Two of the most predominant characteristics of Surface Wave are Dispersion and Attenuation which are the effective tools to study the velocity structure and viscidity structure of the earth interior.
频敌和衰减是面波传播中的两个基本特征，利用面波频散和衰减可以有效地研究地球内部速度结构和粘弹性结构。
Through contrasting and analyzing, the particle vibration velocity were forecasted by the orderliness formula of attenuation of blasting earthquake wave is precise relatively.
经对比分析，所得爆破地震波衰减规律公式预测的质点振动速度具有较高的精度。
The rock acoustic parameters in this paper include wave amplitude, spectral amplitude, spectral area, spectral density, wave velocity and attenuation coefficient etc.
