Secondly,UV spectrophotometry was adopted to research the combination action on SM_2 and SIZ with MAA and 4-Vp.The combination action of functional monomer with template molecules were produced in the results. Then,the prediction imprinting principle of SM_2 and SIZ were given. The diagrams of infrared spectrum were analysed in MAA and 4-Vp and IMPs of SM_2. It was discoved that the absorbability peak of C=C function group in the IMPs were turn to be very low ,but the function group of carboxylic acid and pyridyl in the IMPs were no evidence change, and the condition was created in the molecular recognition of MIPs. Thermal Analysis was adopted to research IMPs ,in which ,a better thermal stability and its decompose temperature were showed in the results.

其次，本文利用紫外分光光度法研究磺胺二甲嘧啶和磺胺异噁唑与甲基丙烯酸或4-乙烯基吡啶的结合作用，结果表明，溶液中的功能单体与模板分子之间产生了结合作用，并预测磺胺二甲嘧啶和磺胺异噁唑印迹机理；分别分析了功能单体甲基丙烯酸、4-乙烯基吡啶、磺胺二甲嘧啶和磺胺异噁唑分子印迹聚合物的红外谱图，经过对比发现制得的印迹聚合物中C=C双键峰很小，并且功能键羧酸键和吡啶氮没有明显变化，这为聚合物特异识别特性创造了条件；利用综合热分析仪，对分子印迹聚合物进行综合热分析，结果表明分子印迹聚合物具有较好的热稳定性，分解温度也较高。

All indexes in cluytyl alcohol preparation group were better than pyroracemic acid and creatine group. Conclusions: Cluytyl alcohol preparation could enhance blood glucose contents, inhibit protein decomposition, advance sere testosterone levels and prevent myocardial damage. Therefore, Cluytyl alcohol preparation is a ideal drug of eliminating movement fatigue.

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。
