摘　　要：分析了故障字典法在实际应用中存在的不足 ,提出将单位 BP算法应用到电子线路的故障诊断中。对基于该方法的航空装备电子线路故障诊断进行了计算机仿真 ,并分析了网络参数的变化对训练结果的影响。The defects of the fault dictionary method in the practical application are analyzed and the application method of an unit BP algorithm which is used in the fault diagnosis of the electronic circuit is put forward. This paper validates the diagnostic technique with the example of some electronic circuit of the aero electronic equipment by computer simulation and evaluates the diagnosis results with different neural network structures and different parameters. Simulation results indicate the rationality and validity of the method.
