提出了不定导纳矩阵的伴随二分图的概念,给出了不定导纳矩阵的一般k阶余因式的拓扑表达式,从而为有源网络提供了一种新的拓扑分析方法——伴随二分图法。
The concept of concomitant bipartite graphs of indefinite admittance matrices is proposed, and the general k-th order cofactor topological expressions of indefinite admittance matrices are given, which provides a new topology analysis method for active networks - Figure method.
