| 摘 要： | 利用山东数字地震台网和青岛数字地震台网的地震波形资料，基于单次散射模型的尾波小波包分析方法，计算了青岛地区4个台站附近的尾波Q值，拟合得到青岛地区及附近海域尾波Q值随频率的变化关系为：Q=123．5×f^0.9；并对2003年6月青岛市王哥庄的4级震群序列的Q值进行计算分析，结果表明，在震群期间Q值变化不大。

| Abstract: | Based on seismic waveform data of digital seismic networks of Shandong and Qingdao,the Q-values of coda wave of the area around 4 seismic stations of Qingdao are calculated by using analysis method of wavelet package on single scattering model.The variation relationship Q-values with frequency of coda wave(Q) in Qingdao and its adjacent see area is obtained by fitting,being.Also,the Q-value for Wanggezhuang M4.0 earthquake swarm sequence in 2003 June in Qingdao city is also calculated and analyzed,indicatin... |
