燃烧中的

There is dehydrogenization reaction during the combustion process leading to sample expansion, which is harmful to the reaction between W and C and unfavorable to the synthesis of uniphase C.

燃烧产物由两种粉末组成：粒径2-4μm，棱角较明显的粗粒度粉末和粒径≤1μm的细粒度粉末；随体系中W含量减少和预热温度的提高，产物粗粒度粉末增加，细粒度粉末减少。

It is worth mentioning that the Fe-Ti-C system of 75wt% Fe content belongs to low exothermal system, the combustion synthesis reaction took place at 734'C under the preset heating rate 1000℃/s based on the electric field, and there were small TiC particles without Fe〓Ti in the products, which also was one of the novelties of this research.

值得一提的是，对于Fe含量高达75wt％的Fe-Ti-C体系实际上属于低放热体系，然而在电场诱导下，当预设升温速度提高至1000℃/s，在743℃时发生了燃烧合成反应，所获的合成产物中TiC颗粒细小，且没有Fe〓Ti相出现。

A method for the determination of phenol and catechol in tobacco leaf by high performance liquid chromatography with methanol and 0.05 mol/L of monopotassium phosphate as mobile phase at a flow rate of 0.5 mL/min was described. Phenol and catechol were extracted from tobacco sample by distillation and solid phase extraction with Sep Park C 18 cartridge.

引 言挥发酚是烟草中一类重要的成分，它在烟草燃烧时直接进入烟气，大多有不好的气味，而且很难被掩盖；特别是苯酚和儿茶酚对呼吸系统有腐蚀作用和助癌作用，近年来逐渐引起了烟草化学工作者的注意〔1〕。

The enhancement of NO oxidation to NO〓 and the suppressing of propene combustion are beneficial to NO selective reduction.

在NO-SCR催化剂研究中，抑制烃类的完全燃烧和提高NO氧化为NO〓的能力，是提高NO选择还原性能的有效途径。

It continues through the great spiritual master Moses, who led the Jewish people out of bondage in Egypt and spoke to God in the burning bush at Mount sanai, which was a direct revelation of the Godhead.

它继续延伸经过伟大的精神领袖摩西，摩西率领犹太人民脱离了埃及的统治而且在撒拿山上燃烧的矮树丛中跟上帝说话，他是直接揭示了神性。

"Biomass burning" from forest fires, vegetation clearing and fossil fuel was just as much to blame for the shrouding haze as dirty industries from Asia's great cities, the study found.

研究发现，除了亚洲大城市中一些污染环境的工业之外，森林大火、植被清除和燃料燃烧对环境同样造成了严重的污染，因而也是这片亚洲褐云形成的原因之一。

It is considered that these materials are derived from different sources: calcite comes from cigarette paper, whewellite is crystallized during the growth of tobacco leaf itself, and gypsum is formed in the combustion process of cigarette.

这些矿物具有不同的来源：方解石来自卷烟纸，一水草酸钙石是烟叶生长期间自身合成的矿物，石膏是香烟燃烧过程中新形成的矿物。

The autumn garden blazed in bright color and the season's fruit swelled in their trees.

秋天花园在他们的树中被增大的明亮颜色和季节的水果燃烧。

The optimized combustion chamber accelerates the transferring speed of the flame, prevent the deflagrating, even the heat transfer on the piston and lower the amount of the exhausting

优化设计的燃烧室，加快了燃烧过程中火焰的传播速度，有效防止爆燃的产生，使活塞传热更加均匀，排放更低。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
