摘要
通过求解电场线所满足的微分方程,得到了沿直线分布电荷体系电场线的严格解析解,根据所得电场线簇方程,讨论了各种沿直线分布电荷体系的电场线特点,并在计算机上利用Mathematica软件绘出了相应的电场线分布图.
Analytic solutions are obtained by solving the differential equations for the electric field lines produced by lined-up charges. The characteristics of field lines are discussed on the basis of the solutions for the equations. Also the graphs of field lines are drawn with Mathematica soft ware on computer.
