功能材料

功能材料是新材料领域的核心,是国民经济、社会发展及国防建设的基础和先导。它涉及信息技术、生物工程技术、能源技术、纳米技术、环保技术、空间技术、计算机技术、海洋工程技术等现代高新技术及其产业。功能材料不仅对高新技术的发展起着重要的推动和支撑作用,还对我国相关传统产业的改造和升级,实现跨越式发展起着重要的促进作用。

功能材料种类繁多,用途广泛,正在形成一个规模宏大的高技术产业群,有着十分广阔的市场前景和极为重要的战略意义。世界各国均十分重视功能材料的研发与应用,它已成为世界各国新材料研究发展的热点和重点,也是世界各国高技术发展中战略竞争的热点。在全球新材料研究领域中,功能材料约占 85 % 。我国高技术(863)计划、国家重大基础研究[973]计划、国家自然科学基金项目中均安排了许多功能材料技术项目(约占新材料领域70%比例),并取得了大量研究成果。

当前国际功能材料及其应用技术正面临新的突破,诸如超导材料、微电子材料、光子材料、信息材料、能源转换及储能材料、生态环境材料、生物医用材料及材料的分子、原子设计等正处于日新月异的发展之中,发展功能材料技术正在成为一些发达国家强化其经济及军事优势的重要手段。

超导材料

以NbTi、Nb3Sn为代表的实用超导材料已实现了商品化,在核磁共振人体成像(NMRI)、超导磁体及大型加速器磁体等多个领域获得了应用;SQUID作为超导体弱电应用的典范已在微弱电磁信号测量方面起到了重要作用,其灵敏度是其它任何非超导的装置无法达到的。但是,由于常规低温超导体的临界温度太低,必须在昂贵复杂的液氦(4.2K)系统中使用,因而严重地限制了低温超导应用的发展。

高温氧化物超导体的出现,突破了温度壁垒,把超导应用温度从液氦( 4.2K)提高到液氮(77K)温区。同液氦相比,液氮是一种非常经济的冷媒,并且具有较高的热容量,给工程应用带来了极大的方便。另外,高温超导体都具有相当高的上临界场[H c2 (4K)>50T],能够用来产生20T以上的强磁场,这正好克服了常规低温超导材料的不足之处。正因为这些由本征特性Tc、Hc2所带来的在经济和技术上的巨大潜在能力,吸引了大量的科学工作者采用最先进的技术装备,对高Tc超导机制、材料的物理特性、化学性质、合成工艺及显微组

织进行了广泛和深入的研究。高温氧化物超导体是非常复杂的多元体系,在研究过程中遇到了涉及多种领域的重要问题,这些领域包括凝聚态物理、晶体化学、工艺技术及微结构分析等。一些材料科学研究领域最新的技术和手段,如非晶技术、纳米粉技术、磁光技术、隧道显微技术及场离子显微技术等都被用来研究高温超导体,其中许多研究工作都涉及了材料科学的前沿问题。高温超导材料的研究工作已在单晶、薄膜、体材料、线材和应用等方面取得了重要进展。

医用材料

作为高技术重要组成部分的生物医用材料已进入一个快速发展的新阶段,其市场销售额正以每年16%的速度递增,预计20年内,生物医用材料所占的份额将赶上药物市场,成为一个支柱产业。生物活性陶瓷已成为医用生物陶瓷的主要方向;生物降解高分子材料是医用高分子材料的重要方向;医用复合生物材料的研究重点是强韧化生物复合材料和功能性生物复合材料,带有治疗功能的HA生物复合材料的研究也十分活跃。

能源材料

太阳能电池材料是新能源材料研究开发的热点,IBM公司研制的多层复合太阳能电池,转换率高达40%。美国能源部在全部氢能研究经费中,大约有50%用于储氢技术。固体氧化物燃料电池的研究十分活跃,关键是电池材料,如固体电解质薄膜和电池阴极材料,还有质子交换膜型燃料电池用的有机质子交换膜等,都是研究的热点。

