废气

The aim of the program is to solve the problem mentioned above by means of stratifying EGR in engine cylinder.

本课题采用将再循环废气与新鲜混合气分层的方法，就是针对上述难题而进行的。

Lignin reticulated polyurethane would be used as a filling in biological sulfureted hydrogen treatment, which was not only a fit medium for bacteria but also a merchandise.

木质素聚氨酯泡沫塑料是一种既适合微生物生长又易于商品化的处理硫化氢废气用填料，这种新用途在国内外尚未见报道。

In this paper,the advanced technologies in diesel engine,including supercharging,EGR and common rail fuel supply were applied to dimethyl ether engine.The engine performance was investigated in various operating conditions.

将柴油机增压技术、废气再循环技术、共轨式燃料喷射技术应用于二甲醚发动机，探讨了在各种技术条件下发动机的排放性能、动力性和经济性。

Maybe there are not so many trashes in this town so that there is unnecessary to collect twice a week.

尽管作者说了EZ一周两次ABC一周一次，但未交代两者每次清理垃圾的数量，如果事实证明ABC公司每次都派出20辆垃圾车，一周一次就打扫的很干净，而EZ每次只派出5辆垃圾车，尽管一周两次垃圾仍清理的不干净，那么作者观点可信度将大大降低（2）即便两者清理质量相同，考虑到清理垃圾时产生的废气、噪音等负面效果，那么ABC的一周一次是不是对居民打扰更少？

First, we need to reduce emissions, this can protect the air around us.

第一，我们要减少各种废气的排放，这样可以保护我们身边的空气。

In these several years, the company has cooperated with German Lurgi and Nanjing Chermical Industrial Group Design Institute to develop the series of products of waste heat boiler of sulfuric acid made of pyrites. This product and blowing air waste heat boiler are selected as Specially-designated Products. Regarding the cement kiln low temperature waste heat recovery, the company has fully introduced and digested advanced domestic and foreign technologies and has achieved great success. The company has marched into metallurgical industry in 2004, established cooperation with numerous large scale metallurgical institutes and successful developed series of products of waste heat boilers in metallurgical industry, especially sinter cooler low temperature waste gas residual heat power generation boiler. It has successively developed the products such as converter waste heat boiler, electric furnace waste boiler etc.

近几年，公司与德国鲁奇、南化设计院合作研制开发了硫铁矿制酸余热锅炉系列产品，该产品与吹风气余热锅炉被《化工工程建设标准》选为定点产品；在建材行业水泥窑低温余热回收上，充分引进消化国内外先进技术，并取得骄人成绩，2004年进军冶金行业，与国内众多大型冶金院建立了合作，成功开发了冶金行业余热锅炉系列产品，特别是烧结冷却机低温废气余热发电锅炉，又相继开发了转炉余热锅炉、电炉余热锅炉等产品。

It keeps exhaust gases from entering the air injection system.

它阻止废气进入喷气系统。

Based on the technology of exhaust gas recirculation, a new method for increasing thermal efficiency of a diesel hot air stove from a greenhouse was proposed.

针对目前使用的温室柴油热风炉存在的热利用率低和排放污染问题，提出了利用废气再循环技术来提高柴油热风炉热效率的方法，并研制出一种适用于温室内应用的全数字式智能监控柴油热风炉 EGR热交换设备，并阐明了其结构及工作原理。

Many factories and commercial activities produce air-borne emissions.

很多工厂和商业活动排放废气。

The absorbent used is a normalized acid solution and the back-titrate is standard alkalescent solution.

因此对废气冷凝吸收液选用先以定量标准酸吸收，再用标准碱回滴的分析方法。

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.

交际能力和语法的关系应该是目标与途径的关系。
