氧气

The aromatics were chlorinated to corresponding chloride with hydrochloric acid as chlorinating agent and trichloroisocyanuric acid as co-catalyst in the presence of sodium nitrite under mild conditions.

研究发现在NaNO_2存在时，氧气能够以HCl为氯化试剂，(来源：dc3cdcABC论文网www.abclunwen.com)以三氯异氰脲酸为助催化剂，在温和条件下将芳香化合物氧化氯化生成相应的氯代芳香化合物。

Even more important, neither is oxygen transmission through closures.

更重要的是，不是通过关闭来传输氧气。

The results show that the films are characterized by the amorphous microstructure and mainly composed of Si C bondings, C C bondings as well as a small mount of oxide impurity consorted with Si; the content of the C C bondings decreased after annealing in vacuum, meanwhile the Si C bondings content increased, annealing in vacuum is beneficial to the formation of SiC; after annealing at 800 in air, a thin dense layer of SiO2 formed on the surface, which prevented the oxygen from contacting with the film and effectively protected the inner SiC from oxidizing.

结果表明，薄膜主要以非晶为主，由Si--C键， C--C键和少量Si的氧化物杂质组成；在真空条件下经高温退火后，薄膜C--C键的含量减少，而Si--C键的含量增加，真空退火有利于SiC的形成；在800℃空气中退火后，薄膜表面生成一层致密的SiO2薄层，阻止了氧气与薄膜内部深层的接触，有效保护了内部的SiC。

About 50 years ago, Dr. Peterson and associates worked in the lab and found that sound corks do not transmit oxygen.

大约50年前，彼得森博士和同事在实验室中工作，发现健全的瓶塞不传输氧气。

For this to have a chance of happening, more numbers will have to be crunched, and planetary atmospheres analysed for signs of oxygen.

为了让此事有发生的可能，更多的数字将会减少，行星大气层将会被分析以寻找氧气的迹象。

For this to have a chance of happening, more numbers will have to be crunched, and planetary atmospheres analysed for signs of oxygen.

为了这个希望有机会发生，人们不得不去处理更多的数字并对行星的大气成分进行分析以求发现氧气的存在。

For this to have a chance of happening, more numbers will have to be crunched, and planetary atmospheres analysed for signs of oxygen.

为了能够得到这样一个机会，更多的数据将会得到运算，行星中的大气将会被分析可有氧气存在。

Cyclic anodic potentiodynamic polarization of titanium in aerated and deaerated green solution provides an interpretation on the corrosion behavior of the titanium in the FGD system.

在通氮气及通氧气之绿色溶液中进行直流电动态极化以探讨钛在FGD系统中不同位置腐蚀行为之差异。

Its subject coverage includes: ladle and tundish technologies to remove inclusions and prevent oxidation; and argon oxygen decarburizing, ladle degassing, filtering, secondary refining, and chemical analysis of slags.

它的主题涉及的范围包括：包和漏斗技术去除夹杂物和防止氧化作用；氩氧气钢的脱碳，包内去氧，过滤，二次精炼法，炉渣的化学分析。

When algae dies and decomposes, the process sucks much of the oxygen out of the water.

众多海藻的死亡和腐烂，导致海水中的大量氧气被消耗掉。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
