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。

An analytical model was presented to study the cloud expansion during near field regime, and the liquid fuel expanding velocity-radius relation and the liquid breakup model were given. A 2-dimensional axisymmetrical diphasic flow numerical simulation for cloud expansion during far-field regime was carried out, and the distribution parameters of fuel in cloud were given.

对近场阶段云雾的膨胀采用分析模型来研究，给出了这一阶段液体燃料膨胀的速度—半径关系及液体环的破碎规律；对远场阶段云雾的膨胀采用二维轴对称两相流的数值模拟来研究，得出了云雾中燃料的分布状态随时间的变化规律。

Hitherto mankind has relied on fossil fuel for a major part of its energy supply. Obviously the reserve of fossil fuel is by no means unlimited and will eventually be exhausted after decades. Hence, so far as long-term viewpoint is concerned, it is of importance to utilize the abundant and elean solar energy as an alternative energy source. Stimulated by this objective, studies on the preparation of suitable thin semiconductor films of larger size using simpler methods have attracted increasing interests.

从应用角度看，目前人类利用的矿物燃料其储量终究有限，而太阳能广泛存在，作为一种新型的能源，就长远的现点而言，具有巨大的潜力和广阔的前景，近些年来，研究用简单的方法制备大面积的化合物半导体薄膜材料，越来越受到重视，我们采用电沉积的方法在Ni、Ti以及导电玻璃等基底上沉积了多种硫属化合物半导体材料。

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

Pt nano particles decorated with nafion ionomers were synthesized and used as electrocatalyst in proton exchange membrane fuel celldue to plentiful proton channels provided by the enwrapping polymers.Then decorated Pt particles were deposited on carbon nanotubes,which enwind each other into interconnect nets and form the framework of the catalyst layer for PEM fuel cell.

介绍了Nafion聚合物作为修饰离子，合成具有原位质子导电能力的纳米Pt颗粒；TEM分析显示Pt颗粒的平均粒径为4nm，颗粒之间界限明显，分散状态良好；将这种离子导体修饰的纳米Pt沉积到纳米碳管表面作为质子交换膜燃料电池催化电极，纳米碳管相互缠绕在催化层形成交联的电子通道。

The test device can eradiate the far-infrared rays between 4μm ~ 14μm in 47℃~80℃. After a series of contrast tests, it shows that the fuel consumption is remarkably decreased. The mean fuel consumption is decreased by 3.9% when the car is running on the limited road, or it's decreased by 8.6% when the car is running on the variable status road. Th...

经过一系列对比试验后表明，在47℃~80℃温度环境下发射的波长为4μm~14μm的远红外线对汽车燃油经济性有较显著的影响(汽油车在限定条件下的平均燃油消耗量减少3.9%；汽油车多工况燃油消耗量减少8.6%)，对其他性能也有一定的改善。

It has been discovered that the higher percent of explosible fuel gas in the leaked is, the more heat of combustion is, and the more quantity of fuel leaked into the atmosphere is, the larger damage radiuses is.

通过计算发现，相同条件下，参与爆炸的燃料占泄漏燃料的比例越高，燃料的燃烧热越大，泄漏到空气中的燃料质量越多，破坏半径就会越大。

A number of Europe's major carmakers used this week's Geneva Motor Show to unveil new concepts combining the frugalness of a compact diesel engine with the fuel-saving capability of a hybrid electric drivetrain. Some of the concepts, such as Volkswagen's new TDI Hybrid, return fuel-economy of close to 70mpg (3.35L/100km).
