摘　　要：比较了基本RS触发器、同步RS触发器、主从RS触发器和主从JK触发器等不同电路结构触发器的动作特点,特别对禁态、不定态、多次翻转、一次变化等理论教材和产品手册中论述不多,却在工程使用中必须考虑的问题进行了讨论.Operating characteristics of RS latch, RS synchronous-triggered flip-flops, RS　edge-triggered flip-flops and JK edge-triggered flip-flops which have different circuit'　constructions are narrated and compared completely. Especially some peculiarities such as　'forbidden state', 'uncertain state', 'repetitious change' and 'one-shot change', which can seldom be founded in teaching materials and manuals but are useful in practice are narrated and illustrated completely.
