Application of Subordinated Debt in Capital Management of State-owned Commercial Bank

论文摘要资本监管是商业银行审慎监管的核心内容，实施严格的资本监管制度，有利于提高银行体系的稳健性，促进金融市场的公平竞争，保护存款人利益；从商业银行自身角度看，有效的资本管理不但有利于银行自身的风险控制和业务发展，而且也有利于股东价值最大化的目标的实现。内外部环境的变化都要求国有商业银行尽快提高资本充足水平，提高抗风险能力，但目前国有银行缺乏有效的补充资本渠道。本文对国有商业银行通过发行次级债实现对银行资本管理进行了探讨。文章总共分四个部分：第一章简要介绍什么是次级债及其在国际上的相关实践，并回顾了我国在这方面的法规沿革，介绍相关法规的主要内容；第二章结合中国银行和中国建设银行次级债的发行情况...AbstractAs adequate capital is vital in order to keep the stability of bank system, promote the fair play of financial market and protect the interest of depositors, capital regulation is the core of bank supervision. And effective capital management can help commercial banks to achieve the goals of controlling risk and maximizing value of their shareholders. With the change of inside and outside ...学位：工商管理硕士院系专业：管理学院工商管理教育中心_工商管理硕士(MBA)学号：20011512

Progress in Laser Ignition Based on Passively Q-Switched Solid-State Lasers

稀薄燃烧是一种先进的燃烧方法,采用稀薄燃烧技术可以使发动机在减少废气排放的同时提高热效率。稀薄燃烧催发了激光点火技术的应用。最近几十年,脉冲宽度短、峰值功率高的被动调Q固体激光器得到了飞速的发展,特别是采用掺钕离子(nd3+)和镱离子(yb3+)的激光材料作为激光增益介质,用Cr4+∶yAg作为被动调Q开关的微片固体激光器在激光点火研究方面取得了长足的进展。系统地介绍了激光点火的机理和应用于激光点火的基于nd∶yAg/Cr4+∶yAg与yb∶yAg/Cr4+∶yAg的被动调Q固体激光器的最新研究进展,以及两类被动调Q激光器在激光点火应用中的优缺点,并指出了yb∶yAg/Cr4+∶yAg被动调Q微片激光器在激光点火应用中的优势、需解决的问题及发展方向。Laser ignition technology emerges as an advanced combustion method for engine.It can make the engine reduce waste gas emission and improve the thermal effect.Lean burning improves thermal efficiency and reduces exhaust emissions by laser ignition.In recent decades, short pulse, high peak power passively Q-switched solid-state lasers are developed rapidly for their potential applications in laser ignition.Especially the passively Q-switched lasers using neodymium ion(Nd3+) or ytterbium ion(Yb3+) doped materials as the laser gain media and Cr4+∶YAG as the saturable absorber, make much progress in potential laser ignition applications.We overviewe the mechanism of laser ignition and progresses in passively Q-switched solid-state lasers based on Nd∶YAG/Cr4+∶YAG and Yb∶YAG/Cr4+∶YAG.And the advantages and disadvantages of these two types passively Q-switched lasers used in laser ignition are discussed systematically.The advantages of Yb∶YAG/Cr4+∶YAG passively Q-switched microchip lasers used in laser ignition are addressed for future application in engine ignition.And the key issues for developing high peak power Yb∶YAG/Cr4+∶YAG passively Q-switched microchip lasers are also addressed.国家自然科学基金(61275143); 教育部新世纪优秀人才支持计划(NCET-09-0669

THE EFFECT of HIGH AMMONIA CONCENTRATION ON GILL STRUCTURE ALTERNATION AND EXPRESSION of SOD AND HSP90 GENES IN GRASS CARP,CTENOPHARYNGODON IDELLA

实验通过测定草鱼的24H半致死浓度,鳃的细胞结构以及SOd和HSP90的表达模式研究了草鱼在组织学和分子生物学水平上对高浓度氨氮暴露的响应。经过半致死实验确定的氨氮24H lC50为243 Mg/l试验中草鱼被置于5个浓度的处理组中(50、72、104、151、220 Mg/l),之后取鳃组织进行组织切片分析,取肝脏、肠和鳃来测定SOd和HSP90的表达情况。经过高浓度的氨氮暴露处理,鳃组织的细胞排列和结构产生了明显的变化,并且SOd和HSP90的表达受到了显著的上调。这些结果表明,高浓度的氨氮能够损害鳃部的细胞结构并且诱导应激蛋白的表达。这个结果同样显示出,SOd和HSP90可以作为评估草鱼氨氮暴露水平的良好指标。Histological and molecular responses of grass carp Ctenopharyngodon idella to high concentration ammonia exposure were studied in this study by determining the lethal concentration,gill cellular structure,and expression patterns of sod and hsp90 genes.Grass carps were treated at five ammonia concentrations(50,72,104,151 and 220 mg/L) for 24h,and then the gill tissues were collected for histological analysis.In addition,three tissues(gill,intestine and liver) were collected to measure the expression of sod and hsp90 genes.After exposure to high concentration of ammonia,the arrangement and structures of gill cells changed dramatically.Edema and fusion of secondary lamellae were observed,and the edge of cell and nucleus could not be clearly defined.Meanwhile,the two genes(sod and hsp90) in different tissues were unregulated significantly,indicating that high concentration of ammonia could impair the cellular structures and induce the expression of stress proteins.These results also suggested that sod and hsp90 were suitable biomarkers for ammonia exposure assessment in grass carp.FoundsoftheNationalProgramonKeyBasicResearchProject(2009CB118706

塑造文化传统：华安高山族的舞蹈实践

20世纪90年代以来,高山族舞蹈逐渐被塑造为华安高山族的文化传统。其背后透露出华安高山族、文化权威及地方政府构成的权力关系,在政治经济脉络下,促使舞蹈成为一种社会记忆被标签化,也使高山族人对本民族文化呈现出多重认同感。国家社会科学基金重大项目“台湾原住民族群关系研究”（14ZDB113

铜闪速熔炼过程能效优化模型研究

随着计算机技术的发展,复杂工业过程中积累了大量生产数据,为我们从人工智能的角度进行建模与优化控制提供了数据基础。为了实现铜闪速熔炼过程中的节能减耗,本文提出了一种满足三大工艺指标(冰铜品位,冰铜温度,渣中铁硅比)约束的能效优化模型:首先,我们用最小二乘支持向量机对历史数据进行训练得到三大指标预测模型;然后,我们给出优化数学模型并以三大工艺指标为约束,用改进的粒子群优化算法对能源设定值进行优化。实际结果表明该优化模型能够准确预测工艺指标并实现了一定的节能减耗,对铜闪速熔炼过程的能效优化控制具有一定的指导意义

高品质公租房:国家战略与民生抉择

与以往廉租房、经济适用房的概念不同,本文认为保障房建设可以成为国家中长期经济增长新的引擎,而并非是消极应对民生问题的权宜之计,国家应该取消此前的廉租房和经济适用房政策,将保障房的投资集中于高品质公共租赁房屋的建设方面,并与国家对基础设施的投资进行同等对待。如此,既能解决暂时买不起房又不能享受保障房政策的中低收入夹心层人群的住房需要,又能推动经济的持续平稳发展和解决民生问题,同时还能达到调控房价、整体提升城市建筑品味、防止低水平重复建设、平衡中央和地方经济利益关系、避免过多投机性游资冲击股市和房地产市场等多重目的
