- ：提出一种基于对偶树复小波块阈值的信号降噪方法，并将其成功应用于机械故障诊断中。机械设备的振动信号都或多或少地含有噪声，导致弱故障信息的提取一直是故障诊断的难点和热点。提出的降噪方法充分利用对偶树复小波变换的平移不变性和块阈值法的更优估计特性，可以获得比常规的小波降噪方法以及基于常规离散正交小波变换的 NeighBlock 降噪法更高的信噪比， 不仅能有效抑制高斯白噪声， 还能够去除冲击信号中的脉冲噪声。-：A denoising method of block thresholding bas

- 在小波的分解过程中，每一次的小波分解得到的近似信号会比上一层次的信号更加光滑，而被抑制的细节系数则存在于每一层中。所以可以将一个含噪信号进行第5层分解，并有选择的抑制部分细节系数就可以达到信号降噪的目的。试验中采用‘db4’小波对信号进行分解。-In the process of wavelet decomposition, every wavelet decomposition to get the approximate signals will be more smooth than on
