The method throws away the idea of traditional common mid-poit (CMP) stack and solves at root the difficulty met by traditional seismic processing technology based on CMP method.
该技术抛开了传统共中心点叠加的思想，从根本上解决了以CMP方法为基础的传统地震处理技术遇到的困难。

In order to in-phase stack of aligned reflection events on CMP gathers, the stack velocities may have some higher or lower anomalies.
若使共中心点道集内的反射同相轴校平后能够同相叠加， 叠加速度则会出现一些低或高的异常。

Pre-stack depth migration technique can be realized either in shotpoint receiver domain or in CMP offs et domain.
