Afore-mentioned research are high pure to going out from firedamp depart methane gas has very important sense.

上述探究对从沼气分离出高纯甲烷气具有极为重要的意义。

In general craft,∶ of 2 chloric firedamp ∶ of 35~30 of ∶ of =65 of 3 chloric firedamp 70, their scale can adjust, and 4 chloridize carbon occupies 7%~10% about.

在一般的工艺中，二氯甲烷∶三氯甲烷=65∶35~30∶70，它们的比例是可以调节的，而四氯化碳约占7%~10%。

Methane is inflammable and explosion hazard gas as the basis of mash gas, firedamp and rock gas .

甲烷作为瓦斯、天然气、沼气等的主要成分，是易燃易爆气体。

Based on design of software system, test result indicates the system possesses high sensitivity to tolerance for fog, firedamp, ethane, nocuous air, etc.

测试结果表明，该系统对烟雾、甲烷、乙烷等有害气体具有较高的灵敏度，可用作消防网络的监测与报警。

For the system of industrial test for treatling 200m 3/d wastewater, the removal rate of COD reached to over 90%, and the H 2S in firedamp was finally recovered as the by-product of sulfur.

这些物质在厌氧环境下，通过硫酸还原菌的作用，产生大量硫的还原产物存在于消化液中，一方面引起设备的腐蚀，使水质产生异味；当这些物质在消化器中积累到一定浓度，就对甲烷菌产生严重的抑制作用。

We found that a fermentative bacterium used its flagellum for interaction with a specific methanogenic archaeon.

研究人员发现，发酵性细菌能利用其鞭毛与特定的古甲烷菌产生互作。

Transcriptome analyses showed that a substantial number of genes in the archaeon, including those involved in the methanogenesis pathway, were up-regulated after the contact with the flagellum protein.

转录组分析表明，古细菌中的大量基因，包括那些参与甲烷生成途径的基因，在其与鞭毛蛋白接触后都被进行了上调。

A combustion simulation adopting the Reynolds stress model and the Laminar Flamelet model was performed to determine the effect of humidity in the combustion air on temperature, velocity and NO distributions of methane/air diffusion combustion in a swirl combustor.

采用湍流雷诺应力微分模型和层流小火焰模型，对湿空气透平带旋流器的燃烧室内甲烷扩散燃烧过进行了数值模拟。

Used turbulent flows model,methane/air half-particular chemistry mechanism and laminar flamelet model couple to calculate,and work out that excessive air coefficient is 1.2 and 1.4,where velocity in firebox and mixture,temperature and component in radial.The result indicated...

利用湍流流动模型、甲烷/空气半详细化学反应机理和小火焰模型耦合求解，分别计算出过量空气系数为1.2和1.4的速度在燃烧室内的分布状况以及混合分数、温度和组分的径向分布，模拟结果表明小火焰模型能够用来描述燃烧室内燃烧机理。

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.
