中等分辨率制备分离的 快速色谱技术 W. Clark Still,* Michael K a h n , and Abhijit Mitra Departm(7nt o/ Chemistry, Columbia Uniuersity,1Veu York, Neu; York 10027 ReceiLied January 26, 1978 我们希望找到一种简单的吸附色谱技术用于有机化合物的常规净化。这种技术是适于传统的有机物大规模制备分离,该技术需使用长柱色谱法。尽管这种技术得到的效果非常好,但是其需要消耗大量的时间,并且由于频带拖尾经常出现低复原率。当分离的样本剂量大于1或者2g时,这些问题显得更加突出。近年来,几种制备系统已经进行了改进,能将分离时间减少到1-3h,并允许各成分的分辨率ΔR f≥(使用薄层色谱分析进行分析)。在这些方法中,在我们的实验室中,媒介压力色谱法1和短柱色谱法2是最成功的。最近,我们发现一种可以将分离速度大幅度提升的技术,可用于反应产物的常规提纯,我们将这种技术称为急骤色谱法。虽然这种技术的分辨率只是中等(ΔR f≥),而且构建这个系统花费非常低,并且能在10-15min内分离重量在的样本。4 急骤色谱法是以空气压力驱动的混合介质压力以及短柱色谱法为基础,专门针对快速分离,介质压力以及短柱色谱已经进行了优化。优化实验是在一组标准条件5下进行的,优化实验使用苯甲醇作为样本,放在一个20mm*5in.的硅胶柱60内,使用Tracor 970紫外检测器监测圆柱的输出。分辨率通过持续时间(r)和峰宽(w,w/2)的比率进行测定的(Figure 1),结果如图2-4所示,图2-4分别放映分辨率随着硅胶颗粒大小、洗脱液流速和样本大小的变化。

外文文献翻译 2.5.1译文:看电影的艺术 1930年代中期,沃尔特·迪斯尼才明确以动画电影娱乐观众的思想,动画片本身才成为放映主角(不再是其他剧情片的搭配)。于1937年下半年首映的动画片《白雪公主与七个小矮人》为动画片树立了极高的标准,至今任然指导着动画艺术家们。1940年,这一年作为迪斯尼制片厂的分水岭,诞生了《木偶奇遇记》和《幻想曲>。这些今天成为经典的作品在接下来的二十年中被追随效仿,产生了一系列广受欢迎的动画娱乐作品。包括《小飞象》,《灰姑娘》,《爱丽丝漫游仙境》,《彼得·潘》,《小姐与流浪儿》,他们的故事通常源自广为人知的文学故事。这些影片最不好的地方在于它们似乎越来越面向小观众。 在1966年第四你去死后,他的制片厂继续制作手绘动画影片,但是创作能量衰减,公司转而专注于著作真人是拍电影。然而1989年,对于我们所有孩子来说,动画《小美人鱼》赋予了迪士尼新的生命活力(就像animation这个词本身的定义一样——使有生命活力),从该片开始,出现了一系列令人惊叹不已的音乐动画片。两年后,《美女与野兽》问世,塔尔在制作过程中利用了计算机作为传统手绘技术的辅助手段,这部影片获得了奥斯卡最佳电影奖提名,它是第一部获此殊荣的动画片。更好的还在后面,就想着两部影片一样,后面紧接着出现的众多优秀作品——包括《狮子王》,《阿拉丁》,《花木兰》——延续了迪士尼的经典传统:大胆醒目的视觉效果、精致的剧本,以及我们在所有伟大的电影中,不管是动画还是其他类型中都能找到的普适性主题和出乎意料之处。迪士尼的新版《幻想曲》,又被称为《幻想曲2000》,把原版中的部分片段与新的创作部分糅合在一起。(而且,按照迪士尼管理层的说法,该片是首部在IMAX巨幕影院首映的剧情长片。) 亨利·塞利克执导了蒂姆·波顿出品的两部影片,即《圣诞惊魂夜》和《飞天巨桃历险记》——前者是一部完全原创的定格动画,影片画面有时渗透着无限的恐惧,后者改编自罗纳德·达尔的畅销儿童书,该影片以真人实景拍摄开始。《飞天巨桃历险记》对暴力画面和重大恐惧(比如说,离弃)的表达和处理毫无掩饰,表达的真实感受对成人来说和对儿童一样生动鲜明,而蒂姆·波顿的影片《僵尸新娘》,仅仅从名字上就已经显示出影片内容和该幽默表达的“成人”特

