Design and Implementation of the ITIL-based Integrated Management Platform for Operational Maintenance of Finance and Taxation

天津市某税务局的信息化建设从上世纪80年代起步，经历了30余年的发展。随着信息化整体建设的进步，该局的运维体系建设则逐渐地落后于系统建设的发展要求。目前该局的信息化运维尚处于传统运维阶段，即一种被动的运行维护管理模式，是救火式的运维。通常是用户先于信息化运维人员发现问题，然后再找到信息化部门要求解决问题。如何改变该局运维工作基于设备的、人工的管理模式，扭转救火式的被动运维的局面，转变以设备和技术为主要关注点的运维理念，成了摆在我们面前的一个首要问题。 本文针对上述问题，根据该局信息化建设实际情况，提出了基于ITIL思想建设财税运维综合管理平台的设想，并最终予以实现。ITIL是目前国际上比较通...The information construction of one IRD of Tianjin, started in the 1980s, has developed for more than 30 years. With the advancement of information construction, the development of operation and maintenance system is begining to fall behind the requirements of the system construction, generally. The current operation and maintenance of IT is still in the traditional phase, which is a passive opera...学位：工程硕士院系专业：软件学院_工程硕士(软件工程)学号：X201323243

评《郊区卫士——美国新右派的源起》

右翼势力一直是美国社会政坛一股不容小觑的力量,也是共和党的政治基础。在美国历史上,右翼力量经历了不断的分化组合,有新老之分。老右派主张地方自治,标榜“管得最少的政府就是最好的政府“,在二战后极力反对共产主义。与之相比,美国新右派(nEW AMErICAn rIgHT)的政治主张有所不同。右翼势力一直受到学

城市化进程中非农就业的现状与对策分析

非农就业是现代化和经济发展的必然趋势,也是城市化的必然选择,更是解决“三农“问题的治本之策。当前,由于城市化与工业化发展不平衡,为城市化而城市化的现象突出,致使非农就业水平长期低下。因此,要扩大非农就业,就必须确立以人为本的城市发展观,加快第三产业的发展,建立健全非农就业的支持系统

Theoretical calculation and simulation of shallow dopants in InGaN single junction solar cell

通过氢有效质量理论(HEMT)对In0.65gA0.35n(高In组分,Eg=1.31EV)太阳电池材料进行分析,计算出其浅能级施主和受主的重要性质参数电离能:ΔEd~10.8MEV,ΔEA~90MEV.在此基础上得到了室温条件下In0.65gA0.35n的浅能级施主和受主强电离时的杂质浓度范围:施主9.56x108~4.57x1016CM-3,受主9.56x108~7.84x1016CM-3;并估算了产生杂质能带的最低杂质浓度:施主~1x1018CM-3,受主~5.79x1020CM-3.然后借助AMPS-1d软件对含有部分电离的浅能级施主、受主In0.65gA0.35n单结太阳电池进行模拟,详细讨论了施主能级和受主能级对载流子的俘获对太阳电池效率的影响.本文结果为IngAn单结和多结太阳电池的掺杂(尤其是P型掺杂)和制备提供了理论参考和帮助。Hydrogenic effective-mass theory(HEMT) was adopted to study the photovoltaic property of In0.65Ga0.35N(Eg=1.31 eV).The ionization energy of shallow donors and acceptors in In0.65Ga0.35N was calculated to be ΔED ～10.8 meV and ΔEA～90 meV,respectively.Based on these values,the doping concentration necessary to obtain strong ionization of shallow dopants was estimated to be 9.56×108-4.57×1016 cm-3 for donors and 9.56×108-7.84×1016 cm-3 for acceptors.The lowest doping concentration required to form impurity bands was found to be ～1×1018 cm-3 for donors and ～5.79×1020 cm-3 for acceptors.Using AMPS-1D software,the property of single junction solar cell containing partially ionized shallow dopants,was simulated.The effects of recombination of shallow dopants on the efficiency of the solar cell were analyzed and discussed in detail.The results are useful for doping(especially for p-type doping) and fabrication of InGaN-based single junction and multijunction solar cells.国家高技术研究发展计划(2006AA03Z409);厦门市政府科学和技术部研究项目(2006AA03Z110);广西自然科学基金(0731012);广西大学有色金属和高等材料加工新技术教育部重点实验室开放基金(GXKFZ-04)资

Z-十八碳-9-烯-丙磺酰胺对糖尿病认知功能障碍小鼠学习记忆功能的影响

探索新化合物Z-十八碳-9-烯-丙磺酰胺（N15）对糖尿病认知功能障碍（DACD）小鼠学习记忆功能的作用及机制。采用链脲佐菌素（STZ）连续小剂量腹腔注射以及高脂高糖加STZ诱导2型糖尿病小鼠模型,N15(50和100mg·kg-1·d-1)连续灌胃给药6周,于给药末期进行跳台、避暗以及Morris水迷宫测试以评价小鼠学习记忆功能;对海马内葡萄糖和乳酸水平进行测定;通过realtimePCR测定海马内突触成长相关蛋白-43（GAP-43）、突触素（SYN）、脑源性生长因子（BDNF）和神经营养因子-3（NT-3）m RNA的表达。结果表明,N15可显著改善模型小鼠学习记忆能力,降低海马内葡萄糖和乳酸含量,显著上调海马内GAP-43、SYN、BDNF和NT-3 m RNA表达水平。上述结果表明,新型化合物N15具有改善糖尿病认知功能障碍的作用,其机制可能与增加海马内突触生长相关因子和神经营养因子表达相关。福建省教育厅资助项目(JAT160583

星系中心大质量黑洞及潮汐瓦解恒星事件

黑洞潮汐瓦解恒星事件(Tidal Disruption Events,TDE)是星系中心黑洞瓦解进入其潮汐瓦解半径内的恒星并吸积恒星碎片物质而产生的一种剧烈辐射耀发现象.TDE的能谱和光变特征中蕴含了中心黑洞和被瓦解的恒星的信息,为我们证实和普查宁静星系中的黑洞,研究其参数、吸积过程和喷流产生、以及核区星际介质等提供了可能.TDE还可能提供中等质量黑洞和双黑洞存在的证据.TDE的观测和理论已成为一个新开辟的天体物理研究领域,但目前的进展受制于探测到事件太少(尤其是在X射线波段),且观测数据普遍质量不高.TDE的发生率很低,要探测大样本的事例需要监测足够大的空间体积.爱因斯坦探针卫星(Einstein Probe,EP)覆盖了0.5–4 keV的软X射线波段(接近TDE耀发时的辐射峰值能段),具有大视场以及高灵敏度,非常利于对TDE的探测.预期爱因斯坦探针卫星每年可以发现约几十至上百例TDE,其中有约10例或更多具有相对论性喷流特征.这将使我们可以获得较为完备、具有统计意义的TDE的样本,为进一步研究黑洞的存在和统计性质、增长和演化、发现中等质量黑洞和大质量双黑洞等提供了新的途径.中国科学院空间科学战略性先导科技专项(编号:XDA15052100);;北京大学“985工程”建设项目“星团环境对双黑洞形成演化过程的干扰及其对引力波探测的影响”资
