We have developed an analytical method of hydrogen isotope ration of small amount of water contained in rocks. For the complete reduction of water without isotopic fractionation, specific zinc regents should be used and water vapor pressure should be optimized. This suggests that continuous zinc evaporation breaking oxide tunic is essential.

建立了岩石中微量水的氢同位素比值分析方法。为了在没有同位素分馏的情况下完全还原水，应使用特定的锌试剂，并应优化水蒸气压。这表明连续的锌蒸发破坏氧化膜是必不可少的。
