带时间参量t的Fourier变换频谱图及其应用

Fourier frequency spectrum with time parameter t and its application,

本文讨论了带时间参量t~*的Fourier变换的基本概念,并用此方法对超声地震模型实验接收记录的多次波进行了分析,其结果表明:带时间参量t~*的Fourier变换,不但在理论上是正确的,而且在地震记录的频谱分析中,也是一种有效的辅助手段。

The basic concept of Fourier transform involved with time parameter t* is discussed. The multiple reflections recorded in ultrasonic seismic modeling are analysed using this method. The analysis result shows that Fourier transform involved with time parameter t* is not only theoretically correct but also an effective supplementary means for analysing the seismic frequency spectrum.
