地震学的

In addition, after comparing the time difference between the precursor and the main PKKPbc phase at different outer core conversion point positions, we find the seismic evidence for the tangent cylinder structure in the outer core.

4通过对PKKPbc波形及其前驱波的分析，得到了外核顶部轻元素组成的刚性薄层的地震学性质：我们还通过比较不同位置的前驱波到时的差异，提出了外核可能存在tangent cylinder结构的地震学证据。

It is the bridge of linking engineering seismology and theory of building.

它是联系地震学、地震工程学和建筑结构课程知识的纽带。

Historical seismology is a new developing subject.

摘要 历史地震学是一门新兴的学科。

We concentrate on two areas: continuum mechanics and earthquake seismology.

我们的关注点是连续介质力学和天然地震学。

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。

IsraelNN.com The Seismologic Division of the Ministry of National Infrastructure's Geophysical Institute will attempt to simulate an earthquake in the southern Negev on Thursday. The experiment, financed by the U.S. Defense Department, is a joint project with the University of Hawaii and is part of a scientific project intended to improve seismological and acoustic readings in Israel and its environs, up to a 1,000 km/621 mile radius.

IsraelNN.com）国家基础设施部的地球物理研究所的地震学小组，周四在内盖夫南部将尝试模拟地震，是经费由美国国防部支持的实验，与夏威夷大学的一个联合项目，亦是一一个科学项目的部分，旨在改进地震学和在以色列和其周围地区的声学读数，达到 1000 km/621哩半径。

Strain rate components are computed in spheric coordinate system. Analyses of the spatial distribution of strain rate fields derived from GPS measurements are carried out in contrast with seismological and geological results.

在球坐标系中解算了各应变率分量，分析了应变率场的空间分布特征，并与地震学和地质学研究结果进行了综合对比分析。

In this paper, some methods of fuzzy mathematics suah as the direct method of fuzzy pattern recognition, the method of fuzzy clustering analysis the method of fuzzy information retrieval, and the recently advanced method of fuzzy fractal dimension have been applied to earthquake monitoring and prediction in the Surrounding Capital Area based on the seismicity and earthquake precursors. The seismic and unseismic precursors before both the Tangshan M=7.8 great earthquake in July, 1976 and the Datong-yanggao M...

本文把模糊数学中的模糊模式识别的直接方法、模糊聚类分析方法、模糊信息检索方法和新近提出的模糊分维方法应用到以地震活动性和地震前兆为基础的首都圈地震监测预报当中，分析研究了发生在这一地区的两次大地震，即1976年唐山7.8级和1989年大同6.1级地震前用模糊数学方法识别出的地震学前兆和非地震学前兆，并对这一地区大地震的长期和中短期模糊预报方法与途径进行了简要的讨论。

Modern seismologists used the responses to those questionnaires to reconstruct in detail what happened.

现代地震学家用这些问卷结果重现了当时所发生的一切。

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
