摘　　要：文中提出了模拟电路的类故障诊断理论和方法。用k元素(指支路、节点或割集)集间的一种等价关系,对电路中的k元素集进行分类,检验每个类中任一k元素集的相容性,即可辨识出故障类。这种方法诊断目标大,试验后计算量小, 无任何约束条件, 能够处理大规模电路,具有很强的一般性和通用性,对任何电路都可实现故障类的快速在线唯一诊断。The class-fault diagnosis theory and method of analog circuits are proposed. The given approach classifies k-element sets (the element represents the branch, node or cut) by the equivalence relation before test and identifies the faulty class by verifying the consistency of any one of k-element sets in each class after test. The techniqus has very small after-test computation and no restrict on the circuit configuration, applies to nonlinear circuits and large-scale circuits, and diagnoses the faulty class on line uniquely and rapidly for any circuits of any topological structure.
