摘要
在产生静电场的电荷之间作用着静电力.库仑定律可以计算两个点电荷之间的力,但对更为复杂的带电系统,用库仑定律去计算其中一个物体受到所有其他物体上电荷的作用力是很麻烦的.本文从系统的静电能入手,讨论充电系统中某一物体上所受到的静电力,并介绍静电场的应力张量.
There exists some electrostatic force between electrical charges with electrostatic forces. Coulomb's law can calculate the force between two points of electrical charge, whereas it is a troublesome way to calculate the force of one object on the other in the more complicated. Through the electrostatic energy of system, the electrostatic force of the object of the system of charge is discussed and the tensor of stress of electrostatic field is presented.