New technique of the computer network Abstract The 21 century is an ages of the information economy, being the computer network technique of representative techniques this ages, will be at very fast speed develop soon in continuously creatively, and will go deep into the people's work, life and study. Therefore, control this technique and then seem to be more to deliver the importance. Now I mainly introduce the new technique of a few networks in actuality live of application. keywords Internet Network System Digital Certificates Grid Storage 1. Foreword Internet turns 36, still a work in progress Thirty-six years after computer scientists at UCLA linked two bulky computers using a 15-foot gray cable, testing a new way for exchanging data over networks, what would ultimately become the Internet remains a work in progress. University researchers are experimenting with ways to increase its capacity and speed. Programmers are trying to imbue Web pages with intelligence. And work is underway to re-engineer the network to reduce Spam (junk mail) and security troubles. All the while threats loom: Critics warn that commercial, legal and political pressures could hinder the types of innovations that made the Internet what it is today. Stephen Crocker and Vinton Cerf were among the graduate students who joined UCLA professor Len Klein rock in an engineering lab on Sept. 2, 1969, as bits of meaningless test data flowed silently between the two computers. By January, three other "nodes" joined the fledgling network.

Computer Program 1 Introduction Computer Program, set of instructions that directs a computer to perform someprocessing function or combination of functions. For the instructions to be carried out, a computer must execute a program, that is, the computer reads the program, and then follow the steps encoded in the program in a precise order until completion. A program can be executed many different times, with each execution yielding a potentially different result depending upon the options and data that the user gives the computer. Programs fall into two major classes: application programs and operating systems. An application program is one that carries out somefunction directly for a user, such as word processing or game-playing. An operating system is a program that manages the computer and the various resources and devices connected to it, such as RAM,hard drives, monitors, keyboards, printers, and modems,so that they maybe used by other programs. Examples of operating systems are DOS, Windows 95, OS\2, and UNIX. 2 Program Development Software designers create new programs by using special applications programs, often called utility programs or development programs. A programmer uses another type of program called a text editor to write the new program in a special notation called a programming language. With the text editor, the programmer creates a text file, which is an ordered list of instructions, also called the program source file. The individual instructions that make up the program source file are called source code. At this point, a special applications program translates the source code into machine language, or object code— a format that the operating system

Animation Animation is the rapid display of a sequence of images of 2-D or 3-D artwork or model positions to create an illusion of movement. The effect is an optical illusion of motion due to the phenomenon of persistence of vision, and can be created and demonstrated in several ways. The most common method of presenting animation is as a motion picture or video program, although there are other methods. Early examples An Egyptian burial chamber mural, approximately 4000 years old, showing wrestlers in action. Even though this may appear similar to a series of animation drawings, there was no way of viewing the images in motion. It does, however, indicate the artist's intention of depicting motion. Early examples of attempts to capture the phenomenon of motion drawing can be found in paleolithic cave paintings, where animals are depicted with multiple legs in superimposed positions, clearly attempting to convey the perception of motion. Five images sequence from a vase found in Iran A 5,000 year old earthen bowl found in Iran.It has five images of a goat painted along the sides. This has been claimed to be an example of early animation. However, since no equipment existed to show the images in motion, such a series of images cannot be called animation in a true sense of the word. A Chinese zoetrope-type device had been

英文翻译 A comprehensive overview of substations Along with the economic development and the modern industry developments of quick rising, the design of the power supply system become more and more completely and system. Because the quickly increase electricity of factories, it also increases seriously to the dependable index of the economic condition, power supply in quantity. Therefore they need the higher and more perfect request to the power supply. Whether Design reasonable, not only affect directly the base investment and circulate the expenses with have the metal depletion in colour metal, but also will reflect the dependable in power supply and the safe in many facts. In a word, it is close with the economic performance and the safety of the people. The substation is an importance part of the electric power system, it is consisted of the electric appliances equipments and the Transmission and the Distribution. It obtains the electric power from the electric power system, through its function of transformation and assign, transport and safety. Then transport the power to every place with safe, dependable, and economical. As an important part of power’s transport and control, the transformer substation must change the mode of the traditional design and control, then can adapt to the modern electric power system, the development of modern industry and the of trend of the society life. Electric power industry is one of the foundations of national industry and national economic development to industry, it is a coal, oil, natural gas, hydropower, nuclear power, wind power and other energy conversion into electrical energy of the secondary energy industry, it for the other departments of the national economy fast and stable development of the provision of adequate power, and its level of development is a reflection of the country's economic development an important indicator of the level. As the power in the industry and the importance of the national economy, electricity transmission and distribution of electric energy used in these areas is an indispensable component.。Therefore, power transmission and distribution is critical. Substation is to enable superior power plant power plants or power after adjustments to the lower load of books is an important part of power transmission. Operation of its functions, the capacity of a direct impact on the size of the lower load power, thereby affecting the industrial production and power consumption.Substation system if a link failure, the system will protect the part of action. May result in power outages and so on, to the production and living a great disadvantage. Therefore, the substation in the electric power system for the protection of electricity reliability,

