摘要
本文以数学和物理相结合的方式,建立了关于电荷系统的物理图象:电荷系统是由中心位于坐标原点的各级多极子迭加而成。在这个基础上针对理解电势多极展开式中的一些代表性问题作了说明。并从一个新的起点开始,导出了电势的多极展开式。
In this paper,we establish physical image of elecric charge system by combining mathematics with physics:electric charge system be composed of superposition of multipoles.A new method of explore electric multipoles extended is given,a formular of electric potential multipoles is derived and some representative problems are discussed.This method make the students easily understand multipoles and be helpful to electrodynamics teaching
