摘要
用节点法论证了由正的电阻、电容、电感及具有正定电感矩阵的耦合电感和独立电源组成的线性时不变网络唯一解存在的充要条件．
Both necessary and sufficient conditions for the unique solvability of linear time invariant networks are discussed. The networks are composed of positive resistors, capacitors, inductors, coupled inductors with positively definite inductance matrix and independent power supply.
