The results showed that the optimum condition for straw anaerobic fementation is the straws was 8cm length and pretreatment with 10% ammonia liquor, inoculation proportion 1:1.5, control the humidity of sludge 91.7%, and the culture temperature 35℃, with supplement of 0.5% urea.

结果表明农作物秸秆厌氧消化产甲烷的适宜条件是：用质量分数10%的氨水预处理，秸秆长度8cm，接种量1：1.5，接种污泥含水率91.7%，反应温度35℃，尿素添加量为秸秆用量的0.5%。

Under catalysis of AlCl3, trans-1-chloro-3-phenyl-1-propen-3-one was first prepared using benzoyl chloride and acetylene in CH2Cl2 at 20~25℃, which the yield is 7% higher than that in CCl4 at 40~45℃.

通过对其反应条件的研究，首次用苯甲酰氯和乙炔在三氯化铝作用下合成出反－3-苯基－1-氯－1-丙烯－3-酮；并发现用二氯甲烷作介质在20~25℃下的反应产率，比用四氯化碳作介质在40~45℃下的反应产率约高7%。

A new organic compound:N,N'-bis(1,10-phenanthroline-2-formacyl)-4,4'-diamino-diphenylmethane was synthesized via oxidation,esterification,substitution,hydrolysis, amidation of 1,10-phenanthroline as the starting material with chemical reagents (hydrogen peroxide,benzoyl chloride,potassium cyanide,sodium hydroxide solution,4,4'-diamino-diphenylmethane).

以邻菲啰啉为起始原料，与双氧水反应合成邻菲啰啉-N-氧化物，接着与苯甲酰氯、氰化钾、NaOH水溶液一一反应合成中间体邻菲啰啉-2-甲酸，再与4，4′-二氨基苯基甲烷进行酰胺化反应合成目标产物。

This failed because the methane crystals, prevalent at such depts, kept melting and expanding within the box, causing the box to float rather than settle.

这种方法也失败了，这是因为甲烷晶体在这样的深度无处不在，在容器里持续融化并扩张，造成容器膨胀，而非稳定下来。

Adding too much chlorine and bromine to disinfect the water can result in creation of potentially harmful trihalomethanes.

但氯加多了，也有可能产生偏高的有害物质－－总三卤甲烷。

The additive of Cu made Co well dispersed on catalyst surface, which suppress the by-reaction of methanation.

Cu组元的加入能够保证Co组元均匀地分散在催化剂的表面，有效地抑制了甲烷化反应的发生，使催化剂具有较好的合成醇性能。

The result shows that the qualities of coke were improved generally if coking experiment was done with preliminary disposed coal in which the percentage of weakly caking coal increases to 45%.

研究结果表明，使用预处理后的煤炼焦可在弱粘煤配比提高到45%以上时仍能全面提高焦炭质量；能显著提高炼焦生产能力、减少焦化废水，并能缩短炼焦时间；炼焦的副产品，焦油中芳香烃明显增加，煤气中氢气增加，甲烷减少。

Catalyst particles coated uniformly on cordierite surface through dipping-method in nickel nitrate solution, were used to synthesize carbon nanotubes via methane diffusion flame method.

借助于硝酸镍溶液，利用浸渍法在堇青石表面均匀负载镍催化剂颗粒，在甲烷扩散火焰中活化并催化生成碳纳米

It can be conclude from gas chromatography that all most of methane oxide to carbon dioxide in the molten salt.

从燃烧产物的气相色谱分析结果可以看出，甲烷在熔融盐中绝大部分被氧化成了CO2和H2O。

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。
