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.

On the basis of Ritter real morphological associative memory, complex lattices and complex rings are defined respectively through introducing two ordinal relationships between complex numbers, consequently the same recall rules are obtained as RMAM in complex domain and construct a class of complex MAM, called extended RMAM. The CMAM can directly process complex signals such as FFT-ed complex data.
在Ritter的实域形态联想记忆(real morphological associative memory,简称RMAM)模型的基础上,通过在复数域中序关系的引入构成复数格和环,导出了在复数域上与RMAM相一致的联想规则,构建了一类复域MAM(complex MAM,简称CMAM),从而将RMAM从实域推广至复域,使其可直接处理复信号如经FFT(fast Fourier Transformation变换所得数据。

A simple estimation method for molar Gibbs free energy and enthalpy of formation for complex oxysalt minerals is proposed. Complex oxysalt minerals are divided into complex oxysalt minerals with water and complex oxysalt minerals without water. Complex oxysalt minerals without water can be considered as the composite of acidic oxides and alkaline oxides, so their molar Gibbs free energy or molar enthalpy of formation can be calculated by the summation of molar Gibbs free energy or molar enthalpy of formation of the acidic oxides and alkaline oxides which are combined into the complex compounds.
