| 摘 要： | 用高分辨率质谱计分析了重水中氢与氧的同位素组成；分析了重水的分子组成、质谱中的单电荷离子；利用高分辨率质谱峰相对强度，计算了重水中的氢氧同位素组成。结果表明，高分辨率质谱法分析重水，可同时分析其中的氢同位素和氧同位素，并且用样量小，结果可靠。

| Abstract: | The isotopic composition of hydrogen and oxygen in heavy water are analyzed by using a high-resolution mass spectrometer. The molecular forms and single-charged ions in the mass spectrum of heavy water are clarified. And the hydrogen and oxygen isotopic compositions in some heavy waters are calculated by the high-resolution mass spectrometer. The results show that hydrogen and oxygen isotopic composition can be analyzed in the same time by using high-resolution mass spectrometer, little sample is used and the results is reliable. |
