查询词典 octane rating

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。

The interfacial polarization resistances were unvaried during this period,suggested that the SDC modified anode was stable for the direct utilization of octane,and slight degeneration in the performance was associated mainly with the loss of OCV,which was possibly derived from a little carbon deposition within the SDC-coated anode where the level is so low that it almost has no effect to cause severe damage to the anode. The fuel composition and operation conditions had remarkably influence on the cell durability,implied that the stability of the fuel cells could be further improved by varying the iso-octane/O2 ratio and conducting a continuous operation.

燃料组分和测试条件对电池稳定性有着较大影响，说明通过改善O2/iso-octane比例以及维持电池在更长时间内放电能够获得更好的长期输出性能。

Attempts have been done to increase the value of light naphtha isomerizes RON 60 to 70's light naphtha into RON 83 to 90's higher Octane number light naphtha to blend RON 95, or 98 higher Octane gasolines.

本研究为提高轻石油脑的应用价值，应用轻油异构化工场将辛烷值只有60~70的轻石油脑提升至83~90，成为掺配95和98高辛烷值汽油重要轻质油料之一。

The results of n-octane and methylcyclohexane oxidations showed that the C-C bond in n-octane broke more easily than that in cyclohexane under reaction condition.

不同分子结构的烷烃氧化反应结果表明，正辛烷中的C-C键相比于环己烷中C-C键，更容易断裂。

The octane number of 5 substances were predicted using the new methods.The results show that the second level group contribution method exhibits significant improvements in accuracy and should be used for estimating the octane number of branched and ring hydrocarbons.In cases of simple straight chain bydrocarbons, however,the first level group contribution method should be used.

用新方法对未参加回归的五种物质的辛烷值进行了预测，结果表明对于含有支链和环的烃应采用第二水平基团法估算其辛烷值，对简单的直链烃采用第一水平基团法估算其辛烷值。

An alternative increasingly being used is ethanol, which has an octane rating of 108 or 110; gasoline with 10 percent ethanol is marketed as gasohol.

还有一种逐渐普及的替代方案是乙醇，乙醇的辛烷值为108或110，添加10%乙醇的汽油在市场上称为「酒精汽油」。

The exceptional purity of the n-heptane distilled from Jeffrey Pine resin, unmixed with other isomers of heptane , led to its being used as the defining zero point on the octane rating scale of petrol quality.

还含有溶解在萜烯中的不挥发的黏性固体，所以当树脂暴露在空气中，萜烯类物质挥发掉，使得树脂黏度增大，形成固体。

The determination method of gasoline rating units is the only reliable method to measuring octane number of gasoline.

汽油辛烷值发动机引法法测定法是目前唯一可靠的辛烷值测定法。

Another problem is that existing petrol engines cannot take advantage of the much higher octane rating.

另外一个问题是现有的汽油引擎无法利用更高辛烷值的优势。

Biogas has an octane rating of between 120 and 140 which means a lot more motive power than your average premium pump gas.

沼气具有辛烷值在120和140这意味着更多的动力比您的平均溢价泵气。
