stacking velocity

This paper deals with two problems, nonzero-offset Fresnel zone in homogeneous media, and the effect of velocity error resulted in NMO correction and stacking on vertical resolution.

本文讨论了均匀介质情况下非零炮检距菲涅耳带和动校、叠加中速度误差对纵向分辨率的影响这两个问题。

The method of employing DIX formula to get interval velocity from the spectrum of horizontally stacking velocity is only applicable to hori-zontal layered-medium.

根据水平迭加速度谱用DIX公式求取层速度的方法，只适用水平层状介质。

Reference [ 1] and [ 2] suggest an approach of minimum span tree for automatic pick of the stacking velocity.

在文献[1][2]中，曾先后提出过利用图的最小生成树的模型和方法自动拾取叠加速度，并取得了一定的效果。

At the same time, the interval velocity derived from the time_ shift_corrected spectrum τ 0 is more accurate than that derived from the traditional Dix_equation_calculated stacking.

同时，用时移动校正τ0分析谱计算层速度较以往用Dix公式由叠加速度计算层速度精度要高。

The usual method for obtaining interval velocity is to derive stacking velocity from velocity spectrum, then to calculate interval velocity by Dix formula.

目前普遍采用的方生是由速度谱先求取叠加速度，然后再用Dix公式求取层速度；
