两种绘制一维点电荷系电场线方法的比较

Comparison of Two Methods for Depicting Electric Field Lines of One-dimensional Point Charge

通过点电荷电场中接地导体球面上的电荷分布,对两种绘制一维点电荷系电场线方法进行比较,指出各自的优势和不足.

By the electric charge distribution on the surface of an earthing conductor ball in the electric field of one point charge,two methods for depicting electric field lines of one-dimensional point charge are compared,and their advantages and drawbacks are pointed out repectively in this paper.
