| 摘 要： | 利用成都区域数字化地震台网中的郭达山台、蒙顶山台和鲜家坪台记录的数字波形资料，对2001年2月23日雅江6．0级地震发生前后的39个前、余震作了波谱分析。结果表明这3个台的拐角频率比值在主震前后都出现了不同的变化趋势。并且不同台站之间的变化趋势也存在差异。

| Abstract: | Using the digital wave datum recorded by Guoda mountain station, Mengding mountain station and Xianjiaping station in Chengdu regional digital seismic station network to analyze the 39 earthquakes of Yajiang M6.0 earthquake sequence that occurred on Feb.23, 2001 by spectral analysis. The result shows that the change of corner frequency ratio on 3 stations before and after the main earthquake, and it is different between different statiots. |
