地震

It is principally due to the transfer of the seismic motion from hard deep soils to soft superficial soils and to effects of seismic energy focalization owing to typical geometrical setting of the deposits.

它主要应归于来自从硬的深层土壤到软的地表土壤地震运动的传递和由于典型的沉淀物的几何定位而造成的地震能量的集中。

Overcoming the inability of Forcing Decoupling method, this paper presents a new method-To-Step-Additional-Stiffness method to calculate the translation-torsion coupling seismic response of tile symmetric structures with asymmetrically viscous dampers.

摘要克服强行解耦法不能求解对称结构由于不对称安装粘滞消能器而产生平扭耦合地震作用的不足，提出了一种求解该种情况下的平扭耦合地震反应的新方法－两步附加刚度法。

The theory of MS technology and the research achievements by forerunners on MS technology are introduced firstly.

论文介绍了微地震监测方法的原理和前人在微地震监测方面所做的工作。

Q: What is the probability that an earthquake is a foreshock to a larger earthquake?

问：一场地震是一场更大地震前震的概率有多大？

In California, that probability is about 6%. This means that there is about a 94% chance that any earthquake will NOT be a foreshock.

这意味着有大约94%的机会，一次地震不会成为另一场更大地震的前震。

At this time, we cannot tell whether or not an earthquake is a foreshock until something larger happens after it... so only in retrospect.

就目前来说，我们只能根据地震之后是否有更大地震发生来确定它是否是前震。

The Menglian earthquake, a foreshock mainshock aftershock sequence, occerred in 21°59′N; 99°04′E at 05∶46′41 2 on ...

孟连地震是一次前震—主震—余震型地震，发震时刻为1995 年7 月12 日05 时46分41－2 秒；震中为北纬22－0°、东经99－3°。

On 4 February 1975 (during the relative foreshock quiescence), Zhu of the provincial Earthquake Office in Shenyang, when answering the phone and listening to reports,"estimated that a large earthquake might occur."

下午2：40时∶在鞍山地震办公室的日志中有一个记录〔6-5〕∶1975年2月4日下午2：40〔前震活动相对平静期间〕，在沈阳的辽宁省地震办公室的朱〔凤鸣〕，在回答电话和听取报告时，"估计一个强震可能发生"。

Because the quakes did happen one after another, earthquakes are on people's mind, Frankel explained.

因为地震接二连发生，地震也因此引起人们的注意。Frankel解释说。

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。
