在叠前共深度点道集内各地震道的动、静校正误差很小的情况下，地震资料时间域水平叠加方法有较好的叠加结果。
The conventional stack method of seismic data gives quite good results when the errors of time corrections are small enough or the arrivals are near the same.
利用CDP道集，可以直接获得共中心点叠加时间剖面或视深度剖面，由此可转换为法向深度剖面。
By using the CDP gather, common-mid-point stacked time section or apparent depth section can directly be obtained, which can be converted into normal depth section.
