中文摘要:
      应用能量分析法来计算两导体间的电容.双能量法是把整个电磁装置看作一个系统,从 系统处于平衡时的能量有极大值或极小值出发.从而获得系统简单近似的能量分布.这种近似提 供了计算电容准确值的上界和下界值.
英文摘要:
      The dual energy method is a way of treating the energy of the whole device as a system. By noticing that the system energy at equilibrium has a maximum or a minimum va1- ue, it can obtain relatively simple approximations to the energy distribution. These approx- imations provide both the upper and the lower bounds of the accurate values in calculating the capacitances. The calculative method is simple, the accuracy is high, and so a great amount of calculative labour and expenses can be saved.
