摘要
惰性气体在地下水中的溶解量主要取决于水温和气体分压.而且溶解度在常见的水温范围内是水温的单调函数.因此,当深层地下水系统处于封闭状态,系统中不存在蜕变成因的惰性气体源时,可将溶解的惰性气体作为指示地下水形成温度的天然示踪剂.
The concentration of the noble gases dissolved in groundwater depends mainly on the water temperature and the partial pressure of the gases and is , in normal temperatur range , the monotonous function of the water temperature. Therefore, the dissolved noblegases can be used as natural tracing elements to estimate the groundwater pal-eotemperature, if the deep flow system is a confined one and meanwhile there is no radiogenic or metamorphic noble gases in it.
