静电场本章研究的是电磁运动中最简单的情况静电场，所采用的研究方法为：从库仑定律开始，建立静电场的概念，从置于电场中的电荷所受的力和力做功的情况，研究静电场的性质，引入电场强度和电势两个重要的物理量。建立场强叠加原理、高斯定理、环路定理等。一、概念静电场：任何电荷周围都存在着电场，相对观察者为静止的电荷所激发的电场。电场的特点(1)电荷之间的相互作用是通过电场来传递(2)对位于其中的带电体有力的作用(3)带电体在电场中运动,电场力要作功 电场是种物质，具有能量、质量和动量。电场强度：放入电场中某点的电荷所受静电力 F跟它的电荷量比值，叫做该点的电场强度。定义式：E=F/q，F为电场对试探电荷的作用力，q 为放入电场中检验电荷（试探电荷）的电荷量。电场强度的方向：规定为放在该点的正电荷受到的静电力方向。与正电荷受力方向相同，与负电荷受力方向相反电场力：电荷之间的相互作用是通过电场发生的。只要有电荷存在，电荷的周围就存在着电场，电场的基本性质是它对放入其中的电荷有力的作用，这种力就叫做电场力判断方向方法：正电荷沿电场线的切线方向，负电荷沿电场线的切线方向的反方向。计算：电场力的计算公式是F=qE，其中 q为点电荷的带电量，E 为场强。或由 W=Fd，也可以根据电场力做功与在电场力方向上运动的距离来求。电磁学中另一个重要公式 W=qU（其中 U 为两点间电势差），可由此公式推导得出。静电力作功的特点：单个点电荷产生的电场中任意带电体系产生的电场中电荷系 q1、q2、的电场中，移动 q0，有结论：电场力作功只与始末位置有关，与路径无关，所以静电力是保守力，静电场是保守力场。电通量：通过电场中任意给定面积的电场线的数目，叫做通过该面积的电场强度通量，简称电通量。（它是研究电场性质的常用物理量）公式：电通量密度是通过垂直于电场方向的单位面积的电通量，它等于该处电场的大小E。电通量密度精确地描述了电力线的疏密。dSEdsese?文档编码:CR5L9C3A3K4

点具有的电势能。公式：a.离场源正电荷越近,试探正电荷的电势能越大,试探负电荷的电势能越小b正电荷顺着电场线的方向移动时,电势能逐渐减小,逆着电场线的方向移动时,电势能逐渐增大负电荷顺着电场线的方向移动时,电势能逐渐增大,逆着电场线的方向移动时,电势能逐渐减小c.无论正负电荷,电场力做正功,电荷的电势能就一定减小,电场力做负功,电荷的电势能就一定增加说明(1)电势能应属于q0 和产生电场的源电荷系统共有。(2)电荷在某点电势能的值与零点选取有关,而两点的差值与零点选取无关(3)选势能零点原则：当(源)电荷分布在有限范围内时，势能零点一般选在无穷远处。无限大带电体，势能零点一般选在有限远处一点。实际应用中取大地、仪器外壳等为势能零点。电势：处于电场中某个位置的单位电荷所具有的电势能。电势只有大小，没有方向，是标量，其数值不具有绝对意义，只具有相对意义。公式：C、电势差：在静电场中任意两点a、b 之间的电势差，数值上等于把单位正电荷从点 a 移到点 b 时，静电场所做的功。公式：dlEqEapa?参考点0?参考点aadlEU?babaabdlEUUU文档编码:CR5L9C3A3K4 HF2U1Z1Z4N1 ZW6C8E7B9E5文档编码:CR5L9C3A3K4 HF2U1Z1Z4N1 ZW6C8E7B9E5文档编码:CR5L9C3A3K4 HF2U1Z1Z4N1
