摘　　要：电路领域存在的稳定性问题是在没有激励源的情况下,网络内部必须遵守功率平衡.用微分方程求响应波形.相反的命题是在有外激励源的情况下,已知端口变量的响应波形为正弦,求网络内部功率的盈亏.并用功率的盈亏判定网络的稳定性.The existent stability problem in the circuit domain is that the power balance in network must be keep , when there is no excited source . The response waveform is found by differential equation. The opposite proposition is to find the profit and loss of the power within the network, under that the response waveform of the port variable is the sine and there is excited source. And the network stability is judged by the profit and loss of the power.
