In this research, two novel compounds in which alkylenedithiomethylene Malonic acid act as the main coordination agents and the compounds containing N atom (such as pyridine, Phenanthroline Ethanediamine and 4,4'-Bipyridinyl) act as the associating coordination agents have been synthesized by the means of solution and solid-liquid diffusing reactions. 9 coordination complexes and polymers have been designed and synthesized in which the transition metals Cu and Zn acted as the centre ions. These compounds have been characterized by X-ray single crystal diffraction analysis, and some properties of them have been tested and analyzed.

本论文设计合成了两种结构新颖的含有二硫缩烯酮结构的丙二酸类化合物，以此为主要配体，以含氮化合物(吡啶、邻菲罗啉、乙二胺和4，4'-联吡啶)为辅助配体，采用常规溶液合成和固-液相扩散等方法，设计合成了9个过渡金属Cu和Zn离子配合物和配位聚合物，采用单晶X-射线衍射等技术对晶体结构表征，并对其部分性质进行了测试和分析。

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。
