关于区域性的地震面波层析反演方法的讨论

DISCUSSION CONCERNING WITH TOMOGRAPHIC INVERSIONS OF SEISMIC SURFACE WAVES

讨论了在地球表面局部区域进行面波层析反演时所用的各种反演方法，指出各种方法用于区域性层析反演时的优缺点，并就由面波资料对区域性的地壳和上地幔结构进行反演的方法──分块反演方法、本征函数展开法、球面雷当变换方法、Ｔａｒａｎｔｏｌａ概率方法和波形反演的方法进行了讨论。指出了各种方法的优缺点及适用范围，并对一些方法进行了数值模拟，给出了计算实例。

Different methods concerning with tomographic inversions of seismic surface waves on the regional earth structure have been discussed in this paper.The advantages and defects are evaluated for these inverse methods. Block inverse method, eigenfunction expansion method,spherical Radon transform method,Tarantola probability method and waveform inverse method for the regional crust and mantle structure inversion from the seismic surface waves have been discussed here. Advantages and defects of these methods are appraised.The numerical simulation examples are given for some inverse methods.
