浅论正多边形带电环 盘 筒 柱的场强

Brief Discussion on the Electric field Strength of the Regular Charged Polygon Ring,Dish,Cylindrical Surface,and Cylinder

根据文献[3]提供的公式，基于场强叠加原理，系统解析计算了正多边形带电环、盘、筒、柱中轴线上的电场分布，结果表明不同带电体的电场强度的代数性质与其电荷分布密切相关．从所做的几项计算中显示，环优于盘，筒优于柱．

Based on the superposition principle, the charge distribution on the axis of regular charged polygon ring,dish, cylindrical surface,and cylinder are calculated systematically. The results show that the algebraic property of electric field strength of different charged body is closely related to its charge distribution, i. e. , the ring＇s is better than the plane＇s, and the cylindrical surfaee＇s is superior to the cylinder＇s.
