【摘要】 通过求解球坐标系中电势所满足的拉普拉斯方程和叠加原理,给出了带电细圆环和均匀介质球系统的电势分布解析式,根据此解析式用Matlab软件绘制等势线,并对求解结果进行了讨论,得到介质球球心、远区、系统轴线上以及带电细圆环和导体球系统的电势分布.更多还原

【Abstract】 By solving Laplaces equation in spherical coordinates and using superposition principle,we get the expression about potential distribution of a system composed of a charged ring and dielectric spheroid,and plot the iso-potential line by Matlab.Based on the results,the electric potential distribution around the dielectric sphere center,the far zone,the system axis,the charged ring and the conductor ball system are obtained.更多还原
