说明：  基于小波包变换的人工地震波合成(：以原始地震波为母波，以与抗震规范相容的功率谱为目标谱，利用功率谱与小波包变换系数之间的关系式，提出了利用小波包变换合成人工地震波的新方法)
(Based on wavelet packet transform artificial earthquakes (: to the original wave seismic waves for the mother to seismic code compatible with the power spectrum for the target spectrum, using the power spectral and wavelet packet transform coefficients of the relation between the proposed wavelet packet transform A new synthetic method of artificial seismic waves))
