DMEbecomes a potential alternative fuel,for its excellent autoignition performance and capacity to meet ULEV emissions standards for diesel engines without any exhaust gas after-treatment.

由于DME有良好的压燃着火性能以及不需特别的措施就能达到超低排放标准，因而成为柴油发动机一种很有潜力的替代燃料。

The results show that the liftoff height of the CH4/Air jet flame decreases with the increase of the coflow temperature, and the change of the liftoff height versus the coflow temperature presents the twostages behavior, and the stabilization of lifted flame is dominated by the autoignition of premixed homogeneous mixture in lower coflow temperature range. The phenomena of rapid multipoint autoignition were observed in the experiment of diesel fuel spray issuing into the CATA, and a special lifted flame appeared with a triple flame.

结果表明：甲烷气体燃料火焰起升高度随协流温度的升高而降低，呈现出两阶段变化特点，低温段发生了明显的自燃现象，其火焰稳定由均质混合气自燃所主导；柴油液雾燃烧试验观察到了快速的多点自燃现象，形成了独特的起升火焰，有三重火焰的特征。

The invention concerns a burner comprising a premix designed to produce a flammable air-fuel mixture, said burner including a vortex generator, wherein are provided two complementary burner shells forming a passage body, having each a first half-cone burner shell section (1) and delimiting together a turbulence chamber, widening in the axis in the form of a cone, as well as tangential air intake slots in the axial longitudinal direction of the cone.

描述了一种用于产生可点燃的燃料-空气混合物的预混燃烧器，该预混燃烧器具有涡流发生器，该涡流发生器设置了至少两个对穿流本体进行补充的燃烧器壳，所述燃烧器壳分别具有构造为分锥形状的第一燃烧器壳区段(1)并且共同限定着在轴向上按锥形方式扩展的涡流室并且限制着所述沿轴向的锥体纵向伸展方向相互相切的进气缝隙。

Sodium azide is the fuel of choice for a number of reasons. It is a solid propellant with a very high gas generation ratio. It is very stable in this application.

钠叠氮化物被选作燃料是有原因的，它是固体的，能够推进产生气体的发生率，并且在应用中非常稳定。

There should be no problem in obtainingfuel for the Babington burner as most small restaurants struggle to getrid of their waste cooking oil.

不应该有任何问题，在获得燃料巴宾顿燃烧因为大多数小餐馆斗争摆脱废物食用油。

The government has faced backbench calls to impose a windfall tax on energy firms and has been criticised for rejecting plans for a one-off cash payment to householders to help pay for steep increases in fuel bills.

政府所面临的backbench要求强加一种意料之外的税，能源公司，并已受到批评，拒绝计划，以便提供一次过的现金支付住户，以帮助支付陡峭的增加，燃料法案。

The hydrogen fuel and battery gauges are to the right of the H2 ball-shaped meter.

氢燃料电池量表是对氢气球型米的权利。

"All parts of the tree yield products of economic value, being used variously for timber, furniture, basketry, fuel, rope , and packing material."

全株都有经济价值，可用作木材、家具、燃料、绳索和包装材料。

In addition, there is the world's 520,000 bbl / d of bio-fuels production capacity under construction, while the same number of production capacity is being planned, most of which is ethanol.

另外，全球还有52万桶/天的生物燃料产能正在建设之中，同时有相同数量的产能正在计划之中，其中大部分是乙醇。

The comparison with fossil fuels is going to be adverse for virtually all biofuels on cropland.

无论是哪种生物燃料，只要是靠了庄稼地而生产出来的，那么，其环境效益就将总是会比不过石油。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
