摘要
从地震波衰减品质因子(Q值)的含义及其研究意义出发,介绍了国内外利用天然地震的体波、尾波、Lg波开展地壳介质品质因子Q值研究的方法和动态,阐述了各种方法的方法原理及应用范围等,并展望了利用天然地震研究介质Q值的趋势。
Starting from the definition and significance of quality factor Q value, the main methods and developments of estimating Q value by using natural seismic waves, e.g. body waves, coda waves and Lg waves have been introduced respectively, as well as its corresponding principles and application limits are explained. The prospective on the study of seismic wave attenuation by use of earthquakes is discussed.
