【摘要】 详细讨论了2003年以来宁夏及邻区弹性衰减系数Q值,对其进行分时段计算和讨论,得到宁夏及邻区2003~2005年、2003年、2004年和2005年地震的非弹性衰减系数Q值随频率f的关系,分别为Q(f)=553.8f0.292,Q(f)=615.2f0.274,Q(f)=683.2f0.233,Q(f)=728.6f0.230,得到祁连山中东段的非弹性衰减系数Q值随频率f的关系为Q(f)=671.6f0.307。更多还原

【Abstract】 The elastic attenuation Q value in Ningxia and its adjacent region was discussed in detail and calculated in different period.The inversion results indicate that the frequency-dependent of inelastic attenuation Q value in 2003～2005、2003、2004、and 2005 is estimated as:Q(f)=553.8f 0.292、Q(f)=615.2f 0.274、Q(f)=683.2f 0.233、Q(f)=728.6f 0.230 and the frequency-dependent of inelastic attenuation Q value in the middle-east segment of Qilianshan is estimated as:Q(f)=671.6f 0.307.更多还原
