| 摘 要： | 本文根据白家疃台６０年代以来的短周期地震记录图，分析了区域震相的强度比。研究表明：Ｓｎ／Ｌｇ波的强度比波传播路径上岩石层热结构、热状态及强地震活动等均有相关性，并就这种相关性对于强地震成因及其预测研究的直接意义进行了讨论。

| Abstract: | By analyzing seismograms of short period records of the Beijing Seismological Observatory the present paper investigates the amplitude ratio of regional seismic phases. The results indicate that the amplitude ratio of Sn/Lg is correlated with the lithospheric structure, thermal state and strong earthquake occurrence in the region where the seismic rays pass through. The significance of such correlation in the study of strong earthquake genesis and their prediction is discussed. |
