| 摘 要： | 做出了３２°～４０°Ｎ，８９°～１０５°Ｅ范围内各经纬度结点１９８９年７月～１９９６年１２月长波辐射（ＯＬＲ）月距平值曲线．将各结点的曲线图按经纬度排列起来，构成ＯＬＲ时空序列剖面图．根据对这些剖面图的分析，研究了强震前ＯＬＲ的变化特征．结果表明，强震前１～４个月震中附近结点ＯＬＲ曲线变化出现异常，表现为反向变化或振荡型．有的地震前异常的空间展布呈条带状．

| Abstract: | Monthly departure curves of Outgoing Longwave Radiation (OLR) at the intersections of latitude and longitude in a range of 32°~40°N and 89°~105 °E from July,1989~Dec.,1996 are drawn.Analysing these curves,variation characteristics of OLR before strong earthquakes are studied.The results show anomalous variations with opposite direction or oscillation of the OLR curves appear 1~4 months before strong earthquake at the intersections around the epicenter.Anomalous intersections are distributed in the shape of the belt before some earthquakes. |
