甲烷

Life generates methane, ammonia, oxygen, hydrogen, carbon dioxide, and many other gases.

生命生产出甲烷、氨气、氧气、氢气、二氧化碳以及其他气体。

For example, researchers of California revealed how some organisms consume methane, converting it to energy and leaving hydrogen and carbon dioxide as byproducts.

例如，在加利福尼亚的研究者揭示了一些有机体怎样消耗甲烷，把它转换成能量并且留下碳水化合物作为副产品。

In addition to water, this study will include the following components: hydrogen sulfide, carbon dioxide, methane, ethane, and propane.

除水外，本研究还包括以下方面：硫化氢、二氧化碳、甲烷、乙烷和丙烷。

"Microbes that produced methane from hydrogen and carbon dioxide were one of the earliest forms of life on Earth," notes Carl Pilcher, Director of the NASA Astrobiology Institute which partially supported the research.

"微生物产生的甲烷，氢气和二氧化碳是最早形式的地球上的生命，"注意到卡尔尔彻主任美国宇航局天体生物学研究所的研究部分支持。

Some of the more common problems include carbon dioxide, ammonia, hydrogen sulfide, and methane.

比较常见的一些问题包括二氧化碳，氨，硫化氢和甲烷。

The way of the formation of methane through CO2/H2 reduced, the main origin of hydrogen elements are from production of anaerobic degradation of organic matter in the role of the hydrogenase with biohydrogen-bacterium.

对于CO2（H2）还原途径形成的甲烷，氢元素主要来源于产氢菌在氢化酶的作用对有机质的厌氧降解。

The higher its concentration, the greater the warming - and, more important still, the greater the chance of triggering something grave and irreversible: rising sea levels due to the melting of Greenland's icecap; runaway release of methane in the tundra.

而二氧化碳的浓度越高，气温就会越高--更重要的是，还可能引发某些更严重、更不可逆转的变化：格陵兰冰盖的融化造成海平面上升；冻土地带的甲烷失去控制释放出来。

Properties White powder, inodorous, non-toxic, soluble in dilute alkali solution, carbon disulfide, benzene, acetone, dichloromethane and a little soluble in chloroform, insoluble in alcohol, carbon tetrachloride and ethyl acetate.

性质 白色粉末。无毒、无味。溶于稀碱、二硫化碳、苯、丙酮和二氯甲烷，微溶于氯仿，难溶于乙醇、四氯化碳、醋酸乙酯。

All are inoffensive as opposed to products of methane, carbon dioxide formed under strictly anaerobic conditions

这些都没有毒性，这与严格地在厌氧条件下形成的甲烷、二氧化碳的情况相反。

Consider to think, although apparent gaseous state is not had in 0 derv of the interfuse in artesian well fluid,hydrocarbon exists, but fall in certain environmental temperature condition, the volatilization with have certain free hydrocarbon composition appears C_(11 the following liquid state volatilizes hydrocarbon , what cause gas to measure complete hydrocarbon thereby is unusual, but the change that this won't cause gas to measure constituent to be worth however, use this one characteristic, can lift with complete hydrocarbon and the method with not elevatory firedamp will distinguish the complete hydrocarbon holiday that mixes fluid of derv artesian well to cause is unusual.

探究认为，虽然钻井液中混入的零号柴油中并无明显的气态烃存在，但在一定的环境温度条件下，将有一定的挥发游离烃成分出现C_(11以后的液态挥发烃，从而引起气测全烃的异常，但这却不会引起气测组分值的变化，利用这一特征，就可以用全烃升高而甲烷不升高的办法来区分混柴油钻井液引起的全烃假异常。

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.
