水中氘和氧-18的分析广泛应用于地球水圈的研究中。研究工作者系统分析了世界各地雨水和地表水中氘和氧-18的含量,总结了规律。大部分地区雨水中氘和氧-18含量服从于图1所示的雨水线公式:δD=8δ~(18)+10(Craig,1961)。雨水中δD和δ~(18)O值随纬度、
Deuterium and oxygen in water -18 analysis is widely used in the study of the Earth’s hydrosphere. Researchers systematically analyzed the contents of deuterium and oxygen-18 in rainwater and surface water around the world and summarized the law. The deuterium and oxygen-18 contents of rainwater in most areas are subject to the rainwater line equation shown in Figure 1: δD = 8δ ~ (18) +10 (Craig, 1961). The δD and δ ~ (18) O values in rainwater vary with latitude,
