Comparison of the Development of the Three Regions in China——On the Basis of the Measurement and Analysis of Agglomeration Effects

城市群的发展和集聚效应（Agglomeration）的发挥已经成为各国越来越关注的焦点，在我国，长三角、珠三角和环渤海经济区这三大经济区域的发展也逐渐成为学者的研究重点，许多学者更是提出了大长三角和泛珠三角的发展口号。然而，在这三大经济区域进一步发展之时，亟需对其目前的发展状况有一个准确的了解，因此，文章通过测量三大经济区域的集聚效应，试图揭示三大区域的发展状况，并通过对测量结果的分析，提出相应的改进与解决措施。 关于集聚效应的测量，目前我国学者大都集中于对产业或城市集聚效应的研究，少有对区域集聚效应，特别是对三大区域集聚效应的测量分析，因此本文通过借鉴国外的研究成果，试图对我国区域集聚效应...The development of big cities and the mechanism of urban agglomeration effects have been drawing more and more attention from the world. Meanwhile, the development of the Yangtze River Delta, the Pearl River Delta and the Circum-Bohai-Sea Region has been also becoming the focus of the researchers in China. Recently some people even mentioned the development of the Big Yangtze River Delta and the B...学位：经济学硕士院系专业：经济学院金融系_金融学(含保险学)学号：1562006115102

Design and Implementation of University Educational Administration Management System

随着当今社会信息技术的不断发展与成熟，高校教务管理信息系统已成为各高校教务管理工作中不可或缺的部分。在办学过程中，随着教学规模的扩大，学生和教师人数的增多，如果采用传统的人工作业，势必会增加管理的难度，产生较高的办学成本。因此，学校有必要开发一套教务管理信息系统对各类教务信息进行统一的管理，使用教务管理信息系统能够为师生提供全面而详实的信息，对于学校提高教学水平，推进教育信息化建设具有十分重要的现实意义。 论文以当今国内外教务管理信息系统发展的背景和现状为基础，针对目前教务管理工作中存在的不足，从信息系统开发的角度，结合教务管理相关需求，分析了系统所需的功能模块，并通过系统设计、系统实现详细...As the continuous development on information technology in recent years, college educational administration management information system has become an essential part of the educational administration work.

城市化演进与经济增长关系研究评述

城市化演进与经济增长以及经济的持续增长之间究竟关系如何?本文通过分析当前理论界的最新争论说明:首先,城市化演进与经济增长呈现"动态"的相关关系。其次,城市化演进与经济增长关系的具体表现存在着各自的前提条件、量化的评判和有效的边界,因此,即便在经济发展初期,两者之间也可能呈现负相关关系。第三,技术和技能的集聚,为城市化与经济的持续增长之间建立起稳定的正相关性提供了可能。第四,以经济增长为目的的政府行为可能具有"过度城市化"的倾向

Education-running by a Line of Industry and the Development and Reform of Higher Education

部门办学是我国高等教育重要传统之一。它在培养目标、资金来源、学科发展、专业设置、区域分布、招生与就业等方面有其特色和优势。但是在本位利益驱动下也存在过分强调“专业对口”、行业垄断等弊端。部门办学改革与一定的社会经济发展及人才培养模式变迁密切相关 ,具有双重影响。我们应结合国情 ,扬长避短 ,继续推进部门办学体制改革。Education-running by a line of industry is an important tradition in higher education in China. This practice has its own features and advantages in terms of targets of training, sources of funding, development of scholarly disciplines, enrollment, employment, etc. There are, however, corresponding disadvantages such as obligatory compatibility of disciplines and monopoly by a specific line of industry. In view of those factors and the national conditions, relevant measures of reform need to be introduced

