Design and Implementation of Integrated Management Information System for a Community

社区是政府最基层的办事机构，工作繁多，涉及面广。社区管理在当前的工作过程中，仍存在一些待解决的问题，主要有以下几点：第一，底数不清，信息孤岛。第二，多头管理，工作不清。第三，信息不全，不利决策。如果能有一套科学的管理系统帮助工作人员收集信息，及时更新消息并掌握辖区动态，为领导者的决策提供依据，那么这套系统就有研究价值和意义。 基于以上情况本论文就从以下研究目标与内容进行探索：建设社区综合服务应用平台，通过该平台的建设，实现以下三个具体目标：第一，统一工作平台，整合各项工作。第二，相关信息关联查询：该平台实现从一个信息入口可以获取与此相关的其他信息，不需要再到不同系统分别检索。第三，辖区状况一...The community is the government's most basic level of service institutions, the work of many, involving a wide range of. Community management in the work process, there are still some problems to be resolved, mainly in the following points: first, incomputable, information isolated island. Second, multiple management, work is not clear. Third, incomplete information, adverse decision. If you can h...学位：工程硕士院系专业：软件学院_工程硕士(软件工程)学号：X201323203

Charge Exchange Spin-Dipole Excitations of 90Zr and 208Pb and Neutron Matter Equation of State

Charge exchange spin-dipole (SD) excitations of $^{90}$Zr and $^{208}$Pb are studied by using a Skyrme Hartree-Fock(HF) + Random Phase approximation (RPA). The calculated spin-dipole strength distributions are compared with experimental data obtained by $^{90}$Zr (p,n) $^{90}$Nb and $^{90}$Zr (n,p) $^{90}$ Nb reactions. The model-independent SD sum rule values of various Skyrme interactions are studied in comparison with the experimental values in order to determine the neutron skin thickness of $^{90}$Zr. The pressure of the neutron matter equation of state (EOS) and the nuclear matter symmetry energy are discussed in terms of the neutron skin thickness and peak energies of SD strength distributions.Comment: 26pages, 10figure

Protoneutron stars in the Brueckner-Hartree-Fock approach and finite-temperature kaon condensation

We study the properties of hot neutrino-trapped beta-stable stellar matter using an equation of state of nuclear matter within the Brueckner-Hartree-Fock approach including three-body forces, combined with a standard chiral model for kaon condensation at finite temperature. The properties of (proto)neutron stars are then investigated within this framework.Comment: 10 pages, 5 figures, 2 tables, PRC in pres

Fabrication and investigation of bioactive coatings on Ti alloys by micro-arc oxidation

医用钛合金由于其良好的材料力学性能以及化学、生物性能而被广泛用于骨科、齿科以及整形外科，但钛合金属于生物惰性材料，直接植入体内不能被组织细胞识别，会发生免疫排斥反应导致植入效果不佳。通过表面处理技术对钛合金表面进行改性，构筑具有生物活性以及生物相容性和其他相关性能的优异膜层，对医用钛合金材料的长期安全植入以及促进组织细胞攀附、增殖、分化和生长具有重要意义。 本论文在前期调研的基础上开发了一种制备钛合金微弧氧化生物活性黑色涂层的工艺，实现了钛合金表面改性，其中重点研究微弧氧化过程中电解液参数以及电源参数对膜层表面形貌以及组成、相结构、孔径、色度值、耐腐蚀性能、亲水性能以及力学性能等综合性能的影...Titanium alloys have been extensively used as orthopedic, dental and plastic surgery materials due to their excellent mechanical properties and biochemistry properties.

The Study on the Efficiency of Chinese Transmission Mechanism of Monetary Policy

1984年中国人民银行正式行使中央银行的职能，我国有了现代意义上的货币政策调控体系。随着改革开放的不断深入和国民经济的持续发展，我国货币金融体系在逐步地完善，货币政策传导机制也在不断地变化和调整之中。1998年我国正式取消了对商业银行的贷款规模限制，货币政策由过去的直接调控转为间接调控，货币政策传导机制发生了很大的变化。在此背景下，利用理论分析和实证分析相结合的方法研究我国货币政策传导机制的有效性，探讨阻碍我国货币政策有效传导的因素，并提出一些合理建议是本文的出发点所在。本文首先从理论角度研究了货币政策传导机制，详细论述了货币政策传导的货币渠道和信贷渠道。随后对我国货币政策传导机制的发展做了回...Since 1984 when the People’s Bank of China began to work as the Chinese central bank, the modern monetary policy formally included in China, and then the central bank reformed every aspect of the transmission mechanism of monetary policy. The transmission mechanism of monetary policy has been developing with the deepening of the Reform and Open and developing finance system. The transmission mecha...学位：经济学硕士院系专业：经济学院国际贸易系_世界经济学号：20030905

The on-line Observation for the unmeasurable Inputs of the CFB Boiler

循环流化床(CFB)锅炉燃烧系统是一个具有非线性、大滞后、多耦合的复杂过程，其自动控制比一般锅炉更加复杂和困难；加上一些对燃烧系统有重要影响的输入变量，如给煤煤质等，不能在线实测，导致重要的优化指标——锅炉热效率的实时计算难以实现。优化指标无法实时测算，闭环实时优化就无法实现。要研发CFB锅炉的闭环自动调优系统，首先必须解决不可(难)测输入变量的在线观测问题。基于以上原因，本文以440t/h循环流化床锅炉工业装置为研究对象，建立了基于机理模型的循环流化床锅炉的不可测输入的在线观测系统；对包括给煤含碳量及给煤挥发分含量的CFB锅炉燃煤品质进行在线观测研究。首先，在佘文武所建的220t/h循环流化...CFB boiler combustion system is a complex process for its nonlinear, large time delay and multi-variable coupling characteristics, thereof the close loop control and online optimization of its combustion process are considered as an extremely challenging problem.

人民币汇率制度的改革

从汇率制度选择和汇率形成机制两个层面探讨了人民币汇率制度改革的方向。汇率制度选择方面,主张人民币盯住一揽子货币,提高汇率的弹性和灵活性,增加人民币汇率的波动幅度,并积极参加区域货币合作,加速人民币的区域化和国际化进程。汇率形成机制方面,认为应该提高人民币汇率形成的市场化程度,以形成“均衡”汇率,分散风险
