| 摘 要： | 根据电场叠加原理,利用Matlab的绘图功能,绘出二维平面内点电荷系的等势面和电场线。以三个点电荷为例,模拟了它们的电场线和等势面,并通过改变电荷的位置和电荷量的大小对电场的分布情况进行分析比较,在教学中能起到很好的演示作用。

| Abstract: | According to the principle of potential superposition of point charge system and electric field lines perpendicular to the equipotential surface, combined with graphics capabilities of Matlab, plotted equipotential surface and electric field lines of Point Charge System in the two-dimensional. It takes three point charges as an example, simulated their electric field lines and equipotential surfaces, and analysis and compare the distribution by changing the location and the amount of electric charge, it can play a good role in teaching demonstration. |
