震源

Along with the increasing density of digital seismologic observation network and the developing quality of seismographs, the theoretical and practical exploration of stress changes from seismic data has been the focus of recent debate within the seismological community.

随着数字地震观测台网的普及和数字地震仪性能的提高，用地震观测资料进行震源区应力变化和破裂过程的研究已成为国际地震学界的研究热点。

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。

In this paper,we have discussed the seismotectonic environment that located at the depth and shallow crust and seismology and geology model caused 1927 Gulang earthquake.

通过近年来对古浪8级大震的震源机制解、震区活动构造、地震活动性及深部地球物理资料的研究，进一步探讨了古浪大震孕育和发生的深、浅部地质构造环境和地震地质模型。

At least, three types of earthquake related fault rocks including pseudotachylyte formed by typical fast fault movement, no orientated ultra-cataclasite or sinter breccias may formed by weak earthquake faulting, and stockwork microbreccias formed by autochthonous powerful shock at the source are discovered, in which some of the original sources parameters are remained.

至少区分出三种地震断层产物和两种震源破裂方式：典型快速地震断层形成的假玄武玻璃；或许与弱震有关的无组构超碎裂岩或熔结角砾岩，以及强烈原地震动成因的网脉状微角砾岩。

The operation procedure of borehole and surface combined method was as follows: the instrument was fixed at a certain depth of the borehole section, then the seismic source was moved in designed shooting direction.data were recorded synchronistically on surface and in downhole.

井地联合地震勘探方法是，井下仪器固定于观测井段某一深度，震源在地面按设计的炮线移动，同一炮激发，在地面地震接收的同时，在VSP井中也接收」。

To better understand the regional tectonics, we have inverted local and teleseismic broadband waveform data to determine the focal mechanism of this earthquake.

为了更好的认识区域构造，我们利用近震及远震波形反演的方法得到了此次文安地震的震源机制。

Up to now, all of the methods of isolating the receiver function from teleseismic P waves are based on the data recorded at a single station.

迄今为止，广泛应用的分离接收函数方法主要基于单个台站的观测数据，并依赖等效震源假定的有效性。

In chapter 1,we used broadband teleseismic data of ChingFeng station to calculate the Receiver Functions,then obtained a velocity model with H-K stacking method in combination with Crust2.0 and other previous work.

在本文的第一、二章中我们回顾了震源参数反演方法的发展，并详细介绍了几种主要的反演方法。

Tests of record type,source duration,attenuation factors of P and S body waves are made for sensitivity study of moment magnitude.After weighting regional data and teleseismic data properly according to their amplitudes,they can be used together in a Cut and Past inversion process.

本文第四章中我们对新近发展的CAPloc方法进行了一系列的测试，即在稀疏台网的条件下得到地震的震源机制解，并将其与利用整个TriNet数据反演得到的机制解进行对比，分析了单台和双台反演的稳定行和可靠性。

Clearly identifiable depth phases recorded by the teleseismic stations obviously provided a better constraint on the resulting source depth.

随后结合远震信号中的直达P、pP、sP波形得到了分辨率较高的地震震源深度。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
