查询词典 gas carbon

In the early 1920s, Franz Fischer and Hans Tropsch patented a process to produce a mixture of alcohols, aldehydes, fatty acids and hydrocarbons known as synthol, from a synthesis gas of hydrogen and carbon monoxide.

在1920年代初，弗菲舍尔和汉斯tropsch专利一个过程产生多种醇类，醛类脂肪酸和碳氢化合物称为synthol ，从合成气中的氢和一氧化碳。

In the early 1920s, Franz Fischer and Hans Tropsch patented a process to produce a mixture of alcohols, aldehydes, fatty acids and hydrocarbons known as synthol, from a synthesis gas of hydrogen and carbon monoxide.

乙醛，和碳氢化合物组成的。F-T工艺是间接煤液化的基础。因为通过蒸馏和氧气的气化作用，煤结构被完全分解成合成气，所以此工艺是间接的。然后这些气体通过适当的F-T催化剂的作用，大部分形成蜡油状的碳氢化合物，分子亮分布较宽。wjk678 发布在翻译例文|发布时间： 12：20PM Apr 23， 2008 |评论

The type and concentration of thiophenic sulfur in gasoline and diesel fuel were determined separately by gas chromatography with a sulfur chemiluminescence detector.With activated carbon and 30％aqueous solution of H2O2 as catalyst and oxidant respectively, the experimental studies of oxidative desulfurization of gasoline and diesel were carried out.

采用气相色谱-硫化学发光检测器分析了汽油和柴油中噻吩类硫化物的分布及浓度；以活性炭作为催化剂，以30％过氧化氢溶液为氧化剂，在甲酸存在条件下考察了汽油和柴油中噻吩类硫化物催化氧化脱除的选择性，讨论了硫化物中硫原子电子密度对硫化物氧化选择性的影响。

After th thermal treatment at 2050,the amount of the free carbon and pore decreased .Also .another cause for the unfully conversion of C into SiC was the gas pressure .larger than the capillary force.

含残留C、气孔相的材料进行高温(2050℃)热处理后，材料中残留C、气孔相的含量大大减少。

Because plants sop up carbon dioxide, running cars on ethanol produced from corn or other plants could slow down the rise in atmospheric leels of this greenhouse-warming gas.

植物释放二氧化碳，而由谷物或其他植物的制造的酒精为燃料的汽车能够降低大气中能造成温室效应的气体的含量。

The interfaces electric circuit and the control program can be transplantated to other micro voltage control equipment very easily.Then we take the C_2H_5Br and the hydrogen (H_2) as the source gas to deposite the gradient bromating amorphous hydrogenated carbon film in the improved low-pressure plasma polymerization unit.

然后在改进的低压等离子体聚合装置中以溴乙烷(C_2H_5Br)和氢气(H_2)为源气体沉积了掺溴非晶碳氢薄膜和梯度掺溴非晶碳氢薄膜，用Perkinelmer Lambda12型紫外／可见分光光谱仪测量了样品的透光谱，并利用透光谱计算了薄膜的光学厚度和光学带隙：利用NICOLET MX—1E傅立叶变换红外光谱仪和XSAM800型X射线光电子能谱仪分析了薄膜的化学键和结合态以及薄膜中氧碳元素比和溴碳元素比。

The main intermediates were detected during decomposition,such as acetic acid,oxalic acid,malonic acid,phenol,3-hydroxyhypnone,naphthalene,benzene sulfonic acid,phthalic acid,β-naphthalene etc . by ultraviolet-visiblespectroscopy,ion chromatographand gas chromatograph coupled with mass spectrophotometertechniques.The possible degradation pathway of Acid Orange Ⅱ was also speculated,that was,hydroxyl radical reacted with the azo linkage-bearing carbon of naphthol-ring,and the C—N cleaved,the azo-dye decolored and mineralized.

运用紫外光谱、离子色谱、色谱-质谱联用等方法，测定出酸性橙Ⅱ的主要降解产物有乙酸、乙二酸、丙二酸、苯酚、3-羟基苯乙酮、萘、苯磺酸、邻苯二甲酸、β-萘酚等，并依此推测酸性橙Ⅱ的降解机理，即羟基自由基攻击酸性橙Ⅱ分子上与萘环相连的C—N键，导致C—N键的断裂，进而染料脱色矿化。

It is a weak base and dissociates into water and carbon dioxide gas as it dissolves in the presence of hydrogen ions.

它是一种弱碱，当溶解在存有氢离子的溶剂中时即分解为水和二氧化碳气体。

It is a weak base and dissociates into water and carbon dioxide gas as it dissolve s in the presence of hydrogen ions.
