摘要
通过对格尔木井水氡的正常动态、干扰动态和异常动态的分析,认为该井水氡多年正常动态平稳起伏,呈连续的“n”型变化,低点具有1.5～4年左右的变化周期;在排除干扰动态后,对两段明显的异常动态,引入同井动水位进行对比研究,认为两者之间存在一定的负相关关系.水氡正常动态的变化受控于动水位的变化,动水位受自流井补给区附近降雨、冰需融化等因素的影响.未发现令人信服的水氡前兆异常.
Through the analysis of the normal dynamic, interference and Golmud, it is found that the normal dynamic of the water radon changes abnormal dynamic of water radon in stably, presented a continuous ＂n＂ type change, lower points were in the period of 1.5- 4 years. After cleaned the dynamic interference, two periods of abnormal dynamic were compared analysis in the same well dynamic water level, the results showed in the around area. The truly water radon anomaly was not found.
