The suspension polymerisation reactions of methyl methacrylate and styrene in inorganic/ organic composite ternary system are studied.

采用无机/有机三元复合分散体系进行了甲基丙烯酸甲酯与苯乙烯悬浮聚合的研究，对影响共聚物珠粒形成的因素进行了考察，得到了合成甲基丙烯酸甲酯—苯乙烯共聚物的工艺条件。

The effect of molecular weight, ethylene group and mixing of polyketone on the photodegradability were investigated. The mechanism of the photodegradation of ESTCO, STCO, STCO-PS and ESTCO-PS were reviewed. In addition, the block polymerization of methyl methacrylate initiated by STCO under UV irradiations was also studied.

研究了乙基取代基、分子量及共混物对聚酮光降解性能的影响，探索了STCO、ESTCO及其分别与聚苯乙烯共混物STCO-PS、ESTCO-PS的光降解行为和光降解机理，初步探讨了聚酮ESTCO光降解所产生的大分子自由基引发的甲基丙烯酸甲酯的聚合。

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.
