尾气

Some of researchers have proven that the emission of transports is the most serious pollution sources of cities.

一些研究人员已经证明汽车尾气是城市最严重的污染源。

The status of VCM and acetylene gas recovery by pressure swing adsorption in vinyl chloride production units were introduced.

介绍了在氯乙烯生产装置中，采用变压吸附工艺回收精馏尾气中的VCM和乙炔气的情况。

00M . Copper xiangguang of the project is a 200,000 tons of cathode copper, sulfuric acid gas chimney works, the diameter of the chimney on the extraoral 6.120m, outside the mouth of a diameter of 9.983m, chimney height of 97.00m.

The distillated condensate of furnace gas showed that NH3 cleaning efficiency will reach to 98% and the recovery rate of CO2 reach to 30% while adoptingMl asabsorber, CO2 in tail gas recovered for carbonation-soda ash production, then ammonia and CO2 are recovered; the condensation of ammonia in waste water is lower than 0.5tt, CO2 is below 0.03tt, so it can be used directly as soft water, then it has decreased the total quantity of various water containing ammonia in soda ash making system and improved environment.

蒸馏炉气冷凝液表明，以M I作为吸收剂，NH_3的净氨率达到98％，CO_2回收率达到30％，尾气中的CO_2再用于碳化制碱，氨和二氧化碳得到回收利用；废淡液中氨的浓度低于0.5tt，CO_2低于0.03tt，可直接作为软水使用，降低了含氨杂水的总量，使纯碱系统不再多余含氨杂水，改善了环境。

I thought, only carbon dioxide, car exhaust, coal combustion emissions of these will be, did not expect the weak everywhere in life,"carbon" in violation of our lives and our planet.

我本来以为，二氧化碳只有汽车尾气、煤炭燃烧这些会排放，没想到生活中处处都有微弱的&碳&在侵害着我们大家的生活和地球。

Coal combustion type air pollution is the major type of air pollution. However, in some large cities of China, air pollution has gradually changed from the conventional coal combustion type to the mixed coal combustion/motor vehicle emission type.

从全国范围看，我国的大气污染类型以煤烟型为主；在部分大中城市，大气污染类型已由单纯的煤烟型污染向煤烟污染和机动车尾气混合型发展，构成双重负担。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
