线电荷和无限长介质圆柱壳系统电势的计算和讨论

摘要

计算了线电荷和无限长介质圆柱壳系统的电势分布，指出线电荷与介质圆柱体、线电荷与导体圆柱壳、均匀外电场中有无限长介质圆柱壳系统的电势分布都可由线电荷和无限长介质圆柱壳系统的电势给出。%The electric potential distribution of a system for linear charge density and long-dielectric column shell is calculated by using the separated variable method and some useful calculations are presented.