五、外文资料翻译 Stress and Strain 1.Introduction to Mechanics of Materials Mechanics of materials is a branch of applied mechanics that deals with the behavior of solid bodies subjected to various types of loading. It is a field of study that i s known by a variety of names, including “strength of materials” and “mechanics of deformable bodies”. The solid bodies considered in this book include axially-loaded bars, shafts, beams, and columns, as well as structures that are assemblies of these components. Usually the objective of our analysis will be the determination of the stresses, strains, and deformations produced by the loads; if these quantities can be found for all values of load up to the failure load, then we will have obtained a complete picture of the mechanics behavior of the body. Theoretical analyses and experimental results have equally important roles in the study of mechanics of materials . On many occasion we will make logical derivations to obtain formulas and equations for predicting mechanics behavior, but at the same time we must recognize that these formulas cannot be used in a realistic way unless certain properties of the been made in the laboratory. Also , many problems of importance in engineering cannot be handled efficiently by theoretical means, and experimental measurements become a practical necessity. The historical development of mechanics of materials is a fascinating blend of both theory and experiment, with experiments pointing the way to useful results in some instances and with theory doing so in others①. Such famous men as Leonardo da Vinci(1452-1519) and Galileo Galilei (1564-1642) made experiments to adequate to determine the strength of wires , bars , and beams , although they did not develop any adequate theo ries (by today’s standards ) to explain their test results . By contrast , the famous mathematician Leonhard Euler(1707-1783) developed the mathematical theory any of columns and calculated the critical load of a column in 1744 , long before any experimental evidence existed to show the significance of his results ②. Thus , Euler’s theoretical results remained unused for many years, although today they form the basis of column theory. The importance of combining theoretical derivations with experimentally determined properties of materials will be evident theoretical derivations with experimentally determined properties of materials will be evident as we proceed with

10kV小区供配电英文文献及中文翻译

在广州甚至广东的住宅小区电气设计中,一般都会涉及到小区的高低压供配电系统的设计.如10kV高压配电系统图,低压配电系统图等等图纸一大堆.然而在真正实施过程中,供电部门(尤其是供电公司指定的所谓电力设计小公司)根本将这些图纸作为一回事,按其电脑里原有的电子档图纸将数据稍作改动以及断路器按其所好换个厂家名称便美其名曰设计(可笑不?),拿出来的图纸根本无法满足电气设计的设计意图,致使严重存在以下问题:(也不知道是职业道德问题还是根本一窍不通) 1.跟原设计的电气系统货不对板,存在与低压开关柜后出线回路严重冲突,对实际施工造成严重阻碍,经常要求设计单位改动原有电气系统图才能满足它的要求(垄断的没话说). 2.对消防负荷和非消防负荷的供电(主要在高层建筑里)应严格分回路(从母线段)都不清楚,将消防负荷和非消防负荷按一个回路出线(尤其是将电梯和消防电梯,地下室的动力合在一起等等,有的甚至将楼顶消防风机和梯间照明合在一个回路,以一个表计量). 3.系统接地保护接地型式由原设计的TN-S系统竟曲解成"TN-S-C-S"系统(室内的还需要做TN-C,好玩吧?),严格的按照所谓的"三相四线制"再做重复接地来实施,导致后续施工中存在重复浪费资源以及安全隐患等等问题.. ............................(违反建筑电气设计规范等等问题实在不好意思一一例举,给那帮人留点混饭吃的面子算了) 总之吧,在通过图纸审查后的电气设计图纸在这帮人的眼里根本不知何物,经常是完工后的高低压供配电系统已是面目全非了,能有百分之五十的保留已经是谢天谢地了. 所以.我觉得:住宅建筑电气设计,让供电部门走!大不了留点位置,让他供几个必需回路的电,爱怎么折腾让他自个怎么折腾去..

哈尔滨工业大学毕业设计(论文) 英文原文(原文也可以直接将PDF版打印) ASSESSING CREDIT OR DETERMINING QUANTITY? THE EVOLVING ROLE OF RATING AGENCIES Lynnette D. Purda* This version: April 21, 2011 Abstract Over the past ten years, credit rating agencies have come under intense criticism from both practitioners and academics, first for their failure to identify problems resulting in bankruptcies at Enron and Worldcom and second for providing overly optimistic ratings for structured finance products. While many investors question the value of rating agencies in light of these criticisms, they have proven remarkably resilient. This paper provides a brief background on how rating agencies secured competitive advantages in evaluating credit quality. It then reviews the empirical evidence on the information content of ratings given these advantages. I argue that the information content of ratings stems from two intertwined sources: 1) information related to credit quality and 2) information related to the firm’s ability to access debt. Based on this evidence, I suggest that the dominant role for ratings today is as a benchmark for financial contracting. In this way, ratings remain influential in establishing the supply and demand of debt securities. 译文 评级机构的发展的作用评估信用还是决定数量? 本文:2011.4.21 摘要 在过去的十年,信用评级机构一直处于来自实践者和学者的激烈的批评中,首先他们未能发现问题,导致安然和世通破产;其次对结构性金融产品提供过于乐观的评级。虽然许多投资者因为这些批评对评级机构的价值提出了质疑,但他们仍然被证明是相当有活力的。这篇文章首先在评估机构如何在信用评级质量中获得竞争优势提供一个简单地背景介绍,然后考虑到这些优势回顾了一些信息内容方面的评级经验证据。个人认为信息内容的评级来自两种交织在一起(错综复杂)的来源:1)和信贷质量相关的信息;2)和公司获取债务资本能力相关的信息。以此为据,我建议当前评级的主导作用是作为基准的金融收缩。以这种方式,在建立债券的供应和需求方面评级仍然是有效的。 - -1

