摘　　要：为帮助学生理解和应用互易定理,从纯线性电阻二端口网络的T型或Π型等效电路和定理的4种端口形式出发,指出理解电路互易和翻转后不同二端口电路在同一激励下的响应相等是掌握互易定理内涵的关键;提出"互易定理口诀",以便于采用互易定理分析实际电路.To help the students have a better understand and usage of reciprocity theorem,in this paper,we propose a reciprocity theorem table. Based on the four forms of the ports at reciprocity theorem and the equivalent circuit of two port network with pure linear resistance,we study the reciprocity theorem. It has been shown the instinct property of the theorem is the equivalent response between the reciprocity circuit and the reciprocal circuit.
