The oxygen isotope ratio of the ocean changes as a great deal of water is withdrawn from it by evaporation and is precipitated as snow to form glacial ice.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。
2
The effect on heat transfer performance caused by heat flux, gradient and liquid-filled ratio of evaporation end was deeply investigated.
分析了热管的启动特性以及热流密度、蒸发段倾角和充液率对其传热特性的影响。
3
The isotopic ratio of lithium was determined by cumulating intensity of ion current during evaporation of all samples on evaporation filament.
