| 摘 要： | 利用接收函数和地震面波频散联合反演台站下方速度结构,已成为一种常用技术.联合反演结果能同时匹配两个不同数据集合,使得解的非唯一性在一定程度上得到了有效抑制.然而对于现有地震台站分布,短周期面波由于受多种因素的影响,可以获得的有效频散资料较少,层析成像的横向分辨率较低,难以反映台站附近局部介质真实的频散特性,而且这些面波...

| Abstract: | The joint inversion of receiver functions and seismic surface wave dispersion has become a common technique to study the velocity structure beneath stations.The results can simultaneously match the two data sets of different resolution so that the non-uniqueness of solution has been effectively suppressed in a certain extent.However,for the present distribution of seismic stations,due to many factors,there are less effective short-period surface wave dispersion data.The horizontal resolutions of seismic tom... |
