说明：  第八章 共反射面叠加 在常规处理中，时间域成像和叠后偏移的效果不是很理想，对复杂构造的成像更是如此。于是一些新的时间域成像技术和叠前偏移方法应运而生，共反射面（CRS）叠加便是其中的一种。CRS叠加是一种不依赖于速度信息，可以直接由多次覆盖反射数据得到零炮检距（ZO）剖面的叠加成像技术。
(The eighth chapter common surface stack In conventional processing, the effect of time domain imaging and post stack migration is not ideal, especially for complex structures. As a result, some new time-domain imaging techniques and prestack migration methods emerge as the times require, and common reflector (CRS) stacking is one of them. CRS stacking is a kind of superposition imaging technology which does not depend on velocity information and can directly obtain zero offset (ZO) profile from multiple coverage reflection data)
