摘要
为了在F(z)上分析网络的结构性质,有必要分析网络状态方程系数矩阵A的特征根.在多元有理函数域F(z)上,A的特征根可能是"0"或者不相等的非常数根.根据电网络理论,若网络中含全电容割集和全电感回路结构,A将有"0"根,它对应于F(z)上的"0"根.在网络结构上,部分"0"根对应于全电容割集.对于一个任意的网络,详细讨论了利用计算机来查找电网络中"独立"的全电容割集这一类特殊结构的算法,并通过实例介绍了分析步骤.
In order to study the structural properties of electrical network over F(z), it is necessary to analyze the coefficient matrix A of the state equations . In previous paper, author has proved that the characteristic roots of A are zeros or unequal non-constants. According to electrical theory, all-capaci- tor cut-set and all-inductor loop would cause zero eigenvalue. Author expatiates an algorithm on how to find the independent all-capacitor cut-set in electrical netwok with computer and uses an example to show the process.
