用相对论方法对电磁学有关问题的探讨

A Research on Several Electromagnetic Problems by Relativity Method

本文从相对论的观点出发,应用洛仑兹变换式和电磁场的变换式,讨论了运动电荷的电磁场问题,同时根据高斯定理在洛仑兹变换下的协变性,讨论了引出位移电流概念的一种方法.

Using Lorentz transformation and electromagne tic field transformation, the electromagnetic field produced by moving charge is discussed from the viewpoint of relativity.According to the invariance of Gauss's law under Lorentz transforma tion, a method to introduce the concept of displacement current is discussed also.
