只要低于v0，车辆便有向内侧滑动的趋势，但不一定向内侧滑动，选项B错误。车速虽然高于v0‎ ‎，由于车轮与地面有摩擦力，但只要不超出某一最高限度，车辆便不会向外侧滑动，选项C正确。根据题述，汽车以速率v0转弯，需要指向内侧的向心力，汽车恰好没有向公路内外两侧滑动的趋势，没有受到摩擦力，所以当路面结冰时，与未结冰时相比，转弯时v0的值不变，选项D错误。‎ ‎[答案]　AC ‎[点悟]‎

分析计算圆周运动问题时，常会遇到由重力和弹力(可以是支持力，也可以是绳子的拉力)的合力提供向心力，而在水平面上做匀速圆周运动的一类问题——圆锥摆运动。因此，掌握圆锥摆运动特征可以快速解决这一类圆周运动问题。‎ 下面为两个常用的圆锥摆运动规律：‎ ‎1．圆锥摆的向心加速度a＝gtan α 设摆球质量为m，摆线长为L，摆线与竖直方向夹角为α，由图可知，F合＝mgtan α 又F合＝ma向，‎ 故a向＝gtan α 可见摆球的向心加速度完全由α决定，与摆线长无关，即与运动的半径无关。‎ 图4－3－12‎ ‎2．圆锥摆的周期T＝2π 由F合＝m·Lsin α和F合＝mgtan α可推理得圆锥摆的周期T＝2π 设摆球圆周运动的平面到悬点的距离为h，则h＝Lcos α，‎ 故T＝2π 由此可见，圆锥摆的周期完全由悬点到运动平面的距离决定，与小球的质量、摆线长度无关。‎

‎[解析]　根据上述规律可知，此题中的A、B 两小球实际上是具有相同的向心加速度，根据a＝＝Rω2＝可知，加速度相同时，半径越大，线速度越大，角速度越小，周期越大，即由RA>RB，可知vA>vB，ωA<ωB，TA>TB，则选项A正确，B、C错误。由于A、B质量相同，在相同的倾斜面上，则向心力相等，进一步可知两球所受的弹力相等，故可知选项D错误。‎ ‎[答案]　A ‎[题后悟道]　比较两个圆周运动的各物理量之间关系时，实际上就是找出两个圆周运动之间存在的隐含的相同因素，然后用控制变量法即可判断各物理量的关系。而上述两类特殊规律正是反映了不同圆周运动之间的相同因素，是分析圆周运动问题经常遇到的类型，希望同学们能够掌握。若例题中两小球质量不相等，则上述运动量仍然符合规律，只是弹力和向心力发生变化而已，这是在分析问题时要注意的一个细节问题。‎

The pursuit will be disappointed; to be alive, you will have trouble. Life is the most afraid of what all want to care about, but also what all grasp is not firm, without scenery, separated populations, such as not to desire, all docked in the fate of the end. Why is too rigid, the natural, to go stay not to live, let go of obsession, revel is 20, if the fate of the broken Hopes of sailing, please don't despair, the coast is still, if the fate of the withered petals of the beautiful, please do not sink, the spring is still,‎ ‎ life will always be endless trouble, please don't helpless, because they are still alive, is still a dream, the sun still, we still.

The complex world like a Significance of pride. Hope is the ornate palace, outside people admiring the magnificent, living in the deep knowledge of living it to pay the price. Simple world as a simple log cabin outside ridiculed shabby, the heart is willing to go live to know the joy. Suffering and joy is their own choice. 22, learn how to use a single powerful heart, let the past be the past, let the future come. Life is really the end of the end of an eagle is flying wings, life is constantly pursuit. Don't miss to regret, don't wait for old just miss. Time to return, seize every moment, again painstakingly again tired also Those struggling to fly. 23, life could not Yimapingchuan, even flat pavement, inevitably there will be a few pieces of roadblocks.

Below I talk about their own situation, please put forward valuable opinion. Main understanding (a) serious discipline, to create a delicate gas is in the general environment in ‎ accordance with the Central Commission for discipline inspection organs, < of Organization Department of CPC Central Committee on strengthening the election of the notice of customs supervision >, municipal < on doing a good job City Township leadership transition in the notification > and county Party Committee Organization Department of the county Party Committee Organization Department < on the convening of the correct treatment leave turn ensure transition Fengqing gas is a feature of democratic life notice > files related to the spirit of the requirements, earnestly implement the "nine is prohibited, nine shall be" the solemn discipline, I earnestly study the < Chinese Communist Party principle of honesty and self-discipline >. < Chinese Communist Party Disciplinary Regulations >, < promote leading cadre of some regulations >, < party and government leading cadres selection and appointment Regulations > and file, and a profound understanding of the nine is prohibited, a nine law "discipline essence and firmly safeguard the election of serious Ensure the unhealthy tendencies have successfully completed, and actively create a delicate gas is the election of environment, to ensure that the election, so as ‎ to further strengthen the town leadership and cadre team construction. Through the study, in-depth thinking, to a serious discipline the importance and necessity of a more profound understanding. First, it is the iron discipline. The central put forward the "nine is prohibited, nine shall be the reason for early serious general discipline, designated" high-voltage wire, "itself reflects the party committees at all levels of the reelection of attaches great importance to the objective is bright resolute attitude, the implementation of effective measures, the same candidate to fight with discipline election of wind Discipline in gas is health. Secondly, this is prevenient. From some typical cases, we can see that individual cadres election to engage in speculative hack canvassing votes, in violation of discipline, and ultimately paid a high price. The destruction of Hengyang election case and Nanchong canvassing bribery case that strengthen election discipline, serious election discipline of necessity and importance. The discipline of publicity to the public, wide report, that is, early warning, early hit precautionary needle, tell the cadres should do what shouldn't do, what to do and what not to do, and better education of cadres, warning ‎ cadres, and build a strong line of defense, to avoid the occurrence of similar problems. There is duty. Serious discipline, with a strong team is an important starting point. As the leadership of the party members and cadres, take the lead in the implementation and take the lead in upholding the election of discipline, which is a major political responsibility. Must be clear requirements, strict constraints themselves, cherish the honor, safeguard the image of the organization; promote righteousness, play an exemplary role. Especially as deputy Township, but also to give a full play to its role, always stand in the discipline of first-line maintenance. The wind Su Ji through the election of the work of the whole process. (II) serious discipline, treat correctly leave turn as a cadre of the party, whether it is in, is back, stay, turn are organization Metabolism of entrepreneurial career, need and development need. So, his first with a broad mind to treat "leave turn". The position is officer positions, power for the people service tools. Different positions of the party's cause, plays a decisive role, the same important. To ability strong, style of comrade to important positions ‎ and applause, is full of vigor and vitality and promising young cadres in leadership and cheer for their own "leave turn" and calmly face, calm place. Second is to a healthy state of mind to treat "leave turn". The personnel of metabolic, between the past and the present. Cadre new old alternant, team, push In the party constitution control strict working to career development objective need, is never the end of the historical process. Each a cadre must face up to the laws of nature to think we also took the former relay baton "go on leadership post, regardless of the current positions, positions and responsibilities have what change, can do for peace of mind and mood, such as water, in a happy mood. (3) carefully and find out the problem, correct understanding of themselves, even though they do conscientious, serious attitude, honesty in politics, but high standard < >, the control standard, especially control learning, striving for excellent activities emerge in large numbers of advanced characters, advanced deeds Static not consciously practice the "strict three real" and strengthen the party spirit accomplishment to find the gap, swing is insufficient, a clear direction, mainly manifested in the following aspects: one is the ‎ learning initiative and self-consciousness. Often busy with work as an excuse, not consciously take the initiative to spare time to learn. Is often superior to learn what to learn what, and work closely to learn, and working relationship is not less to learn. Mainly manifested in the theoretical study is not thorough, system is not thorough, the Marxism Leninism, Mao Zedong thought, Deng Xiaoping Theory and "Three Represents" important thought, the scientific concept of development and learning, general secretary of the series of speech learning, just from the surface on learning In the less less less and not deep enough, not from the deeper study, to study, to understand, to sentiment, to use, to guide the work.

