无限大均匀带电平面的电场均匀性的原因分析

The Analysis for Reasons of Electric Field Uniformity For the Infinite Evenly Charged Surface

在真空或无限大均匀电介质中,无限大均匀带电平面的电场强度处处相等,和场点距离该平面的远近无关.本文从数学关系和物理机理上,探讨了该平面上“峰值圆”和任意圆内外电荷的垂直分场强的不同性质,进而剖析了该电场的结构和上述匀强性的缘起.

In the vacuum or infinite evenly charged dielectric materials,the field strength of its surface equals at all spots.And it has no relation with the distance of the field spots to the surface.Through mathematical relation and physical mechanism,this paper investigates the different nature of the vertical partial field strength of the inside and outside charge of the “pe- ak values circle”and the random circle on its surface,giving a further analysis of the structure of the charged field and the reasons of the uniformity above mentioned.
