本文在强震地震波频散研究的基础上,进行了强地震动场相位预测方法和多点地面运动时程合成方法的研究。
A method for predicting the phase spectra of strong ground motion is presented based on the equivalent dispersion of wave motion and the approach for synthesizing ground motions is then studied.
但是人的听觉范围大约是10个倍频程,因此人们希望任何合理的合成器V CO其操作范围至少应有5个倍频程,以达到音乐方面的有效性。
However, the range of human hearing is about 10 octaves, and any reasonable synth VCO is expected to operate over a range of at least five octaves to be musically useful.
据此幅值谱和一个随机相位谱,并与一个时程包络函数结合,合成一个子震时程。
A time history is synthesized from this amplitude spectrum and a random phase spectrum, combined with an envelope function.
