Synthesis, Characterization and Studies on Thermokinetics of the diastereomeric Transfer of Chiral Pentacoordinate Spirobicyclic Aminoacylphosphoranes（P-AAs）

五配位磷是生命过程中的反应过渡态和中间体，N-磷酰化氨基酸自组装成肽也经过五配位磷的中间体，研究含有氨基酸的五配位磷意义重大，研究五配位磷化合物立体化学互变异构的热动力学性质有助于进一步揭示生命体内酶的手性催化机理。我们设计合成系列氨基酸五配位双螺环磷烷作为研究生命体内五配位磷化合物的模型。 本论文采用新的一锅法合成系列氨基酸双螺环五配位磷烷（P-AAs）。由于P-AAs非对映异构体容易发生互变，因此分离十分麻烦。本论文首次结合正相硅胶柱层析法与多次重结晶法成功分离获得9种氨基酸双螺环五配位磷非对映异构体。P-AAs原子数目很多（特别是芳香碳），本论文通过核磁...Pentacoordinate phosphorus compounds have been recognized as the intermediates or transition states in biological system.They are also intermediates in self-assembly reactions of N-phosphoamino acids into peptides. It is important to study on pentacoordinate phosphorus containing -amino acid moiety since it is the model for study the mechanism of enzymatic chiral reactions. In this thesis,...学位：理学硕士院系专业：化学化工学院化学系_有机化学学号：2052008115167

International Coordination of E-Business and China’s strategies in the Post-crisis Era

电子商务快速发展带来许多全球化问题,这些问题不能在一国内得到解决,需要各国的协调一致行动。现有的官方和非官方组织在电子商务的多个领域展开协调,有效防止数字鸿沟的继续扩大,为电子商务创造了良好的发展环境,保证了交易数据安全,在消费者保护方面也取得积极效果。中国电子商务起步较晚,应采取积极措施顺应电子商务的全球发展趋势,为后危机时代中国电子商务的发展创造良好的制度环境。E-business is playing a key role in individual country’s economy as well as in global economy.Its global nature brings some problems to it,which can not be solved interiorly.The official and non -official organizations have undertaken due obligations to e-business coordination in many aspects,and gained remarkable achievements.How China’s e-business will develop is an important issue.The paper analyzes the strategies that China can take in order to survive during the post-crisis era

Synthesis and Glucose-Responsive Properties of Phenylboronic Acid based Polymerized Crystalline Colloidal Array

葡萄糖是体内碳循环和能量的主要运输形式。若人体内正常血糖平衡遭到破坏将引起纤维囊肿、肾性糖尿、糖尿病等疾病，从而严重影响人类身体健康。准确测定人体血糖浓度是控制和治疗糖尿病等糖代谢相关疾病的重要基础。 目前常用的针刺指尖采血检测法给患者带来一定的痛苦和不便，这使得无创检测葡萄糖以获取血糖浓度的途径显得尤为重要。其中，较有实际意义的无创伤技术是通过检测人体组织液（例如：泪液、尿液）中的葡萄糖浓度，并且利用组织液葡萄糖含量与血糖浓度之间的关系，以间接得到血糖浓度。 本文选用苯硼酸基团（phenylboronicacid）作为识别基元，制备了葡萄糖响应性聚合胶体光子晶体，主要工作如下： 1、新...Glucose is the main transport form of the Carbon-cycle and energy in the body. Certain diseases such as cystic fibrosis, renal glycosuria, and diabetes have been aroused because that the balance of blood sugar is breakdown, which has been seriously affected human life. Therefore, the accurate monitoring of glucose concentrations is important foundation in the management and treatment of the diseas...学位：理学硕士院系专业：化学化工学院_高分子化学与物理学号：2052011115156

A Study on Management Mechanism of Government Loan: the International Guidelines and Its Inspiration to China

中国政府对外优惠贷款产生于1995年，是中国对外援助的最要组成部分，有效促进了受援国的发展，引起国际社会的广泛关注。随着优惠贷款规模的扩大，现有的管理机制已不能满足其发展需要。政府贷款是西方国家提供发展援助的重要手段，已有半个多世纪的历史，并形成了较为完善的管理机制。中国可借鉴西方经验教训，改革中国政府对外优惠贷款管理机制。 本文通过案例研究和比较研究的方法，研究了对外援助管理体系的总体框架，并在此基础上研究了日本、法国和中国三个案例国家的政府贷款管理机制，并对三国政府贷款管理机制进行对比，之后给出本文的政策建议。 案例分析的章节安排上，政府贷款管理机制是对外援助管理体系的有机组成部分，其...Chinese Government Concessional Loan appeared in 1995. As China’s most important modality of foreign aid, Concessional Loan improves the economic and social situations of partner countries and that of China effectively. But the management mechanism of Concessional Loan can not acclimatize itself to its rapid development and needs urgent reform. Over the past half-century, Government Loan has bee...学位：经济学博士院系专业：经济学院国际贸易系_世界经济学号：1572008015024
