摘要
对均匀带电圆盘和正多边形面盘、圆环和正多边形环以及含圆孔、正多边形的无限大平面中心垂轴的电场分布进行了计算,并对所得解析结果进行了对比。通过模拟,得到圆盘、圆环均匀带电平面中心垂轴电场分布图,尤其是不同环面宽度的中心垂轴场强分布;对模拟结果进行了分析及总结。正多边形的面盘、环的模拟结果具有相同的结论。通过对比,加深了对各种规则形状带电平面中心垂轴电场差异性的认识。
First the electric fields at the vertical shafts of the regular-shaped uniformly charged planes centers were calculated, the regular-shaped planes covering the circular and regular polygon plates,the circle and regular polygon rings and infinite plane with circular hole or regular polygon; the obtained analytical results were compared. Then the uniformly charged d isc ,the annulus center vertical axial electric field distributions were simulated; especially so were done the electric field intensity distributions at the ring central vertical axes under different ring width ; similarly it could get the simulation results of the regular polygon p late, ring. Finally, the simulation results were analyzed and the differences between the electric fields of vertical shafts to various shapes charged planes centers were summarized. By contrast,a deep understanding about these differences was obvious.
