甲烷

Optimization technology was acetidin: N-hexane (3:7) as low-pole solvent system, methanol: dichloromethane (1:9) as polar solvent system, 20% glycerol filter paper as moisturizer, 14 h age Bacillus subtilis as indicating strain seed on thin layer plate cultivated for 14~18 h, 1% TTC staining time 1~2 h, bacterial mix method suitable to 0.2%~0.6% agar semisolid bouillon culture-medium, bacterial spread method suitable to 1% agar semisolid bouillon culture-medium.

结果：该方法展开系统筛选简单，抑菌斑位置准确、斑点清晰，其优化条件为：以乙酸乙酯：正己烷(3：7)为弱极性展开系统，甲醇：二氯甲烷(1：9)为强极性展开系统，用20%甘油滤纸对湿室保湿，以14h菌龄的枯草芽孢杆菌为指示菌种子液，自显影薄层板36℃培养14~18h，1%TTC显色时间为1~2h，含0.2%~0.6%琼脂的半固体肉汤培养基应使用混菌法生物自显影，含1%琼脂半固体肉汤培养基应使用涂布法生物自显影。

The humic acid was used as the precursors of trihalomethanes, the overall reaction order is second-order.

以腐殖酸为三卤甲烷形成的前驱物质，确定THM 生成的反应级数为二级。

Makes use of gas sensor,it can measure strength of five kinds of gas which include O2、CO、CO2、H2S and CH4 at the same time, it have also alarm and display and print etc function,far-ranging applied in environment monitor, hygiene epidemic prevention, labor protection, combustible and explosive, safety to produce etc. it have certain applied value.

利用电化学传感器和红外气体传感器，可同时检测氧气、一氧化碳、二氧化碳、硫化氢、甲烷等5种气体在空气中的含量，并具有超限报警、显示、打印等功能，可广泛应用于环境监测、卫生防疫、劳动保护、易燃易爆和安全生产等领域，具有一定的应用价值。

The relationship between CH4 production and input COD load in the NBLM and BLM was further analyzed statistically.

关系甲烷的生产和投入， COD负荷在nblm和博莱霉素是进一步统计分析。

From day 151 onwards, the CH4 concentrations in the NBLM and BLM were below detection limit.

从第一天151起，将甲烷浓度在nblm和博莱霉素均低于检出限。

Thus, the methane produced by the NBL and BL were only collected from the NBLM and BLM, respectively.

因此，甲烷所产生的nbl和BL只收集到nblm和国土管理局分别。

Organic molecules – in the form of methane – have been detected on a planet outside our solar system for the first time.

研究人员首次发现，有机分子以甲烷的形式存在于太阳系以外的一颗行星上。

Goods which are covered or packaged with impervious materials like plastic, aluminium foil, tarred or waxed paper must be opened, cut or removed to allow penetration of the methyl bromide.

对于一些用不透气的材料(如塑料、铝箔、油纸或蜡纸)包装的货物，熏蒸前应切开或除去包装，以使溴甲烷能够充分穿透货物。

Aerobic thermophilic bacteria were capable of oxidizing oil with formation of biomass, the products of partial oxidation of oil, and surfactants.

产甲烷菌在油氧化菌液体培养基中产生CH4， CO2为好氧微生物和厌氧微生物的共同代谢产物。

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.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
