stacking velocity

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.

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；

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。
