摘要
为了了解空间各点电场强度的大小和方向,需要借助于电力线或等势面.研究了由电势叠加原理计算出点电荷对的等势面方程,由高斯定理计算出点电荷对的电力线族方程,并用Mathematica软件作出了相应的图.该方法简单、准确.
Drawing electric field lines or equipotential lines are very useful in visualizing electric field strength and direction. In this paper, equations for equipotential lines produced by two charged points are derived by superposition principle,e quations for electric field lines produced by two charged points are derived by Gauss law and the computer draw the lines. This method is simple and exactitude.
