查询词典 methane

The results show that coal and gangue are involved in the microbial role; the quantity of inoculums is directly related to the quantities of gas and the contents of methane, at the same time it has a certain degree of impact on the contents of NO(superscript - subscript 3)-N, NH(superscript + subscript 4)-N, S(superscript 2-), SO(superscript 2- subscript 4), and metals; moreover, because of the microbial anaerobic fermentation, the contents of NH(superscript + subscript 3) are seriously substandard; overall, the group B which has a smaller proportion of gangue has a less impact to the environment compared to the group A which has a larger proportion of gangue.

结果表明：煤、煤矸石参与了微生物作用；接种物的加入量与产气量和甲烷含量密切相关，并对硝酸盐氮、氨氮、硫化物、硫酸盐和金属也有一定程度的影响；同时由于微生物厌氧发酵的关系，氨氮严重超标；矸石比例较小的B组对环境的影响略小于矸石比例较大的A组。

In order to analyze the thermal cracking products of fuels, we set up a GC analytical system. The gas products, which comprise methane, ethane, ethylene, propane, propylene and other gases, were collected and analyzed by gas chromatography provided with a flame ionization detector .
