计算机实现有源网络全符号函数的一种方法

本文定义一种三维字符数组,用数组的第三维存放节点电导方程中元素的字符表达式,根据电网络的输入信息,自动列出节点电导方程.按照作者1982年一文提出的求Coates图的1-因子定理,给出方程的全符号函数解.此法与其他有源网络的拓扑分析法比较,如Mason图的方法,有不少优点,具有实用价值.

An Approach to the Genera tion of Active Network Symbolic Function

In this paper, an array called three dimension character array is defi-ned. The character expression of nodal admittance equation's element is placed in the third dimension. According to the input imformation of netwerk, the nodal admittance equation is obtained. According to author's theorem to generate all the 1-factors of Coates graph, a solution with symbolic func-tion expression to the equation is given. It is shown that the computer program based on Coates's formula is more efficient than the one based on Mason's formula.
