At the same time, the fouling mechanism of membranes given in this thesis can give a reasonable explanation on the change of membrane performance. Our results show that the magnetization of membranes can effectively improve the anti-fouling ability of the PAN- Fe_3O_4 membrane. The obtained result may give insight to the development of new membranes with a good anti-fouling performance in the filtration of blood solution. No chemical bond was found between PAN and Fe_3O_4 in the membrane at room temperature. The addition of Fe_3O_4 can improve the temperatures of dehydrogenated reaction and decomposition of PAN but dot change the glassy transition temperature. The resistance against acid is stronger than the resistance to base for a PAN- Fe_3O_4 membrane.

结果表明在PAN- Fe_3O_4超滤膜制备过程中使用外加磁场作用能有效提高膜的耐污染能力，这一结果为开发适用于血液处理的耐污染超滤膜提供了一种新途径；在PAN- Fe_3O_4超滤膜中，四氧化三铁与PAN在室温下没有形成化学键，也不存在官能团之间的相互作用；添加Fe_3O_4对膜的玻璃化温度没有影响，但能提高PAN环化脱氢反应的温度和分解温度；PAN- Fe_3O_4超滤膜的耐酸性强于耐碱性，在pH值为10以上的溶液中由于水解作用而溶解，使得膜失去使用价值，膜的耐酸性与酸的种类、浓度和氧化性有关。

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。
