甲烷

Focusing on the characteristics of methane, namely its advantages and disadvantages as a liquid propellant.

重点论述了甲烷的特点及它用作液体燃料的优缺点。

In recent years,more and more attentions have been paied to methane activation and conversion by low-temperature plasmas.

近年来利用低温等离子体技术对甲烷的活化与转化研究引起了人们越来越多的关注。

Hodgins interrupts, he's found triphenylmethane dye and iron sulfate in the manubrium and the flesh.

Hodgins中断，他在骨柄和肌肉里发现了三苯甲烷染料和硫酸铁。

Any of various liquid isomers, C10H22, of the methane series.

Nitrogen oxides emission from a series of turbulent methane jet non-premixed flames with different Reynolds number was numerically simulated, in order to investigate the influence of turbulence on the formation of nitrogen oxides.

对一系列具有不同Reynolds数的湍流甲烷射流扩散火焰中氮氧化物的排放进行了数值模拟，以考察湍流对氮氧化物排放的影响。

The first four members of the series (methane, ethane, propane, butane) are gases at ordinary temperatures; the next eleven are liquids, and form the main constituents of paraffin oil; the higher members are solids.

最前的四个烷烃化合物(甲烷、乙烷、丙烷、丁烷)在常温下为气体；接下来的十一个为液体，是构成石蜡油的主要物质；更高碳数的则为固体。

This method also provides a new way of utilization of methane and natural gas.

这个方法也为甲烷和天然气的直接利用提供了一个新的途径。

So far the amount of methane is too small to have a significant impact on the Earth's temperature.

目前，释放的甲烷气体的量还很小，对地球的温度没有太大的影响。

But there are a number of places this methane could be coming from, she said.

但她说，这些甲烷也许有其他的来源。

The chief source of methane is natural gas, but it can also be produced from coal.

甲烷的主要来源是天然气，但也可以用煤来生产。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
