摘　　要：将NASA官方网站下载的OLR原始数据资料,处理为二维空间数据和单点时序数据,通过地震目录核实对比,利用OLR月平均场演变法和月平均场距平法分析1974年以来内蒙古及周边地区发生的337次地震事件(Ms≥5)前,长波辐射的时空变化特征。结果发现:在震前约3—5个月,在许多地震前长波辐射(OLR)出现明显的异常反映,许多点位在震前异常比较明显。Using OLR primary data downloaded from NASA wehsite, throng the processing for two- dimensional space datum and simple point time-sequence datum, and consulting the earth- quake catalog, the OLR temporal-spacial characteristics before 337 earthqaukes （Ms≥5） located in Inner Mongolia and its neighbor （N35°-55°, E95°--130°） region scince 1974 have been analyzed with OLR monthly mean field method and OLR monthly mean field anomaly method. It is discoved that, before 3--5 months of earthquakes, long-wave radiation （OLR） all appeared the obvious exceptionally change before many earthquakes; earthquake. In many positions the anomalies are also obvious before earthquake.
