摘要
2002年5月,山西忻州奇村水汞观测出现短期高值异常变化,变化幅度是正常值的10倍左右,从变化时间上分析,比较好地对应了2002年9月3日太原ML5.0地震,但通过调查和对比观测等分析,认为此异常系仪器不稳定、试剂污染及所配试剂用的蒸馏水不符合规范要求造成的。
During May, 2002, the water mercury at Qicun, Xinzhou,Shanxi appears a large abnormal change, about 10 times of the normal amplitude, for short period . The time of this abnormal change is consistent with that of Sep.3th,2002 Taiyuan earthquake of M 5.0.Through an analysis based on the survey and contrast observation, it is found that the anomaly was caused by unstable instrument, polluted reagent, as well as distilled water out of specification, which is used for mixing reagent.