The inspection was carried out research activities, there are surface examination, thematic research, listen to reports and discussion research, the general requirements and specific guidance, in a certain extent, affected the timely discovery and solve. Third is the level of leadership,‎ ‎ leadership and need to be further improved. Stroke the personnel selection is positive, work coordination and cooperation can't to the best effect; in the coordination to deal with some complex problems, the approach is not enough. Especially encountered, time is tight, the task is heavy, is often the soldiers to be blocked, the water to soil cover, struggling to cope with. The global and forward-looking innovation is not enough. (4) to ensure that the transition delicate gas selected loyal to the party loyal to the people of leading cadres (recommended) for the county to provide accurate information to ensure the transition in the air, after the general election of work have a greater change. The second is balanced, promote the work in an orderly manner. In the future a period of time, the transition will be in the county under the leadership of the Extended surface.

To build a well-off society in an all-round way by 2020 is the party's eighteen to the whole Party and the people throughout the country to make a solemn commitment. Lead the city people out of ‎ poverty to become rich go straight towards well-off, Party committees at all levels, political responsibility and mission of the times of the government's major political, technology sector is also the bounden responsibility. Municipal three tenth plenary session made < on the go all out win battle poverty alleviation and development to ensure synchronous completion of a comprehensive well-off society decided >, proposed to further promote the "five a group of" precise action to help the poor, "six precision" and "1 + 6" poverty alleviation projects, clear the "add Great science and technology achievement transformation efforts, accelerate the construction science and technology poverty demonstration village and demonstration households, give full play to the role of modern information network, for the impoverished village poor households to provide production technology, market information, policy advice, encourage scientific and technical personnel to the poor village launched a to one helping and guiding the development of income industrial projects, strengthen technical training and propaganda of popular science, highlighting grasp large breeding, family farmers, agricultural co-operatives are the backbone of the training ‎ "technical poverty alleviation mission. The city's science and technology sector must be from the political height, the assault fortified positions that help deficient up as the most important task, the most urgent work. The most arduous mission, to science and technology for precise poverty alleviation promote to speed up a well-off society in an all-round way Decision to deploy, boost the process to precise technology to poverty alleviation and the effectiveness of a well off society in an all round way. One should obey the overall situation. The city's scientific and technological system of cadres and workers, especially leading cadres, should have the political consciousness, ideological conscious action conscious, in accordance with the central, provincial and municipal deployment requirements, to strengthen the organization and leadership, reasonable arrangement of time, carefully study the deployment, to ensure poverty. There must be resolutely implement the political position and character, poverty alleviation and the attitude to be distinctive, poverty alleviation action should be strong, to politics, to understand the overall situation, re implementation, see results.

Prominent precise poverty technical training, poor village informatization construction, technology oriented poverty reduction model village and ‎ demonstration households construction precision technology poverty alleviation focus, in a precise sense, precise attitude, precise style, go all out to fight the precise technology of poverty alleviation and battle.‎ Three, it is necessary to strengthen science and technology funds supervision as an important means to enhance the quality of the project. Science and technology project fund supervision is the key to the implementation of the project of science and technology. In recent years, especially during the "Twelfth Five Year Plan" period, the system of science and technology management in the city vigorously to declare the implementation of the country and province science and technology projects, science and technology demonstration lead brought obvious effect and improve the scientific and technological innovation capability of enterprises, boosting the characteristics and advantages of industrial development, science and technology support to the economic and social leading role improved significantly. In the project management of science and technology, in addition to seriously implement the state, provincial science and technology project ‎ management rules and regulations, and the actual Bazhong, established the access system of science and technology projects, the project of science and technology commissioner system, science and technology Project credit system and scientific and technological projects honest commitment system, and the Municipal Finance Bureau jointly issued the > < Bazhong City Science and technology development funds management approach, formulated the "trilogy of seven" science and technology project implementation specification, these are worth fully affirmed. However, we should also see clearly, we in the science and technology project management still exist "account of the special accounts, earmarking system is no effective implementation and other issues. In particular, this year the Audit Commission Chengdu Tepai ban on Bazhong confidence found in the audit of science and technology business incubatorProblem has certain representativeness. The audit to us sounded the alarm, should cause everyone vigilance. Here, I will strengthen science and technology project budget supervision put forward four requirements: a strict project reporting, prevent fraud. Implementation of the project to declare the competition mechanism, the ‎ annual financial support to science and technology projects oriented society Bulletin, conditions open content, open competition to declare, open field investigation, public presentations, the public assessment of the decision, do full open and transparent, fair, accept social supervision. To those who resort to deceit or something real is not clear, suspected of defrauding, impersonator national subsidy funds, once found immediately cancel Declaration of qualification, recovery of funds subsidy and discipline in accordance with the law strictly held responsible. Second, we must innovation funds supervision. In county finance to establish science and technology project "account", the project undertaking entity in accordance with the key nodes task completion by formal invoice to apply for funding and audited by the Department of science and technology, the Ministry of finance funds, and resolutely put an end to project funds are retained, misuse and misappropriation. Third, we need to strengthen scientific and technological project supervision. Department in charge of science and technology to strengthen project inspections to check or checks, of ineffective implementation to strengthen the supervision and the existence of violations of ‎ responsibility into the project undertaker rectification. To establish a scientific and technological project, "black list" system, the Project implementation quality particularly poor recorded in the "black list", stage or permanent abolition of the applicant country, province, city science and technology project qualification. Fourth, it is necessary to carry out training funds management. Science City Bureau to the initiative to meet with the finance department, organize project unit commitment held science and technology project funds management training, of country, provincial and municipal science and technology project funds management of the relevant policies, financial acceptance specification, mid supervision points, budget review points and key contents were training system, to ensure the use of project funds safe and reasonable.‎ Thank you all!‎ To implement the central, provincial, city and county to make important decision about the grass-roots party construction work in the deployment, push forward the county public security organs in the work of Party building,‎ ‎ further strengthen the party secretary of the governing party and party liability, according to < of the Organization Department of CPC Committee of Xuchang County on the issuance of the "counties as well as the authority of Party building debriefing appraisal implementation solutions" notice > requirements, according to the arrangement of the Bureau of the party work. Today, the organization held the county public security organs party secretary grasping grass-roots party construction work in the debriefing will. The implementation of this is a powerful measure to the Secretary of the party organization construction of the party,, and is learning to carry out the party's spirit of the Fifth Plenary Session of the eighth session of the, grasp the new situation of Party building work under the rules, pushing Public security party building services in the public security center of the inevitable requirement.