测定地下水补给温度与降雨量的最新方法——惰性气体法

The new method of determining groundwater supply temperature and rainfall by dissolved noble gases

地下水补给温度与降雨量是重要的水文地质参数,已有的测定方法大多只能给出其相对变化。本文介绍的惰性气体法能同时求得地下水补给温度与降雨量的值,其基本原理是:利用地下水中惰性气体的平衡溶解量计算出地下水补给温度;在得到地下水补给温度的基础上,利用地下水中惰性气体的“过剩空气”量计算出降雨量。该方法主要适用于封闭条件下的深层地下水。

Groundwater supply temperature and rainfall are important parameters to hydrogeology, but we just get their relative changes by existing methods in almost moment. The new method of determining groundwater supply temperature and rainfall by dissolved noble gases is discussed. The groundwater supply temperature value can be worked out with the volume of balance dissolving noble gas in groundwater, but the rainfall value can be worked out with the volume of overmuch dissolving noble gas on the basis of getting groundwater supply temperature. And this method is mainly adaped to deep groundwater in closed condition.
