摘　　要：分析了 2 0 0 3年 2月 2 4日巴楚—伽师 6 .8级地震前、后近场形变台站资料的变化情况 ,找出了震前出现的单分量变化、矢量打结等中短期、短临前兆异常 ,并初步讨论了该地震前、后的地震活动与固体潮汐关系。Around the Bachu-Jiashi M-S6.8 earthquake of Feb. 24, 2003, the data observed at near-field deformation stations showed various kinds of changes. It is thought through the analysis that single component changing and vector knotting were the characteristics of short-term and impending-earthquake deformation anomaly. The relation between the seismicity and solid tide before and after the shock was discussed.
