The all cis-structure of the cyclizative product was found. The construction of the enolic hydroxyl structure became easier and excellent.

合成中发现环化产物为全顺式结构，烯醇式结构的建立更为简洁、高效，异丙基在较复杂的结构下实现了一步引入。

The leftover from bamboo processing was comminuted into bamboo fine powder, which was surface-treaded with a coupling agent of ethenyl tri (β-methoxyethoxy) silane; and then in the presence of initiator dicumyl peroxide, the powder was compounded with styrene-isoprene block copolymer/bromobutyl rubber blend to prepare a crosslinked vibration-absorbing rubber composite material.

将竹加工的边角料粉碎并用乙烯基三硅烷偶联剂处理，再与苯乙烯－异戊二烯嵌段共聚物和溴化丁基橡胶的共混物进行复合，在过氧化二异丙苯引发剂的作用下制得交联型橡胶吸振复合材料。

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.
