| 摘 要： | 利用宁夏及邻区的数字地震波资料,选取2009-05-2010-10月M_L2.6以上的20个台站32次地震事件的268条波形记录,用遗传算法反演了宁夏及邻区介质非弹性衰减系数和台站场地相应.反演得到:宁夏地区介质非弹性衰减Q值与频率的关系为Q(f)=337.67f0.4554.其Q值和山西及浙江地区的结果最相近,可能预...

| Abstract: | 268 pieces of digital oscillograms of 32 seismic events of form M-L2.6 to M-L4.9 recorded at 20 seismologic stations located on Ningxia region and its adjacent areas occurred from May,2009 to Oct.,2010 were studied and the relation of inelastic attenuation Q value with media frequency in the crust of this area,the site responses of 20 stations were calculated with the genetic algorithm.The results indicate that the frequency-dependent relation of inelastic attenuation value Q in the studied area is estimate... |
