中文摘要：

Q值结构对了解地壳的非弹性性质、地壳内部构造、热活动状态、地壳介质非均匀性以及断层分布有着重要的意义.编写了基于吸收特征时间t＊的三维Q值层析成像人机交互软件,可以方便快捷地计算地震体波（P波和S波）的振幅谱并通过拟合振幅谱得到反映地震波衰减的吸收特征时间t＊,并利用t＊资料通过三维Q值层析成像方法得到三维Q值结构.实际观测资料处理结果表明,文中给出的方法和软件是有效且可行的.

英文摘要：

Q-value structure of the crust is of great significance for understanding of non-elastic nature of crustal structure,thermal activity,crustal inhomogeneity,and fault distribution.We present an interactive software for three-dimensional Q tomography based on absorption characteristic time t＊.Amplitude spectra of seismic data（P-wave and S-wave） can then be calculated quickly and easily,absorption characteristic times can be obtained through fitting amplitude spectra,and three-dimensional Q structure can be obtained by using the Q tomography method and t＊ data.The real example shows that the method and software are effective and feasible.
