摘要
对于非平行平板的电容器，构造一个势函数，求电场和能量，经过对能量求极小值得到能量的近似解，进而得到电容的近似解．
For a capacitor decilining tablet, a solution about the electric field and its energe was obtained by making a potential function. The result shows that the approximate values about the energe and the capacitor can be obtained by making minimun values.