‎ Just now, the 3 Juzhu unit Party branch secretary of debriefing, below I on the 3 party organization work one by one review.‎ Party branch of the Political Department Good: first, strengthen ideological and political work, pay close attention to the work of the implementation. The Political Department of the Party branch strictly in accordance with the requirements of bureau Party committee, to "strict three real special education as the main line, take effective measures, pay close attention to the ideological and political work of the implementation, strengthen the education of Party members and the police thought, improve the Police Ideological and political consciousness, make a solid foundation for public security work smooth development of health. Second, strict management team, boost the morale of the team. Strict implementation of Police Ideological Trend of periodic analysis, timely grasp the ideological situation of the personnel; strictly implement the system of check on work attendance, strengthen the daily management; cash rewards and punishments, continue to boost the morale of the team. The third is The intensification of police training, improve the police actual combat skill. Seriously and actively carry out a series of training activities and <‎ ‎ Henan public security network, > learning activities, the majority of police in the political quality, physical quality, professional quality, policing skills improved. The fourth is to adhere to the preferential treatment from the police, the warm pool police. According to thRequirements, and actively do a good job of personnel management work, to run within the scope of the policy, help the police solve the practical difficulties, the police systemic heart into work. The fifth is strengthening propaganda, promote righteousness. Around the center of the public security work, actively do a good job in the publicity, fully display the spirit of good public security team. Six is to fulfill the responsibility of Party building, do a good job of education and management of Party member team. Sound and perfect "three class", Party of democratic appraisal, commendation and reward system, effectively enhance the branch of the creativity, cohesion and fighting capacity.‎ Shortcomings: is ideological and political work still can not adapt to the new situation, new task, in the form of a single, innovation is not enough, lack of learning ‎ education of the appeal and study the effect of education needs to be improved, the political department to strengthen the guidance to the grass-roots units. The second is the branch of organizational life will implement the is not good enough to play an exemplary role.‎ Traffic Police Brigade Party branch System of good practice: one is grasping the implementation of the work of Party building system, enhanced branch team cohesion, combat force. The brigade Party branch always pay close attention to the work of Party building and would not let go, conscientiously perform their duties, strict implementation of democratic life etc., to develop the branch of learning plan, all equipped with learning record the experience and experience the and organize regular inspection learning, ensures that the learning plan, implement, effect. Second is to carry out the "strict three real special education. The development of special education learning scheme, held a party branch focus on learning and the level of consultation forum, deputy director in charge of, brigade ‎ leader for the party members and the police on the lectures, deployed to carry out Ban Zicheng throughout the Yan Zhenchang Yang Shuicai to relive the oath to join the party, visit the memorial hall, learning advanced characters, micro lectures attention and learning characteristics of the activities, and to develop measures for rectification. Three is to pay attention to the party building work into the public security work. The brigade Party branch and always will be the work of Party building in 9.3 security, national civilized city re examination, the SCO security meeting, the focus of illegal investigation, "sword", "anti terrorist violence, to ensure safety", "five wave", "camp turn non bus", "detoxification", the focus of the work, in a timely manner to carry out the pre war mobilization, wartime dynamically judged, the post-war award in recognition of a series of measures Members always fighting in the first line of traffic management, all traffic police has always maintained a high state of mind, a strong impetus to the work carried out.‎ Shortcomings: first, there is a "hand hard and soft" phenomenon. Of work of Party building under the new ‎ situation is not enough emphasis, focus on light business building, re form light effects. The second is measures are not enough effective. In particular, catch a party to build working innovation consciousness is not strong, measures and methods used in the experience of the old, old practices and effectiveness needs to be further strengthened. The third is three lesson "not very good insist, life of the party organization to carry out less often.‎ Zhao police station Party branch Good practice: one is to strengthen the study and education. To "strict three real special education as an opportunity to take leadership lectures, seminars, individual learning, exchange of experience in various forms, the police organization learning leaders at all levels of the spirit of the important speech, < > in the constitution as well as the side of corruption cases and asked party members and the police carefully recorded study notes, writing experiences, join and pay attention to the micro lectures, according to the control requirements of ‎ inspection, enhance their own, to ensure that the learning effect. The second is to strengthen the leadership responsibility. Party branch secretary as the first responsibility of honest government, earnestly implement the" four person ", and insisted on the" important work personally Department Department, major issues personally intervene, personally key aspects of coordination, supervision of important cases personally ", Party branch members always strict demands on themselves, play an exemplary role model. Third, strengthen the service for the people. Every act of the masses for the warm reception, carefully recorded masses anti reflect each a problem, and make the resistancee bureau Party committeeHeart to answer, and constantly improve the quality of service. Combined with the "one village, one police work, police organization carefully touch row all may affect the stability of the unstable factors, resolve conflicts and disputes, and arrange for the police with daily visits, issued security leaflets, collecting sites, personnel information, promote the harmony police.‎ Existing problems: a party branch team party affairs ‎ knowledge is not rich enough, on some of the procedural provisions are not familiar with, in a certain extent restricted the work carried out. The second is regular ideological education is not deep enough, the ideological trends of the police command is not timely and accurate. Third, there is a need to improve the management level of refinement, police standardization awareness is not strong enough, daily habit is not quite self-conscious.‎ Since this year, bureau unit Party branch to "strict three real special education as the main line, to the service center, troop construction as the focus, adhere to the combination of ideological building of the party and the system of the party, solid to carry out the comprehensive strictly required, to further standardize the construction of the party organization, continuously improving the quality of Party members and police, continue to strengthen the party building innovation, service building execution significantly improved, has made remarkable achievements.‎ Meeting debriefing of 3 units in the work of Party ‎ building problems in other units are also different degrees of existence to other units by the party building debriefing, draw on the experience of face the problem, replicability, careful analysis of rectification, promote the sustained and healthy development of the work of Party building units.‎ Below, to further strengthen the county public security organs party building work stressed the views of five points.