| 摘 要： | 本文利用小波包将信号按任意时频分辨率（满足测不准原则）分解到不同频段的特点，论述了小波包特征提取的方法。利用这一特性对柴油机气门间隙和漏气故障进行了诊断，取得了满意的结果。

| Abstract: | This paper uses wavelet packet to decompose signals to various frequency bands (uncertainty principle satisfied), describes the wavelet packet signal extracting algorithm. An example in diesel valve fault diagnosis (valve clearance and valve leakage) has shown that this method can be used in fault diagnosis. |
