说明：  小波包分析提取振动信号中的特征频率，分析了该信号的时域、频域、倒谱，循环谱等,有井曲线作为输入可计算其地震波的衰减。
( Wavelet packet analysis to extract vibration signal characteristic frequency, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. There is a well attenuation curve as input to calculate its seismic waves.)
