氧气

At this altitude the atmospheric pressure is half that at sea level, and thus delivers half the amount of oxygen per lungful.

在这里空气压力只有海平面的一半，因此每次吸气只能得到一半的氧气供给。

Present paper deal with the results of lysimeter studies on soil conditions under varying rates of water percolation.

This paper mainly introduced different oxidation methods,but oxygen,manganese dioxide and manganese sesquioxide were mainly studied.

本文通过采用不同的氧化剂氧化间氟甲苯合成间氟苯甲醛，重点研究了氧气，二氧化锰和三氧化二锰的氧化效果，分别研究了它们的氧化工艺条件以及固体氧化剂的循环利用，并初步探讨了它们的氧化机理。

This Standard Reference Material is intended for use in the measurement of the oxygen gas transmission rate of thin polymeric films using manometric, volumetric, or coulometric methods.

这种标准参考材料用于聚合体薄膜的氧气透过率测试，测试方法可以是压力法、体积法和库仑法。

An extremely high temperature of anode humidification is also unreasonable; as a result, when the current density is high, the liquid water should be injected directly into anode gas channel to guarantee both high inlet H〓 concentration and well-humidified membrane. 4. The utilization of Pt in the cathode catalyst layer will decrease with the increasing current density; as a result, based on the principle of maximal Pt utilization, the catalyst layer can be designed much thinner or not uniformly in the catalyst distribution.

而在此截面上，交指型流场燃料电池阳极侧的液态水饱和度的极值位置并不确定；在电池阴极处，液态水饱和度的极值总是出现在z=0.002m处的气体扩散层和膜的界面上，并且该处的液态水饱和度沿x方向存在一个最大值，与此相应的氧气的质量浓度分数在该处达到极小值，因此极限电流密度将首相出现该处，但总体来说液态水饱和度沿x方向的分布较为均匀。4。
