Web摘要本文利用中国数字地震台网位于东北地区的122个宽频地震台站的18个月记录的三分量连续地震噪声数据，采用互相关方法提取了Rayleigh和Love波经验格林函数，并利用时频自动分析技术获取了相应的相速度频散曲线.通过反演频散曲线，获得了Rayleigh和Love波周期为8～35 s的二维相速度分布.结果表明 ... WebApr 11, 2024 · Examples of calculations of the root of the generalized Rayleigh equation N (α) = 0 are shown in Fig. 2. Here we show the dispersion relations in terms of prescribed frequency of the process ω and the evaluated root α 0 (Fig. 2 a). Corresponding values of the Rayleigh waves phase velocity c g r = ω / α 0 are presented in Fig. 2 b.
