Furthermore the performances of heat transfers including corrugate plate, tube and fin-tube were compared under the same conditions. The results show that when the air frontal velocity is between 2.45 and 4.1m/s, the overall heat-transfer coefficient of plate heat exchanger ranges from 100 to 160 W/m^2/ equal to one sixth of that of fin- tube cooler based on tube outside area, which is about 70% higher than that of tube cooler. The volumetric heat transfer capacity of plate cooler is 1.5 times as that of fin-tube cooler and 15 times as that of tube cooler. The heat transfer capacity of per unit power of plate cooler is 5.5 times as that of tube cooler and similar results for fin-tube cooler.

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。
