测定天然水的氢同位素组成,是研究不同类型天然水成因的重要手段之一。为此,我们在北京地区32个点采了样,并进行了下述测定。方法:用金属铀还原法制备样品,H_2用MM602型质谱仪测定,标准样采用世界标准平均海水(简称
Determination of hydrogen isotope composition of natural water is one of the important means to study the causes of different types of natural water. For this reason, we sampled 32 spots in Beijing and conducted the following tests. Methods: Samples were prepared by metal uranium reduction method. H_2 was determined by MM602 mass spectrometer. Standard samples were analyzed by the world standard average seawater
