A novel complex [Cd2（phen）4（phth）2]·4H2O has been synthesized by the reaction of Hzphth（phthalic acid） and phen（1,10-phenanthroline） with Cd（Ⅱ） in ethanol-water solution. X-ray crystal structure analysis shows it crystallizes in triclinic, space group PI- with a = 10.619（3）, b = 12.560（4）, c = 12.651（4） A, a = 98.775（5）, β = 109.035（5）,γ = 113-576（5）°, C32H24CdN4O6, Mr= 672.95, V = 1381.7（7）A^3, Rint = 0.0358, Z = 2, Dc= 1.618 g/cm^3,μ = 0.845 mm^-1, -6 ≤h≤13, -15 ≤k ≤13, -15 ≤l≤14, F（000） = 680, S = 1.038, R = 0.0480 and wR = 0.0849 for 3992 observed reflections （1 〉 2σ（Ⅰ））. Phth bridges Cd（Ⅱ） to form a macrocyclic compound, and a 2D supramolecular motif is formed through hydrogen bonds and π-π interaction.

A novel complex [Pb（qina）2（DMSO）]·H2O was synthesized, of which qinais the quinaldic acid radical and DMSO the dimethyl sulfoxide. Elemental analysis, IR spectra, and X-ray single-crystal diffraction were carried out to determine the composition and crystal structure. This complex belongs to monoclinic system, space group P121/n1, with a = 7.1553（17）, b = 17.543（2）, c = 17.306（2） A, β = 91.671（4）°, C22H20N206PbS, Mr = 647.65, Z = 4, V= 2171.5（6） A3, Dc= 1.981 g/cm^3, μ= 7.908 mm^-1, F（000） = 1248, -9≤h≤6, -23≤k≤19, -22≤1≤22, R= 0.0221 and wR= 0.0488. Weak coordinate bond is formed between oxygen atom in DMSO and Pb（ Ⅱ ）. There are also weak interactions, such as π-π interaction, hydrogen bonds and so on, among the complex molecules.

Two new complexes [Pd（L-phe）2·2H2O] （1） and [Pd（4,4＇-dcbpy）（en）·H2O] （2）（L-phe = L-phenylalanine, 4,4＇-dcbpy = 2,2＇-bipyridyl-4,4＇-dicarboxylate, en = ethylenediamine） were synthesized and characterized. L-phenylalanine was in situ formed via the hydrolysis of N-（tert-butoxycarbonyl）-L-phenylalanine, and ethylenediamine came from the in situ reaction of piperazine （pip） under hydrothermal conditions. The single-crystal X-ray structure analyses reveal that the Pd（Ⅱ） ion constructs a square planer coordination geometry in complexes 1 and 2, respectively. Complex 1 extends into a 2D layered structure via H-bond interactions and complex 2 connects into a 3D network through hydrogen bonds and 7r-tr stacking interactions. The interactions of 1 and 2 with fish sperm DNA （FS-DNA） were examined via UV-Vis absorption spectra and fluorescence spectroscopy. The cleavage reaction for plasmid DNA has been assayed by agarose gel electrophoresis. The results indicate that two complexes interact with DNA and the insertion is the main binding mode.

Two three-dimensional lanthanide（Ⅲ） coordination polymers with the formula [Ln（PYDC）（NA）（H2O）]n [Ln=Gd（1）, Eu（2）, H2PYDC=pyridine-2,5-bicarboxylic acid, HNA=nicotinic acid] have been hydrothermally synthesized and characterized by elemental analysis, IR, and single crystal X-ray diffraction. The NA came from in situ decarboxylation of the part of PYDC. X-ray single crystal structural analyses reveal that complexes 1 and 2 are isomorphous, they possess the 43.63 topology assembled by Gd^3＋/Eu^3＋ and two different multidentate carboxylate ligands Magnetic measurements show that antiferromagnetic coupling exists between adjacent Gd^3＋ ions in complex 1. The complex 2 exhibits the corresponding characteristic luminescence in the visible region under an excitation at 305 nm.

通过构建两任务部门生产模型,并借助高校扩招的准自然实验,考察了人力资本扩张对中国居民性别工资差距的影响。结果发现:人力资本扩张将男性工资提高了6.2%,女性工资提高12%,最终导致性别工资差距缩小8.4%。进一步研究发现,人力资本扩张缩小了教育年限的性别差距,由于女性教育回报率高于男性,进而导致性别工资差距降低。从异质性角度来看,人力资本扩张对服务业部门、中低收入、低学历、东部地区群体的性别工资差距影响更大。

为分析PET(聚对苯二甲酸乙二醇酯)再生纺织品的环境效益及其生产过程中的重点改进因素,基于生命周期评价(LCA)研究思路,采用经济价值分配结合cut-off规则的方法对废弃PET材料作为原生材料时产生的环境负荷进行分配,核算出再生技术与原生技术(所生产的产品具有相同消费功能)两个模拟情景的环境负荷,并对再生工艺流程的LCA模型进行归一化分析与敏感性分析.结果表明:相对于原生技术,再生技术每生产1t PET再生纺织品可减少1640kg的温室气体排放,并节约40400MJ的不可再生能源使用,人体毒性潜值、富营养化潜值、淡水生态毒性潜值等环境影响指标均有不同程度的下降.6个生产工艺环节中反应增容对总体环境负荷的贡献最大,电力与甲基丙烯酸缩水甘油酯的消耗量应作为重点改进因素.