‎ One, improve the ideological understanding, enhance the sense of political responsibility and historical mission Follow the basic construction of the party's eighteen years, Xi Jinping, general secretary: the series of important speech to the party put forward many new ideas, new judgment, the new requirements is to promote grass-roots party building work. We should thoroughly study and understand, and consciously assume responsibility. One is to grasp the party building "three questions" of the new requirements. Xi, general secretary of the party's mass ‎ line education practice summary of the General Assembly on the proposed the construction of "three questions, namely:" is not the party committees at all levels and the departments of Party committees (party) to achieve the sedulous catch a party to build is not at all levels of Party committee secretary, the Department of the party committees (party) secretary become strictly administering the party secretary? Is not at all levels and all departments of the party Forced the construction of Party committees (party) members to fulfill the responsibilities strictly responsibility? "General Secretary of the party building" three questions ", directed at the crucial point, enlightening, three mirror placed in front of everyone, let you according to a photo, see a look, want to think about the conscious of it, is the three pieces of papers placed in front of us, it is clear to judge ourselves whether in to do their duty. Building" three questions ", urge people to watch, thought-provoking, and convey a strong responsibility to ask signal. The second is to understand the building" three no "new judgment. Xi, general secretary of the party's mass line education practice summary congress pointed out that" history and reality Are ‎ accounted for in the police forces of discipline, do not do, is to stop the event tells us, not a clear responsibility to implement the responsibility, accountability, and strictly administering the party is not to ". General Secretary of the" three no ", a clear responsibility to implement the responsibility, accountability, and point out the key. The county public security organs is a team of the Communist Party as the main body, Party members and the vast majority of bureau of belonging to different units of the leadership cadres and backbone of the party members, the power and responsibility are relatively concentrated in the party's construction, must be clear responsibilities, the implementation of responsibility, accountability, or catch a party to build is an empty word. Three is to clear the" three grasping "new initiatives. The total learning book Remember that catch a party to build must grasp the responsibility system, grasping accountability must grab the responsibility person, grasping the responsibility must catch the first responsible person. Why should we let the Bureau unit Party branch secretary of the debriefing is to implement general secretary put forward "3 catch". To seize the party organization's primary responsibility, seize the ‎ key issue.‎ Two, the full implementation of the task of ideological construction, the theory of armed tasks implementedGeneral Secretary Xi Jinping in the mass line of educational practice summary congress put forward in the new period party building thought of tasks and requirements, to strengthen the construction of the Party pointed out the direction and path. One is to strengthen theoretical study. The urgent task is to fully understand the study and implement the spirit of the fifth plenary session of the eighth session of the significance of, the organization of Party members and the police through the focus on learning, self-study and special counseling and other forms of serious in-depth learning, adhere to the first step in learning, deep layer, accurately grasp the spirit of the Third Plenary Session of the Eleventh Central Committee, and do the thinking and learning gains, use it. The second is to strengthen the party spirit temperance. Adhere to the school party constitution. Through the center of the group learning. Secretary of the party organization about lectures and other forms of learning the party constitution,‎ ‎ enlightenment spirit, guide Bureau unit Party branch and all members of the police to firmly establish the consciousness of the party. Persist in learning advanced. Vigorously carry forward the spirit of Jiao Yulu, Yang Shuicai spirit, seriously study the advanced deeds of Comrade Yan Zhenchang, deep fine shine Dusing the police party guided, to strengthen public opinion and public servant consciousness, consciously practice the "strict three real. The third is to strengthen the party and Party discipline education. For the ideological construction of the party faces new tasks, new requirements, the emergence of many new problems, new situations, and actively take the initiative to adapt to the constantly emancipate the mind, innovative ways, making use of the Internet, micro channel, micro Bo new platform for new, enrich the content of education, improve education forms, the constant reminder education, enhance the police Party discipline in awe, guide Party members and the police do political understanding discipline about the rules of the leaders. The fourth is to strengthen the ideological and moral education. Guide the party police exemplary practice the socialist core values, cultivate good political and moral ‎ character, professional ethics, family virtue and morality, forming a strong atmosphere of moral construction. Pay attention to strengthen the positive guidance to the police party ideology, adhere to the diversification of the social ideology guided by the system of theories of socialism with Chinese characteristics, improving and perfecting the Party members and the police thought The dynamic analysis of mechanism, providing an ideological guarantee for the purity and firmness of team members.‎ Three, fully implement the strict requirements, the management and administration of the party's responsibility to implement General Secretary Xi Jinping stressed that to implement strictly the responsibility, do a good job of Party building as the biggest achievement. Therefore, in my bureau implement comprehensive strictly required must be the party tube responsible party implemented. First, to further implement the responsibility system in Party building. To establish and improve the party building responsibility assessment mechanism, at the beginning of ‎ the year to progressively signing party builds working target responsibility book. Party organizations at all levels is mainly responsible for comrades to do a good job of Party building as the greatest achievements, adhere to the development wholeheartedly for, to concentrate its attention on the construction of the party, the party building work is included in the agenda, and business to work with the deployment, with checks, with the implementation of, true to form Party grasping, Secretary to take the lead in efforts, in charge of the leadership Specific catch, catch a, layers of implementation pattern of Party building work. Is to improve the reporting and appraising system. In accordance with the "debriefing the party building, the appraisal rating of Party building, Party building assessment test, use of cadres at request of the party", CF county Party debriefing practice, and constantly improve the annual party built debriefing appraisal system, in particular, to the year debriefing appraisal evaluation and annual comprehensive examination closely together, the party builds the job evaluation results into the leading bodies and leading cadres of the annual comprehensive assessment system, strengthen the use ‎ of dynamic management and results of debriefing appraisal work, further enhance the debriefing appraisal of scientific, effective and directive The new integration business. Three is to improve the "three class" system. "Three class" system is to improve the party's organizational life, strict party member education management system, we must do a good job in the implementation and long-term persistence. According to "the party secretary of the organization lectures", "party members and cadres micro lectures and Thematic Party Day activities, innovation" three class "form, rich" three class "content, pay attention to the work of Party building with the public security work, the formation of" the same resonance frequency, the linkage of communion "party organization life situation. At the same time, the" three class "system implementation of join or be admitted to the party organization committee debriefing appraisal of important content, strict grasp the" three class "system Real.‎ Four, strict political discipline and political rules.‎ Guide all Party members and the police in ideological ‎ political action always as the general secretary of the CPC Central Committee with Comrade Xi Jinping highly consistent, involved in major political principle, political stand, political views and other issues, we must be sober, stand firm. Guide the members of the civilian police to strengthen the sense of organization, determined to do the individual is subordinate to the organization, the minority is subordinate to the majority, the lower level to the higher level, and the whole party to the Central Committee. Some time ago, I held a party enlarged meeting, focus on adherence to the party's political discipline and political rules of thematic theory study, I at the meeting for the feelings to speak. I understand, party a concept of organization, can not see Party, touch not. According to the materialistic point of view, the material determines consciousness, existence determines consciousness, consciousness is the objective things in the brain to reflect, then, how to prove that the party's existence? Like the current, can not, can not be touched, but through the wire carrier, connect power supply, the electric light, the motor is running, it is proved that the current existence. Similarly, the party is by living every Party ‎ member, every Party member, speech and action of the carrier, reflecting party. Party is a whole, in order to normal operation, each party members according to their personality characteristics. Academic knowledge, professional knowledge, hobbies, physical condition, age, work experience, work experience and other comprehensive evaluation, main task of the division of labor and in jointly do a good job in party work, is mainly responsible for the Division I business, then in my division of work, in the Party committee collective discussion by, decision, foreign, on every level of members can to bureau of the party in the name and identity delivered a speech, the organization of work. In specific work, in the higher Party committees have clear provisions of the spirit, in accordance