velocity analysis

Since general velocity analysis often ignores the quartic item of equation, time difference should be corrected for the data of the far offset distance, and its velocity analysis error influences the stacking quality of data.

由于常规速度分析一般忽略计算公式中的四次项，因此，对于较大偏移距的资料就存在校正时差的问题，其速度分析误差影响了资料的叠加质量。
