氧气

And if that were not practical enough, others are looking at the role snowflakes have in catalysing the transformation of ozone into normal oxygen.

这也许还很难以付诸实用，（这个，，怪怪的，是这个意思么？），另外一些科学家正在探索雪花在臭氧转变成普通的氧气过程中的催化作用。

Among the commonly used oxidants (H_2O_2, TBHP etc), molecular oxygen is the cheapest and cleanliest oxidant.

与传统的氧化剂(H_2O_2或TBHP等)相比，氧气是一种清洁而廉价的氧化剂，对环境友好。

In reaction 12.01 kg of carbon is completely combusted with 22.39 m3 of oxygen supplied by air blast to yield 22.26 m 3 of carbon dioxide and 393.8 MJ of heat.

在反应12.01公斤的碳排放是完全22.39米燃烧3 空中爆炸的供应氧气产量22.26米 3 二氧化碳和393.8兆焦耳的热量。

Coal combusts in high-temperature flow of oxygen, and various forms of sulfur in the samples are generated into sulfur dioxide and a small amount of sulfur trioxide; when the infrared detector converts gas concentration to voltage signal, we can detect.

煤样在高温的氧气流中充分燃烧，试样中各种形态的硫分解出来生成二氧化硫和少量三氧化硫，由红外检测器将气体浓度转换成电压信号进行检测。

The results show that compound 1 combusts, decomposes, sublimates and loses weight simultaneously at 258℃ in oxygen, and the heat emitting from the combustion is far greater than that absorbed by sublimation.

结果表明，在氧气气氛下，三（2，4-戊二酮）合铱在258℃时开始燃烧分解，并伴随著升华失重，燃烧释放的热量远大于升华所需的热量，气相中的主要分解产物为2，4-戊二酮、二氧化碳和 2，5-二甲基-3-乙酚基映喃等。

They may be considered commensals, however, with stress, overcrowding, low oxygen levels, improper water parameters, changes in temperature or poor diet, the parasites can multiply and the fish may then develop signs of systemic disease.

它们可以被看作是 commensals ，不过，压力，过度拥挤，低氧气水平，不当的水分参数，温度的变化或穷人的饮食，寄生虫可以乘以和鱼，然后可能发展的迹象，全身性疾病。

Haemoglobin transports oxygen in the red blood corpuscles. When bound to oxygen it changes colour.

在血红细胞内，血红蛋白负责运载氧气；携带氧分子后，血红蛋白的颜色便发生变化。

Clair Folsome had extrapolated the results of his tiny ecospheres and calculated that you would need a sphere with a radius of 58 meters -- half air and half microbial soup -- to support the oxygen needs for one person indefinitely.

Clair Folsome 从他的那些小型生态圈中得出一些结论，按他的计算结果，你需要一个半径为58米的球体——半是空气半是微生物的混合液——来为一个人提供无限期的氧气供应。
