Methods Eighty Class Ⅱ isogeneic F344 rats, weighing 250-350 g, were randomly divided into 2 groups(n=40). The control group adopted the Strome model. The allograft used for the experimental group preserved ascending pharyngeal artery, which formed a complex allograft together with tongue base, larynx and pharyngolarynx. End-to-end anastomosis was performed between both allograft common carotid arteries and anterior neck veins. The patency rate and survival rate of the allograft of the 2 groups were compared.

Through the research of this paper, a conclusion can be drew: NaCl treatment raise the NH4＋-N removal ratio obviously by 18%, and is better than treating by heating, H2SO4, HCl and NaOH. The most reasonable concentration of NaCl is 0.8~1.0mol/L considering technical, economic and other factors synthetically; The best conditions of NaCl modifying is as follows : temperature 70~75℃, time 2.5hours, granularity ＜120mesh, volume/mass 25ml/g; As additive forming pores, activate carbon powder is a little better than charcoal powder, but the effect of both is much better than sawdust.

通过本论文的研究得出以下结论：NaCl改性能明显提高沸石对氨氮的去除效率，氨氮去除率提高了18%以上，其改性效果优于加热、H2SO4、HCl、NaOH等处理方法，综合考虑技术经济等因素的影响，取0.8～1.0mol/L为最合理的改性浓度；NaCl改性的最佳条件如下：温度70～75℃，时间2.5h，沸石粒径＜120目，体积质量比25ml/g；作为微孔沸石的造孔剂，活性炭粉略优于木炭粉，但二者的效果均比木屑好得多。

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。
