    摘要 Cu–Al–Mn基形状记忆合金具有良好的塑性和形状记忆性能,且成本低并易于切削加工,因此具有极其广阔的应用前景。然而,Cu–Al–Mn基形状记忆合金的临界应力以及疲劳强度都比较低,阻碍了其更多的发展应用。本论文采用合金化方法以Cu–Al–Mn合金为基体,分别添加了Cr、V和Ti元素,制备了Cu–Al–Mn–Cr、Cu–Al–Mn–V和Cu–Al–Mn–Ti三个体系的合金,并逐步采用金相、EPMA、XRD、DSC、压缩、TMA等测试方法,对各合金体系的微观组织结构、相变特性、力学性能和形状记忆性能进行了系统的研究。主要结论如下: (1)Cu–Al–Mn–Cr系合金具有可逆的马氏体相变,...Abstract Cu–Al–Mn-based SMAs have been applied in several practical applications for the advantages of easy fabrication, good shape memory properties and low manufacturing cost. However, the critical stress for stress-inducing martensitic transformation and the fatigue strength of Cu–Al–Mn SMAs are very low, which limit their further practical applications. In this study, three types of C...学位:工程硕士院系专业:材料学院_工程硕士(材料工程)学号:2072014115013

    互联网时代的到来以及计算机智能软硬件的普及,使得我们接触到的文字信息日趋减少,人类已经慢慢地从通过文字获取信息跨越到从图像、声音、感知的多维空间中了解世界。在视觉时代背景下,作为一个全新的设计语言,相比于单纯的文字和图片的简单组合,数字影像具有更强大的唤起能力。随着数字技术的日趋成熟和大众审美水平的提高,人们不再满足于被动接受信息的受众角色,而是渴望在参与和互动中获取信息的同时成为信息的传播者。由于大众对获取信息主动性的追求,数字影像的可交互化设计功能得到越来越多的重视并广泛运用到信息传播的各个领域。 本论文从分析公共信息传播方式的演变出发,探究了公共信息传播走向可交互数字影像时代的发展原因...With the advent of Internet and the popularity of computer intelligence, we have less access to the text information. Human beings have slowly understood the world from images, sound and perception of the multi-dimensional space instead of the text.

    中国在与世界经济接轨的同时,塑造了一批具有中国特色的老字号,如福建福州的“郑兴利”剪刀、“许顺兴”锣鼓、“同利”肉燕、“聚春园”佛跳墙、“鼎鼎”肉松、“大福星”鱼丸;福建厦门的“鼓浪屿”馅饼、“黄金香”肉松……等品牌。但光阴荏苒,岁月流转,再提起这些老字号时,人们只能记起它们曾经有过的辉煌,如今,它们有的风光不再,有的步履蹒跚,有的销声匿迹……时间成就了老字号,时间也让不少老字号黯然失色。 面对福建老字号发展的严峻形势,鉴于福建老字号“经济价值和文化价值的统一体”的特殊身份,本文首先客观地调查分析了当今福建老字号的品牌困境,并以福州、厦门两地市为例,进行深入研究与探讨,希望本文能为有关机构重...A great number of China Time-honored Brands had been set up when China’s economy was being in line of global economy.

    The Relevance Between Corporate Governance and Correction Bulletins for Annuals

    Get PDF
    内容摘要近年来,我国证券市场上颇为频繁的出现着年报“打补丁”的现象,即上市公司在年报发布之后,以临时公告的形式再对其做出更正或补充,而年报补充更正公告通常都表明了先前已经发布的年报中存在着错误或遗漏,更为严重的是,年报补充更正公告可能是上市公司管理者的故意行为——管理层借助这一手段来延缓不利信息的披露时间。实际上,无论哪种情况,“补丁”公告都降低了会计信息的披露质量。公司治理与会计信息披露之间存在着密切的关系,其完善程度制约着会计信息披露的质量,完善的公司治理结构可以减少年报补充更正公告发布的几率,进而提高会计信息披露质量。本文共分为四个部分:1.对国内外学者关于财务重述、“补丁”公告的研究现...Abstract In recent years, the “patch” of annals frequently arose. Listed companies often make supplement or correction to the financial statement they just released. The emergency of complementarity and correction bulletins usually means that there are possible error or neglect in the originally annals, and even badly, it sometimes becomes a good choice of managers to delay the disclosure of ne...学位:管理学硕士院系专业:管理学院企业管理系_企业管理(含财务管理、市场营销、人力资源管理)学号:2005130120

