说明: 小波(Wavelet)这一术语,顾名思义,“小波”就是小的波形。所谓“小”是指它具有衰减性;而称之为“波”则是指它的波动性,其振幅正负相间的震荡形式。与Fourier变换相比,小波变换是时间(空间)频率的局部化分析,它通过伸缩平移运算对信号(函数)逐步进行多尺度细化,最终达到高频处时间细分,低频处频率细分,能自动适应时频信号分析的要求,从而可聚焦到信号的任意细节,解决了Fourier变换的困难问题,成为继Fourier变换以来在科学方法上的重大突破。有人把小波变换称为“数学显微镜”。
这套讲义生动详实的快速带领初学者掌握小波的基本要点,是不可多得的好材料!(This is a handbook about Wavelet.)

循环平稳信号是一类特殊的非平稳信号,其统计特征具有随时间呈周期变化的特点。旋转机械由于周期运行方式其振动信号具有循环平稳特性,因此利用循环平稳分析方法能够提取出在平稳假设下所不能得到的隐藏故障特征信息,为有效地分离和识别旋转机械早期微弱故障特征提供可能。(The cyclostationary signal is a special type of non-stationary signal whose statistical characteristics have a periodic variation with time. Due to the cyclical operation of the rotating machinery, the vibration signal has the characteristics of cyclostationary stability. Therefore, the cyclostationary analysis method can extract the hidden fault feature information that can not be obtained under the stationary assumption, which provides the possibility to effectively separate and identify the early weak fault features of the rotating machinery.)
