摘　　要：2010年7月2日、2012年1月8日先后在新疆和硕县境内发生MS4.7和MS5.0两次地震,新43泉距两次地震震中均小于200 km,利用小波变换对气氡资料进行分析后发现,两次地震前3～6个月气氡资料出现异常.又对2012年轮台、和静两次5级以上震例进行验证,结果令人满意,认为小波分析方法是地震前兆数据处理的一种有效方法.Ms4.7 and MsS. 0 occurred in Heshuo County of Xinjiang on Jul. 2 in 2010 and Jan. 8 in 2012, and the epicenter distance of them to New 43 spring were smaller than 200 km. After analy- zing the air radon data using wavelet transform method, we found the anomaly appeared about 3 to 6 months before the medium-strong earthquakes. The earthquake cases confirmation result of Luntai and Hejing earthquake was satisfactory, so wavelet transform was an effective method for processing earthquake precursory observation data.
