一、国内外研究与应用简况 国外用放射性氚判定地下水年龄,从而解释地下水补给、运动及污染情况等,它是一种便于掌握、效果显著、投资少、收效快的好方法,它将逐步成为水文工作者不可缺少的先进手段之一。据1974年3月11～15日,在奥地利首都维也纳召开的国际地下水水文学同位素技术会议报道,已有27个国家程度不同的应用于生产实践中。 First, the domestic and foreign research and application of profiles of foreign groundwater with radioactive tritium to determine the age of groundwater to explain groundwater recharge, exercise and pollution, etc., it is easy to grasp, the effect is significant, less investment, quick and good way, it will gradually become Hydrological workers indispensable to one of the advanced means. According to the International Conference of Groundwater Hydrology Isotopes, held in Vienna, Austria, from March 11 to 15, 1974, 27 different levels of production have been used in practice.
