地震学

Fortunately, the modern geodetic measurements such as the Global Positioning System technique can overcome the shortage of the geological and seismographic methods in the time dimension; and yet, the coverage of the geodetic survey stations is not sufficient. As a result, it is necessary to employ numerical simulation to investigate the continuous deformation of the crust.

而以全球定位系统等技术为主的大地测量方法弥补了地质和地震学方法在时间维上的不足，但大地测量方法存在测点覆盖不足及测点地理分布不均匀的缺点，因此，要得到连续的地壳形变场有必要借助数值模拟方法。

Experts have said that there are no recorded cases of a natural earthquake causing a mine collapse in Utah, and that seismographic data is more consis-tent "with the collapse being the cause of the 'earthquake' rather than the other way around".

拒专家们介绍，到目前为止，尤他州还没有关于地震导致煤矿坍塌的记录，而地震学数据更支持坍塌是引起地震的原因，而不是相反。

First field relates to the studyearth's interior by using seismic waves,such as the development of seismographic techniques,digitalseismology,seismic tomography,seismic exploration and the detection of undergroud nuclear explosions.

简要回顾了当代地震学发展的两个方面，一是利用地震波探测地球内部。

May or not be quake is occur with look up see chandelier to know". Because of a lofty overhang chandelier very sensitive to ground plane motion and it is shaking repeatedly by action of inertia force during a quake happen. In 19 century, a" zhong you du zhu "of ancient Chinese seismographic phrase was translated "one stick in the middle and it is hanged by the ancestor Ernt of modern seismology .

地震没地震，抬头看吊灯&，就是因为高高悬垂的吊灯对地面的水平运动非常敏感，会因惯性不停摇摆。19世纪，现代地震学鼻祖米尔恩把&中有都柱&译成&中间有一根柱子，这根柱子是悬挂起来的。

Meanwhile,the rate of accumulation of broadband digital seismologic observation data is increasing exponentially,meaning that the research on high resolution seismic imaging of earthquake source rupture process and internal structure of the earth will be an important development trend of seismology in the 21st century.

与此同时，宽频带数字地震观测资料的积累速率按指数增长，这意味着震源破裂过程及地球内部结构的高分辨率地震成像研究将成为21世纪地震学发展的重要趋势。

The relationship between research on seismology and on dynamics of the earth will be closer and closer with each passing day,the role and importance of broadband mobile seismologic observation will certainly grow day by day.

地震学与地球动力学研究的关系将日趋紧密，宽频带流动地震观测的作用和重要性必将与日俱增。

For further analysis of seismological interest, specific symmetries of the media need to be considered.

为了进一步分析在地震学方面具有重要意义的问题，必须考虑介质的特定对称性。

Such a research strategy does not conflict with the ethics of seismological study.

这样一种研究战略在地震学研究中并不与道德规范形成矛盾。

Within the distance of 200 km from the epicenter, there were 29 seismic stations. Among them, there were 10 seismometric stations and 23 precursory observation stations.

在此基础上经重新整理和筛选后，确认本次地震前出现了12个项目共17条异常，其中地震学异常2条，前兆观测异常15条。

First, some seismotectonic belts in southeast and northeast Qinghai-Tibet Plateau which have similar geodynamic background are selected.

本文从地震地质学角度出发，充分利用地震学和岩石力学等学科中的相关研究理论和方法，将地震活动与具体的地震构造相结合，探讨了包含多个孕震区或断裂带的大陆板内地区的地震复发规律，提出了大陆板内地震的准周期丛集复发模式，并系统、全面的研究和讨论了不同断裂之间的相互作用及其对活动断裂地震危险性的影响，从机理上揭示了大陆板内地震准周期丛集复发行为的内在物理基础。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
