有限长带电直导线的电荷不可能均匀分布

The Uniform Distribution of Charges is not the Characteristic of the Finite Charged Straight-line Conductor

本文特别讨论了有限长带电直导线的电荷分布问题,用简单的方法证明若有限长带电直导线电荷均匀分布,则带电直导线上的电势逐点变化,不符合导体静电平衡时为等势体的特征,因而证明有限长带电直导线的电荷不可能均匀分布.

In this paper,the distribution of charges for the finite charged straight- line conductor is discussed specially. It is demonstrated with easy way that if the distribution of charges for the finite charged straight - line conductor was uniform,the electric potential for the charged conductor line would vary from point to point,and it would be not in accordance with the property of equipotential for conductors. Therefore,the distribution of charges for the finite charged straight - line conductor is non - uniform absolutely.
