The oxygen isotope ratio of the ocean changes as a great deal of water is withdrawn from it by evaporation and is precipitated as snow to form glacial ice.
随着大量的水通过蒸发被抽离,并以雪的形式沉淀形成冰川冰,海洋中氧同位素的比率就发生了变化。
Furthermore, the background correction during the oxygen isotope ratio measurement with MAT-CH5 mass spectrometer was chosen as an example.
而且以MAT - CH_5质谱计测量氧同位素比时的本底校正作为例子。
