The kinetic behaviors of ethylene homo- olymerization and ethylene / l-hexene co-polymerization , catalyzed by the metallocene catalyst PS-DVB-MC in an 0.5 L stainless steel reactor , were studied. The effects of polymerization conditions on ethylene polymerization , such as concentration of catalyst , temperature of polymerization , pressure of ethylene , molar ratio of AI / Z r , etc ., were also investigated . Some leading results were as follows : the activity of the catalyst PS–DVB- MC for ethylene homo-polymerization was high ( 1.053 x 107 gPE / mol Zr·h ), but the molar ratio of AI / Zr was low ( 350:1 ); the catalytic ability for ethyleneα-olefin ( such as l hexene etc .) co-olymerization was great , and the corresponding activity come up to a maximum of 1.753 x 107 gPE / mol Zr·h while concenlration of l-hexene was 0.080 mol / L ; the molecular weight of polyethylene was about 180,000 , meanwhile the molecular weight distribution was narrow ( 2.19 ); the bulk density of polyethylene and ethylene / l-hexene co -polymer were 0.25 and 0.34 respectively .

采用0.5L高压不锈钢反应釜，对催化剂PS–DVB-MC催化乙烯均聚和乙烯/ l-己烯共聚合的动力学行为进行了研究，详细考察了催化剂浓度、反应温度、压力、Al/ Zr比、1-己烯浓度等因素对乙烯聚合反应的影响，得到如下主要结论：催化剂PS-DVB-MC具有催化乙烯均聚的高活性(1.053×107g PE / mo1 zr.hr)，低Al / Zr比( 350：1 )；具有良好的催化乙烯与α-烯烃(如1-己烯等)共聚的能力，在1-己烯浓度为0.080 mol / L时，催化活性达到最大(1.783×107 g PE / molZr.hr)；乙烯均聚产物的分子量在18万左右，分子量分布窄( 2.19 )。

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.

The idea of regional tourism co-operation in China has appeared since the early years of 1980s',and some outstanding achievements have been made at that time. However,reviewing the co-operations that were putting into action in China,we may find that many of the co-operations are still emphasizing the form,the study,the pronouncement,and many idea are still on the level of regional tourism administration, lacking ideographical and maneuverable and practical measures and policies.
