尾气

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。

At present, three-way catalyst is widely used to purify vehicle exhaust.

目前，主要是采用三效催化剂对机动车尾气进行净化。

NGV has great advantages on mitigating the risk of being short of energy, reducing tail gas emission from automobiles and playing important roles in protecting environment, but the amount of NOx is still troublesomely high in fact.

天然气汽车在缓解能源短缺、降低汽车尾气污染和保护环境等方面具有较大的优越性，但其NOx的排放量仍然较高。

In a turboprop engine, the main thrust comes from the propeller and only a small proportion from the jet exhaust.

在涡桨发动机中，主要的推力来自螺旋桨，只有一小部分来自喷出的尾气。

Second, the human activities that are causing the temperature rise --- such as burning of coal, oil, and wood and the release of other trace gases --- are fundamental to the world economy.

其次，人类自身的活动会造成气温升高------例如，煤炭、石油和木材的燃烧，以及其它尾气的排放------虽然这些活动对于世界经济发展来说是基础性的。

According to the thesis research, MDPF (Metallic Diesel Particulate Filter), metallic alveolate substrate for diesel oxidizer catalyst, petrolic engine three way catalyst and motorcycle catalyst are produced.

通过论文的研究，分别制备了应用于MDPF(Metallic Diesel ParticulateFilter)、柴油机金属蜂窝载体氧化催化剂、汽油车金属蜂窝载体三效催化剂、摩托车尾气净化催化剂，并进行了初步的应用研究。

Under these best conditions,at aspace tower velocity of 0.3m/s and after two steps'absorption,the con-centration of NO_x can be reduced from 2000ppm～11000ppm to 250ppm～600ppm and NO_x-removal efficiency reaches 90%～94.5%.

理论和实践都证明，NO除生成络合物外，在水中或碱液中都几乎不被吸收。为了有效地吸收NO二，需保证尾气中NO二的氧化度达50%~60%。

The developping trend is discussed assumably in the end. The pollution of automobile epilogue has been doing bad harm to our living space step by step.

展趋势。汽车尾气中的有害物造成的污染，给人类赖以生存的大气环境带来了越来越严重的危害。

The user of dynamic calciner:1. Taiwan Luchang Chemical Corporation ltd.Taiwan Luchang Co.

在对预煅烧物料预热和脱水的同时，使尾气排放时的温度降低、有效利用能源。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
