Studies indicate that while providing detergency at intake valves the detergents at the same time increased CCD to various extent. Comparing to regular gasoline, gasohol is more likely to form deposits at intake valves and combustion chamber and therefore needs more effective detergents.

研究发现有效的汽油清净剂在对进气阀起到清净作用的同时，均不同程度的增加了燃烧室的沉积物，这说明我国汽油清净剂的使用状况仅处于第三代汽油清净剂的发展水平上；乙醇汽油与普通汽油相比，更容易在进气阀与燃烧室内生成沉积物，因此更需要加入有效的汽油清净剂。

Objective Widespread used as gasoline oxygenate additives, methyl t-butyl ether were added to gasoline to enhance the octane number, reduce carbon monoxide in exhausts and to substitute for tetraethyl lead as an anti-knock agent.starting in the winter of 1992, MTBEup to 15wt.

研究目的甲基叔丁基醚(Methyl Tert-Butyl Ether，MTBE)是一种新型的汽油添加剂，主要用来增加汽油辛烷值，提高汽油燃烧效率，减少汽车尾气中一氧化碳等有害物质的排放，并代替四乙基铅用作汽油防爆剂。

Through comparison of energy inputs in corn fuel ethanol life cycle,fossil energy inputs of corn production and ethanol conversion processes were identified as the most important,and therefore nitrogen fertilizer,electivity and diesel used in corn farming and energy consumption of distillation and dehydration process in ethanol production could be known as the most influential factors for the energy benefit of corn fuel ethanol.

但是玉米燃料乙醇从原料的生产、乙醇的转化，一直到被燃耗的整个生命周期中的多个阶段需要直接或间接地消耗矿物能源，因而，虽然玉米燃料乙醇是可再生能源，然而是否具有可持续性及可持续性的大小则取决于其燃耗中所产生的能量与燃料乙醇整个生命周期中所消耗的能量相比是否有盈余及盈余的大小。20世纪70年代中期，玉米燃料乙醇的能量平衡问题研究首次在美国出现[2，3]，当时乙醇替代汽油的能量效益的有关研究指

It was found that more branch-2 olefin and C5~C6 isoparaffin molecules existed in MIP naphtha. The cause of MIP naphtha having higher octane number and less octane loss during hydrotreating could be explained by the octane model of C6 hydrocarbons quantitatively.

通过对MIP和FCC汽油组成分析，发现MIP汽油组成含有较多的多支链烯烃、异戊烷和异己烷，基于碳六烃的辛烷值模型，可以定量地解释MIP汽油辛烷值高和加氢MIP汽油辛烷值损失低的原因。

There are times when the outside world intrudes brutally, as when the cost of gasoline goes up or developers cast their eyes on untouched farmland.

外界的侵入有时是很残酷的，当汽油的成本上升的时候或者那些开拓者的眼睛盯上这些未开发的农田的时候。

Systematic research about technology parameters influences on the magnetic properties and microstructure of theses magnets have been done. The better parameters of production have been achieved. They are showed as follows: as-cast alloys with the nominal composition Nd15Fe78-xNbxB7 are prepared by induction-melting under argon atmosphere. As-cast alloys are broken under argon atmosphere and filtered through 40# screen. The coarse grain is ball-milled under 120# avgas for 80 min. The ratio of milling ball and grain is 15:1. Then fine powder is aligned and pressed in a magnet field of 1.5T. The pressure is 80MPa. The green compacts then are shaped by cold isostatic pressing under 280MPa pressure.

We know that Xi Wen Zhang Ailing smell, I am pleased paint and gasoline odor; know she drink tea and eat greasy Shulan objects; know that she rarely buy things, but not stingy about food on top of carved, but also every day snack, and she nursed back to their own Red-billed as the only Green Warbler Colombia; know that she was a little girl, the first time in the newspaper in her words, received a five-yuan, her mother said it was the first writer's fee, it should be doing the Memorial, but she immediately took This is money to buy a lipstick.

我们知道，隰文张爱玲的气味，我很高兴油漆和汽油的气味，知道她喝茶，吃油腻舒兰对象；知道，她很少买东西，但不是上面雕刻的食物吝啬，而且每天的点心，她调养自己的红作为唯一的绿莺哥伦比亚嘴，知道她是一个小女孩，在她第一次报纸的话，收到了5元，她的母亲说，这是第一次稿费，它应该做纪念，但她立即接手，这是金钱买口红。
