摘要

采用旬变化率新方法分析了河北怀来4井水汞观测资料。结果表明,河北张北M6.2地震前怀来4井出现了明显的水汞短期异常变化。用旬变化率新方法对怀来4井水汞短期异常的特征作了分析。认为,水汞的短期异常显示是有普遍性的,在判定异常时必须采用合适的数学分析方法方能奏效。
Observed data of mercury in groundwater from the well No.4 in Huailai,Hebei,is analyzed by using a new ten-day rate of change method.The result shows that obvious short-term anomaly in mercury in groundwater from well No.4 in Huailai turned up before Zhangbei earthquake of M6.2,Hebei.Characteristics of short-term anomaly in mercury in groundwater from well No.4 in Huailai are analyzed by using the new ten-day rate of change method. The authors think that short-term anomaly in mercury in groundwater will generally turn up.To judge such kind of anomaly,some suitable mathematical method must be taken.
