地震

He developed an armillary sphere, on which were carved all the astronomical phenomena known at that time.

张衡认为地震是一种自然灾害，他根据自己对于地震现象的观测，在西元132年发明了『候风地动仪』，这台仪器成为世界上第一台观测地震方向的仪器。

The geologic record indicates that a catastrophic quakehits Cascadia only about every 500 years, but the cities of the PacificNorthwest, like Seattle and Vancouver, are far less prepared than SanFrancisco and Los Angeles for a major earthquake, so when the nextpowerful temblor comes around, the region could suffer.

地质记录表明这里每500年才会发生毁灭性的地震。西北太平洋沿岸的城市，如西雅图和温哥华，都不像旧金山和洛杉矶那样对地震准备充足，所以下一次爆发大地震时，这一块地区很可能受灾严重。

Based on the pre-research of Reservior-Induced Seimicity, the text analyzed water's load effect, interstitial water pressure and chemicophysical effect on rock in Reservior-Induced Seimicity and discussed hydrogeological mechanism of Reservior-Induced Seimicity. The analysis supplys reliance for the hydrogeological analysis of Reservior-Induced Seimicity.

本文在总结水库诱发地震前人研究成果的基础上，系统分析了库水在水库诱发地震中的荷载效应，空隙水压力效应和对岩体的物理化学作用，从理论上讨论了水库诱发地震的水文地质机理，为水库诱发地震的水文地质分析提供依据。

In addition, coseismic Coulomb stress changes also have great influence on aftershocks distribution.

同时，由于鲜水断裂带不同断裂间的相互作用，发生地震的断裂在其相邻的断裂上产生同震库仑应力增加，使下次地震发生于其相邻的断裂上，这也可能是鲜水河断裂带地震沿带南北迁移的重要物理机制。

These characteristics are resulted from the interaction of different faults along this seismotectonic belt and the influences of coseismic Coulomb stress changes on active fault seismic potential.

鲜水河断裂带四次时间上连续发生的地震序列中，每一次地震都发生于受其先前发生的地震的影响而产生了同震库仑应力增加的断裂上(0.01～2.55bar)。

All the above researches are very important to the usage of thelaser Doppler technique in seismic prospecting.The laser Doppler frequency shift of scatters and diffract grating was discusstheoretically.

鉴于地震检波器是制约高分辨地震勘探的重要瓶颈，研究应用激光多普勒效应的新型地震检波器是重要工作之一。

The dam area with an epicentral distance of about 258 km was shocked strongly during Wenchuan Earthquake, and the monitoring station on the dam obtained records of the main earthquake.

该坝址距&5·12&汶川大地震震中约258 km，地震发生时坝区有强烈震感，大坝强震监测台阵获得了主震较为详细的地震记录。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
