摘要
基于单次散射Aki模型,分别讨论了数据采样、噪声、滤波器性能等因素对Q值数据结果的影响。作为实例,本文对浙江及安徽台网记录的37次ML3.0至ML4.3之间地震的数字地震波资料进行了计算,通过设置合理的与影响因素相关的参数,获得浙江省区域地震尾波平均Q值,结果较好地反映了相关区域地震活动性特征。
On the basis of the signal scatter Aki model, the effect of algorithm factors （including the data .sampling, noise, filter and so on） on coda Q value was respctiely disccussed in detail. The digital seismic wave data of 37 earthquakes with 3.0≤ML≤4.3 recorded by Zhejiang and Anhui Seismic network were calculated. The average coda Q value of Zhejiang area were obtained by setting the reasonable parameter which is correlated to the effecting factor. This result reflected well the sismisity of correlative area.
