| 摘 要： | 利用Sato单次散射模型,使用甘肃遥测台网山丹台的近场数字地震记录,在60 s流失时间下研究了2003年甘肃民乐-山丹地震序列尾波Qc值的变化特征,得到Qc值随频率的变化关系.对于不同中心频率点Qc值变化形态不一致:在序列的发展阶段变化起伏较大,在序列初期和末期变化起伏较弱. |

| Abstract: | Using the Sato single scattering model, based on the near-field digital seismic records from Shandan seismic station of telemetry network of Gansu province, the change characteristics of coda Qc values of Minle--Shandan earthquake sequence, Gansu peovince, in 2003, are studied with loss time of 60 s. The relationship between the Qc values and frequency is obtained. For different center frequency points, the change from of Qc values are different. In develop stage of the frequency, Qc values changed with great fluctuations, and in early and late stages, the changes were weak. |
| Keywords: | Sato model Minle-Shandan earthquake Characteristic of Qc value |
