摘要
本文应用卫星接收的地气系统射出的长波辐射资料，分析计算了几次地震前长波辐射的异常变化。分析结果表明，云层对长波辐射月平均值的影响不大，所以长波辐射的大小可以反映下垫面的热状况。地震发生前，长波辐射的值都异常升高。因此，长波辐射资料的异常变化在地震的短期和临震预报方面有应用前景。
By using the data of outgoing long-wave radiation(OLR),received by the satellite,thispaper calculated the anomalous variation of OLRbefore several earthquakes.The results showthat the effect of cloud layer on the monthly mean value of OLR is only a little;the OLRvaluecan reflect the heat state of the ground;before the earthquakes,the OLR value rises obvious-ly.Therefore,the anomalous variation of OLR is of applied prospect for short-impendingearthquake prediction-
