摘要
本文在Aki(1969)一次回弹散射理论基础上,用超声岩石模型模拟地方震,对地方震尾波进行了初步观测和讨论。观测结果得出见波波形、功率谱、持续时间相对于不同震中距是稳定的;并且尾波震相不可以追踪。这就支持了关于尾波的散射理论,同时也为地方震震级、地震矩和Q值等的研究以及地震图资料的充分利用提供了新的途径。
Band on the theory of Aki's coda, the local earthquake was simulated by ultrasonic test and the coda wave phase was diSCussed in this poper. The resultS show that the waveform.Power spectrum and continuous thee of the coda wave are steady relative to epicentral distance and the cods wave Phase isn't able to be trscked. This resultS backed a theory of coda scattering.
