| 摘 要： | 本文以P波和SV波波场比值,提出层状介质情况下透射波波场的反向重建算法原理,并据此给出在已知介质速度值时,求介质层厚度的反演方法。文中还以深源远震记录波形资料给出反演算例,证实本文的算法是可行的。

| Abstract: | Under the assumption of horizontal layering, the principle of wave field reconstruction from the ratio of P and S wave fields is presented and based on this principle, an inversion method is given from which the thickness of the media can be obtained assuming that the velocity in the media is known. By inverting the deep-foucus teleseismic wave form data, the validity of the present method is verified. |
