摘　　要：在保角变换的基础上,给出由C-R条件及静电场的复势求解二维复杂静电场的电场线方程的方法,并利用MATLAB软件绘制出其电场线与等势线(面)分布图.Based on conformal mapping,the two methods of solving electric field line equation in two dimensional electrostatic field by the Cauchy-Riemann condition and the complex potential of electrostatic field are given.Further,the electric field lines and equi-potential lines are plotted by MATLAB.
