【摘要】 2009年9月份之前,聊古一井水汞观测值在正常范围内波动,9月1日聊古1井水汞观测中出现高值异常,经过重复观测,水汞浓度是观测背景值的22倍。通过对流体测项其他敏感组分的分析和仪器运行情况的检查,没有发现异常。对观测环境现场调查发现,8月28日1支水银温度计不慎被打破,随后在不同环境下进行水汞对比观测分析,认为是水银温度计的破碎污染了观测室,致使水汞观测值大幅度升高,并非地震前兆异常。更多还原

【Abstract】 The mercury observation value of Liaogu No.1 Well fluctuated in well-balanced range,but it appeared a high value anomaly on Sep.1,2009.Through repeatable observation,the high value anomaly may be about 22 times of the normal amplitude.Through the analysis of other sensitivity elements of liquid observation instruments and examination of apparatus run instance,the anomaly was not found.The thermometer was broken in Aug.28 in Hydrochemica Chamber by the survey.Subsequently,based on the analysis of contrast observation in different environment,we considered that the fragmentation of thermometer polluted Hydrochemica Chamber,which rendered the anomaly.The result was that the anomaly was not novel portent of earthquake.更多还原
