讨论了一种对回转机械中具有多种倍频故障的全息谱进行分解得到多个只含单一故障的全息谱的方法，该方法有助于判明各倍频故障的存在及严重程度，为回转机械的检修提供参考
A method of decomposing the holographic spectrum with multiple frequency-doubling faults in rotary machinery to obtain multiple holographic spectra with single faults is discussed. The method is helpful to identify the existence and severity of each frequency-doubling fault, Mechanical maintenance for reference
