摘要/Abstract

摘要： 对由自感电动势、互感电动势建立微分方程的方法与由主磁通φ建立电压平衡方程和磁势平衡方程的方法作了联系和对照，结果完全一致。因而用自感电动势、互感电动势建立微分方程的方法既可以讨论含铁芯变压器，亦可用于对空芯变压界的探讨，因此是一个最基本的分析方法。

Abstract:

The method of establishing differential equations with self-induction and mutual-induction electromotive force and the method of establishing voltage-equilibrium equation and magnetic-potential equation with magnetic flux are related and compared in this paper. The consistent results indicate that the former method can be used to study not only iron-core transformer，but also non-core transformer, and therefore, is a basic analytical method.
