The integrative ability, organizing ability, communicative ability of trainings was deficiency. Fourthly, the power of social physical educators in Guangxi universities was so weak that it couldn't satisfy the need of specialty development. For example, the number of special teacher and the practicing ability of teachers are deficiency. The teachers that master special theoretic well and have practicing experience are deficiency especially. Fifthly, social physical practice base have not been building in Guangxi universities. And the necessary equipments of gymnasium are deficiency at the same time. Sixthly, the whole sports technology levels of new social physical students are low and hard to fit for social needing. Seventhly, the professional ideology of students is not stable enough. For example, the special concept and cognition of students are dim. The attitude for learning is not right. The most of students want to or have trend to change their profession after graduating. Eighthly, the ability of students fostered by social physical education in various Guangxi universities has a gap with the ability that students should hold for adapting the need of Guangxi employer. The special technical levels of social physical students are weak. Ninthly, in investigation of social physical personnel being demanded by Guangxi area employers, we found that few social physical personnels were demanded by business unit, the state-operated factory and mining enterprise because of being influenced by economical environment. And the more social physical personnels were demanded by social physical directors, fitness centers and each kind of sports association and so on.

这主要表现为：不够科学的课程体系，在实践性教学环节中的重视程度不够，对学生的综合能力、组织管理能力、社会交际能力的培养较为欠缺；4、对社会体育专业的发展需求这一点而言，广西各高校该专业的师资力量还略显薄弱，难以满足社会的需求，主要体现在：缺乏足够的专业教师数量、教师实践能力欠强，尤其缺乏既有较高理论素养又有实践经验的教师；5、社会体育专业的实习基地在广西各高校中都尚未建立起来，同时一些必备的体育场馆的设施也较为缺乏；6、由于入学时广西社会体育专业的学生在运动技术、技能整体水平相对较低，因此在一些专业方向的需求上难以达到满足；7、在专业思想这一方面而言，广西各高校社会体育专业的学生显得不够稳定，主要表现为：淡薄的学生专业观念，模糊的专业认识，不够端正的学习态度，甚至有相当一部分学生准备毕业后改行或有改行倾向；8、广西各高校社会体育专业培养学生目前所具备的能力与当前广西用人单位所需求的社会体育专业人才应具备的能力尚有一定差距，主要体现在：目前社会体育专业学生的专业技术水平较低，组织能力和社会交际能力较为欠缺等。9、在广西地区用人单位对社会体育专业人才需求量的调查中发现：大多数的企事业单位和国营厂矿企业因受到经济大环境的影响，基本上都不设置专职的体育管理人员，对社会体育专门人才的需求量较少，需求量较大的还是社区体育指导员、体育健身中心、各种体育协会等。

The characters of powder are connected with the inside structure and synthesize-technics of materials. In this paper, we want to search a optimize technics of materials synthesizing, and prepare a kind of nanosize powder which shape like ball and have good dispersed character.

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.
