摘　　要：利用格点法模拟静电场在二维平面内的电势分布.具体描绘了点-点、点-线、线-线,以及同心圆环的静电场等势线分布情况,并与理论计算结果进行比较。同时还分析了同心圆环产生的电势与同轴圆柱面产生的电势的区别。The electric potential of electrostatic field is described by lattice method in two dimensions. The distribution of equipotential lines in electrostatic field for point-point,point-line,line-line,and concentric rings are described,and the calculated results are compared with theoretical value. The different between the two electric potential lines for concentric rings and centric cylinders is investigated.
