In order to improve demisting efficiency of mist eliminator in terms of different droplet diameter and reduce blockage of gas gas heater in desulfurization system, numerical simulation and experimental study were carried out on the mist eliminator in bubble desulfurizer.

为提高除雾器对不同粒径小液滴的脱除效果，减轻脱硫系统气气换热器的堵塞程度，对鼓泡脱硫塔除雾器性能进行了数值分析和实验研究。

The results of numerical simulation suggest that the demisting efficiency increases as droplet diameter and gas velocity increasing and decreases as the mist eliminator plate spacing reducing, and the efficiency of arc-shaped plate with barb mist eliminator is higher than that of polyline-shaped plate mist eliminator. Droplet with a diameter under 20 mm is of low demisting efficiency.

数值分析表明：除雾效率随液滴直径的增大而增大，随进气速度的增大而增大，随除雾器叶片间距的增大而降低；带倒钩的弧形板除雾器比折形板除雾器的除雾效率高；粒径小于20 mm的小液滴脱除效率较低。

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.
