已知一个二维数据，y=f(x), 想使得这个数据绕y轴旋转而成为一个旋转对称的三维数据(A two-dimensional data is known, y=f (x), to make the data around the Y axis and become a rotationally symmetric 3D data)

1. 构造含噪音的振动信号 faultysignal_with_noise， 2. 利用小波变换 Wavelet transform去噪，小波包 Wavelet packet transform 变换去噪， 3. 把两种去噪后的信号，分别用STFT ,FFT ,小波变换三种方法进行错误诊断(1. the vibration signal faultysignal_with_noise, which contains noise, is constructed. 2. using wavelet transform Wavelet transform denoising, wavelet packet Wavelet packet transform transform de-noising, 3. the two kinds of denoising signals are diagnosed by three methods, STFT, FFT and wavelet transform respectively.)
