摘要： 提出了一种灵敏度序列字典法,可快速定位级联线性电路中单级子电路的故障,不管这个故障是何种性质(硬、软、单、多);提出了逐级搜索法,可定位两级以上子电路同时发生的故障,不管这些故障是何种性质.这种软、硬故障统一诊断字典法的继续和发展,使字典法成功地从"元件级"诊断进入了"子电路级"诊断.

Abstract: In this paper,a dictionary approach for fault location in cascade linear circuits is presented. The approach can locate any sub -circuits which have any faults (soft or hard, one or more than one). Because "cascade" is the universal joint way among sub-circuits of linear circuits, the approach is practical and usefull.

Key words: dictionary approach, fault location, cascade circuits
