基于单次散射模型的近震尾波Q值计算软件的研制
|
摘要
介绍了一套基于Aki单次散射模型在Visual C++6.0平台上开发的近震尾波Q值计算程序,并应用于2005年11月26日九江—瑞昌5.7级地震余震序列的分析。本软件的研制成功,使地震近震尾波Q值计算常规化成为可能。
The authors develop a program in Visual C++6.0 development platform to calculate local seismic coda Q value,based on a single scattering model of Aki.It's applied to calculate the coda Q values of the aftershocks of Jiujiang-Ruichang M 5.7 earthquake occurred in November 26,2005.The routine work of the local seismic coda Q values calculating will be possible by using their program.
