| 摘 要： | 基于Sato单次散射模型,利用2007年3月13日福建数字地震台网记录的发生在福建省北部地区的45条ML≥2．0级地震波形资料,对福建北部地区尾波Q值进行了研究,研究中首先计算各条记录尾波4—18Hz间15个频率的尾波Q值,并对Q值与频率之间的依赖关系进行拟和,拟和结果为：Qc（f）=（150．34±42．51）f^（0.8214±0.2109）。

| Abstract: | Based on the single scatter mode （ Sato）, using 45 earthquake digital wave data of ML≥ 2. 0 earthquakes in north area of Fujian province since Mar. 13,2007 recorded by Fujian earthquake digital network, the average Q value of coda in relative region is calculated, and the relationship between Q value and frequency is fitted. The result is that Qc（f）=（150.34±42.51）f^（0.8214±0.2109）. |
