变分法在电容的近似计算中的应用

CALCULATION OF APPROXIMATE VALUSE OF ELECTRIC CAPACITY BY THE VARIATIONAL PRINCIPLE

本文应用变分原理,导出了电容器的电容准确值上、下界的计算方法,给出了用此法计算电容器电容的实例,

In this papar, a simple and convenient method of calculating the values of the upper and the lower limits of the electric capacity of a capacitor by using the variational principle is introduced. The lectric capacity of the un—parallel—plate capacitor is calaculated with this method.
