英文摘要	考虑震源区为各向异性ATI介质情形下,给出了剪切位错源地震矩张量解析表达式并模拟了震源区各向异性对双力偶分量(DC)、补偿线性偶极子分量(CLVD)和各向同性分量(ISO)的影响.结果表明,即使剪切位错源仍能产生非双力偶各向同性分量,其导致沿着ATI介质对称轴方向体积变化;当断层面位于ATI介质对称平面或者震源区为各向同性介质时,剪切位错源在辐射意义上才可等效为双力偶机制.; Assuming the fault zone as anisotropic ATI media, the analytical expressions of seismic moment tensor in ATI media have been derived, furthermore, we have modeled the effect of anisotropic parameters on DC, CLVD, and ISO. Some results have shown that shear faulting can also generate isotropic component which will lead to volume change along ATI symmetry axis, however, when fault surface is located in the symmetry plane of ATI or fault zone is isotropic structure, shear faulting can be regarded as double couple mechanism in terms of radiation pattern.; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 3; 07; 1772-1782; 54