with the spirit of the documents of ranking Party committee, combined with my work of the division of labor, on behalf of the bureau Party committee put forward their views and suggestions. Since Party members according to the higher Party committees to the spirit of the document can be Bureau on behalf of the party organization of work, then the behavior has party authority and seriousness, we should respect them and be with, give ‎ support, cannot according to personal preferences, personal understanding and awareness, regardless of the occasion, in broad daylight, in meetings, especially in the lower front of, guilty of liberalism, published the higher Party committees have been expressly prohibited speech, also cannot euphemistically called the personal point of view; regardless of party image and personal image, irresponsible, gossip, just open the river, grumble, grumble about; even, sarcastic ridicule, sarcasm, oblique accusations, make people Hold the most stringent start speech, personal attacks, vent personal grudge; more even, with ulterior motives, ulterior motives; fan Yin breeze, will-o '- the wisp, deliberately and party dissension and discord, rumors spread, the spread of division, and the party and the people, the hearts of the people, the decline of morale. This kind of behavior is the party's discipline are not allowed, from my start, from the members of the Party committee member, once, who despite the party discipline, drunk, behind, the key moment, in violation of the party's political discipline, political rules and wait for the party discipline. We must strictly comply with the implementation of the central and superior party committee ‎ has clearly defined, does not allow bargaining, unconditional obedience, unconditional , does not allow a discount, or disguised discount. In addition. We want to strictly enforce the system of democratic life of the party, Party of democratic life, it is necessary to carry out criticism and self-criticism, is between the members of the Party committee of the mutual criticism, remind each other, will not do not speak, gossiping afterwards. Guide Party members and the police strictly request reporting system, regularly party members to execute the political discipline of political rules situation analysis judged and thematic summary, constantly enhance political of the political life of the party, the principle and militancy.‎ Five, comprehensively improve the scientific level of Party building, the task of the party building To enhance the scientific level of the construction of the party is our party according to the worldly affairs, national and the new changes and new challenges of the party put forward the major issue is effective to deal with the four test ", resolve the pressing requirement of" four ‎ big risk "is the only way to maintain and develop the party's advanced natuStep is to strengthen the party's cohesion, attraction and the fighting power of the inevitable choice. Under the new situation, it is necessary to apply the law of the ruling party construction of Marxism, according to the basic requirements of maintaining the party's advanced nature, continue to study new situations, solve new problems, sum up new experience, make the party building in scientific orbit continues to advance. One to focus, efforts to lay a solid foundation. Continue to carry out the "two hit" activities, accurately grasp strictly required new rules and characteristics of the work of Party building under, deepening grass-roots increase of basic party organization and Party member quality upgrade plan. Continue to carry out the window units vanguard party post, window model building activities, and continuously Enhance the party members and the police involved in activities to create enthusiasm. Increase of Party organizations and Party members advanced typical advocacy training efforts to become a "sign", "evergreen tree". To broaden the party serving the masses channels, construction of Party members contacting and serving the masses work ‎ system, make the Party member to become truly keep in mind the purpose, advanced elements of the heart of the masses. Establish and improve incentives within the party, care, helping mechanism, we do care and love grassroots cadres, old party members, difficult life member. In order to promote the party construction services, continue to carry out "party members and counterpart assistance" live and on-the-job Party member volunteer service activities. Second, we must strengthen management, efforts to enhance the party members Quality, and conscientiously implement < the Communist Party of China the development of Party Work Rules >, adhere to strict standards, rigorous training, strict procedures, strict regulation and control, and continuously improve the quality of Party members, optimize the structure of Party member team. Strengthening of different kinds of police, the classified management of Party members in different positions, through the implementation of target management of Party members, record management, star rating etc. ways to strengthen the education of Party members, management and service work. Adhere to the mass appraisal, solid and effective to carry out members of the public commitment, no post party post ‎ duty activities, give full play to the role of Party members. Actively introduce the Internet +, by means of information to strengthen the education and management of the party members and make full use of "Xuchang male Ann party building network "," peace of Xuchang, Communist Party members, Liancheng micro lectures and other network platform to strengthen the education and training of Party members. Three to strict requirements, efforts to improve the party's style of work. To build a first-class units, to create a first-class team, cultivate first-class style, create first-class performance as the goal, combined with learning from the advanced models, and effectively solve the police party in the party spirit, moral character, style and ability existing prominent problems; adhere to the lead austerity, oppose extravagance and waste, and oppose formalism, bureaucratism and seriously practice the "strict three real, establish a good style of work; earnestly implement the" eight insist, eight against ", advocate diligence Excited to learn and apply what they have learned, the heart of the masses, serve the people, grab get right on the job really, and to ensure the effectiveness of, hard work, thrift, the overall situation,‎ ‎ curried, develop democracy, solidarity work, impartially and with the right of honesty in politics, life is decent, healthy interest in eight aspects of good atmosphere, promote the county public security organs party political construction has made new achievements. Fourth, it is necessary to produce battle fort effect. Party organizations at all levels to grasp the practical to the center of the public security work service key links, adhere to the completion of difficult and perilous task as the main battlefield of the work of Party building, the more encountered serious incidents, major rescue mission, a major security tasks, the more you want to play the party organization The role of core, and earnestly do a good job before the war mobilization, wartime motivation, war veteran and so, truly party members and cadres to fight to where, the life of the party organization will extend to where, the role of fighting bastion of the party organizations play where, reflecting the party building work to promote and protect the power.‎ Comrades, in the circumstances to promote comprehensive strictly new situation, the Party Central Committee and the ‎ Party committee of a higher level of the construction of the party proposed the new, higher requirements, the work of Party building task is arduous, the glorious mission, rare opportunity. Let us to the debriefing meeting as a starting point, in the Bureau of the party's correct leadership, conscientiously study and implement the series of important speech of General Secretary Xi Jinping, spirit and the party's spirit of the Fifth Plenary Session of the eighth, thoroughly implement the comprehensive strictly required, continue to carry forward the party's fine tradition, hearten spirit, do solid work, the enterprising spirit, selfless dedication, to continue to create the county public security organs of Party building work in the new situation, to maintain social stability to ensure Successful completion of the task,re, also is aPromote public security undertakings flourish, for the construction of a beautiful and happy Xuchang county to make new and greater contributions!‎ Carry out the party building debriefing appraisal work, implement the central and provincial Party committee, the municipal Party committee and comprehensively promote the ‎ strictly deployment requirements, implement strictly the responsibility, tamp the foundation of Party Construction of major initiatives. Public security organs as the party's absolute under the leadership of the democratic dictatorship force, as the party and the people in the hands of the "hilt" must to strengthen the work of Party building and walk in the forefront, and make an example. From just four of the Secretary of the party organization debriefing situation, the party organization of debriefing of Party building and ideological work attaches great importance to prepare more fully, in the debriefing process, say achievements do not exaggerate, speak the problem does not cover, emphasize not vanity about rectification, truly realistic.

