模拟电路可撕裂的拓朴条件

Topological Condition for Tearing Large Analog Circuits

在模拟电路故障诊断中为了简化运算过程或分离出故障部分，往往需要把一个网络撕裂成几个子网络。但是由于可及点的数目有限及分布的不同，撕裂并不是任意的．本文提出了一个拓朴条件，当这个条件满足时，网络可以在不可及节点上被撕裂成两个可以进行计算的子网络。

In the faulty diagnosis if linear large analog circuits, there are needs to tear a large network into several subnetworks so as to isolate a faulty part and simplify the computation. But a successful tear can not be randomly performed because of the limited number of accessible nodes in a circuit. This paper presents a new topological condition for successfully tearing a network. When the condition is satisfied, the network can be torn two computable sub- networks on some inaccessible nodes.