    基于实例机器翻译(ExampleBasedMachineTranslation,EBMT)以相似推理思想为基础,在双语语料库中寻找与源句类似例子,并模仿例子完成译文转换。句子相似度计算是EBMT的一项关键技术,直接影响最终翻译质量。本文吸取了国内外EBMT领域的相关成果,针对目前句子相似度计算存在的不足(模型不完善或需要对语料库进行深加工),提出了综合词汇、短语和句子三个层次的相似度计算模型:1.从词形、词性和语义三个角度探讨词汇相似度;在利用《知网》语义词典计算中改进了义原相似度的计算方法;2.在短语层上,针对旧词序相似度算法的两处不足(相似度函数不对称、未考虑句子长度),改进了词序相似度算...Example Based Machine Translation (abbreviated to EBMT), based on similarity reasoning, tried to find the similar sentence in the parallel bi-language corpora, then generated the result.

    赛珍珠是一位享有盛誉但又颇具争议的作家,评论家认为她是用英语写作但是以中国思维方式来讲述中国故事的美国作家。《大地》是赛珍珠的第二部长篇小说,并在1932年获得普利策文学奖。它以二十世纪初的中国社会作为背景,讲述了王龙一家在各种灾难中挣扎抗争的故事,真实地反映了中国农村的面貌以及人与土地的密切关系。在《大地》之前,西方作家总是以新奇和带有偏见的眼光来看东方或是中国,东方成了西方话语中的“他者”。赛珍珠以自己多年在中国的生活经历和观察,在《大地》中描写了勤劳纯朴的农民,善良坚毅的妇女,丰富多彩的中国习俗以及在动荡的社会里中国农民在土地上与各种自然灾难和战争进行不屈不挠抗争的画面。她改变了西方对中...Pearl S.

    The study of Specific performance

    内容摘要 强制履行是我国《合同法》第107条规定的重要的违约救济形式之一,本文试图对其进行分析。 本文共分四个部分。第一部分,简要介绍了强制履行的概念、性质、理论基础及构成要件,并且阐明,如果损害赔偿可以给予守约方充分补偿,就没有必要选用强制履行。 第二部分,笔者将强制履行与损害赔偿的救济功能作了比较。损害赔偿救济的主要是赔偿守约方的期待利益,只有这样,守约方的利益才不会因为违约而受损。但是,守约方计算期待利益需要承担较多的举证责任,并且期待利益要受到可预见原则的限制。因此,赋予守约方强制履行请求权能更好的保障守约方权利。 但是,在价格波动较大的市场里,当守约方是买方时,允许守约方选择...Abstract Specific performance is one of important liabilities for breach of contract provided in article 107 in Chinese Contract Law.

    优化指数基金采用的是将积极管理型投资与指数化投资两种模式合二为一的“积极指数化”投资管理模式。具体地说,优化指数基金又可以分为增强型指数基金和风格型指数基金。优化指数基金的管理方法不同于传统的被动型指数基金的完全复制法,而是在最少的跟踪误差范围内如何调整成分证券来实现对整个标的指数的优化复制法。本文首先通过对中国目前指数基金现状进行分析,发现我国的优化指数基金主要为增强型指数基金,这与我国证券市场的发展水平有密切关系。我国证券市场属于弱有效市场,市场波动幅度大,被动型的指数基金不能充分把握市场投资机会,因而增强型指数基金具有发展优势。从实际比较来看,我国增强型指数基金的确表现出了它的优势。但这...Optimized Index Fund is managed by the active indexing style which is the combination of active management and indexing management.

    《大地》以二十世纪初的中国社会作为背景,讲述了王龙一家在各种灾难中挣扎抗争的故事,它真实地反映了中国农村的面貌以及人与土地的密切关系。本文采用后殖民主义理论视角,从《大地》的主题、女性地位以及生活文化等方面分析作品的后殖民主义特征,并从赛珍珠的双重文化身份探究了她创作的动机,最后指出《大地》是传播中国文化的伟大作品,它架起了中西方文化交流的桥梁。With the early twentieth century's Chinese society as the background,The Good Earth describes how the family of Wang Lung struggle to fight against numerous disasters,truly reflecting the reality of Chinese rural areas during that period and illustrating the close bond between human and land.By using post-colonialism,this paper intends to analyze post-colonial features manifested in The Good Earth,including the themes,the status of women and the traditional customs.Meanwhile,the writing motive of Pearl S.Buck is examined from exploring her dual cultural identity.Finally,it restates that The Good Earth is a great work to spread Chinese culture and serves as a bridge between the East and the West
