According to The Chinese Academy of Sciences and Geography, the total annual production of manure and night soil could theoretically generate about 130 billion m3 of methane, equivalent to 93 million tonnes of coal; and 80 per cent of industrial wastewater can also be used to produce methane. The number

据中国科学地质研究院测算，每年产生的粪肥和人类粪便理论上总数可以生产大约1300亿m3甲烷，相当于9300万吨标准煤；而且80%的工业废水也可以用来生产甲烷。

Outside the vessel. Firstly, the combustion character of CH.4-Air mixture inside a obturation vessel was analyzed.

首先，分析了甲烷-空气的等容燃烧特性，并且讨论了燃料配比与点火位置因素对等容燃烧产生的影响，同时给出了甲烷-氧气的等容燃烧特性并予以比较。

Abundant, cheap, and clean, methane is used widely as a fuel in homes, commercial establishments, and factories; as a safety measure, it is mixed with trace amounts of an odorant to allow its detection.

甲烷储量丰富，价格便宜，又干净，所以广泛用作家庭、商业设施以及工厂的燃料。作为一种安全措施，在甲烷中掺入痕量的有味气体以便辨识。

When used alone, nepetalactone attracted mosquitoes to the trap of the olfactometer, however, when mixed with human odor or a L-lactic acid dichloromethane solution, nepetalactone inhibited the attractiveness obviously. Nepetalactone exhibited a spatial repellency, but was not an ideal topical repellent. DEET did not have the attractiveness to mosquitoes, and did not exhibit inhibition on L-lactic acid dichloromethane solution too, hut enhanced the attractivity of human odor to mosquitoes.

风洞定向行为测试结果表明，假荆芥内酯单独作用时，对蚊虫有微弱的引诱效果，但在人体气味及二氯甲烷L-乳酸存在时，可显著抑制这些引诱物对蚊虫的引诱效果，是优良的空间驱避剂；DEET对蚊虫无明显的引诱作用，对二氯甲烷L-乳酸溶液引诱剂也无明显的抑制效果，但可显著增强人体气味对蚊虫的引诱性。

The molecule of methyl iodide have been extensively studied in recent years by reason of the photodissociation channels of methyl iodide not only have relations with the objective of developing chemical laser but also have important significance to open out some basic theoretical questions.

过去几十年，碘甲烷是一种被广泛研究的分子，因为碘甲烷的光解通道不仅与研制化学激光的实用目的关系密切，而且对揭示单分子光解过程的一些基本理论问题有很重要的意义。

It was found that the CH_4 absorption was related closely to reaction performance of co-aromatization of methane with propane.

发现在各个催化剂上甲烷的吸附性能和甲烷丙烷共活化反应的性能密切相关。

The influences of temperature and scan rate on the electrochemical characteristics of nitromethane were also investigated by using cyclic voltammetry.

采用循环伏安等测试方法，以铂微盘电极为工作电极，研究了硝基甲烷在离子液体1-正丁基-3-甲基咪唑四氟硼酸盐(BMImBF4)中的电化学行为，并探讨了温度和扫描速率等因素对硝基甲烷电化学特性的影响。

Based on the available data of heat flows, sea-bottom temperatures and geothermal gradients, this paper studied the potential distribution of natural gas hydrates in the South China Sea, and discussed their influential factors.
