摘要
本文通过取电场线管和两个断面组成的高斯面,用高斯定理推导出了共线点电荷系的电场线方程,该方程能推广到一般的共线电荷系.用计算机软件画出了几种典型的共线电荷系的电场线.
In this paper,based on the Gauss law,the equation of electric field line of collinear point charge system was obtained by calculating the expression of electric flux passing through a section of a electric field tube.This equation can be extended to the general case of linear charge distribution.Several kinds of typical electric field lines were drawn by the Mathematica software.
