摘要 利用红山数字地震台和邯郸数字地震台网记录到的2001年3月~2006年7月近震波形资料，采用Sato尾波单次散射模型计算了邯郸邢台地区不同尾波窗长(20 s、30 s和40 s)的QC值,不同时间窗长QC值的平均结果分别为 35.8 f 0.95、46.0 f 0.94 和59.4 f 0.93 。Q0值分布受地质构造因素影响呈现出明显的横向不均匀性。总体而言,研究区内Q0值较低，η值高，QC值对频度的依赖性强，随频率的增大衰减较快。
Abstract：By use of the near shock waveform data from Hongshan digital seismostation and Handan digital seismological network from March, 2001 to July, 2006, QC values with different window length of coda waves 20 s,30 s, 40 s in HandanXingtai region are calculated with Sato singlescattering attenuation model, the average QC results in different time windows is 35.8 f 0.95,46.0 f 0.94 ,59.4 f 0.93 respectively. In the studied area ,Q0 value affected by tectonic factors shows obviously lateral heterogeneity,generally,Q0 value is lower, η value is higher, QC value strongly depends on the frequency and decreases rapidly with the frequency’s in creasing.
