【摘要】 2008年3—7月福建地区共发生4次中等地震,福建地下流体氟离子有多孔观测井,在震前或震后出现高值突跳的现象;2008年9-11月福建地下流体氟离子又有多孔观测井出现高值异常。本研究通过实验提出:该氟离子高值异常为非地震前兆异常,建议准备一支氟离子选择性电极作为备用电极,用于对比观测,以提高氟离子观测数据异常的判别。更多还原

【Abstract】 There are 4 middle earthquakes in Fujian Province from March to July, 2008.The phenomena of fluorine ion high value anomalies were occurred at some observation wells of subsurface fluid in Fujian Province before or after the earthquakes.The phenomena were occurred again from September to November, 2008, which were non precursory anomalies identified by the contrast experiment.The reserve fluorine ion electrode was proposed for the contrast experiment and raising the precision of the observation.更多还原
