摘　　要：利用乌什台和阿合奇台1992~2013年积累的地倾斜观测资料,采用形态法、矢量法对40个MS5.0以上地震前出现的异常变化进行统计分析与对比。在模拟记录期间震前异常特征表现为葫芦串、错动、抖动、矢量打结转向、年变畸变,在数字记录期间震前异常特征表现为高频抖动、固体潮畸变、矢量打结转向、年变畸变。两个台站地倾斜异常特征相同点为都有年变畸变和矢量打结转向,而且震前都会出现一些临震异常;不同点表现为异常形态的幅度、形状不同,且出现在不同分量上。The statistic and comparative analysis was done with form and vector analysis method to extract the anomaly change of ground tilt data before 40 MS5. 0 earthquakes in Wushi and Aheqi seismic station from 1992 to 2013. The anomaly of analog data was calabash brunches,diastrophism,vibration,vector being knot and changing direction,annual distortion. The anomaly of digital data was high frequency wobble,earth tidy distortion,vector being knot and changing direction,annual distortion. The ground tilt anomaly similarity between two seismic stations was vector being knot and changing direction,annual distortion,and there was some impending anomaly before the earthquakes. The ground tilt anomaly difference was the amplitude,shape and showing in different ground tilt component.