单片机技术发展与应用中英文对照外文翻译文献

(文档含英文原文和中文翻译) 中英文对照外文翻译 单片机技术的发展与应用 从无线电世界到单片机世界现代计算机技术的产业革命,将世界经济从资本经济带入到知识经济时代。在电子世界领域,从 20 世纪中的无线电时代也进入到 21 世纪以计算机技术为中心的智能化现代电子系统时代。现代电子系统的基本核心是嵌入式计算机系统(简称嵌入式系统),而单片机是最典型、最广泛、最普及的嵌入式系统。 一、无线电世界造就了几代英才。在 20 世纪五六十年代,最具代表的先进的电子技术就是无线电技术,包括无线电广播,收音,无线通信(电报),业余无线电台,无

线电定位,导航等遥测、遥控、遥信技术。早期就是这些电子技术带领着许多青少年步入了奇妙的电子世界,无线电技术展示了当时科技生活美妙的前景。电子科学开始形成了一门新兴学科。无线电电子学,无线通信开始了电子世界的历程。无线电技术不仅成为了当时先进科学技术的代表,而且从普及到专业的科学领域,吸引了广大青少年,并使他们从中找到了无穷的乐趣。从床头的矿石收音机到超外差收音机;从无线电发报到业余无线电台;从电话,电铃到无线电操纵模型。无线电技术成为当时青少年科普、科技教育最普及,最广泛的内容。至今,许多老一辈的工程师、专家、教授当年都是无线电爱好者。无线电技术的无穷乐趣,无线电技术的全面训练,从电子学基本原理,电子元器件基础到无线电遥控、遥测、遥信电子系统制作,培养出了几代科技英才。 二、从无线电时代到电子技术普及时代。早期的无线电技术推动了电子技术的发展,其中最主要的是真空管电子技术向半导体电子技术的发展。半导体电子技术使有源器件实现了微小型化和低成本,使无线电技术有了更大普及和创新,并大大地开阔了许多非无线电的控制领域。半导体技术发展导致集成电路器件的产生,形成了近代电子技术的飞跃,电子技术从分立器件时代走进了电路集成时代。电子设计工程师不再用分立的电子元器件设计电路单元,而直接选择集成化的电路单元器件构成系统。他们从电路单元设计中解放出来,致力于系统设计,大大地解放了科技生产力,促进了电子系统更大范围的普及。半导体集成电路首先在基本数字逻辑电路上取得突破。大量数字逻辑电路,如门电路,计数器,定时器,移位寄存器以及模拟开关,比较器等,为电子数字控制提供了极佳的条件,使传统的机械控制转向电子控制。功率电子器件以及传感技术的发展使原先以无线电为中心的电子技术开始转向工程领域中的机械系统的数字控制,检测领域中的信息采集,运动机械对象的电气伺服驱动控制。半导体及其集成电路技术将我们带入了一个电子技术普及时代,无线电技术成为电子技术应用领域的一个部分。进20世纪70年代,大规模集成电路出现,促进了常规的电子电路单元的专用电子系统发展。许多专用电子系统单元变成了集成化器件,如收音机,电子钟,计算器等,在这些领域的电子工程师从电路系统的精心设计,调试转变为器件选择,外围器件适配工作。电子技术发展了,电子产品丰富了,电子工程师的难度减少了,但与此同时,无线电技术,电子技术的魅力却削弱了。半导体集成电路的发展使经典电子系统日趋完善,留在大规模集成电路以外的电子技术日益减少,电子技术没有了往昔无线电时代的无穷乐趣和全面的工程训练。 三、从经典电子技术时代到现代电子技术时代进入 20 世纪 80 年代,世界经济
