共接收点倾斜叠加波动方程偏移，本质上是一种叠前偏移方法。
Wave equation migration after common receiving point slant stacks (WEMCRPSS) is essentially a prestack migration method.
近些年出现了旨在提高叠前偏移计算效率的多种非共炮记录的偏移方法。
In recent years, people have developed several migration techniques which don't use common-shot records in order to improve computational efficiency for pre-stack migration.
试验结果表明，随着应力波数量的增加，叠前偏移剖面能够反映的缺陷区域更广，成像更加清晰。
Results show that with the increase of the number of stress wave, the clear imaging region became broader and the image of the defect became clearer.
共炮记录叠前偏移对输入的速度非常敏感，要求偏移中所使用的延拓公式能较为精确地适应速度的纵横向变化。
Prestack migration of common shot records is very sensitive to the velocity input, and demands a kind of continuation formula which can adapt to both vertical and lateral velocity variations.
