查询词典 isobutylene

Molecular dynamics simulations of NPT (constant pressure and constant temperature) dynamics are carried out to obtain specific volume as a function of temperature for polyethylene , polypropylene , poly-isobutylene , polyoxymethylene , and polydimethylsiloxane .

用NPT分子动力学模拟来获得聚乙烯、聚丙烯、聚异丁烯、聚甲醛和聚二甲基硅氧烷在不同温度下的特征体积。体积玻璃化转变温度通过对模拟得到的V-T作图的曲线的拐点决定。

This item plans to construct 5 thousand t/y Tert - butylamine production equipment which uses internally developed independently isobutene cyanide process for the production of raw materials for pure isobutylene, purity of 99.5% of the domestic production of tert - butylamine.

该装置采用国内自主开发的异丁烯氰化法生产工艺，以纯异丁烯为原料，生产纯度为99.5％的叔丁胺产品。

A four-ball tester was used to evaluate the load carrying and antiwear properties of bismuth dibutyldithiocarbamate,bis-dibutyldithiocarbamates(V7723),sulfurized isobutylene,molybdenum ester non sulfur and phosphorus in a mineral oil respectively and their synergistic effects.

利用四球试验机评价了二丁基二硫代氨基甲酸铋与二丁基二硫代氨基甲酸酯(V7723)、硫化异丁烯和非硫磷钼酸酯添加剂的极压和抗磨性能，以及它们之间的极压和抗磨协同作用。

A four ball tester was used to evaluate the antiwear and extreme pressure properties of antimony dialkyldithiophosphate with friction reducer containing phosphorus, chlorinated paraffin(T301) and sulfurized isobutylene (T321), and their synergistic effects.

利用四球试验机评价了二烷基二硫代磷酸锑与含磷摩擦改进剂、氯化石蜡(T301)、硫化异丁烯(T321)3种添加剂的极压和抗磨性能，以及它们之间的极压和抗磨协同作用；利用市售演示仪评价了SbD-DP、T301和T321之间的协同抗擦伤能力。

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。