的人》2004年在第57届戛纳电影节上被提名。《纯真》是到《攻壳机动队》(1995)的续集,在美国的Billboard影片排行榜上名列第一。宫崎骏的《千与千寻》2003年在第75届奥斯卡奖项上荣获奥斯卡动画长片奖,同时在2002年柏林电影节金熊奖上再次获奖和证明日本是生产世界一流动画的国家。据说许多美国和亚洲动画师想要制作日本的动漫作品,这表明日本动画被领先的专业人士认可。《千与千寻》的商业成功,同时表明在全球公众的日本动漫的优点和国际竞争力。世界已经明确看好日本动漫具有巨大的商业潜力。 尽管如此,业界还没有转移的态势,足以应付海外的一致好评。展望未来,日本动漫产业不仅要扩大海外,它也必须制定必要的生产/配送系统和人员,利用对动画片和其他内容的全球商业机会。事实上生产系统已经成立,但业内人士仍然具有在国内/海外发行和权利上有许多突出的弱点,如在一般的国际许可和业务专长。在发展领域的人员,动画师没有一个适当的高社会地位,所以对其他行业和国家,例如人员外流,已成为一个大问题。 2、多变的市场规模 日本国内的动漫市场大致可分为三类: 正片长度的电影 电视节目 上述视频和DVD两个版本外,还有原作品 据媒体发展研究所透露,在2003年日本的动漫市场销售额下降了10.4%至一千九百十二亿日元,包括动画电影的票房收入,电视动画制作费,销售、出租录像带和DVD产品的利润。这是在两年内(图1)的首次下降。在2001年和2002年实现实质性成果主要是由于2001年《千与千寻》成功的票房(30.4亿日元)然

博物馆 外文翻译 外文文献 英文文献

第一篇: 航空博物馆与航空展示公园 巴特罗米耶杰·基谢列夫斯基 飞翔的概念、场所的精神、老机场的建筑---克拉科夫新航空博物馆理性地吸取了这些元素,并将它们整合到一座建筑当中。Rakowice-Czyzyny机场之前的旧飞机修理库为新建筑的平面和高度设定了模数比例。在此基本形态上进一步发展,如同裁切和折叠一架纸飞机,生成了一座巨大的建筑。其三角形机翼是由混凝土制成,却如同风动螺旋桨一样轻盈。这个机翼宽大通透,向各个方向开敞。它们的形态与组织都是依据内部功能来设计的。机翼部分为3个不平衡的平面,使内外景观在不断变化中形成空间的延续性,并且联系了建筑内的视觉焦点和室外的展览区。 新航空展示公园的设计连接了博物馆的8栋建筑和户外展览区,并与历史体验建立联系。从前的视觉轴线与通道得到尊重,旧的道路得到了完善,朝向飞机场和跑道的空间被限定出来。每栋建筑展示了一个主题或是一段飞行史。建筑周围伸展出巨大的平台,为特殊主题的室外展览提供了空间。博物馆容纳了超过150架飞机、引擎、飞行复制品、成套的技术档案和历史图片。这里的特色收藏是飞机起源开始的各种飞行器,如Jatho1903、Grade1909、莱特兄弟1909年的飞机模型和1911年的鸽式单翼机。 The first passage: Museum for aviation and aviation exhibition park Bartiomiej Kislelewski The idea of flying, the spirit of place, the structure of the historic airfield – the new Museum of Aviation in Krakow takes up these references intellectually and synthesizes them into a building. The old hangars of the former airport Rakowice Czyzyny set the modular scale for the footprint and the height of the new building. Developed from this basic shape, as if cut out and folded like a paper airplane, a large structure has been generated, with triangular wings made of concrete and yet as light as a wind-vane propeller. The wings are generously glazed and open in all directions. Their form and arrangement depend on the interior uses. In the floor plans of the wings, the three offset

机械设计外文翻译(中英文)

