【摘要】 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QC值在60s流逝时间下的变化特征,得到QC值随频率的变化关系QC(f)=(27.67±2.94)f(0.9924±0.0411)。分析发现:在中等地震频发时段,QC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。更多还原

【Abstract】 By means of Sato scattering of single model and Gaotai seismic station of the near-field digital seismic records,this paper studies the characteristics of Linze swarm sequence coda QC value,also draws a conclusion of QC value changing with frequency,which is QC(f)=(27.67±2.94)f(0.992±0.0411).Analysis found that during the period of frequent middle earthquake,ups and downs of QC values is weak and QC 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.更多还原
