采用溶胀悬浮接枝共聚法，将水溶性单体丙烯酸、丙烯酰胺接枝到疏水性氯化聚乙烯大分子链上，合成双亲性接枝共聚物。

In chapter four, molecular imprinting polymers against amino acid derivatives utilizing 2-VP+AM as combined functional monomer and trimethylolpropane trimethacrylate as tribasic cross-linker were prepared and result was compared with those with the same amino acid derivative as the imprinted molecules utilizing ethyleneglycol dimethacrylate as dibasic cross-linker. It was found that cross-link intensity of the molecular imprinting polymer is higher when TRIM was utilized and baseline separation for the imprinted molecule could be achieved. When TRIM was utilized as cross-linker more molecule is imprinted during the polymerization.

第四章采用2-乙烯基吡啶+丙烯酰胺复合功能单体，考察了三元交联剂三甲氧基丙烷三甲基丙烯酸酯烙印氨基酸衍生物的情况，并与二元交联剂乙二醇二甲基丙烯酸酯烙印相同氨基酸衍生物的情况进行了对比，发现三甲氧基丙烷三甲基丙烯酸酯交联剂在较小的用量下就可使分子烙印聚合物达到足够的交联度，实现烙印分子的基线分离。

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.
