摘　　要：一些电路教材对二端口网络的连接方式进行了介绍并给出复合二端口参数矩阵的计算方法。多个二端口的任意连接可以构成复合多端口网络,其参数矩阵也可以由构成它的二端口网络的参数矩阵表示。本文类比了电路网络中的关联矩阵,建立描述二端口和复合多端口关系的端口关联矩阵,并利用二端口的特性和串并联的特点,给出了求解复合多端口网络参数矩阵的新方法。The connections of two-port networks and the method to calculate complex two-port parameter matrix are introduced in relevant textbooks.The complex multi-port network can consist of many two-port networks and its parameter matrix can also be made up of the parameter matrix of those two-port networks.In this paper we found the incidence matrix which illustrates the relations between two-port networks and multi-port networks on the analogy of the relative matrix in the theories of electric circuit.And we work out the new way to calculate the parameter matrix of complex multi-port network by means of the characteristic of two-port networks and their series-parallel connections.
