从等效观点论证置换定理

THE VERIFICATION OF SUBSTITUTION THEOREM FROM THE VIEW OF EQUIVALENCE

在电路分析中 ,置换定理是一个应用广泛的重要定理 ,该定理在分析复杂电路过程中具有独特的作用 .教材在证明该定理时 ,一般都是从解的存在性与唯一性加以证明 .本文从另一角度 ,利用等效的概念论证了置换定理的正确性 ,论证过程具有简单 ,明了 。

The Substitution theorem is an important theorem widely used for circuits analyses especially for complex circuits. Different than traditional way to verify the theorem from the existence and uniqueness concept successfully, simply and fairly to verify the theorem.
