基于Origin的一维电荷分布系统的静电场模拟

Electrostatic Field Description of One Dimensional Charge Distribution System Based on Origin

以几种一维电荷分布系统为例,推导出它们的电场线方程及等势线方程,利用Origin软件的矩阵功能建立表征电场线及等势线分布的数据矩阵,再利用Origin的绘图功能绘制出电场线和等势线的仿真图形。结果表明,用Origin模拟静电场无需编程、简单易用,所得仿真图形准确、美观。仿真模拟既可以为静电场的课堂教学提供直观便利的认识,弥补传统教学手段的不足,又可以进一步加深学生对静电场分布规律的理解。

Taking several one-dimensional charge distribution systems as an example,the electric field lines and potential linear equations are firstly deduced. Then,the data matrix of the distribution about these curves is established by using matrix function of Origin software. Finally,the graphics of these curves are drawn by using Origin. Our results show that it does not need to program for simulation by Origin,this method is simple and easy to use,and the simulation figures are accurate and beautiful. The simulation can provide an intuitive and convenient understanding to the classroom teaching of the static electricity field,thus this can be used for overcoming the shortcomings of the traditional teaching method. Furthermore,it can deepen the understanding of the distribution of the electrostatic field.
