均匀带电球面和长直圆柱面上一点的电场强度

About the Electric Field Intensity on a Point of an Even Electric Field Spherical Surface and a Long Straight Cylinder Surface

根据叠加原理，求得了均匀带电球面上一点和长直圆柱面上一点的电场强度，并提出现行教材中对上述带电体系电场强度分布的讨论应遍及空间所有点，同时给出正确的函数图。

Based on the principle of piling up,the electric field in tensity on the surface of long circular and the point on the spherical surface with even electricity have keen settled.Also,this paper points out that the present text should start out a discussion that all the points of the system talked above should be evenly distributed and gives out the correct functions at the same time.
