    近年来,商业银行的不良余额及不良率大幅冒升,以中国银行福建省分行为例,2015年末中国银行福建省分行的不良余额已达38.14亿元,较2012年上涨了6倍有余,不良率也在2015年突破2.5%的大关,除此之外,逾期贷款也大幅攀升,资产质量形势不容乐观。除宏观经济环境的影响外,中国银行内部风险管理方面存在的弊端也对资产质量形势的恶化埋下隐患。风险管理人员过度依赖客户经理对授信风险进行识别,缺乏主动有效的工具和手段对授信客户的风险进行识别与预判,无法满足当前经济形势下风险管理的要求。 本文从五个部分来寻求能为中国银行福建省分行风险管理人员带来帮助的风险预警工具。第一部分为引言,阐述本文的选题动机、...The balance and the rate of commercial bank’s bad loans have been increasing for years. Take Bank of China Fujian Branch as example, the amount of its bad loans reaches to 3.8 billion in 2015 which is 6 times more than the number in 2012. The rate of its bad loans has exceeded 2.5% in 2015. So does the overdue loans. In one word the situation of bank’s asset quality is not optimistic.

    自1990s以来,白光发光二极管(whitelightemittingdiode,WLED)的快速发展得益于高亮度GaN基蓝光LED的成功研制。目前,WLED以其高效节能、绿色环保、安全耐用等优点,当仁不让地成为了打造节约型社会环境下照明行业的新宠,被誉为继白炽灯、荧光灯和高强度放电灯之后的第四代照明光源。但当前的WLED不是因缺乏红光成分而导致显色指数偏低,就是因红粉效率较低而导致发光效率偏低。因此,亟需具有高效窄带的红色荧光粉以弥补当前WLED的不足。 本文选择复合氟化物K2MF6(M=Si,Ge)作为荧光粉基质材料,一是因为氟化物素有声子能量低、发光效率高等优点;二是因为Mn4+在该基...Since 1990s, white light emitting diode (WLED) has experienced rapid growth because of the invention of high-brightness GaN-based blue chip. Currently, WLED has become the most promising next generation lighting technology due to its advantages such as high efficiency, energy-saving, environmental friendliness, durability, etc. It has been recognized as the fourth generation lighting source follow...学位:工程硕士院系专业:材料学院_工程硕士(材料工程)学号:2072013115008

    由于通过无线浮标,水下声通信网可接入到现有的立体信息网中,从而形成真正的覆盖全球的立体信息网,故近年来,随着世界各国海洋开发步伐的加快,水下声通信网的研究成为世界各国科学家的热点研究课题。 水声通信网研究面临的主要困难是:海洋声信道的长延时、可用频带有限、严重的时变多途影响、功耗限制、网络安全性等。我国水下数字通信技术的研究起步于八十年代中后期,目前水下通信网络的研究尚未有取得实验成果的报道。因此,迅速开展对水下通信网的研究具有重大意义。 本文研究了水声通信网络的分层结构及拓扑结构,研究了通信网的码分多址(CDMA)系统中几种不同的扩频序列及其相关性,重点对三种不同多载波CDMA接入技术进...Along with the great progress of information technology, the stereo information network which covers the ground, sky, outer space, and ocean has already formed and served for the communication, traffic, resource investigation, national defense all over the world.

    论《牡丹亭》之季节意识

    Get PDF
    汤显祖的《牡丹亭》具有强烈的季节意识,其中提及“春”“秋”等季节之词的章节占总体的80%,“春”“秋”二重唱成为主旋律。《牡丹亭》中的季节不仅仅作为叙事背景被交代,更有机融入了角色的生命意识,是二元对偶的美学呈现、现实与浪漫的重奏、情理之辩的季节意蕴、悲喜剧质的外化彰显。一言以蔽,《牡丹亭》呈现的季节审美与春秋风物,可看作古典文学季节表达的经典范式,值得深入研究。In Tang Xianzu's The Peony Pavilion the strong sense of seasons is so obvious that "spring" and "autumn" and other seasonal words frequently mentioned in the play, which statistically account for 80% in total, therefore, "spring" and "autumn" duet become the main melody. The season in The Peony Pavilion is not only just taken as narrative background but also a part of the life consciousness of the role. It presents dual aesthetic which contains the repetition of reality and romance, embodies the seasonal connotation of emotions and senses, and demonstrates the peculiarity of tragedy and comedy. In a word, the seasonal scenery and aesthetic of The Peony Pavilion can be regarded as a classic seasonal expression in the paradigm of classical literature, which is worthy of further study

    对股票信息风险进行准确的测度无论对资产定价、风险管理还是市场绩效的衡量都有着重要意义。如果一国股票市场的信息风险比较高,或者信息不对称的程度比较严重,无疑会极大地损害市场的公平与效率。各国股票市场监管者都力图能降低股票市场的信息风险或信息不对称的程度,以维护市场的公平和效率。然而,各国股市仍然存在着不同程度的信息风险或信息不对称现象。 那么股票信息风险是否是一种系统性风险?如果信息风险是一种系统性风险,那么投资者持有信息风险高的股票就应该要求获得一个比较高的风险溢酬。而要对信息风险是否是一种系统性风险进行实证检验,首先需要对信息风险进行准确的测度。Easley,Kiefer,O’Hara和P...It is extremely significant to measure information risk of stocks accurately on asset pricing,risk management and the market performance measuring.

    论文人画家与明代戏曲版画

    Get PDF
    明代戏曲版画大繁荣的重要原因之一,就在于大量文人画家的参与,这是时代与个体的双重诉求所呼唤和造就的。本文以陈洪绶为例进行探讨,其绘画意境与戏曲意境达到高妙合一。可以说文人绘制的戏曲版画插图,不仅在质量和意境上升华了戏曲文本,而且直接促进了版画艺术的文人化进程。从整体上看,戏曲版画的文人化倾向也和明代戏曲艺术文人化的发展轨迹不谋而合
