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.

The commercial application of SPC-01 catalyst for decomposition of tert-amylmethyl etherto produce isoamylene was reviewed.

介绍了SPC-01型催化剂在甲基叔戊基醚裂解生产异戊烯中的工业应用。

In this work, trially1 isocyanurate and trimethylolpropane trimethaerylate were used as a polyfunetional monomer of PP/PE blends, and the effects of radiation dosage, the kind and amount of polyfunetional monomer on the morphology and mechanical properties were studied.

本研究中采用三烯丙基异腈脲酸酯和三羟甲基丙烷三甲基丙烯酸酯为PP/PE共混体系的多官能团单体。研究了辐照剂量，多官能团单体种类和多官能团单体用量对共混物形态结构及力学性能的影响。

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.

交际能力和语法的关系应该是目标与途径的关系。
