section2--1-4科技英语阅读与翻译教程文件s e c t i o n2--1-4科技英语阅读与翻译1 Monograph专著1. The general definition of a monographScientific treatises of book length but otherwise variable format prepared by acknowledged experts onspecialized topics for the benefit of others who have specialized in. or who wish to obtain a specialist'sappreciation of, these topics.2. The value of monographs for scientific researchesThe value of monographs lies in the coherence and comprehensiveness of the information and knowledge they contain, which is important to the specialized researchers to whom they are directed and, therefore, to theadvancement of science and engineering generally.3. The qualities of the authors of monographsThe authors of monographs should have exceptional breadth and depth of knowledge, and must be able tocollect, collate, analyze, integrate, and synthesize all relevant contributions to the archival literature of thescientific and engineering journals and to add original material as required.4. The differences between monographs and books of conference proceedings Monographs generally are written by specialists for the benefit of other specialists. Textbooks are pedagogicalworks which, even if written on fairly narrow subjects, aredesigned to serve broader and more juniorreaderships than specialized research communities.5. The differences between monographs and books of conference proceedings Conference papers commonly take the form of premature announcements of new scientific discoveries.Conference proceedings generally have a short shelf life.6. The main components of a monographThe author, title and subtitle, date of publication, dust cover or blurb, content pages, bibliography and index,illustrations, preface and introduction.7. An indication of the book’s su ccessThe number of editions is an indication of the book’s success.8. The function of the blurbIt gives the reader a rapid overview of the contents and approach. It might also say what the book contains and for whom it is written.2 Academic Journal学术期刊1. The general definition of an academic journalAn academic journal is a peer-reviewed periodical in which scholarship relating to a particular academicdiscipline is published.2. The significance of peer-review processThe peer-review process is considered critical to establishinga reliable body of research and knowledge.3. The definition of review articlesReview articles, also called “reviews of progress”, are checks on the research published in journals.4. One difference between original research articles and review articlesUnlike original research articles, review articles tend to be solicited submissions, sometimes planned years inadvance.5. The places where science journals are authoritatively rankedNatural science journals are categorized and ranked in the Science Citation Index, and social science