3 KPa for the system of n-butyl mercaptan and octane was measured by a vapor-liquid equilibrium autoclave.

利用双循环汽液平衡釜测定101.3kPa下噻吩-正辛烷体系的汽液相平衡数据。

The gasoline sample and water can be emulsified directly and nebulized in an ultrasonic nebulizer and the aerosol produced was introduced to flame.

用火焰原子吸收光谱法测定汽油中铅含量是由Robinson首先提出的，以异辛烷稀释汽油，用四乙基铅标准进行测定。

Their catalytic properties for theoxidation of octane were studied by using oxygen as the oxidant.

考察了在氧气作氧化剂的情况下，辛烷在这些杂原子分子筛上的氧化反应行为。

Make sure the fuel octane is high enough for the engines requirements.

确定是否使用的辛烷燃料合适。

In recent papers [14,15] good activity and selectivity in the epoxidation of limonene, cyclohexene, 1-octene and pinene by anhydrous and aqueous H2O2 catalyzed by alumina were reported.

近年来，用氧化铝催化的，用无水的和含水的H2O2将莱烯、环己烯、1－辛烷和蒎烯环氧化中良好的活性和选择性已有报道。

Some relative characters of reverse micro emulsions of reacting substance/AOT/iso-octane were studied. The phase graphs of the reverse micro emulsions at different temperatures were drawn. And the charts of relationship between conductivity of the reverse micro emulsions and the solubility of H2O or the solution of RDX in them were also done. On the base of them as well as characters and rules of preparation of nanometer materials by the method of micro emulsions, the best conditions were found in the preparation of the reverse micro emulsions.

论文摘要本文首先对反应物/AOT/异辛烷微乳液体系进行了研究，得出了该体系在不同温度下的相图和微乳液体系电导率与反应物的增溶量之间关系图，结合纳米材料微乳液制法的原则和特点，确定了微乳液配制的最佳条件。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