梯度过渡层对硬质合金沉积类金刚石膜的耐磨性影响

目的 分析不同类型的梯度过渡层对硬质合金沉积类金刚石涂层耐磨性能的影响,制备出能有效改善硬质合金减摩抗磨性能的类金刚石涂层。方法 采用真空阴极电弧离子镀和等离子体增强化学沉积技术,在硬质合金基底上制备了Ti/TiC/DLC、Ti/TiN/DLC、Ti/TiN/TiNC/DLC和Ti/TiN/TiNC/TiC/DLC四种类型的Ti多元梯度过渡类金刚石涂层。通过GNEHM-150型洛氏硬度计和电子显微镜、MFT-4000多功能材料表面性能试验仪、纳米硬度测试仪,分别评价不同类型多元梯度过渡层对硬质合金类金刚石涂层的膜基结合强度、摩擦磨损性能及纳米硬度。结果 Ti/TiC/DLC、Ti/TiN/DLC、Ti/TiN/TiNC/DLC和Ti/TiN/TiNC/TiC/DLC四种类型涂层的膜基结合强度等级分别为HF3-HF4、HF5-HF6、HF1-HF2、HF1,对两种膜基结合强度较好的涂层（Ti/TiN/TiNC/DLC、Ti/TiN/TiNC/TiC/DLC）进行摩擦磨损检测,其摩擦系数分别为0.2、0.1,且经过60 min对摩,Ti/TiN/TiNC/TiC/DLC涂层仍未出现明显剥落。结论 梯度过渡层的类型对薄膜的膜基结合强度、摩擦性能有较明显的影响,Ti/TiN/TiNC/TiC/DLC结构的涂层膜基结合强度最好,具有最低的摩擦系数,表现出了优异的减摩抗磨性能,可有效改善硬质合金表面的耐磨性能

Vibrational Spectroscopy Criteria to Determine α-Pyridyl Adsorbed on Transition Metal Surfaces

Corresponding author. Email: [email protected]; Tel: +86-592-2189023[中文摘要]基于簇模型采用密度泛函理论在B3LYP/6-311+G**/LANL2DZ(metal)基组水平上计算了吡啶及α-吡啶基吸附于Pt、Pd、Rh、Ni四种金属表面的红外和拉曼光谱.通过详细地分析和比较计算结果与文献报道的实验谱图,提出了以N端吸附的吡啶分子和α-吡啶基这两种表面物种各自存在的谱学判据.计算结果表明在以上四种金属表面,α-吡啶基的拉曼活性比吡啶的小,而特征谱峰的红外强度与吡啶相当.该结果表明红外光谱是检测金属表面α-吡啶基的有效手段,也解释了采用表面增强拉曼光谱和红外光谱研究吡啶吸附在金属表面得出不同结构的原因.[英文摘要]Density functional theory calculations at the B3LYP/6-311+G**/LANL2DZ(metal) level were used to predict the infrared (IR) and Raman spectra for pyridine and α-pyridyl upon interaction with platinum (Pt), palladium (Pd), rhodium (Rh), and nickel (Ni) clusters. After carefully comparing the simulated IR and Raman spectra with the corresponding experimental spectra from literature, the characteristic frequencies for the metal surface adsorbed pyridine and α-pyridyl were determined. Our results show that on these metal surfaces α-pyridyl has a far lower Raman activity compared with pyridine, but their characteristic frequencies have comparable IR intensities. This is the reason why different adsorption configurations are proposed for the IR and the surface-enhanced Raman spectra (SERS). Our results indicate that IR spectroscopy is an effective tool to detect α-pyridyl adsorbed on metal surface.国家自然科学基金(20973143,91027009);国家重点基础研究发展规划(973)(2007CB815303,2009CB930703); 厦门大学(2010121020);国家科学人才培养基金(J1030415)资助项

EFFECTS OF BENZO(a)PYRENE AND PYRENE ON HAEMOGLOBIN CONTENT IN MUGIL SO-IUY

Mugil so iuy was exposed to different concentrations of benzo(a)pyrene, pyrene and their mixture of equal quantity, and its haemoglobin contents were examined. The results showed an obvious time response and dose effect. Under the same concentrations of 0.1,1.0,5.0,10.0 and 50.0 μg/L, the mixture of the two pollutants showed the greatest toxicity to haemoglobin content, while pyrene the lowest. The joint action of benzo(a)pyrene and pyrene was synergism. Fig 1, Tab 1, Ref 5国家自然科学基金项目资助 (批准号 :498760 2 9
