甲烷

He advancement of direct partial oxidation of methane to syngas over transition metal catalyst s was reviewed.

综述了过渡金属催化剂催化甲烷直接部分氧化制合成气反应的进展，讨论了关于催化剂活性中心的一些观点和两种有代表性的反应机理。

"The simplest member of the paraffin hydrocarbon s, methane burns readily, forming carbon dioxide and water if supplied with enough oxygen for complete combustion or carbon monoxide if the oxygen is insufficient."

甲烷是烷烃中最简单的成员，很容易燃烧，在足够的氧气中生成二氧化碳和水，氧气不充分时生成一氧化碳。

Domesticated animals worldwide are the source of 37 percent of all human-induced methane, with most of that coming from intestinal fermentation of ruminants.

人为所产生的甲烷有37%都出於农养动物，其中大多数都来自反刍动物肠道里的发酵作用。

Breathing in fumes from cleaning fluids and paint removers that contain methylene chloride can also cause CO poisoning.

呼吸在油烟清洗液和油漆移除含有二氯甲烷也可以造成一氧化碳中毒。

The Fourier transform-infrared spectra of the blue ballpoint inks exposed to ultraviolet light were studied. This research discovered that the solvents volatilized rapidest, and then the rate of polymerization and cross-link process of the epoxy resin took second place, and the decomposition of triarylmethane dyes was slower, and alkyd resin was relatively steady.

在紫外光照射下，通过对蓝色圆珠笔字迹色痕FT-IR显微光谱的研究，发现溶剂挥发迅速；其次是环氧树脂的聚合、交联；三苯甲烷染料的分解比较缓慢；而醇酸树脂相对稳定。

By the experimental bench of bluff body flame and under different working orders,the speed in blowing out the flame of methane premixing gas with vapour is measured.

利用钝体稳定火焰实验台，在不同工况下，测量了含水蒸汽的甲烷预混气的火焰吹熄速度。

Under the right circumstances methane can play a key role in prebiotic chemistry -- the chemical reactions considered necessary to form life as we know it.

在合适的条件下，甲烷在生命前化学中起着关键作用，——被认为是形成生命的必要条件的化学反应。

Under the right circumstances methane can play a key role in "prebiotic" chemistry the reactions considered necessary to form carbon-based life.

在适当环境中，甲烷可以在&生命起源前&的反应中扮演关键角色，人们认为，此类化学反应是形成碳基生命的必要步骤。

Using free radical 4-hydroxy-2,2,6,6-tetramethyl-1-piperidinyloxyl as catalyst, the phase transfer catalyzed method of oxidation of anilines to 15 symmetrical azobenzenes with a saturated solution of potassium ferricyanide in 2N aqueous potassium hydroxide and dichloromethane was described for the first time.

用2，2，6，6-四甲基-4-羟基-1-哌啶氮氧自由基为催化剂，芳胺类化合物在饱和铁氰化钾的氢氧化钾溶液和二氯甲烷的两相转移催化下合成了15 个对称取代偶氮苯。

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。
