【摘要】 首先利用零泛器将适于无源网络的故障诊断方程推广至适用于含有四种受控源电路的有源网络．然后，从拓扑上讨论了故障有源网络的局部可测性条件和全局可测性条件．最后给出一个可测性分析的例子．更多还原

【Abstract】 With the aid of nullor, the fault diagnosis equations for passive networks are extended to the case of active networks with four controlled sources. Then conditions of local testability and global testability for faulty active networks are topologically discussed. An example of testability analysis is given at the end of the paper.更多还原
