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.

关键词: 电场线, 解析解, 计算机绘图

Abstract: 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.

Key words: electric field lines, analytic solution, computer drawing
