非平行板电容器电容计算的修正

Calculation of the capacitance for a non- parallel plate capacitor

在计算非平行板电容器的电场和电容时,以往文献大多忽略分布在电容器外部的电荷.本文将电容器外部电荷纳入计算过程,用三种方法得到更加准确的非平行板电容器电容,较其他文献新增了修正项.

Previously,most of the literatures have ignored the external electric field of capacitor in the calculation of non -parallel plate capacitor and capacitor electric field. In the present work, we investigate the external electric field of capacitor and apply three methods to get more accurate results with correction term.
