It is a highly flexible rubber liner based on EPDM (Ethylene-Propylene-Diene terpolymer), a polymer used for the production of vulcanised elastomeric geomembranes.

乙烯-丙烯-二烯三元共聚物的高弹性橡胶膜，这种聚合体曾用于生产硫化弹性橡胶膜。

Most components of essential oils are terpenes that contain multiples of a five carbon structural unit, the isoprene unit Fig.

精油中大部份的成份是由多个五个碳结构单元，即异戊二烯单元组成的萜烯类图1

In addition to reducing the directly emitted ozone and its associated impacts, the regulation will reduce the likelihood of particle and formaldehyde formation when limonene or other terpenes are present indoors.

除了减少臭氧的直接排放和与之相关的影响外，这一条例还将减少室内存在柠檬烯和其它萜烯时颗粒物和甲醛形成的机会。

The reductive hydrogenation of sterols is stronger downward with the depth,and that is much stronger in Site 8 than in Site 17 due to the different sedimentary circumstances.

随着沉积深度的增加，甾烯醇的加氢还原作用越强，且由于两个站位不同的沉积环境，8站位甾烯醇的加氢还原作用更强。

RESULTS: Expression of iNOS proteins was seen on day 1 following the control stent implanting, developed on day 3, peaked on day 10 and lasted till day 28. iNOS expressions at all time points in diallyl trisulfide coated stent group were higher than those in control stent group. Compared with normal blood vessel tissue, the NO production after stenting decreased on day 1, increased on day 3, maximized on day 10, went down to its pre????stenting level on day 28. At all time points, NO levels in allitridi????stented sites were higher than those in control????

结果： 对照支架组术后1 d血管壁中有少量iNOS蛋白表达，3 d表达增加，10 d达高峰，28 d时仍有表达，二烯丙基三硫化物涂层支架组iNOS蛋白在各时间点的表达量均高于对照支架组；对照支架组术后1 d时NO生成量低于正常组织，3 d时NO水平升高，10 d时最高，28 d时降至基线水平，二烯丙基三硫化物涂层支架组各时间点的NO水平明显高于对照支架组。

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。