journalsin the Social Science Citation Index.6. The possible quantitative factors to reflect an academic journal’s prestigeThe number of later articles citing articles already published in the journal, the overall number of citations,how quickly articles are cited, and the average “half-life” of articles.7. The financial resources of humanities and social science academic journals Subsidies by universities or professional organizations and advertising fees by advertisers.8. The role of internet in the production of, and access to, academic journalsThe Internet has revolutionized the production of, and access to, academic journals, with their contentsavailable online via services subscribed to by academic libraries or even in a way of open access.33 Organization of a Scientific Paper科技论文的篇章结构1. In most scientific journals, scientific papers include the following sections Summary or Abstract, Introduction, Materials and Methods, Results, Discussion, Acknowledgments.2. The content of Summary or AbstractIt gives a brief background to the topic, describes conciselythe major findings of the paper, and relates thesefindings to the field of study.3. The Introduction section deals with the following two pointsIt describes first the accepted state of knowledge in a specialized field; then it focuses more specifically on a particular aspect, usually describing a finding or set of findings that led directly to the work described in the paper.4. The purpose of Materials and MethodsIts purpose is to describe the materials used in the experiments and the methods by which the experiments were carried out.5. The two ways of organizing ResultsIn some papers, the results are presented without extensive discussion, which is reserved for the followingsection. In other papers, results are given, and then they are interpreted, perhaps taken together with otherfindings not in the paper, so as to give the logical basis for later experiments.6. The purposes of the Discussion sectionThe data in the paper are interpreted; the findings of the paper are related to other findings in the field; thisserves to show how the findings contribute to knowledge, or correct the errors of previous work; some of thelogical arguments are often provided when it is necessary to clarify why later experiments were earned out.7. The reason for combining the Results and DiscussionBecause the data need extensive discussion to allow the reader to follow the train of logic developed in thecourse of the research.8. The difference between the abstracts in Science and those in NatureIn Science, the abstract is self-contained; in Nature, the abstract also serves as a brief introduction to the paper.4 Reading a Scientific Paper科技论文的阅读方法1. The order to understand the major points of the work, you should first read The Abstract.2. Reading the Title and the Abstract