| 摘 要： | 利用大柴旦地区的5个台站的数字波形资料,计算研究了大柴旦序列波速比随时间的变化特征,分析发现：2009年8月28日大柴旦6.4级地震前,5个台站的波速比都出现了低值异常;该地震后的几次5级以上余震前,部分台的波速比对这些余震有异常反应。大柴旦地震台的波速比值对5级以上地震映震能力较好。

| Abstract: | The characteristics of VP/VS ratio variation with time is analyzed by the digital waveform data of five stations,and the results show that the VP/VS ratio appeared abnormal of low value around the epicenter of Dacaidan Ms6.4 earthquake,and this digital seismic waveform data may be helpful for earthquake prediction. |
