The initial model ( vs , vp , qb , p ) based on previous work of this research group is adopted , and by terms of the relationship between the attenuation factor and s - wave quality factor , the stochastic least square is conducted to inverse the o > > of ail layers under every grid , i . e . the qb structure of every uiut - column Q _ 、 p ) ,利用衰减系数和层内s波品质因子q _之间的关系,通过阻尼最小二乘法反演方法反演每个单元格内各层q _ ,得到每个“单元柱”的q _三维结构
This is of very important significance to understand the material property and geodynamic of corresponding area , , the surface wave attenuation mechanism and the inversion algorithm of attenuation and s - wave quality factor are discussed systemically in this paper . some important fruits and understanding are resulted from the the crust and upper mantle tomography of china . ( 1 ) calculating of the rayleigh surface wave attenuation factor y 本文首先探讨了面波衰减的机理,对面波衰减和s波品质因子q _反演的计算方法进行了系统的研究,并对中国大陆地区地壳上地幔q _三维结构进行层析成像,取得了以下重要成果: ( 1 ) rayleigh面波衰减系数计算。
X4 ? gridding attenuation and 2 ? x2 ? gridding group velocity are calculated respectively , based on the attenuation and velocity , the distribuation of rayleigh wave quality factor qr are yielded finally . ( 3 ) building the s - wave quality factor og3d structure of the continental crust and upper mantle of china area 为此把中国大陆区域划分成4 4网格和2 2网格,利用lsqr方法分别进行衰减系数和群速度网格化反演,得到4 4单元格的衰减系数分布和2 2单元网格的群速度分布。
2 ) the effects on waves conversion are stronger in rocks with dry fractures than that in rocks with water - filled fractures , and s - waves attenuate more rapidly in rocks with water - filled fractures . 3 ) the explosive point source which locates in anisotropic media can excites not only p - waves but also s - waves . 4 ) the properties of waves propagation were discussed and compared for several point sources with different source functions 结果表明: 1 )平行排列裂缝造成的各向异性使波前变宽; 2 )含干裂缝岩石对波型转化的影响比含充水裂缝岩石的大,横波在含充水裂纹中传播时衰减较快; 3 )当介质存在各向异性时,爆炸点源产生的波不仅有纵波,还有横波; 4 )通过改变点源函数研究不同点源所产生波以及波型的转换。
