1. The first offshore multiwave and multicomponent seismic experiment has been made by CNOOC.
   中国海洋石油领域开展了首次海上多波多分量地震试验。
2. The theoretical seismicwavelet clearly indicates the characteristics of real seismic wavelets in seismic ex-ploration to thus improve geop...
   该成果不仅对地震勘探有实用价值，而且对处理其它形式的瞬时震源问题也有一定的理论意义。
3. Many uncertain factors are involved in seismic performance evaluation and the probabilistic results drawn from inadequate information are suspectable.
   结构的抗震性能评估中包含许多不确定性因素。
4. In seismic exploration, using SEG-D format is convenient and flexible, but this flexibility brings difficult in common use of demultiplex modular.
   在地震勘探中,SEG-D格式使用方便、灵活,但其灵活却为解编模块的通用带来较大的困难。
5. The spatial variation of seismic ground motions is produced primaryly by the three factors of geometric incoherency effect,wave-passage effect, and local site effect.
   导致地震动空间变异性的原因主要在于:几何不相关性效应、行波效应、局部场地条件效应。
6. The drilling results and drill stem test result prove that the prediction results of seismic nonelastic effect completely coincide with the actual gas-bearing Situation in the reservoir.
   钻井结果和中途测试结果证实，地震非弹性效应预测结果完全符合地下储层含气性实际情况。
7. The shift, collision and within plate intraformational gliding of plates may result in the occurrence of earthquakes.Two seismic zones may be recognized in China: eastern and western seismic zones.
   板块的移动、碰撞和板内层间滑导致了地震，中国境内可以划分两个地震带。
