Experimenting the result expresses that different earthquake wave has little influence to frequency.───试验结果表明，不同的地震波对卓越频率的影响不大。
Key points: earthquake wave and magnitude.───重点：地震波和震级。
Representing amortization reference set-up, earthquake wave access and earthquake motion input as well.───探讨了阻尼参数的设置、地震波的选取、地震动方向的输入等问题。
Compared with earthquake wave and acoustic wave, Ground Penetrating Radar has many advantages in this work, and has been used widely.───在这项工作中，探地雷达比地震波，声波较为方便，能够满足工程的精度要求，得到了广泛的应用。
That day afternoon, the earthquake wave of southwesterly direction affects quickly the countrywide other area that includes Beijing inside.───那天下午，来自西南方向的震波迅速波及到包括北京在内的全国其他地区。
Earthquake responses of top structure and conical bearing are analyzed by inputting earthquake wave with different magnitudes and types.───通过输入不同类型的地震波，分析上部结构和锥形支座的地震反应。
Ratio similitude design of model and earthquake wave input was unified for reflection dynamical characteristic of actual structure.───试验中地震波输入和模型结构尺寸采用统一试验相似比设计，以尽可能反应真实隔震结构的动力特性。
Ductility demands of single-degrees-freedom system under an earthquake wave don't always increase as strength reduction factors increase.───在单条地震波作用下，单自由度体系的延性需求并不总是随着强度折减系数的增加而单调增加。
Finally, the influence of vertical earthquake wave on the seismic response of structure was studied.───最后研究了竖向地震作用对结构地震响应的影响。
Through the frequency spectrum analysis of earthquake waves and the dynamic instability regions analysis, the dynamic stability of serial system can be judged under a certain earthquake wave.
The shock absorbing effect of the damper-isolated system excited by sinusoidal wave and general earthquake wave is also analysed.
Choosing earthquake wave, designing table-board import, the test datum were analyzed, seismic behavior such as amplification coefficient, predominant frequency changes etc. were obtained.
This paper selects the routine earthquake wave and inputs frame house.
The results showed that the main frequency of the earthquake wave produced by the source is higher obviously than ordinary seismic explosive columns.
This system realizes the collection, transmission and data processing of earthquake wave signal by means of delta modulation, frequency-shifting keying, frequency-division multiplexing technologies.
According to the similarity principle, different models were adopted to simulate various geological constitutions, based on the physical nature of the earthquake wave spreading.
Earthquake wave: P, S and surface wave.
Strong earthquake wave, it go the rounds whole earth according to imperceptible speed and method.
