non-stationary ground motion 非平稳地震波
non-stationary earthquake motion 非平稳地震动
The results may better reflect the non-stationarity of ground motion in time domain and are closer to reality than those by wave theory and stationary random vibration theory.
由于这种方法能较好地反映地面运动的时域非平稳性，所以得到的计算结果更真实。
Consequently, it is necessary to describe earthquake ground motion with local spectral density, which is time-dependent and can reflect the non-stationary characteristics.
因此采用能反映时频非平稳特性的时变谱密度(即局部谱密度)来描述地震地面运动是非常必要的。
Utilizing these statistical features, we can simulate the design ground motion founded on the theories of non-stationary time history.
应用这些统计特征，可模拟出符合统计要求的基于非平稳时间历程的设计地震动。
