在确定震源的位置、发震时刻和震源强度之前必须进行滤波处理。
It is necessary to carry out filtering before we determine the position of seismic source, and the exciting time, and strength of seismic signal.
测点上某一震相的振幅和周期决定于震源强度以及震源到测点的整个传播过程中介质对震波的影响。
The amplitude and period of a phase at a receiving point depend on source strength and the effect of medium on seismic wave in the propagating from source to the receiving point.
它同时还可以消除数据采集时由于震源的误差(如震源强度误差、震源取向误差等)所带来的影响。
It also favours eliminating the negative influence caused by source errors such as source strength error, source orientation error and so on in seismic data acquisition.