This is not only a debriefing meeting and Party building the responsibility to implement, today the debriefing, to do a good job of new period party building work will play a very good role in promoting. Next, according to the city bureau Party Committee on Party ‎ building work on the arrangements, Bai chief commissioned by combining city Bureau of Party building work of new requirements, borrow this opportunity to revisit four points. To improve the ideological understanding, enhance the sense of responsibility and historic mission, the party's eighteen years, Xi Jinping, general secretary Follow the construction of a series of important speech to the party put forward many new ideas, new conclusions and new requirements, the grass-roots party building work. We should thoroughly study and understand, and consciously assume responsibility. One is to grasp the party building "three questions" of the new requirements. Xi, general secretary of the last 10 August, the party's mass line education practice summary of the General Assembly on the proposed the construction of "three questions". That is: "is not the party committees at all levels and the departments of Party committees (party) to achieve the sedulous catch a party to build is not at all levels of Party committee secretary, the departments of Party committees (party) secretary become strictly administering the party secretary? Is not at all levels and all departments of Party committees (party) Forced members to ‎ fulfill the responsibilities strictly responsibility? "General Secretary of the party building" three questions ", directed at the crucial point, enlightening, three mirror placed in front of everyone, let you according to a photo, see a look, want to think the self-knowledge; is the three pieces of papers placed in front of us, it is clear to judge ourselves whether the party's construction to do their duty. Building" three questions ", urge people to watch, thought-provoking, and convey a strong responsibility to ask signal. The second is to understand the building" three no "new judgment. Xi, general secretary of the party's mass line education practice summary congress pointed out that" history and reality, especially the Are substantially more than 80% of the discipline to move tells us, clear responsibility, fulfil responsibility, accountability, and strictly administering the party is not to ". General Secretary of the" three no ", clear responsibility, fulfil responsibility, accountability, and point out the key. The city public security organs is a member of Communist Party as the main body of troops and members accounted for total number of civilian police, the Bureau of belonging to various departments of leading ‎ cadres and backbone of the party members, the power and responsibility are relatively concentrated in the party's construction, must be clear responsibilities, the implementation of responsibility, accountability, or catch of Party construction is empty. Three is to clear the" three grasping "new initiatives. Xi, general secretary of the strong , catch a party to build must grasp the responsibility system, grasping accountability must catch responsibility, grasping the responsibility must catch the first responsible person. Why should we let Jushu unit party secretary to the party organization at the next higher level debriefing is to implement general secretary put forward "3 catch". To seize the party organization is mainly responsible person, seize the key problem. Second, it is necessary to improve the work of Party building system, the system construction is to strengthen the party building work of public security is an important guarantee. To through the scientific development of the system, improve the system, execution system and make the system become a hard bound, continue to promote the public security work of Party building standardization. One is to further implement the responsibility of Party BuilSystem.‎ ‎ It is necessary to establish and improve Party building responsibility assessment mechanism, at the beginning of the year to progressively signing party builds working target responsibility book. Party organizations at all levels is mainly responsible for comrades to do a good job of Party building as the greatest achievements, adhere to the development wholeheartedly for, to concentrate its attention on the construction of the party, the party building work is included in the important process, and business to work with the deployment, with checks, with the implementation of, true to form Party grasping, Secretary to take the lead in efforts, leaders in charge of specific grab, grab a level, layers of implementation pattern of Party building work. The second is improve the debriefing appraisal system. In accordance with the "debriefing the party building, the appraisal rating of Party building, Party building assessment test, the use of cadres at request of the party", the Secretary of the party debriefing contrast do Law, and constantly improve the annual party debriefing appraisal system, especially to the annual debriefing appraisal evaluation and annual comprehensive examination closely together, the party ‎ builds the job evaluation results into the leading bodies and leading cadres of the annual comprehensive assessment system, strengthen the use of dynamic management and results of debriefing appraisal work, further enhance the debriefing appraisal of scientific, effective and oriented. Third, improve the "three will be a lesson system." three class system is to improve the life of the party organization, strict management of Party member education system must do a good job in the implementation, insist for a long time. According to the "Secretary of the party organization lectures", "Party cadres Implementation of integrating micro lectures and theme day activities, innovation "three class" form, rich "three class" content, pay attention to the work of Party building with the public security work, the formation of "the same resonance frequency, the linkage of communion" party organization life new situation. At the same time, the "three class" of the implementation of join or be admitted to the party secretary of the organization debriefing appraisal of the important content, strict grasp the "three class" system. To strengthen the education of Party members, improve Party member of party spirit idea and political consciousness. Xi ‎ General Secretary profoundly pointed out: "firm ideal and faith are the legal team of political soul must be the ideal and belief education in political and legal team construction of the first , constantly playing firmly hold high the banner, command of the party, loyalty to the mission of the ideological foundation. "The city's public security organs is a with Communist Party members for the disciplined subject, Party members accounted for more than 80% of the total number of civilian police, bureau of belonging to different departments of leading cadres and backbone basically is a party member, do a good job in the construction of Party member team, will seize the fundamental construction of public security team. We must seize the political construction of the police as the core, adhere to the party for public security work absolute leadership this fundamental principle, put the ideal and belief of party spirit education in a more prominent position, to ensure that the Party member troop absolute loyalty, absolutely pure, absolutely reliable. To adhere to the theory of armed, serious organization And adherence to the in-depth study of the majority of Party members and the party's basic theory, especially Xi Jinping, general ‎ secretary of the series of important speech spirit, education of Party members and the party's political discipline and political rules, and consciously in accordance with the party constitution and party political life standards to regulate their own words and deeds, so that discipline, rules, listen to say hello, do in the party party, the party worry about the party, the party for the party, the party retaining the party, and always in the ideological and political action and to Xi Jinping as general secretary of the Central Committee of the party remain highly consistent, consciously do the party's loyal guards of the masses of the people caring people. To build a strong base layer organization, strengthen grass-roots party organization's cohesive force and fighting force. To strengthen the basic level party organization construction Is the key to the target is doing a good job of Party building work of the important basis and guarantee. To optimize the organizational settings. In accordance with the ease of Party members to participate in activities for Party organizations play a role in principle, reasonable norms of the party organization, Party organizations at the grassroots level full coverage, to ensure that each party ‎ members into the party organization in Party activities, organization and management, the organization of care, to accept the supervision of the organization, and actively play a role. Second, we must pay close attention to the team construction. Catch team, with the team party building is an important content and basic level party organization team with members shall complete, clear division of labor, responsibility implementation, implementation of post management. With a good team with a strong Party Secretary , to effectively strengthen the Secretary of the party organization is the Party of person of the first responsibility, sense of responsibility, the responsibility system to prevent "party construction task of Party building, Party building work and business two skins" phenomenon. Third, we need to play good battle fort action. Party organizations at all levels to effectively seize as a key link in the center of the public security work service, adhere to thedingTo the completion of difficult and perilous task as the main battlefield of the work of Party building and the encounter major emergencies and major rescue mission, a major security tasks, the more you want to play the core role of Party organizations, and earnestly ‎ do a good job in the pre war mobilization, wartime motivation, postwar entitled work truly where the battle of Party members and cadres, the party's organizational life extended to where, the role of fighting bastion of the party organizations play where, reflecting the party building work to promote and protect the power. Comrades, in the circumstances to promote comprehensive strictly new situation, do a good job of public security Party Building work as the task is arduous and glorious mission, hope everyone to firmly establish "a game of chess," thought, put down Real strictly required as the new normal organ of the party's construction, further emancipate the mind, ningxinjuli, do solid work, to maintain social stability, promote social fairness and justice, protect the people live and work, to make new and greater contributions.