摘要
依据静电场中点电荷电场强度和电势的定义 ,讨论了等量同号和等量异号点电荷中垂线上电场和电势分布的特点 ,得出结论 :等量同号点电荷中垂线与该电荷系统的电力线重合 ;中垂面上电力线呈辐射状分布 ;等量异号点电荷的中垂线是该电荷系统的等势线 ,中垂面是等势面 .
Based on the characteristic of the electric line and equal zeta potential line in electrostatic field, this paper discusses the special significance of the perpendicular bisector of particle charge of the same and different sign under equal quantity, this is the perpendicular bisector of particle charge of the same sign under equal quantity is electric line ,while the perpendicular bisector of particle charge of different sign under equal quantity is equal zeta potential line.
