摘要
对河北省地震局掌握的张北6．2级地震前河北北部及邻省山西的地壳形变资料利用周期滤波、调和分析两种方法进行了分析处理，获得异常12项，其中趋势异常10项，短临异常2项。本文分析了这些异常的特性及与张北地震的关系，同时针对这些异常分析了形变手段地震预报的现状及当前的困难，并探讨了今后的对策。
In this paper the crustal deformation data of Hebei crustal deformation approach before Zhangbei MS 6. 2 earthquake is analyzed with the method of periodical filtering and harmonic analysis, and twelve anomalies are obtained, which include ten tendency anomalies and two imminent anomalies. By studying the characteristics of the anomalies and the relation with Zhangbei earthquake,the current situation of prediction with deformation method and its difficulties faced are made clear,and that how to deal with these problem is discussed.
