图6 选定Marmousi2模型待反演区域一(图中裂隙为含水区域)的原始剖面与反演结果剖面 a、b、c、g、i—分别为纵波速度、横波速度、密度、ε、δ原始剖面; d、e、f、h、j—分别为纵波速度、横波速度、密度、ε、δ反演剖面

Fig.6 Original profiles and inverted results of region 1(water-bearing fracture) in Marmousi2 model a,b,c,g,i—are original profiles of P-wave velocity,S-wave velocity,density,ε and δ respectively;d,e,f,h,j—are inverted profiles of P-wave velocity,S-wave velocity,density,ε and δ respectively
