在网络定理中受控源替代的应用

分析讨论了不含受控源网络解的唯一性问题及受控源替代后的情况，得出结论认为：可以用相应的独立源来代替受控源，只要替代后的网络满足元件Ｒ，Ｌ，Ｃ都具有正参数，且Ｍ的电感矩阵是正定的，网络中不含纯电压源回路和纯电流源割集，网络定理就有效；若最后得不出唯一的结果，原因在于网络本身无唯一解

The Application of the Controlled Fountain Used in the Network Theorem

After analyzing the problem of uncontrolled fountain and the substituted controlled fountain, the relative independent fountain can be substituted for the controlled fountain. If the substituted network meets the component R, L, C,it will be the only numerical value and the inductance matrix of M is positive definite .When there is no pure voltage fountain return circuit and pure current fountain cutsets in the network, the network theorem is valid. If the single solution cannot be obtained at the end of using the substitution of controlled fountain, no solution exists in the network itself.
