-
摘要: 利用红山数字地震台和邯郸数字台网记录到的2001年3月~2006年7月近震波形资料, 采用Aki的尾波单次散射模型计算了邯郸—邢台地区不同尾波窗长的Qc值, 窗长为20s时该区域的平均值为Qc=78f0.92, 40s时Qc=144f0.88。在研究范围内呈现出北高南低的态势。Abstract: Based on Aki single scattering model, the QC values with different coda window in Handan-Xingtai area are calculated with the seismic wave data recorded by Hongshan Seismostation and Handan digital Seismic network from March of 2001 to July of 2006.The mean QC value is 78f0.92, when window length is 20s, and is 144f0.88, when window length is 40s.The Qc value is high in south and low in north.
