异辛烷

Addition of small amount of inert solution, such as, pentane and isooctane, to the bulk polymerization system is helpful to remove the reaction heat.

向本体聚合体系中加入少量溶剂如戊烷、异辛烷有助于改善这一问题，使反应平稳地进行。

The experimental results indicated that under the steady operating conditions, the ignition timing of the base fuel (PRF90-90% iso-octane+10% n- heptane), which is equivalent to RON 90, delayed and the peak value of the heat release rate was low compared to the base fuel with single additive (Ditert-butyl peroxide-DTBP, Dicumyl peroxide-DCP, Tert-butyl hydroperoxide-TBHP, Tert-butyl cumyl peroxide -TBCP or Cumene hydroperoxide-CPO) which advanced ignition timing and increased the peak of the heat release rate obviously.

试验结果分析表明，在HCCI发动机燃烧稳定工况下，没有添加剂的基础燃料记作PRF90(为90%异辛烷与10%正庚烷的混合，相当于90号汽油)着火滞后，燃烧放热率峰值低，而混有单一添加剂(Ditert-butyl peroxide-DTBP、Dicumyl peroxide-DCP、Tert-butyl hydroperoxide-TBHP、Tert-butyl cumyl peroxide-TBCP或Cumene hydroperoxide-CPO)的基础燃料则着火明显提前，燃烧放热峰值升高。

In order to analyze the thermal cracking products of fuels, we set up a GC analytical system. The gas products, which comprise methane, ethane, ethylene, propane, propylene and other gases, were collected and analyzed by gas chromatography provided with a flame ionization detector . We calculate the theoretical heat sink of n-heptane at the temperature of 600℃ and 800℃. The theoretical heat sink calculation of iso-octane at 700℃ is also related.

建立了用于分析裂解产物的气相色谱分析系统，解决了本研究中对气态裂解产物的分析要求，特别是气态小分子饱和烃和不饱和烃的有效分离；并根据裂解产物的组成及其生成热数据，对正庚烷在600℃和800℃，异辛烷在700℃时裂解的热沉进行了理论计算。

The combustion characteristics of iso-octane/diesel and ethanol/bio-diesel both show a two-stage heat release without HCCI low temperature reactions.

本文首先采用双燃料的方式，对正庚烷/柴油、异辛烷/柴油、乙醇/生物柴油这三种双燃料组合的HCCI/DI分层复合燃烧与排放特性进行深入研究和比较分析。

A new method of fuel design to control HCCI combustion was given. n-heptane/iso-octane was controlled real-time on a single-cylinder HCCI combustion engine. The test result shows that the equivalence ratio of n-heptane in mixture decides the HCCI ignition and controls the combustion phase of HCCI.

根据燃料设计的思想，提出了混合燃料比例实时优化的均质充量压缩着火燃烧控制新方法，并在HCCI单缸发动机上进行了HCCI异辛烷／正庚烷实时控制试验。

Experiments were carried out on a HCCI platform to evaluate the effects of cetane number and octane number on the HCCI combustion characteristics and emissions using n-heptane, RON25, RON50, RON75, RON90, and iso-octane.

进一步在发动机上对正庚烷、RON25、RON50、RON75、RON90和异辛烷在不同负荷下的HCCI燃烧特性和排放特性进行了试验研究。

Results showed that fat simulants n-hexane and isooctane can be used as a rapid compliance test.

结果表明：用正己烷和异辛烷作为脂肪食品模拟物时，可以大大缩短迁移试验时间。

The temperature accelerated the migration rate and affected on the distribution ratio of Irgafos 168 between HDPE film and fatty food simulants .

The high selective resolution system was constructed with the mixture of isooctane with octanol acting as reaction medium and octanol as acyl acceptor.

建立了异辛烷／正辛醇的混合溶剂为反应介质、正辛醇为酰基受体的高度选择性的酯化拆分体系，并利用水合盐缓冲技术使反应过程中水活度保持恒定。

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。
