This can increase efficiently the signal - noise ratio of seismic record, under the general situation, the signal - noise ratio of big scale is small, because low frequency surface wave in big scale is more serious, the correlate of signal is smaller, so weighting stack can press efficiently low frequency surface wave, comparative promote the percentage of the effectual signal in constructing the signal
這樣可以有效地提高重構后地震剖面的信噪比，一般情況下，大尺度的信噪比都較低，因為大尺度內的低頻面波比較嚴重，信號相關性較小，這樣做加權可以有效地壓制低頻面波，相對地提升有效信號在重構信號中的百分比。 -

It is shown by the two - stories frame model shake - table test that the contrast two response of acceleration based on wavelet and experiment draws on such conclusion : littlewood - paley wavelet does not agree with the test, so it is not suitable for structural seismic response, because structural acceleration response is too small. the wavelet transform result of acceleration response based on meyer wavelet, harmonic wavelet and odd exponent wavelet agree with the test, thus they can be used to analyze structural seismic response. the analysis of earthquake ground motion energy and structural energy response based on these three wavelets ( littlewood - paley wavelet, meyer wavelet, harmonic wavelet ) shows that we can calculate earthquake ground motion energy by the record of acceleration, because the wavelet coefficient includes time - domain energy and frequency - domain energy
