地震

However, source wavelet and near offset traces information will be needed for applying this technique. Energy minimizing method and band-limited parabolic Radon transform is employed to meet the above two conditions.

在逆散射级数法的实现过程中，地震子波和近道波场是必不可少的信息，本文采用能量最低法则和带限抛物Radon变换法来弥补原始地震资料中所缺失的这些信息。

This earthquake is a 7.9, I think they did not expect such a large earthquake to strike and the mountainous terrain of Sichuan made matters worse.

这次地震是7.9级。我认为他们没有想到会有如此厉害的地震发生，而且四川多山的地形也使得情况更加糟糕。

The corresponding aiding province for Beichuan Qiang Nation Municipalism is Shandong Province.

众所周知，尽管北川羌族自治县不是2008年5.12汶川特大地震的震中，但北川是在这次强震中受损的极重灾区，即使远在与江油市接壤的香泉乡，被地震毁坏的房屋也随处可见。

Many people believe that the Nagano Seibu Earthquake was a "dam-caused quake".

许多人都认为长野西部地震是一次"大坝源性地震"。

In the last a few years, the differential solution of wave equation was hold up by the condition of computation. Kirchhoff integral method rose in the initial stages of the ninetieth decade of last century.

前几年波动方程微分解由于受计算条件的限制而难于在地震资料处理过程中发挥作用，上世纪90年代初发展起来的克希霍夫积分方法，因本身存在的缺陷也难于在深层地震资料处理中取得新的突破。

Not only geodetic deformation are in non homogeneity for the space time distribution,but also deformation fields are in macroscopic similarity for the identical time interval.The inherited tectonic movement is a total tendency of recent crustal movement,and the m...

地壳运动过程中存在着区域应变能积累阶段和释放调整阶段，这可能是地震活动的相对平静与活跃的动力机制。1991年以来的地壳运动趋势分析，对判断该区域的应力状态和地震大形势具有一定的参考意义。

Finally, we present an arithmetic of multiplehypocentral, heterogenous dislocation, and a multirupture segment superposition model for simulating the earthquake deformation field. The simulated LOS interferometry map presents the distribution characteristics of the earthquake deformation field better than that of previous studied. Meanwhile, a suit of fault geometric parameters of the earthquake is also obtained by the study. Having a better effect upon simulating asymmetry, great dislocation, macro rupture field, and nonhomogeneity of dislocation than the traditional model, the multisegment method is a progress of this work. It provides a better explanation for the study on hypocentral parameters.

基于上述原因，本文对Okada线弹性位错模型的算法进行了改进，提出了"多震源、非均一位错分量、多破裂段叠加"的线弹性模型，该模型模拟出的形变场干涉纹图较好地体现了地震形变场的分布特征，并由此获得了一套较为完整的地震发震断层的几何学特征参数，为破裂带长度、破裂面方向、破裂面大小等震源破裂特征参数研究提供了较好的解释。

What would have had only minor consequences under normal circumstances led to a chain of events in which 57 people died and thousands of square miles of pristine land ended up devastated.

这个原本在正常情形下只会产生轻微后果的地震，却又引发了一连串地震，导致57人死亡，数千平方英里的土地在灾难中毁灭。

It is found that these earthquakes are concentrated in the meizoseismal area. The direction appears north by west and depth is about 7 km.

结果显示：地震震中集中分布于郭家坝M3.8地震的极震区，方向呈北偏西，震源深度约7km。

In the first case the prediction of earthquakes is a null hypothesis; in the second case the prediction of some earthquakes might be possible.

在头一种情况下，地震的预测是一个无意义的假定；在后一种情况下对某些地震进行预测可能是可能的。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
