摘要
通过对位于北京城东光华热水井和城北小汤山温泉水中＾４Ｈｅ／＾２０Ｎｅ、＾４Ｈｅ／＾４０Ａｒ、Ｎ１／Ａｒ、Ｈ２／Ａｒ和ＣＯ２／Ａｒ比值监测资料的分析研究，阐述了气体在断层介质上的吸附与脱附的平衡原理，利用声发射振动作用合理地解释了地下水中的各若气体比值在地震前明显的异常变化机制。
By analysis and study of 4He/20Ne、4He/40Ar、 N2/Ar、 H2/Ar and CO2/Ar ratios monitored in Guang Hua hot water well and in Xiao Tangshan warm spring,this paper discribs the equilibrium priciple of gas absorption and deabsorption on fault medium, and reasonably describs the mechanism of the obviously anomlous variation of various gas ratios in groundwater before earthquakes by acoustic emission theory. The anomalous variation of the gas ratios, especially the noble gas isotopic ratios in groundwater have very good relation wity earthquakes.
