| 摘 要： | 本文主要针对两个主要噪声源，频率相同或相近用谱分析很难区别主次时，采用相干分析法，根据各噪源辐射的噪声能量在总噪声能量中所占比重的大小，来识别噪声源的主次。

| Abstract: | When the frequencies of two noise sources are the same of approximately the same,it isdifficult to discriminate one from the other.On the basis of coherence analysis,the problem is solved bycalculating the proportion of the noise energy emitted from each of the noise source. |
