方法比其它诊断方法，如振动法、性能参数法等能更加早期地预报机器的异常状态，证明了这种方法在应用上的优越性。因此尽管这种方法出现较晚，但发展非常迅速，应用范围日益扩大，已成为机械故障诊断技术中举足轻重的方法了

Compared with other diagnostic methods, such as vibration method and performance parameter method, this method can predict the abnormal state of machine more early, which proves its superiority in acangzhou.89ix.comshiyanjiw.89ix.comshoubanhulu.07858.netdianbiaox.37ix.com.cnzengbaiji.37ix.com.cny
