摘　　要：通过电像法给出了带电细圆环在导体球壳内的"镜像",再根据(连带)勒让德多项式的性质和加法公式,利用叠加原理计算出了带电细圆环与导体球壳系统的空间场分布.该方法简便易懂,适用于求解轴对称性稳恒场的分布.With the method of images,the ＂mirror image＂ of a uniformly charged ring in a conducting sphere is studied.According to character and additive formula of Legendre polynomial,space electric field distribution of a system consisting of a charged ring and conducting sphere is calculated by superposition principle.This method is easily understood,and is applied to solving the distribution of axial symmetric static field.
