摘 要：针对河南某一水硬铝石型氧化铝拜耳法溶出赤泥，采用自制丙烯酰胺-丙烯酸钠-β-衣康酸单甲酯共聚物新型絮凝剂对其进行沉降实验。

In this paper, the action mode of NMA in the traditional polyacrylate emulsions was studied by extracting the traditional self-curable PA latex film before curing and comparing the properties of two kinds of model latices A and B. Where model A was prepared according to the traditional self-curable PA latex and the model B was a blend of polyacrylates emulsion and an aqueous solution of poly-NMA. The total proportions of the ingredients were adjusted just the same as of model A. The influences of monomers, the dosages of crosslinking monomer A and emulsifier etc.

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。
