用模拟电荷法求解无限大地面上封闭空心金属圆筒的电容

Calculation of the capacitance of the system of the hollow medal cylinder to the perfect infinite metallic ground through the CMS

简述了模拟电荷法的基本原理,并用金属球壳——无限大理想金属地面模型的解析解和金属平板——无限大理想金属地面模型的渐进解,分别验证了模拟电荷法对于求解这类电容问题的正确性,最后用模拟电荷法求解了封闭空心金属圆筒——无限大理想金属地面系统的电容,给出了电容随三个参量变化的曲线族,并对曲线族进行了分析。

The of the system of the holl of the charge simulation method briefly is introduced, and through the analytical expression ow sphere to the perfect infinite metallic ground and the imminent expression of the system of the plate to the perfect infinite metallic ground. It is known the validity of the charge simulation method for the calculation of the capacitance. Finally, the capacitance of the system of the hollow medal cylinder to the perfect infinite metallic ground, finally give and analyze the curves of the capacitance with three parameters are calculateel.
