In this thesis, a series of complexes based on aromatic multicarboxylic acids have been successfully synthesized in solutions or under hydrothermal conditions. Their structure and properties are investigated.(1) Eight complex compounds have been synthesized and characterized by X-ray single crystal diffractive technology: The eight complexes are listed as following: [Cu242] complex 1 [Cd22(H2O)4]·4H2O complex 2 [Co(H2btc)(H2O)3] complex 3 [Co2(H2O)2]·H2O complex 4 [Ni22(H2O)4] complex 5 [Cu22(H2O)4] complex 6 [Co(H2biim)2(H2O)2](H2btc) complex 7 [Zn(H2biim)2(H2O)2](H2btc) complex 8 The structure of complex 1 is dinuclear complex resulted from weak interactions（0-D chain）; complex 2 is 1-D chain stucture result from interactions of water molecules; complex 3、4、5、6 are coordination polymers using hydrothermal synthses, where the first kind ligand is H4btc, the second kind ligand is phen and Co2+、Ni2+、Cu2+ as center ions, respectively. While the coordination enviroment of Co2+ is the same in complex 3, the coordination geometries around the Co atoms in complex 4 are obviously different because of the different reaction conditions. In complex 4, the 1-D chains are connected into 2-D layer through carboxy groups of ligand H4btc. The structures of complex 5、6 are 1-D chain stucture result from interactions of carboxy groups in ligand H4btc. Complex 7、8 are homeomorphy compounds. Either of them are linked to the 3-D chains through intermolecular hydrogen bonds. Each H4btc lose two protons and H2btc2- acts as negative electron balance.

合成了8个结构新颖的配合物，并用X-射线单晶结构分析方法确定了晶体结构，分别为： [Cu242] 配合物1 [Cd22(H2O)4]·4H2O 配合物2 [Co(H2btc)(H2O)3] 配合物3 [Co2(H2O)2]·H2O 配合物4 [Ni22(H2O)4] 配合物5 [Cu22(H2O)4] 配合物6 [Co(H2biim)2(H2O)2](H2btc)配合物7 [Zn(H2biim)2(H2O)2](H2btc)配合物8 配合物1是一个依靠弱作用连接的双核铜结构；配合物2借助水分子形成一维链状结构；配合物3、4、5、6是以H4btc为第一配体、phen为第二配体，通过水热法合成的配合物，其中，Co2+、Ni2+、Cu2+为中心离子；配合物3中的二价钴离子具有相同的配位环境，不同反应条件下得到的配合物4中的二价钴离子存在不同的配位环境，在配合物4中，一维链通过H4btc上的羧基形成一个二维层结构；配合物5、6是借助H4btc上的羧基形成的一维链状结构；配合物7、8属于异质同晶结构，它们的分子通过分子间氢键形成三维网状结构，H4btc上的羧基失去2个质子，作为一个二价负离子起到电荷平衡作用。

This paper is to make an analysis of Russian verbs from the perspective of valent capacity of verbs.

本文将借鉴配价语法中有关动词配价的理论，从动词配价能力的角度对俄语动词进行分析。

The third one indicates that instrument isn't the essential factor of verbal relation, so it has no qualification to play the part of valent component.

在此基础上再进入语用平面，描写和分析动词配价成分在实际话语中的一系列语用变化，一是配价成分的隐现，二是配价成分的移位。

In this part, the central place of verbs in sentences is expounded; the history and development of the study of valent grammar is discussed; the purpose and task of this paper is proposed.

配价语法和传统语法的根本不同之处在于：谓语动词中心论是配价语法的出发点，主谓核心说是传统句法分析的出发点。2）配价的本质。

In each category, semantic and syntactic valent models of verbs are generalized.

根据三价动词的词汇—语义特点把动词划分成五个语义小类并概括出每小类动词的语义价模式以及句法价模式。

While high quality deposition from trivalent chromium electrolyte could only be sustained for short periods and thin deposits obtained of decorative value only, it is difficult to substitute heaxvalent chromium plating in engineering electrodeposits by trivalent chromium plating at all.

因此，本文在电沉积出镍-铁合金纳米晶的基础上，采用脉冲电沉积的方法研究了在三价铬体系中获得纳米晶铬和铬-镍-铁合金纳米晶厚镀层的工艺及其基础理论，以期解决三价铬镀液完全代替六价铬电镀的难题。

But this leads immediately to overbidding, because risk-neutral equilibrium bidding entails a great deal of shading: A buyer will bid only one-half her valuation.

不过其直接的结果就是喊价过高，因为风险-中性的竞标者在均衡时的喊价要求作相当程度的削减：竞标者的喊价只能是其评价的一半。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
