| 摘 要： | 利用红山数字地震台记录到的,自2001年3月到2006年7月近震波形资料,采用从i的尾波单次散射模型计算了该台站周围50 km内的尾波Qc值;该范围代表了邢台震区的地下介质的特征,经多地震拟合后得出尾波与频率的衰减关系.并给出震区的尾波Qc值随时间的变化结果,发现在邢台2002年4月22日的M5.0级地震前后尾波Qc值由低升高然后再降低. |
| 关 键 词： | 单次散射模型 尾波Qc值 介质性质 |

| Abstract: | This essay, based on the near earthquake waveform data from March 2001 to July 2006, calculates with the coda Aki single scattering model the coda Qc value 50kin around Hongshan Seismic station. This area represents the scope of Xingtai seismic region which shares the same underground media features. Thus we obtain the variation relationship between Qc value and the frequency. We find before and after the April 22, 2002 Ms5.0 Xingtai earthquake, the Qc coda value changed from low to high and then high to low. |
| Keywords: | single scattering model Qc value of coda wave medium character |
