给出了宇宙线放射性同位素~（39）Ar测年的原理。介绍了本底、标准气体样品和气体比例计数系统等技术要求，用格陵兰冰样品进行~（39）Ar年龄测定，结果与其它方法测得的年龄一致。海洋水样的第一个结果表明，这种同位素有价值的信息，海洋混合和循环可以预期。地下水样品的39 Ar结果不同意一些含水层与conventional 14 C年龄，可能的解释进行了讨论，特别是地下生产的39 Ar。
The principles of a dating method based on the cosmic-ray-produced radioisotope39Ar are given. Technical requirements such as background and standard gas samples and gas proportional counting systems are described.With samples extracted from Greenland ice it can be demonstrated that39Ar ages agree with ages obtained by other methods. First results on ocean water samples show that with this isotope valuable information on ocean mixing and circulation can be expected.39Ar results on groundwater samples disagree for some aquifers with conventional14C ages; possible explanations are discussed, especially underground production of39Ar.
