利用面波衰减的Q模型，反演出近地表的Q值。
Surface wave Q model with attenuation is used to inverse near surface Q value.
研究结果显示，在频率域内，面波衰减系数分布与群速度分布具有一定的相关性。
The correlation property between the distribution of attenuation factor and that of the group velocity is indicated, in this study.
然而，利用这种性质来衰减观测的面波并非十分容易。
However, it is not trivially easy to use this property for the attenuation of the detected surface-waves.
