作者曾初次测定国际标准平均洋水V-SMOW的氧-17丰度,得0.03790(8)原子％~(17)O。今进一步对其它两种国际标准水样GISP(格林兰冰层降水)和SLAP(标准轻的南极降水)的氧-17丰度作比较测定。水样得自维也纳国际原子能机构IAEA。样品用BrF,法转化为质谱进样气O_2,操作同前。
The authors first determined the international standard V-SMOW oxygen -17 abundance of ocean water, 0.03790 (8) atomic% ~ (17) O. This compares further with the oxygen-17 abundances of the other two international standard water samples GISP (Greenland ice sheet precipitation) and SLAP (standard light Antarctic precipitation). Water samples obtained from Vienna International Atomic Energy Agency IAEA. The sample is converted to mass spectrometry sample gas O_2 by BrF, and the operation is the same as before.
