The comparison between propylene pigments and charcoal pencil formed a dream-like sunshine scene that set a pure visual space for the narration of the story.

丙烯材料和炭笔的结合营造了一种阳光下的梦幻场景，间接的场景呈现放弃了对作品主题的直接评判，完全是以一种纯视觉化的效果为作品设定了一个属於自己的特异时间。

This thesis includes two parts. The first part is study on hydroformylation of alkenes in ionic liquid-H2O system.

本论文分两部分：咪唑离子液体—水体系中的烯烃氢甲酰化反应研究和新型咪唑类手性季铵盐的合成。

The progress in alkylation reaction of benzene with long chain alkenes was introduced from the two aspects of catalyst research and reaction technology.

从催化剂研究和反应技术两方面介绍了苯与长链烯烃烷基化反应技术的研究开发进展。

In this thesis, we reported ZrCl_4 and BiCl_3 catalyzed hydroamination of alkenes and the synthesis of two titanium imido compounds.

本文报道了用ZrCl_4和BiCl_3催化的烯烃的氢胺化反应的研究和两个含钛氮双键络合物的合成，全文共分为三大部分： 1。

This catalyst system was applied in the cyclopropanation of other alkenes, and the results indicated that the catalyst system excelled mono-catalyst.

将这个催化体系用于其他烯烃的环丙烷化，结果表明，协同催化效果优于单一催化体系。

The olefmation of benzyl zinc bromides with aromatic aldehydes, which has some theoretical means and good application expectation, has good stereoselectivity and regioselectivity.

The key steps were the stereospecific conversion of both allylie carbamates 10 and 13 into 11 by Li_2Cu_3(CH_2)_5 and the stereoselective hydroxylation of unsaturated side chain by OsO_4-NMO.

合成的关键步骤是用Li_2Cu_3(CH_3)_5立体专一地转化烯丙醇苯胺基甲酸酯10和13成为11和用OsO_4-NMO在化合物16的不饱和侧链上立体选择性羟基化。

The polymerization of conjugated dienes on a cationic exchange resin was investigated.

在一连续的固定床反应器中，采用强酸性阳离子交换树脂催化剂，研究了共轭二烯烃在醚化条件下的反应行为。

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.
