对比了竖向和水平向加速度、速度反应谱及谱与震级的变化特征。
The variations between both horizontal and vertical acceleration spectra, and velocity response with earthquake magnitudes have been compared.
在加速度反应谱一致的前提下,研究了近断层速度脉冲的工程特性。
Under the condition of acceleration response spectrum being consistent, the engineering properties of near-fault velocity pulse are studied.
这说明对于实际地震加速度图,其功率谱是与均值速度反应谱相对应的。
This means that for actual earthquake accelerograms their power spectrum corresponds to mean response spectrum.
So, when I threw that thing up and you caught it, what you are doing mentally was immediately figuring out where it started and at what speed.
所以当你接住我抛出的物体时,你大脑里的反应就是,立刻弄清它的初位置以及初速度
