| 摘 要： | 利用大柴旦数字地震台记录的2008年6.3级和2009年6.4级的数字地震资料,系统地分析了大柴旦地震序列尾波Q值随时间的变化,着重分析了尾波Q值在强震前的短期变化特征.结果表明,Q值在大震前后有较明显的变化,基本趋势是震前Q值增高,震后降低.

| Abstract: | By using the digital data of earthquakes with Ms6.3 in 2008 and Ms6.4 in 2009 recorded by Dachaidan seismic station,the coda Q-values variation with time in Dachaidan earthquake sequence is analyzed,especially the coda Q-values variation in short period before strong events,and the results show that Q-values change obviously before and after strong earthquakes,its general tendency appears that Q-values are high before the events and low after the events. |
