【摘要】 对清丰水化站地下水中溶解气CO₂多年的观测资料序列进行了研究分析,其结果是:该测项对观测装置的改变及抽水量的变化反映灵敏;对本观测井所在构造带上的4.0级以上的地震,有明显的前兆异常;该测项与大气压力及气温的相关系数跟各时段的抽水量和抽水装置的吃水深度有关。更多还原

【Abstract】 The soluble CO₂ in water at Qingfeng pumping station was observed for several years and the data were analyzed. The results revealed that this examination has high sensitivity to the change of both observational instrument and pumping water, and anomaly feature of earthquake precursor was obvious in the observation well before M4 of earthquake. They have some relevance with relevant coefficient of air pressure, air temperature, pumping water and the depth of water pump in the well.更多还原
