The spectralcomponent of foundation motion is changed, and the motion of foundation is smaller than that of free field.
相互作用改变了基底地震动的频谱组成，使基础处的地震动比自由场地震动小。

During the acoustic logging data process, the information of time-frequency of related spectralcomponent can not be provided generally by means of Fourier Transformation (FT).
在声波测井资料处理的过程中，傅里叶变换通常不能提供有关谱分量的时间局域化的信息。

Experimental comparisons show that the method proposed is better than traditional IHS and wavelet transform fusion method in preserving spatial resolution and spectralcomponent.
