Gold Scorpionates Capture Ethylene ― Transition metal-ethylene complexes, known for nearly 200 years, were first made famous by Zeise's salt, K[PtCl3(C2H4)] H2O, a once-mysterious complex in which an ethylene molecule binds side-on to the platinum atom.

金蝎合物俘获乙烯――人们早在1827就制备了过渡金属烯烃复合物，最近因蔡斯盐，K[PtCl3(C2H4)] H2O，一种烯烃分子缠绕铂原子曾经很神奇的复合物，而首次名满天下。

Expert knowledge: deep sea fish oil to deep-sea salmon as raw material derived, is rich in OMEGA-3 (Omega -3) fatty acids, which is a kind of polyunsaturated fatty acids, including eicosapentaenoic acid, docosahexaenoic acid and linolenic acid, can effectively regulate blood lipids, promote health.

专家常识：深海鱼油以深海三文鱼为原料提炼而成，含丰富的OMEGA-3（奥米加-3）脂肪酸，它是一种多元不饱和脂肪酸，包括二十碳五烯酸、二十二碳六烯酸及亚麻酸，能有效调节血脂、促进健康。

The copolysiloxane PSII3A the raio of fed monomers (M1/M2)=1/9, M1 is 4-undecylen-

比较了异构反应速率和异构转换率，以聚硅氧烷共聚物PSII3A[侧基比(M1/M2)=1/9， M1是对十一烯酰基偶氮苯， M2是对十一烯酰氧对氧基苯酯]为最佳。

This paper reviews the recent progress in the studies on the aromaticity as well as the general syn the tic method of annulenes.

本文综述了近年来轮烯的合成及芳香性的研究进展，介绍了各种轮烯的一般合成方法。

Both Mg and Al has no bonding with perfect sheet due to negative binding energy at all symmetric positions, however, the introduction of a Stone-Wales defect increased the binding energy at all adsorption sites to negative values.

Mg和Al不能稳定吸附在完整的石墨烯片上，但是引入SW缺陷降低结合能，使其能够稳定吸附在石墨烯片上。

The photo-oxidation has been initiated by irradiation ofα-pinene/NOx mixture, and ozonolysis has been initiated by injection of ozone orα-pinene under dark condition.

光氧化实验在恒温(303K)、恒湿(40%RH)用黑光灯辐照α-蒎烯与NOx的混合物引发；臭氧氧化在黑光灯关闭的条件下通过注入臭氧或α-蒎烯引发，并以甲醇作为OH自由基清除剂。

To attaining longlived charge separated states, the new compounds 7 and 8 of C60-S-2-thioxo-1, 3-dithioles derivatives were synthesized by Diels-Alder cycloaddition reaction. The structures generated by AM1 were used as the initial configurations for the density functional optimization at the B3LYP/3-21G level for all carbon and sulfur clusters, and some geometry conformation indexes were obtained. We found that C60 has been half-packed by the curved 2-thioxo-1, 3-dithioles derivatives.

为了获得具有长寿命电荷分离态的[60]富勒烯－富硫衍生物有机功能分子，我们设计了用单键硫桥键联[60]富勒烯和硫酮衍生物的分子7和8，用半经验AM1方法得出最低能量的几何结构，在此基础上用密度泛函 B3LYP/3-21G方法，对其进行计算，得出电子相关的优化参数，预测其稳定性。

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。
