The advantage of supercritical carbon dioxide used as an environmental medium in polymerization and reactions in supercritical carbon dioxide are described. It includes homogeneous free radical polymerizations, precipitation free radical polymerizations, dispersion free radical polymerizations, emulsion and inverse emulsion free radical polymerizations, cationic polymerizations, ring-opening polymerization, melt-phase condensation polymerizations, sol-gel polymerizations, polymer blend synthesis, catalytic chain transfer polymerizations, oxidative coupling polymerization, nitroxide-mediated radical dispersion, atom-transfer radical polymerization, reversible addition-fragmentation chain transfer polymerization, electrochemical polymerization, simultaneous one-pot combination of enzymatic and chemical polymerization, copolymerization of carbon dioxide used as monomer.

To get more insight into the mechanism and kinetics of the RAFT process,it would be helpful to build a small molecular model reaction mimicking the RAFT process but free of a chain-propagation event. We hereby propose a model cross reaction between dithioester and alkoxyamine as a probe of the RAFT process,in which the alkoxyamine plays the role of the radical source.The generating rate of the transient alkyl radical and the nitroxyl radical can be described by the law of persistent radical effect.Thus,the advantage of the model cross reaction is that it affords a radical concentration determined by the known equation of the persistent radical effect.

为了更深入的理解RAFT聚合过程，我们构建了一个模型反应：即由烷氧基胺与双硫酯进行交换反应，烷氧基胺均裂产生的烷基自由基将会向双硫酯进行链转移，双硫酯的引入对纯烷氧基胺分解动力学造成的影响可以提供RAFT过程的许多信息。

This article starts with a review of the history of the "Expression" conception in the Occident literature tradition,from which to conclude the base connotation of modern "Expression" conception in occident.Relying on this springboard,we analyses the history of the occidental modern plastic arts gradually ,then the naissance and development of the occidental modern plastic arts may boil down to a going-deep course driven by the "Expression" conception:the impressionism which had been pursuing sensual reality brought out a turning point from Representation to expression;Faurism accomplished the consciousness of Expression based on inheriting and criticizing Post-Impressionisme, and resisted the suppressant on Expression by Physical Image; the German Expressionism and Surrealism uplifted Expression at the same time they resisted Physical Image by "Nugatory Physical image"; From the apocalypse of Cubism,Suprematism and De Stijl tended towards Pure Plastic which excluded Physical Image completely,meaning that it had realized absolute Expression in the range of plastic;After WW II,artsists in western detected that Pure Plastic had actually suppressed Expression newly,as a result of Abstract-Expressionism and Mirnirnaliam Art,Expression broke away from Pure Plastic gradually to seek some new possibilities other than plastic.

本文从对西方文艺传统中的"表现"观念的历史考察着手，归纳出西方现代"表现"观念的核心内涵，以此为基点来逐步分析西方现代造型艺术史，进而将西方现代造型艺术的产生与发展归结为在"表现"观念驱动下不断递进的历史进程：印象主义对感觉真实的追求为造型艺术由再现走向表现打开了缺口；野兽派在继承和批判后印象主义的基础上首次实现了表现的自觉，并在艺术中反抗物象对表现的压迫；德国表现主义与超现实主义以不彻底的"否定性物象"来张扬表现反抗物象；至上主义、风格派等则在立体主义的启示下走向完全排斥物象的纯粹造型，在造型的范围内实现彻底的表现；二战后的西方艺术家们察觉到纯粹造型已经掉转头来形成新的对表现的压制；经由抽象表现主义、最低限艺术，表现逐步摆脱了纯粹造型，寻求造型之外的新的表现可能。
