time migration meaning in English
时间偏移
Examples
- Prestack migration is performed by reverse - time migration method based on maxwell ' s equations using time - domain finite - difference method
叠前偏移用时间域有限差分求解麦克斯韦方程组的逆时偏移方法实现。 - Compared to poststack time migration , prestack time migration results in clear images of fractures and cavities in the ordovician carbonate rocks , and definite unconformities at top of the ordovician
叠前时间偏移与叠后时间偏移结果相比，具有丰富的奥陶系碳酸盐岩裂缝溶孔内幕，清晰的奥陶系顶不整合面。 - As mentioned above , the easiest run time migration approach is to make community edition and websphere application server co - exist on the same hardware until the development and the test teams are comfortable with the new systems to which they are migrating
正如前面所提到的，最简单的运行时迁移方法是community edition和websphere application server共存于相同的硬件之上，直到开发和测试团队熟悉了他们正在迁移的新系统为止。 - Compared with the conventional finite - difference method on the fixed grid - size rectangular grids , the new method can be more cost - effective in complex models . numerical tests for both seismic modeling and reverse - time migration are performed on various theoretical models and a physical experiment
用该剖分方法得到的网格在各速度层内的空间步长是不同的，而全区域上的时间步长却近于恒定，因此在复杂模型上，本文方法的计算效率要高于传统的矩形网格差分方法。
