摘要
本文提出了网络矩阵的Ｈ的一般Ｋ阶余因式Ｈ〔＾ｉｊ］的拓扑分解原理和公式。应用它们求全符号网络函数，采用向下分解向上组合法可明显扩大计算机所能拓扑分析的电网络规模，更容易在计算机上实现。应用它们求部分符号网络函数，很好地解决了拓扑法和数值法的结合问题，可使计算机所能分析的电网络规模扩大到一般数值分析程序所能处理的阶数。
In this paper, topological decomposition principles and formulas for general k-order co- facto H(?) of network matrix H arc presented. Using these methods, the all-symbolio network func- tions can be found. The scale of electrical network which can be topological analysed by a computer will be increased obviously by mouns of doown-decomposition up, combination method. They are moe easily operated with a computer. Using these methods, the part-symbolio networkfunctions can be found. The problem of combination of topological method and numberical method can be solved bet- ter. The electrical network scale which can be analysed by a computer is expanded to the network size which can be analysed by the general numberical analytical progam.
