本文介绍了对于一个垂直入射的地震脉冲薄层响应的推导。讨论中发现,反射脉冲具有入射子波的时间导数的形式;其振幅与波在薄层中传播的双程旅行时间和由声阻抗的比率决定的系数成正比。本文还通过零相位信导研究了频谱带宽对界面分辨率和薄层响应的影响,并提出一种根据振幅或波峰至波谷的时间估算厚度的滤波理论。 This paper presents the derivation of the response of a vertically incident seismic pulse sheet. In the discussion, it was found that the reflected pulse has the form of a time derivative of the incident wave; its amplitude is proportional to the two-way travel time of the wave propagating in the thin layer and the coefficient determined by the ratio of acoustic impedance. In this paper, the effect of spectral bandwidth on the interface resolution and thin-layer response is also studied by zero-phase signal guidance. A filter theory based on amplitude or peak-to-trough time estimation thickness is proposed.
