| 摘 要： | 本文证明了一个适用于线性含独立源网络的结论：当某支路阻抗变化之前，该支路的电流已知或容易求出时，在这个阻抗变化后能够很容易地求出该支路的电流增量或者电压增量，以及其它支路的电流增量或电压增量。利用此结论可以进一步求出对应支路新的响应或进行灵敏度分析。本文给出了一些实例并讨论了这个结论的应用。

| Abstract: | A conclusion is proposed and proved which can be used in linear network of independent source. When the branch current is known and can be found before the change of the branch impedance, the current increment or voltage increment in the branch or other branch can be easily found using this conclusion after the change of the branch impedance. Thus the new response of the corresponding branch and the sensitivity analysis of the branch can also be obtained. Some examples are given to illustrate the use of the conclusion and the applications of the conclusion are discussed. |
