基于叠加定理导出的比值恒定定理及应用计算

基于叠加定理的思想,本文提出了一个新的用于计算线性电路的方法.该方法利用指出在多电源线性电路中,各电源在任一支路产生的电流之比为一定值,即比值与该支路的无源线性元件无关,且等于将该支路的无源线性元件短路后,每个电源分别在此产生的电流之比.据此,可使一些复杂电路分析计算变得简单明了.

Ratio Invariableness Theorem and Its Applications Based on Superposition Theorem

By the thought of Superposition Theorem,A new way to analyze linear circuit is presented. In any linear circuit of no less than 2 sources, the current ratio which is produced by every source in any branch is invariable. Ratio Invariableness means that it is independent of Passive Components in the branch, and the ratio is equal to the Short Circuit current which every source produces when the passive component is shorted. Therefore, the way can be used to analyze some problems more simpleness and easiness than other theorems sometimes.
