同时还要具体指定震动持续时间的级别。
You also have to specify a duration of shaking over a given level.
我们的确会使用震动持续时间来估计一些小型地震的震级。
We actually do use the duration of shaking to estimate the magnitude for some small earthquakes.
通过大量人工波及天然地震记录输入结构的分析,我们得到了地震动持续时间与结构弹塑性耗能之间的关系。
By introducing a number of natural and artificial ground motion records into structural analysis, the relationship between earthquake duration and energy absorbed by structures was obtained.
研究人员经分析各造访生物震动的频率、持续时间以及振幅发现,食虫椿象与蜘蛛的某些猎物的震动特点最为相似。
Then the researchers analyzed the frequency, duration and amplitude of each visitor's vibrations. And they found that assassin bug's vibes most closely matched some of those of prey.
最后,给定结构的损害取决于震动的振幅和持续时间。
Finally, the damage to a given structure will depend both on the amplitude of the shaking and its duration.
对于一个典型的地震记录,如果地震平稳段持续时间较短,采用非平稳随机过程描述其地震动特性较为合理。
For a typical earthquake record, if the duration of its stationary portion is rather short, such a record should be described in terms of a non-stationary random process.
