摘　　要：本文讨论了含源T形电路和含源Π形电路的等效变换,扩展了T形电路和Π形电路等效变换的内容。根据含独立电源二端口网络的特性方程,推导了含源T形电路和含源Π形电路等效变换的条件。含源T形电路和含源Π形电路等效变换的结果不具有唯一性,但可通过附加一些条件使变换结果唯一,本文给出了这些附加条件。并通过实例说明了推导结果的正确性。本文的分析对电路教学具有一定的价值,可供教学参考。Equivalent transforms of T and Ⅱ circuits with independent sources are discussed to expand equivalent transforms of T and Ⅱ circuits without independent sources. The conditions of equivalent transforms are deduced according to the characteristic equations of two-port networks with independent sources. Generally, no uniqueness exists for equivalent transforms between T and Ⅱ circuits with independent sources. By adding auxiliary conditions uniqueness can be guaranteed for the equivalent transforms and the auxiliary conditions are given. Examples are shown to prove the correctness of the equations deduced. It is helpful for the teaching of circuits.