serves three purposesFirst, it clarifies whether you in fact know enough background to appreciate the paper. Second, it refreshes your memory about the topic. Third, it helps you integrate the new information into your previous knowledgeabout the topic.3. When reading in a familiar field, you can skim or even skipThe Introduction.4. The three typical codewordsData not shown, unpublished data, preliminary data.5. The poorly written papers are often related to three types of writersThose who are poor writers; those who do not enjoy writing, and do not take the time or effort to ensure thatthe prose is dear and logical; those who are so familiar with the material that it is difficult to step back and seeit from the point of view of a reader not familiar with the topic.6. The t hree characteristics of “bad writing”First, the logical connections are often left out. Second, papers are often cluttered with a great deal of jargon.Third, the authors often do not provide a clear roadmapthrough the paper.7. In better writing, the side issues are dealt with in the following waysThey are relegated to Figure legends or Materials and Methods or clearly identified as side issues, so as not to distract the reader.8. Another problem faced by the readers is that when they seek to understand just the experiment was,they may findThe authors refer back to previous papers; these refer in turn to previous papers m a long chain.。
Unit1 Text A 石油1油,和煤一样,存在于沉积岩中,而且可能由死去很长时间的生物有机体形成。
含有石油的岩石几乎都来源于海洋,所以形成石油的有机物一定是海洋生物,而不是树木。
2 石油,并不是来自于逐渐积聚的木质物质,而可能是来自于逐渐积聚的海洋生物的脂肪物质。
比如浮游生物:大量浮游在海水表层的单细胞生物。
3 有机物的脂肪物质主要由碳氢原子组成,因此并不需要太多的化学变化就可以形成石油。
生物有机体只需在缺氧的条件下沉积到海湾浅水处的淤泥里。
其脂肪不是分解腐烂,而是逐渐积聚,并在深层的淤泥里圈闭起来,进而经过细微的原子重组,最终形成石油。
4 油比水轻,呈液态,会经由上方覆盖的孔隙性岩石向上渗透,在地球上有些地区到达表层,古人将这些表层石油称为沥青、柏油或异庚烷。
在古代和中世纪,这些石油油苗常被看作药品而不是燃料。
5 当然,表层的油苗数量很少。
而石油油藏上方有时覆盖的是非孔隙性岩石。
石油向上渗透抵达该岩石,然后在岩石下方逐渐积聚形成油层。
若在上方的岩石上钻个孔,石油就可以通过该孔向上迁移。
有时压力过大,石油会向高空喷出。
1859年在宾夕法尼亚州,由埃德温·德雷克成功打出第一口井。
6 如果可以发现一个合适的地点(勘探人员已经识别出地下可能圈闭有石油的地层结构),那么就很容易抽取这一液体燃料,这要比派人到地下把大块的固体煤炭砍成小块要容易得多。
而且一旦获得石油,可以通过地上管道运输,而不必像煤一样,由运货车经过繁重的装卸任务来运输。
7 石油便于抽取,易于运输,促进了石油的应用。
石油可以蒸馏成不同的馏分,每种馏分均由特定大小的分子组成,分子越小,该馏分就越容易蒸发。
8 到19世纪下半叶,最重要的石油馏分是由中等大小的分子构成的煤油,它不易蒸发,被用于照明。
9 然而,到19世纪末人们研制出了内燃机。
内燃机是通过在汽缸里将空气与可燃气体混合,产生爆炸来提供动力的。
最便利的可燃气体是汽油——石油的又一馏分,由小分子构成,容易蒸发。
1-2 美国政府计划推出一个重大机构间主动培育,纳米技术称为爆炸性增长的科学兴趣的行为的材料在纳米尺度。
国家科学基金会(基金会),它支持大多数大学的研究,在纳米科学和有可能导致倡议,报告说,它可以基金只有13%的拨款申请,它接收到的领域,而40%的成功率在许多学科在办事处。
3 资金竞争领域中是“绝对凶残,”斯坦说,威廉姆斯,头的基础研究在惠普和积极支持的倡议。
威廉姆斯喜欢的纳米技术纳米技术因为后者已成为柏油的幻想的索赔代表它。
4 “问题是,纳米技术已经过头了,”他说,“我们没有恐惧与厌恶,有些人认为,联想长期愿景的一个厂安置在一个火柴盒。
5 相反,越来越多的认识材料在纳米尺度,在尺寸可比的长度个别分子,可能是把大型产品和过程。
”这是不需要的小东西,它可能是在汽车,”解释克罗可的国家科学基金会的工程,谁主持一个机构间工作组,正在规划的倡议。
”利用纳米技术是非常广泛的,但所有领域,它使用相同的工具和方法。
”6 也许最壮观的应用迄今使用巨磁电阻在1988发现。
在读取头的计算机磁盘驱动器。
相关现象的隧道磁阻不久将允许生产的快速和紧凑的随机存取存储器计算机。
7 但是,正如威廉姆斯指出的,迫在眉睫的纳米技术的应用远远超出了计算机行业。
柯达,他说,发展纳米颗粒称为“染色精”-一个跨之间的粉末颜料和染料分子在印刷图像使用。
