At present, the County personnel totaled 93,000 people, is three times times of 2010. Review the work of the past five years, the County formed to encourage innovation, innovation, participation in innovative atmosphere, a large number of innovations emerging high-level personnel leading the increasingly strong role; innovative idea further innovations gradually expanded from economic to social governance, public safety, intelligence and other areas of urban construction, innovation and talent support becomes increasingly important. Of hard work, the county levels to cherish, continue to consolidate, improve and, for the future development, to remain sober-minded, scientific foresight, courage to play. Under the influence of complicated international and domestic situation, the domestic economic situation, and General Secretary of stability, but downward pressure on large trend of differentiation and deepening of structural adjustment sums up the current situation. From Dongping actual see, Thirteen-Five during, County faced stable economic growth, and deepening structure adjustment of double task, both faced with economic total small, and per capita level low, and industry structure not reasonable, and economic development way extensive, basic situation, more has industry cluster early now prototype, and Park hosted capacity constantly enhanced, and resources traffic location advantage increasingly appeared, and cadres masses innovation venture passion 【人教版】选修3-2 第六章第2节传感器的应用同步教案适用学科高中物理适用年级高中二年级适用区域人教版课时时长（分钟）60分钟知识点传感器的应用教学目标1、知识与技能 （1）了解两个实验的基本原理； （2）通过实验，加深对传感器作用的体会，培养自己的动手能力。 2、过程与方法: 通过实验培养动手能力，体会传感器在实际中的应用。 3、情感态度与价值观: 在实验中通过动手组装和调试，增强理论联系实际的意识，激发学习兴趣，培养良好的科学态度。教学重点了解斯密特触发器的工作特点，能够分析光控电路的工作原理。温度报警器的电路工作原理。教学难点光控电路和温度报警器电路的工作原理。 教学过程 一、复习预习 复习：1，传感器的工作原理 2，传感器的分类 二、知识讲解 课程引入： 随着人们生活水平的提高，传感器在工农业生产中的应用越来越广泛，如走廊里的声、光控开关、温度报警器、孵小鸡用的恒温箱、路灯的自动控制、银行门口的自动门等，都用到了传感器．传感器的工作离不开电子电路，传感器只是把非电学量转换成电学量，对电学量的放大，处理均是通过电子元件组成的电路来完成的。
