对一对等值同号电荷电力线图的探讨

A Study on Graphs of Electric

本文对国内外许多普通物理教材中所给出的一对等值同号电荷的两种不同形状的电力线图进行了分析,从而指出这两种不同的电力线图实质上都是正确的,而在这些教材中对电力线性质的归纳却是不完备的,忽视了奇异点的特殊性。

The present article analyses the two different graphes of electric line of force for a pair of the same charge given in many general physics textbooks both at home and abroad. Furthevmore, the article points out thaf the two different graphes of electric line of force are both correct in nature. Therefore , the discriptions on the nature of electric line of force are not perfect in these textbooks and ignores the special nature of the irregular point.
