The Sn atoms are considered as five-coordinate and exist as distorted trigonal bipyramidal geometry in a one-dimensional chain.

合成化合物的中心Sn原子为五配位，构成以Sn为中心，扭曲的三角双锥构型，通过分子间氢键形成一维链状结构。

The interaction of two NO molecules and NO dimers with Cu2 has been studied at B3LYP/Lanl2DZ level.

采用密度泛函理论中的B3LYP方法，在Lan12DZ基组下，对NO双分子和二聚体与铜原子簇相互作用的结构进行了研究。

The increase in torsion angle between two phenyl rings as external bias increasing results in a weaker intramolecule coupling, which leads to a smaller conductance.

同时这种双硫原子的连接方式在外电场存在的情况下，其扭转角会随着偏压的改变而发生突变，从而使分子呈现出独特的电致开关的作用。

Organic molecules in the double bond or triple bond was broken, added of other atoms or groups of reaction is called addition reaction ...

The results showed that C 2H 6 can be adsorbed on the surface terminal oxygen of Lewis base site P=O bonds through H atom in -CH 3 to form a molecular adsorption state, and the adsorption intensity of C 2H 6 increases with the rising of adsorption temperature.

结果表明，乙烷能够以 CH3 中的H原子吸附于催化剂表面P =O键的端氧上形成分子吸附态，并且随着吸附温度的升高，对乙烷的吸附强度逐渐增大；乙烯则主要是以C =C双键吸附在催化剂的Lewis酸位Fe3 +上。

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。
