| 摘 要： | 阐述了氡在地下水中的不同存在形式及不同形式氡的运移机理和传递地壳应力应变信息的机理，结合实际观测结果对其映震效能的差异性进行了研究。结果表明：逸出氡比溶解氡能更好地反映地壳的应力应变的变化，其映震效能明显高于溶解氡。因此，逸出氡可作为新的映震组分纳入水化台网观测，从而成为地震监测与预报的一种较有效的手段。

| Abstract: | In this paper, the different existence forms of radon in underground water are expounded, the mechanisms in which different forms of radon travel and pass the information of crustal stress and strain are discussed and the differences of their reflecting earthquake efficiency are studied. The results show that escaping radon reflects better the crustal stress and strain and earthquake than dissolved radon. Thus, escaping radon can become a new and sensitive reflecting earthquake component of observation net of hydrochemistry for predicting earthquake. |
