查询词典 earthquake

This gives the conclusions that the period and earthquake response show to be small when base buries have 6 meters in difference under the same earthquake wave. The dual tower with base structure can be simplified as a single tower with a base structure to simplify seismic analysis and calculations with small errors, when stiffness of the basement of the dual tower is larger.

得出了如下结论：同一地震波作用下，在基础埋深相差6m左右时，其周期和地震反应相差较少；一个大底盘上双塔楼建筑当底盘刚度较大时，可以将双塔楼带底盘结构简化为单塔楼带底盘结构进行抗震分析计算，误差较小。

Refers to the super-earthquake seismic waves very strong earthquake.

超级地震指的是震波极其强烈的大地震。

At last, three waves of earthquake ground motion are selected as inputs and loading conditions are set out by considering the earthquake environment of Nanjing city.

最后，根据南京及其周边地区的地震环境，对台面输入地震动的选取及其加载方法进行了具体的阐述。

Mr. Emend,the maths teacher from Australia,said that when the earthquake started he thought there was something wrong with him,but then another teacher said that it was an earthquake.

Emend先生，一位来自澳大利亚的数学老师说，当地震发生的时候，他觉得自己有些不太对劲，但是另外一些老师说，地震了。

In order to use structure's ability of elastic-plastic deformation to consume the earthquake energy, decrease the reaction in the earthquake, ferroconcrete frame structure should be designed into ductile one.

为了利用结构的弹塑性变形能力耗散地震能量，减轻地震作用下结构的反应，应将钢筋混凝土框架结构设计成延性框架结构。

In order to use structures ability of elastic-plastic deformation to consume the earthquake energy, decrease the reaction in the earthquake, ferroconcrete frame structure should be designed into ductile one.

本文主要阐述了钢筋混凝土框架结构的耗能机理和抗震延性设计的方法，在设计实例中对框架构件的设计采用了新西兰规范和我国规范两种做法，并进行了比较，证明了采用修正的弹性分析方法的延性设计使结构具有更加足够的强度和良好的延性，具有较好的抗震性能。

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？

This is the basis for the 'automatic alarm' prediction strategy494: issue an alarm automatically after every earthquake above a certain size, on the chance that it might be a foreshock of a larger earthquake.

这就是'自动报警'预测战略的基础94：在每次超过一定规模的地震后自动报警，以便碰运气它可能是更大的地震的一次前震。

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"。

This report involves our research works in the fields of coseismic earthquake stress triggering, fault activities, free oscillation of the earth, precursory changes prior to earthquakes and earthquake forecast.

本研究报告涉及同震应力触发地震、断层活动、地球自由振荡、地震前兆和地震预报等多方面，但是钻孔应力-应变观测是贯穿其中的主线。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