‎ The accident scene of the accident treatment of XX XX, April 7 to April 11, according to traffic police detachment and the traffic police brigade of the arrangement, I had the honor to participate in the Ministry of Public Security Research Institute held high-end training class, by 5 days of training and learning, I have a deep feeling, learning a ‎ lot of new knowledge and to deal with the accident of skills, to learn and work are of great help, we will experience is summed up as follows: first, study the new knowledge, to expand the field of vision. In the research the teacher to explain, we review the < road traffic accident scene drawing >, and emphatically studied at the scene of the real record drawing standards, the graph can reflect the state and each element Full coverage regardless of size, position, give a person to live a more intuitive understanding of the next step accident treatment has a great help. At the same time, I have seen some new accident investigation equipment, such as a new generation of traffic accident scene drawing system, through training, the police can very fast rendering standard site map, data measurement, and in accordance with the Ministry of public security of the standard, and the UAV, the application of UAV camera or camera, from the fundamental solution overview accident photos. Second, on the scene photography basic requirements and accident photographic difference. The scene photography scene is the most objective real reaction. But photographs of the scene taken to ensure objective, comprehensive, timely and clear requirements,‎ ‎ this scene photos to assurance its legal effect; the scene photography has also undergone a change by the original photography of orientation and overview of photography, Photo Center, breakdown of the photo, change for range photography, photographic overview, local camera, film element, photography of minutia, than photography, so to photographic content more refined, more specific, the as evidence of a more targeted, more accurate., on site survey extracted traces and field exploration process traces are extracted by the problems and errors. Trace on the scene of the discovery and extraction as a matter of So the scene investigation is an important part of the process, on the analysis of the cause of the accident and the accident are very important role, through the teacher's explanation and analysis them as an expert, from the perspective of identification of traces of the scene points extraction and pointed out the direction for under our own exploration site to extract traces, at the same time, through the teacher's explanation, accidents will produce certain traces, which requires us in the scene of the accident investigation of careful, and not missing any useful to our trace on the scene. On advanced equipment of traffic ‎ accident identification, genetic analysis of the role of. I feel the deepest is now home Car safety air bag with something called the airbag module. This is known as "black box" car equipment, has a record of when the speed, whether to take braking, take a few braking and other data, recording, has a very large role for analyzing the cause of the incident, next serious accidents must pay attention to extract such equipment; and escape accidents are common in the general video surveillance on the blurred image, wLicense plate number; shellac, fiber identification, etc. with advanced equipment can make the identification, with the advanced equipment, technical backing, feeling the impartial handling of the each accident and escape detection accident confidence. On the scene of the accident protection. The teacher from three aspects to explain the road traffic accident and law enforcement duty site safety protection: 1, from the level of laws and regulations, Ministry of public security, proceeding from the actual conditions promulgated on the rules and regulations to strictly enforced, which requires each of us a police starting from their own point of view, for their own safety, must not omit any link, don't be afraid of trouble, this is ‎ Lists are not qualified for you alone are responsible for the unit is responsible for the family is responsible for; 2. Strengthen on-site protection facilities of the configuration and use, the first to buy and configuration of safety protection equipment, if equipment, but also about what door? Then is another question, equipment, how to use, the teacher of Tianjin accident lesson, because a lot of equipment, is not put into use, resulting in our police due to the lack of timely reminder of the accident, causing us to a number of police casualties; 3, the device is put into use, but also strengthen individual protection skills and teamwork training. In a word, We want to use qualified equipment and abide by laws and regulations, strengthen training of personal skills and teamwork and ensure its own security in the field staff. Through the study of five days of training, an increase of knowledge, learning the something new, strengthen the unit and brother of business flow, also found their own shortcomings, the next step I want to share of Wuxi advanced concepts and colleagues, common learning and common progress, makes the traffic police brigade accident treatment work more on the floor!‎ In recent years, XX city always adhere to a hand grasping the building, a hand grasp the management, and actively explore new mode of Biogas Service, strive to innovate new mechanism for ecological compensation, pay attention to enhance the image of the new energy team, cohesion to create a new bright spot of circular agriculture, biogas in scientific management, comprehensive utilization and achieved certain results.‎ First, the cultivation of new business entities, to explore new mode of follow-up services XX city has been built biogas 11 million households, biogas digesters is "treasure pool, biogas replaced the coal and firewood, become a clean, economic life energy, biogas pool instead of the old cesspool, become to improve the sanitary conditions of important possessions. With the maintenance quantity is increasing year by year, firedamp follow-up service into the long-standing problem.‎ To do a good job of Biogas Service, polish up the brand ‎ of "XX model and we guide biogas mechanic established biogas cooperation, energy service companies, such as the model of market main body. Through market service, breakthrough in the past by the government construction, maintenance, a pack in the end of the narrow concept, establish the" who benefits, who management "the correct concept. The main body of the new take innovative service mode, expand service content and other measures, developing biogas service, centralized gas supply pipeline construction and gas charging operation and other aspects of comprehensive management. It not only solves the problem of farm household biogas, and change the follow-up services, but also increases the income of service team. The cultivation of new subjects, to consolidate and improve the service system, the effective establishment of a long-term mechanism of biogas services, to achieve the standardization of the follow-up services, intensive and professional.‎ Two, the introduction of international carbon trading, innovative new mechanism for ecological compensation XX City Xiang Bai Guo centripetal rich is an ordinary farmers biogas, biogas his home with very good results, he is carbon fund project of farmers, this year, the winner of the Netherlands government to pay him thehich can identifyInspired by the introduction of $23, he used this carbon trading income to buy a new gas stove. This is XX household biogas clean development mechanism project is the United Nations first successfully registered household biogas carbon fund project. The project of 4330 household biogas pool, each year to reduce carbon emissions in 7298 tons, carbon emissions trading income of 10 million US dollars, equivalent to RMB 65 million yuan, carbon trading income subsidies to build pool farmer for biogas digesters follow-up maintenance provides ongoing capital investment in carbon fund project, XX City, the implementation of the "gas rewards" project, "whether the normal ignition, gas pressure size, pig herds head number Indicators will biogas digester using effect is good, medium and poor to refine the management and posting the use of farm household biogas, biogas use good farmers reward. Ecological compensation project implementation, increase the income of farmers, mobilize the enthusiasm of farmers, increase rate of the ‎ use of biogas, at this stage for the implementation of the voluntary emission reduction projects to provide a reference.‎ Three, establish an advanced service model, highlighting the new image of the energy team Repeatedly since the technology of biogas digesters "third built seven in charge, not good will be" a year, two years, three years four years keep frogs. To catch the follow-up service, to catch the team XX City in strengthening the team building process, the emergence of a number of service models and technical experts. Dragon and Phoenix Town Agricultural Service Center of Yuan Liang, is a typical representative. He from 2005 years engaged in gas, ten years as one day, always keep the people of noble sentiment, conscientiously perform their duties conscientiously serve the masses. His advanced deeds of people's daily, the farmer daily, Hubei Daily and other media reported that 2015 was named the provincial labor Model, by the Deputy Secretary of the provincial Party committee Zhang Changer as the new era of Shi Chuanxiang,‎ ‎ Yuan Liang with his dedication to the cause of the gas, won the majority of people good reputation.‎ Vigorously promote the typical deeds, strengthen the play. Incentive motivation, the city "for everyone to learn advanced, all vying for the advanced, everyone catch up with and surpass the advanced" has become so rampant, the team has the typical, post a pacesetter, set up the city's rural energy team for the good image of the civil service.