轮胎制造商计划和纳米粘土与橡胶轮胎,收尾的聚合物分子和大大延长轮胎的使用寿命。
而五分之四的可能的药物疗法,不可测试的患者因为它们是不溶于水,能产生纳米粒子在水中悬浮,并可能因此成为可行的治疗候选人。
8 所有这种潜力是吸引注意在华盛顿,在支持研究倡议越来越多。
在年度预算准则分发给机构可能,杰克卢主任,管理和预算办公室在白宫,尼尔巷,主任办公室的科学和技术政策,确定纳米技术作为一种成熟的特殊机构间关注。
上月,听证会在众议院和参议院概述了潜在的领域。
9 这一切指向重大加入纳米技术倡议的预算提案的2001财年,,克林顿总统向国会明年二月。
Unit 1 Genetically modified foods -- Feed the World?If you want to spark a heated debate at a dinner party, bring up the topic of genetically modified foods. For many people, the concept of genetically altered, high-tech crop production raises all kinds of environmental, health, safety and ethical questions. Particularly in countries with long agrarian traditions -- and vocal green lobbies -- the idea seems against nature.如果你想在某次晚宴上挑起一场激烈的争论,那就提出转基因食品的话题吧。
对许多人来说,高科技的转基因作物生产的概念会带来诸如环境、健康、安全和伦理等方面的各种问题。
特别是在有悠久的农业生产传统和主张环保的游说集团的国家里,转基因食品的主意似乎有悖自然。
In fact, genetically modified foods are already very much a part of our lives. A third of the corn and more than half the soybeans and cotton grown in the US last year were the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the US this year. The genetic is out of the bottle.事实上,转基因食品已经成为我们生活重要的一部分。
核电与核辐射1986年4月26日,切尔诺贝利核电站的一个反应堆发生爆炸,将相当于400颗广岛原子弹的放射性尘降物散布到整个北半球。
在此之前,科学家对辐射对植物和野生动物的影响几乎一无所知。
这场灾难创造了一个活生生的实验室,尤其是在这个被称为禁区的1100平方英里的区域。
1994年,德州理工大学生物学教授罗纳德·切瑟和罗伯特·贝克是首批获准完全进入该区域的美国科学家之一。
“我们抓了一群田鼠,它们看起来和野草一样健康。
我们对此非常着迷。
”贝克回忆说。
当Baker和Chesser对田鼠的DNA进行测序时,他们没有发现异常的突变率。
他们还注意到狼、猞猁和其他曾经稀有的物种在这片区域游荡,仿佛这里是原子野生动物保护区。
2003年由一组联合国机构建立的切尔诺贝利论坛发表了声明一份关于灾难20周年的报告证实了这一观点,称“环境条件对该地区的生物群落产生了积极影响”,将其转变为“一个独特的生物多样性保护区”。
五年前,贝克和切塞尔在这片区域搜寻田鼠。
Mousseau到切尔诺贝利去数鸟,发现了与之相矛盾的证据。
穆萨乌是南卡罗莱纳大学的生物学教授,他的合作者安德斯·佩普·穆勒现在是巴黎南方大学生态、系统学和进化实验室的研究主任。
他们发现该地区家燕的数量要少得多,而那些存活下来的家燕则遭受着寿命缩短、(雄性)生育能力下降、大脑变小、肿瘤、部分白化病(一种基因突变)以及白内障发病率更高的痛苦。
在过去13年发表的60多篇论文中,Mousseau和Moller指出,暴露在低水平辐射下对该区域的整个生物圈产生了负面影响,从微生物到哺乳动物,从昆虫到鸟类。
包括贝克在内的批评人士对穆萨和穆勒持批评态度。
贝克在2006年与切塞尔合著的《美国科学家》(American Scientist)文章中指出,该区域“实际上已成为一个保护区”,穆萨和穆勒的“令人难以置信的结论只得到了间接证据的支持”。
我们所知道的关于电离辐射对健康影响的几乎所有信息都来自于一项正在进行的对原子弹幸存者的研究,该研究被称为寿命研究,简称LSS。
第一单元什么是罗素悖论?约翰·T·鲍德温,奥利弗·莱斯曼撰胡志国译罗素悖论是建立在这样的实例基础之上的:想象有一群理发师,他们(给所有,而且)只给不给自己刮胡子的人刮胡子。
假设这个集体中有一个理发师,他不给自己刮胡子,那么,按照这个集体的定义,他就必须给自己刮胡子。
但这个集体中的任何理发师都不能给自己刮胡子。
(否则,他就是在给自己刮胡子的人刮胡子了。
)伯特兰·罗素1901年发现的这个悖论是对他的一位数学同行的打击。
十九世纪晚期,戈特洛布·弗雷格试图通过符号逻辑为所有的数学建立一个基础。
他在形式表达式(如x=2)和数学特征(如偶数)之间建立了一种对应关系。
在他的推导中,人们可以随意使用任何特征为后来的特征定义。
罗素在他1903年出版的《数学原理》中公布了自己的悖论,证明了弗雷格系统存在根本缺陷。
在今天看来,这类系统最好通过所谓的集的结构式用集合的概念来描述。
例如,对于由数字4、5、6组成的集体,我们可以描述为:x是一个整数的集体,若用字母n表示这些整数,则n大于3小于7。
对这一集合的描述,在形式上我们写作x={n: n为整数,3<n<7}。
集合的对象不一定是数字。
我们可以设y={x:x为美国男性居民}。
很明显,对x的任何描述都可以填入冒号后的区域。
但罗素(恩斯特·策梅洛也独立地)发现,x={a: a不属于a}会导致矛盾的结论,就像对理发师集体的描述一样。
x自身是否属于x?无论是与否,结论都是矛盾的。
罗素发现这一悖论之后,弗雷格马上认识到他的系统被全盘推翻了。
即便如此,他无法解决这个悖论,而为了绕开这个悖论,人们在二十世纪做了许多尝试。
罗素本人对这一悖论的回答是他的“类型论”。
他分析道,之所以会产生悖论,是因为我们混淆了对数的集合的描述与对数的集合的集合的描述。
于是罗素引入了对象的分级系统:数,数的集合,数的集合的集合,等等。
这个系统曾被作为手段用于对数学基础的第一次形式化,并且在今天的某些哲学研究和计算机分支学科中仍有运用。
