摘要

采用直角坐标系,基于椭球表面方程的特点,设计一个电势的“尝试解”,根据电场“唯一性定理”的要求,找到该“尝试解”满足的方程,通过求解该方程得到带电导体椭球的电势分布.

Abstract

Based on the characteristics of ellipsoidal surface equation,a trial solution of the electric potential is designed in the rectangular coordinates.According to the uniqueness theorem of electric field,the equation of the trial solution is found and then the potential distribution of charged conductor ellipsoid is obtained by solving this equation.
