摘要
电场线可形象化地描述电场分布的情况.用MATLAB这类软件虽可方便地画出电场线,但其前提条件是首先要得到电场线方程.两个点电荷及有限长线电荷很难通过求解微分方程得到电场线方程.本文根据对已知的电场分布及电力线基本性质的分析,得到此两类电荷分布体系的电场线方程.
The electric field lines enable us to describe visually the distributions of the electric field. At first, the equations of the electric field lines should be obtained in order to plot conveniently the electric field lines with software such as MATLAB. It is difficult to obtain the equations of the electric field lines of two point charges and a finite long line charge distributions by solving the differential equations. Based on the given electric fields and the essential properties of the electric field lines, the equations of the electric field lines for this two kinds charge distributions can be obtained.
