The signals that indicate the faults of i . c . e . are usually being concealed by the normal working signal . the key work of condition monitoring and fault diagnosis should be finding out the fault feature parameters from disorder working signals 其内部的故障信号往往被淹没在正常的工作信号中而难以发现，所以，如何在杂乱的工作信号中提取表征故障的特征参数，是状态监测与故障诊断的关键所在。
