该如何用电像法处理导体球腔

How to Deal with Conducting Spherical Cavity by Electric Image Method

为解决导体的静电感应中,导体球腔与点电荷组成的孤立体系的感应电荷分布以及电势等相关问题,建立在唯一性定理的基础上引入电像法,先证明电像法的正确性,接着分别从点电荷位于球腔外与球腔内利用电像法研究电荷分布与电势问题,最后通过一道例题巩固电像法的使用.

To solve the problem of electrostatic induction of conductor,the conductor ball cavity and satisfies the induced charge distribution and potential of the isolation system consisting of related problems,based on the uniqueness theorem of introducing method of electricity image,to illustrate the correctness of the method of electricity image like first,then respectively from the point charge in the ball outside the cavity and cavity charge distribution are studied by using electricity as method and potential problems,finally,an example is given to consolidate the use of the electric image method.
