采用Sato单次散射模型,利用高台地震台的近场数字地震记录,研究了临泽震群序列尾波Q_C值在60 s流逝时间下的变化特征,得到Q_C值随频牢的变化关系Q_C(f)=(27.67±2.94)f~((0.9924±0.0411)).分析发现:在中等地震频发时段,Q_C值变化起伏较弱且偏低;研究结果与民乐-山丹地震序列接近,故认为这个结果近似了祁连山地震带中段地区的介质特性.

By means of Sato scattering of single model and Gaotai seismic station of the near-field digital seismic re-cords, this paper studies the characteristics of Linze swarm sequence coda Q_C value, also draws a conclusion of Q_C value changing with frequency, which is Q_C(f) = (27.67±2. 94)f~((0.9924±0.0411)). Analysis found that during the period of frequent middle earthquake, ups and downs of Q_C values is weak and Q_C value is low; The results of this study is similar with the Minle-Shandan earthquake sequence. So we believe that this result is similar with the medium characteristics in the middle section of Qilian mountain.
