In migration processing, we usually require that migration datum is horizontal and that zero point for migration should be on the ground surface on which shot point and receiving points lie.

在作偏移处理时，一般要求偏移基准面是水平的，且偏移的零点应在激发和接收的地表。

In this paper, the way of constructing the common shot-point synthetic seismogram and the zero-offset synthetic seismogram by finite element method was examined.

本文对用有限单元法制作共炮点合成地震记录和零炮检距合成地震记录的方法进行了研究。

This results in around 500 megabytes of data per shot point.
