stack press
解釋
堆層壓機-
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。
