【摘要】 随着人们观测能力的提高和观测手段的改善 ,反映地球介质特性的Q值的研究不断深化和发展。人们不仅利用天然地震波对Q值进行测量 ,还在实验室内对地震波的衰减理论和测量Q值的方法进行了研究。利用天然地震波测量Q值的主要方法有 :利用地球自由振荡资料、利用体波、利用面波和利用尾波来研究Q值。而实验室中对地震波衰减的研究为衰减机理提供了研究基础。这些研究都不断地加深了我们对于地球内部介质的特性及动力学过程的认识。更多还原

【Abstract】 With the raising of people’s observation and development of observation measures, the Q-value studies reflecting the media characteristics of the Earth are continuously deepened and developed. The Q-value studies are not only studied by the natural seismic wave, but also in the laboratory, where the attenuation theory of seismic wave and observing method of measuring Q-value are studied. The major methods of measuring Q-value by the natural earthquakes are the ones of using the data of free vibration of earth, body wave, surface wave and coda. And the attenuation studies of seismic wave in the laboratory have provided studying base for the mechanism studies. All these studies have intensified our understandings to the media properties and dynamic process in the inner earth.更多还原
