摘　　要：本刊2018年第10期刊登了“带电厚椭球壳空腔内的电场”一文,文中研究的厚椭球壳是由非导体构成的,其内表面和外表面分别是二个共轴的、等偏心率的椭球面.该文仅计算其空腔内的场强,本文是该文的继续,采用对比方法和电势迭加原理计算其空腔内的电势,并顺便求得均匀带电椭球中心的电势.We calculate the electric potential inside the cavity of a uniformly charged thick ellipsoidal shell.This shell is composed of non-conductor.Its inner and outer surfaces are two coaxial ellipsoidal surfaces with the same eccentricity ratios.The electric potential in the cavity is calculated by using the comparison method and the superposition principle of the electric potential,and the electric potential in the center of the uniformly charged ellipsoid is obtained by the way.

关 键 词：椭球壳 电荷 电势 迭加原理 对比方法