‎ Four, to promote the development of circular agriculture, build a comprehensive utilization of a new bright spot Table, an important role in the profound understanding of the ecological "XX" from the ecological agriculture, XX city to biogas development of ecological agriculture, always adhere to the construction of biogas energy line overall circulation agriculture demonstration, in accordance with the "gas into people's homes, free installation, according to the charges, comprehensive utilization" principle, vigorously carry out the centralized gas supply, recycling for the purpose of biogas ‎ engineering construction. One is to carry out multi demonstration. The dragon and Phoenix Town, Tun Xiang Bai Guo Xiang, the construction of the biogas engineering as a link to the "pig - biogas - vegetable", "pig - biogas - tea", "pig - biogas - fruit" cycle of agricultural demonstration base, through a variety of experiments and demonstrations, summarize test result And promotion of demonstration experience. The second is to enhance the quality. The city in biogas production and utilization, research and development of "high yield biogas fermentation device and selenium enriched biogas fertilizer production method" is State Intellectual Property Office of the grant of the patent right, to enhance the level of technology of the city of Biogas fertilizer use. The third is to expand the use of the area. According to local conditions, due to implement the strategy, the follow-up services of biogas and biogas comprehensive utilization of organic combination, to solve the "planting no biogas pool", "biogas pool or not in the labor force", practical problems such as "labor without cultivation", let biogas fertilizer was in circulation and utilization.‎ The next step, XX city will in accordance with the provincial, state energy deployment, and further increase the efforts to the construction of biogas project, to accelerate rural biogas to the scale of development, comprehensive utilization and scientific management in the direction of transformation and upgrading, promote the sustainable development of biogas in rural areas.‎ In recent years, under the support and guidance of the provincial rural energy office, the county completed a total of household biogas pool nearly 7 million households, large-scale biogas project 4, small and medium-sized biogas project in 141, rural service outlets 211, subsidies for solar water heater 2340, biomass stove 2300 units, for the development of green agriculture, improve the people's quality of life play great role. In particular, we succeed in biogas purification, high value utilization based on, to further expand the scale, to open up the market, standardized management, to promote the transformation and upgrading of rural biogas project made some active exploration. Our approach to report as follows:‎ One, scale development, play the economic and social ‎ benefits of high quality of methane utilization Biogas high-quality exploit inspired new rural of our country's energy market, for installation of gas pipeline engineering of new rural residential demand. Since last year the province's rural biogas high quality using after the spot, we based on the basis, to expand the scale, an ample supply of gas source, to ensure that farmers with adequate quality of bio gas.‎ One is to expand the size of the original base. Last year held a spot of Qianfeng county and in the province of rural energy office, county government support, in the original 30 acres of the project on the basis of, to ratify the new 10 acres of land, according to large scale biogas centralized gas supply engineering construction requirements, invest 100 million yuan to build a 3000m3 volume of anaerobic fermentation tank, the implementation of technical innovation, using carbon steel output pipeline, building to gas 10000m3 above the new holder, and complete the related projects, assurance that have been developed to farmers with the supply of gas, 2016 Spring Festival peak ‎ gas during. There have been no interruption in supply, the user of ten Satisfaction.‎ Second is to actively open up new bases. This year, we through the comprehensive deployment of the county government, related to the integration of sector funds, in Pu Zhen Zhang Zhuang Songlin farm, the port town of gold farming cooperatives, plans to build two 2000m3 volume fermentor, copy forward mode, solve environmental pollution, fruit trees fertilizer, life problems with gas. We will also under the support of relevant departments, the forward mode is launched county public security, with conditions in other counties, willingness of biogas engineering base, to assist in the construction of gas compression purification equipment and production and marketing integration mode. At present, Qianfeng company has been declared a biogas purification, compression and canning 10 a number of utility Technology patents, 2 invention patents, has applied for a registered trademark of the striker, and with the equipment manufacturers to improve the equipment stereotypes and production and business license related work.‎ File, identity to access to a wide range of measures to implement a decentralized, and third, we will steadily develop the market, we forward the company together to form a team, the public security county, Nanping, lotus pond gate three town residential area development, joint concentrated propaganda, further mobilize and organize farmers to base inspection, to the user, enhance the perceptual knowledge, so that the majority of users of biomass gas from ignorance, doubt, and the safe, convenient, economical and practical advantages of convinced, blown away. At the same time, begin to rural area market development, Meng Zhen Jin Gang Cun Zha Kou Zhen De Yi Village pilot, the biomass gas supply farmers, let old people's lives improve grades. Popular support, this year, has added 2382 users. In the commercial sector, has also developed more than 10 food and beverage industry users, the amount of gas is equivalent to 500 civilian gas consumption.‎ Two, make an inventory of the stock, to play the role of high quality of the use of Biogas Rectification has been built in the biogas project, the use of mobile integrated compression purification equipment, the nearest gas recovery, the nearest distribution, improve the use of the original biogas project effect, give full play to the role of high quality and revitalize thProvince's rural marsh gas with high quality use after the spot, we organized a special group, on the basis of a full range of investigation and research, and forward the company together on the county's three large and medium-sized anaerobic fermentation tank be renovated and through technical transformation to restore gas production capacity, building integrated mobile compression purified gas recovery equipment, gas recovery at the price of one yuan per cubic meter by striker company recovery. Both sides have certain economic benefits, not only start the utilization of waste fermentation tank, but also saves the cost of new fermentation tank, achieve a win-win results.‎ Transformation of concentrated residential above at the same time, we also the county nearly 20 100m3 volume fermentation tank, technological transformation, the use of ‎ forward the company's equipment, so that to make full use of the conditions are ripe for the District, we use small equipment for purification of direct supply, the use of the user directly with clean and high quality raw material gas, deeply welcome. For example, we in Zhang Tian Si Zhen Chang Chun Cun residential area gas investment less than 20 million yuan, to more than 100 users for the natural gas. Through the entire old buildings and building new, one or two years to cover the whole county, and truly let the rural biogas upgrading work implemented, resulting in greater social benefits and economic benefits. ‎ Three, comprehensive utilization, to play the key role of biogas project to boost green agriculture Consumptive striker in my county is planting, livestock and poultry, aquatic County, according to statistics, the county pig herds 57 million head, poultry kept caged 9.7 million, large-scale farms and farming district more than 1000, animal manure and sewage emissions 20 million tons, aquaculture and environmental protection pressure. In the county government's support, we have more channels to raise ‎ funds, the biogas project near the base of the five towns more than 20 a livestock and poultry farm manure renovation to achieve separation of dry and wet, and each farm road repair, the company and the aquaculture field signed agreement, the implementation of paid service. On the one hand, to solve the environmental pollution problems, to ensure that the livestock and poultry breeding The healthy development of the industry, on the other hand, to ensure the Qianfeng company production of biomass gas raw materials, can effectively reduce the cost. In the treatment of biogas slurry and residue, we equip the a full automatic drip injection and spraying fertilization system, biogas slurry destined for the vegetable fruit base, through the pipe network, the use of automation in process of sprinkler irrigation and achieve small investment, big gains in effect.‎ Combined with biogas centralized supply through the establishment of biogas households, biogas comprehensive utilization demonstration area, fan out from point to area, to expand the scale, give full play to the commercial, biogas fertilizer fertilize the soil effect. Comprehensive ‎ utilization of agricultural structure adjustment to construction of biogas as a link, promote aquaculture, driven by planting industry development, and vigorously promote the "pig - Marsh - fruit, pig - Marsh - food, pig - Marsh - Fish" green mode, to create eco brand, organic brand. Over the past two years, we met with Xing Long ecological farm, Dorian vegetable cooperatives and Jin Gang grape base jointly invested more than 30 million, to build three "three natural ponds" comprehensive utilization project pilot, the economic benefit is obvious, vegetable growers of identity And praise.‎ Although we have done some work on the use of biogas in high quality, but according to industry standards and market operation requirements there are many procedures need to complete, we urge the department pay more to give guidance and support, to ensure that rural biogas high-quality use of standardization, scale, standardization and rapidly to the province, and strive to promote the country.e stock.‎
