1
Methane (CH4) is the main constituent of natural gas, and is the result of natural decomposition processes.
甲烷（CH4）是天然气的主要成分，是自然分解过程的产物。
2
The results indicate that CNTs grown using CH4 and H2 as reaction gases are bent and hollow, with a large average diameter and a low.
结果表明，用CH_4和H_2为反应气体制备的碳纳米管是弯曲和中空的，它们的直径较大，生长速率较低；
3
While oil poses undeniable ecological risks, methane (CH4) could prove daunting as well.
虽然石油带来无可否认的生态风险，甲烷（CH4）的危害同样可怕。
4
Because CH4 content value is quite different in regional strata in Jiucaiping area, the unified index is adopted to appraise the whole area.
由于九彩坪地区不同区域地层中CH4含量值差别较大，对整个地区采用统一的指标进行评价不尽合理。
5
The CH4 emission before and after cutting in forest wetlands had minor correlation with the water level.
森林湿地采伐前后的甲烷排放与水位相关性不大。
6
The element's sensitive mechanism to CH4 gas is also discussed in the end of this paper.
文章最后对所研制的气敏元件的气敏机理作了论述。
7
Development of the study on methane activation mechanism in recent years have been reviewed in this article.
对近年来CH4活化机理方面的研究做了综述。
8
Natural gas is a combustible gas which major component is CH4, and release heat when burning.
天然气由甲烷CH4为主的可燃气体组成，其燃烧时发出热量。
9
CH4 uptake flux also had obvious diurnal variation, higher in the daytime and lower in night.
CH4吸收通量具有明显的日变化，吸收通量白天高夜晚低。
10
Their catalytic activities in partial oxidation of CH4 were studied.
研究了催化剂催化CH4部分氧化反应的活性。
11
CH4 production and its effect on the forest carbon cycling.
CH4生成及对森林碳循环的影响方面的研究。
12
The key of controlling CH4 emission lies in regulating irrigation water.
控制稻田甲烷排放的关键在于调节灌溉水。
13
From the calculations, we conclude that the C-addition path is the most favorable and the major products are HCN, CH4 and C2H6.
由计算可以得出，碳加成通道是能量上最有利的，主要产物是HCN，CH4和C2H6。
14
The emission of CH4 and N2O increased basically with acidification cumulation degree.
CH4和N2O的排放基本上随酸化累积程度的加深而增加。
15
methane(ch 4 ) has both natural and anthropogenic sources.
甲烷（ch4）具有自然和人为来源。
16
the CH4 mixing ratio decreases from low latitude to high latitude.
甲烷混合比自低纬向高纬递减。
17
It is estimated that some 50 billion tons of CH4 could be trapped in the Siberian Lake permafrost.
据估计，可能约有500亿吨甲烷被困在西伯利亚湖永久冻土中。
18
CH4 content declined with the increase of temperature, residence time and heating rate.
CH4含量随着温度的升高、停留时间的延长、升温速率的下降而下降。
19
and CH4, which is a new energy generated by methanogens from CO2, is the beneficial complement of the energy.
产甲烷菌具有利用CO2生成CH4的能力，新生成的CH4成为能源储备的有益补充。
20
But a large proportion of global greenhouse gas emissions are actually other gases, such as N2O (nitrous oxide) and CH4 (methane).
但是，全球温室气体排放实际上有相当一部分是其他气体，如N2O（一氧化二氮）和CH4（甲烷）。
