They are not exhalations like our daily colloquies and vaporous breath 讲台之上何谓无碍辩才,通常即指学究所以为的巧言令色。

Next , the air enters a high pressure distillation column where it is physically separated into a vaporous form of nitrogen at the top of the column and a liquid form of “ crude ” oxygen ( ~ 90 % o2 ) at the bottom 随后空气进入高压分裂蒸馏塔,分离成氮蒸气和“原始”液氧(含大约90 %的氧) ,氮蒸气在蒸馏塔顶部,液氧在蒸馏塔底部。
