| 摘 要： | 平面皮以两个不同的入射角进入分层均匀介质,利用Goupillaud的等时层模型和其精确的反演公式,可以得到两个相应的视阻抗的时间序列。为了得到分层均匀介质逐层的密度和速度的深度分布,本文提出了"层位对双"方法,并利用这种方法作了数值试验,结果是满意的。 |

| Abstract: | We consider the effect of the impinging of a plane wave on a surface of a stratified media at two different angles of incidence. The Goupillaud's equal-traveltime layer model and it's exact inverse formulas[1] are used, the time sequence of the video impedances can be computed.In order to compute the deepness distribution of the densities and velocities for the layered media, we propose in this paper "The contrast method of the layer-interfaces", by which, the computational experiments were made and the numerical results are satisfactory. |
