结果表明，随着酸性气中氨含量的增加，硫回收率下降；酸性气中的氨必须在制硫燃烧炉中完全燃烧分解为N2和H2O，否则会形成铵盐结晶而堵塞下游设备，严重时将导致停产；根据酸性气中氨含量的不同，可选择不烧氨和烧氨2种工艺流程。

Its high-capacity and strong-acid-resistance were proved. In the acid condition, the adsorption efficiency to acide green 6B and direct fast yellow RL reached above 90%. Through the adsorption rate curve on adsorption behavior of the three dyes, they were all according with pseudo-secondary adsorption rate curve. The rate constant of adsorption increased with increasing temperature. Through the adsorption isotherm of the three dyes, acide green 6B and direct fast yellow RL were according with Langmuir equation, while disperse blue 56 was according with Freundlich equation. The adsorption behavior was an endothermic process. Entropy was increasing during the adsorption. So raising temperature was in favor of adsorption.

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。
