电容的计算

CALCULATION OF CAPACITANCE

介绍了计算电容的三种方法 :定义计算法、模拟计算法、能量计算法 ,并且用这三种方法计算带缝长直半圆柱面电容器的电容 ,得到了相同的结果 .

The three ways of calculating capacitance -definition calculating, simulation calculating, energy calculation are introduced.By these ways,the authors get the same result about the capacitance of charged long straight semi-cylinder surface capacitor.
