This means that for actual earthquake accelerograms their power spectrum corresponds to mean response spectrum.
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。
2
With the power spectrum converted from the goal response spectrum, it is easy to generate the artificial accelerograms compatible with response spectrum.
利用由目标反应谱转换的功率谱可较简便地制作拟合反应谱的人造地震波。
3
Then a new iteration method is developed for generation of random accelerograms non-stationary both in amplitude and frequency which are compatible with target.
