摘要
利用安徽省测震台网记录到的中小地震Ｐ波记录，采用频率域方法，测定了本省区域范围内１９８５－１９９５年间地壳介质的Ｑ值。对结果的分析研究表明，使用震中距８０－１３０ｋｍ的地震Ｐ波记录测定地壳介质Ｑ值具有优越性，本地区介质特性Ｑ值与震中距间线性关系较好，本地区地壳Ｑ值目前处于中低值状态。
Made use of the frequency method and the P-wave information of medium and small earthquakes recorded by the seismic network in Anhui province . the Q-values of the crustal media in Anhui province during the period from 1985 to 1995 have been determined in this pa- per , and the Q --values determined by using P-wave information of earthquakes with epicentral distance 80-130 kilometers are morereasonable , the Q-values have a better linear relation be- tween the epicentral distance and the magnitude , and the present Q-values are moderate-low Value condition in this area.
