摘　　要：利用中国FY-3气象卫星资料,通过分析多种仪器的亮温数据,对2013年四川芦山MS7.0级地震进行了再研究。结果表明:中国FY-3卫星星载多探测仪器,可用于立体监测地震多发区域,红外和微波亮温震区异常明显,能部分解释大地震前热红外异常的多种观点,说明FY-3卫星对地震预测具有一定的实用性和参考作用。Based on brightness temperature data recorded by several scientific instruments in the FY-3 me- teorological satellite, we study the 2013 Ms7.0 Lushan earthquake. The results show that there are obvi- ous infra red brightness temperature anomaly and microwave brightness temperature anomaly in the earth- quake area, which can partly explain the theory that there was thermal infrared abnormality before large earthquakes. So, the FY-3 satellite can be used for the monitoring of earthquake-prone zone and have prac- tical value and referenced significance to earthquake prediction.