盛年不重来,一日难再晨。及时宜自勉,岁月不待人。 机械设计理论 机械设计是一门通过设计新产品或者改进老产品来满足人类需求的应用技术科学。它涉及工程技术的各个领域,主要研究产品的尺寸、形状和详细结构的基本构思,还要研究产品在制造、销售和使用等方面的问题。 进行各种机械设计工作的人员通常被称为设计人员或者机械设计工程师。机械设计是一项创造性的工作。设计工程师不仅在工作上要有创造性,还必须在机械制图、运动学、工程材料、材料力学和机械制造工艺学等方面具有深厚的基础知识。如前所诉,机械设计的目的是生产能够满足人类需求的产品。发明、发现和科技知识本身并不一定能给人类带来好处,只有当它们被应用在产品上才能产生效益。因而,应该认识到在一个特定的产品进行设计之前,必须先确定人们是否需要这种产品。 应当把机械设计看成是机械设计人员运用创造性的才能进行产品设计、系统分析和制定产品的制造工艺学的一个良机。掌握工程基础知识要比熟记一些数据和公式更为重要。仅仅使用数据和公式是不足以在一个好的设计中做出所需的全部决定的。另一方面,应该认真精确的进行所有运算。例如,即使将一个小数点的位置放错,也会使正确的设计变成错误的。 一个好的设计人员应该勇于提出新的想法,而且愿意承担一定的风险,当新的方法不适用时,就使用原来的方法。因此,设计人员必须要有耐心,因为所花费的时间和努力并不能保证带来成功。一个全新的设计,要求屏弃许多陈旧的,为人们所熟知的方法。由于许多人墨守成规,这样做并不是一件容易的事。一位机械设计师应该不断地探索改进现有的产品的方法,在此过程中应该认真选择原有的、经过验证的设计原理,将其与未经过验证的新观念结合起来。 新设计本身会有许多缺陷和未能预料的问题发生,只有当这些缺陷和问题被解决之后,才能体现出新产品的优越性。因此,一个性能优越的产品诞生的同时,也伴随着较高的风险。应该强调的是,如果设计本身不要求采用全新的方法,就没有必要仅仅为了变革的目的而采用新方法。 在设计的初始阶段,应该允许设计人员充分发挥创造性,不受各种约束。即使产生了许多不切实际的想法,也会在设计的早期,即绘制图纸之前被改正掉。只有这样,才不致于堵塞创新的思路。通常,要提出几套设计方案,然后加以比较。很有可能在最后选定的方案中,采用了某些未被接受的方案中的一些想法。

文献信息: 文献标题:Creative China must find its own Path(中国要有自己的创新之道) 国外作者:Justin 0'Connor 文献出处:《Zhuangshi》, 2009, 199:1-4 字数统计:英文2082单词,10526字符;中文3519汉字 外文文献: Creative China must find its own Path It is commonly said that China needs to ‘catch-up’ with ‘the west’ or the ‘developed world’. This phrase implies a singular path; there may be short cuts and ‘late-comer advantages’ but the destination –a modern, developed country –is the same. But just when it seems China is within touching distance, the ‘developed world’ changes the definition of what it is to be ‘developed’ and puts more obstacles in the path of those trying to catch-up. In English we call this ‘moving the goal-posts’. After manufacturing, services and high-technology seemed to present clear goals for China, the cultural creative industries arrive as the new ‘value-added’ product and service sector, posing yet more problems for the country’s policy-makers. Many in the West have argued that China will take a long time to catch-up in these areas and that this provides a new source of competitive advantage to the West. Indeed, for some, the absence of a competitive cultural creative industries sector is evidence that China is not, and maybe can never be, fully ‘developed’. Much of this can be dismisse d as another example of the West’s superiority complex; however, there can be no doubt that the cultural creative industries present great possibilities but also great challenges for China. These industries – from visual and performing arts, to recorded music, film and TV, to digital animation and new media services, through to fashion, design and architecture – are highly creative and

It should be said it is a common scientific and technological development of a comprehensive results, for the socio-economic development of a significant impact on a science and technology. It attributed the development of all countries in the Second World War to strengthen the economic input on strengthening the country's economic development. But they also demand the development of the productive forces the inevitable result of human development itself is the inevitable result then with the development of humanity, people constantly discuss the natural process, in understanding and reconstructing the natural process, people need to be able to liberate a slave. So this is the slave people to be able to replace the complex and engaged in heavy manual labor, People do not realize right up to the world's understanding and transformation of this technology as well as people in the development process of an objective need. Robots are three stages of development, in other words, we are accustomed to regarding robots are divided into three categories. is a first-generation robots, also known as teach-type robot, it is through a computer, to control over one of a mechanical degrees of freedom Through teaching and information stored procedures, working hours to read out information, and then issued a directive so the robot can repeat according to the people at that time said the results show this kind of movement again, For example, the car spot welding robots, only to put this spot welding process, after teaching, and it is always a repeat of a work It has the external environment is no perception that the force manipulation of the size of the work piece there does not exist, welding 0S It does not know, then this fact from the first generation robot, it will exist this shortcoming, it in the 20th century, the late 1970s, people started to study the second-generation robot, called Robot with the feeling that This feeling with the robot is similar in function of a certain feeling, for
