空气压缩机

The model was simplified comparing the real one for the purpose of describing the essential form of components, including the screw compressors, engine, air filter, oil-gas separator, fan, aftercooler for compressed air, instrument box, batteries and fuel tank, and also the effect of connection pipe and small size parts on flow field was ignored.

As one of the common facilities in manufacturing enterprises, air compressors are widely used due to their capacity of producing compressed air. However , an authoritative survey shows that air compressor system consumes about 86%of the total energy cost within five years compared with purchase price that only accounts for 8% of total cost. This high volume of energy consummation invisibly increases enterprises' operational cost. However ,within the 90% of the cost for energy, main tenance and repair , 50% can be saved.

压缩机作为制造厂最常用的设备之一，其所产生的廉价适用的压缩空气能源备受许多企业家青睐，据权威机构调查，空气压缩系统在五年的总成本中，运转能源消耗费用占约86％，压缩系统初期购置费用仅占总成本的约8％，其高额的运转能源费用无形中增加了企业运营成本；然而人们却不知道这里占近90％的能源及保养修理费用却是有50％以上是可能不必支付的。

I didn t use CO2 to test the tanks, but rather air-pressure from my compressor ...

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.
