科技英语写作英文科技论文写作讲座1、 论文标题1 标题不是句子,不要求主、谓、宾齐全,但应注意用词前后次序和用词简练,重点明确。2 标题中尽量避免“study on”,“research on”,“investigation of”之类没有多少实际意义的词组,尤其是在题目较长的情况下。3 标题中不要用缩略语、化学式和专利商标名(在某技术领域内大家熟知的缩写除外)。4 标题不要太长,第一个词和实词的首字母要大写(其他如the、a、an、and和所有介词都小写)。2、 摘要写作注意事项1 摘要基本内容为论文的研究目的(purpose),主要研究过程(procedure),采用的方法(methods)以及主要结论(conclusion)。2 摘要应突出文章的创新和独到之处(what is new and original in this paper?)。3 摘要要使用正规英语和标准术语,避免使用缩写词(除非是大家熟知的如CAD、CAM、IT等)。4 摘要尽可能使用短语,用被动语态,用第三人称。描述作者以往的科研工作可用过去时或现在完成时,但结论用一般现在时。3、 科技论文、项目文件、协议汉译英常用时态1 在论文、项目文件和协议等文件中,提及以前所做的研究工作,而且有具体时间或时间状语时,用过去时或过去完成时。2 论文中实验叙述可用一般过去时。3 论文中的讨论和结论叙述可用一般现在时。4 论文中的讨论和结论叙述可用一般现在时。5 一般真理、定理、公式用一般现在时。6 计划要做的工作、项目活动及预期要达到的目标用一般将来时。4、 英文论文写作应注意的事项1 不能在毫无把握的情况下想当然造字,专业词汇一定要准确,应以英美学者写的原文为参考标准(中国学者写的不足为据!)。2 走出受制于金山词霸。中英文单词的最大区别是具体的中文词(语)只存在一种写法,而译成英文时要根据其确切含义选择最恰当的英文单词(或词组)。比方“潇洒”一词,如果翻英文词典可能又多个词,究竟选哪个呢?(handsome、open-minded、smart、elegant、graceful、natural and unrestrained、noble、cool、in a relaxed state of mind、debonair(轻松愉快)、dashing、vigorous(朝气蓬勃)。3 尽量不连用三个以上的of(可用所属格或从句表示)。4 不用含糊不清的句子,比方某句中的it看不出代表前面哪个词或句子,这在同学们写的论文中屡见不鲜。5 单复数主语应有对应的谓语动词形式,这种类型的错误时常可见,比方data是复数,(单数形式是datum,注意!它又是加工、测量基准的意思。)谓语动词要用复数形式。而games(大型运动会)、proceeding(论文集)、news、United States、United Nations、airlines(航空公司)、headquarters(总部)。看起来是复数,实际上是单数名词。6 论文中不能用过分肯定夸张的句子或词汇(如perfect、best、most desirable、most ideal、createfor the first time、lay a foundation for等)。而应采用would、should、will、surely、certainly、probably、perhaps和provide a technological support for、supply a basis for、conduct a basic research on、carry out a preliminary exploration in、make a preparation work for等婉语。7 要用多个同义词(synonym)代替某个词,不要老是重复用一个词,显得文章乏味。1) 做、开展、进行、从事 do、make、carry out、perform、conduct(research、study、experiment、survey、investigation)2) 制造、制作 make、fabricate、build、manufacture、construct3) 改变、改换、修改、重建、重组 convert、transform、charge、modify、adapt、alter、reform、correct、reconstruct、rebuild、reconfigure、reorganize4) 建议、提出 advise、recommend、suggest、propose、introduce、put forward、present、develop5) 建立 establish、set up、form、construct、formulate、build6) 给、提供 give、offer、provide、supply、furnish7) 改善、改进 improve、enhance、raise、better8) 开发、利用 develop、exploit、take advantage of、make use of、employ、tap、open up9) 验证、证明 verify、prove、check、test、identify、justify、affirm、confirm10)由组成:constitute(department A ,department B constitute the School of Mechanical Engineering;the School of Mechanical Engineering(is composed of、consists of、comprises、is comprised of department A ,department B)注意区别:整体(be composed of、consist of、comprise、be comprised of)分部,而分部(constitute)整体。8. 注意科技文章中一些常用词意上的差别1)manufacture一般指工业上批量的、成熟的有一定规模的制造,而fabricate一般指具有技巧性的,手工方式制造,而且一般是小批量的甚至是单独制作。make是泛指的做和制造。2)transform指根本的转换、变换、改造(常跟into)。convert只指物理形式的变换(比方数模转换),transfer和transmit指传递、传送、发射等(比方heat transfer传热学,data transmission数据传输,power transmission功率传递,TV transmission power电视发射塔,hydraulic transmission液压传动),特别要注意:技术改造是technological transformation,但技术转让却是technology transfer,还有transformation matrix转换矩阵等。communication指信息交流、通讯、联络,transport指交通运输。transit是转运、转口、过渡(phase transition相变,during the transition of the centuries世纪之交,trans-century talent跨世纪人才)。3)Management:企业管理enterprise management、项目管理project management、工商管理business administration、公共管理public administration、数据管理data administration、管理操作员administrative operator4)tool工具,cutter刀具,tooling(无复数形式)工装、模具,device小装置,equipment(无复数形式)设备,instrument仪器、仪表、乐器,(注意,instrument还有手段、方法、证书等意思)installation成套装置设备,apparatus电器、机电设备,appliance家用(电)器具,utensil器皿、厨具,facility(常用复数facilities)设施、设备、工具、机构(例如:sport facilities体育器材、设施),utility公共事业设备(水、电、煤气等),implement工具、器械(农具)。5)element、part零件,component组件、元件、组分、分量(imaginary component虚部,pressure component分压力,structural component结构件),subassembly组合件、机组、分组成、分步装配,assembly总装、装配,machine机器,machine tool机床,machinery机械(总称)。6)trouble麻烦,defect故障缺陷,glitch小毛病,fault人为错误,error计算、测试错误、误差,breakdown故障停机(stoppage diagnosis或fault diagnosis故障诊断),flaw瑕疵、缺陷,mistake理解不当造成的错误,blunder犯大错、失策。(平常只能说:Sorry, its my fault or its my mistake.)7)accuracy精度(machining accuracy加工精度,positioning accuracy定位精度,positional accuracy位置精度,measuring accuracy测量精度,precision精密(precision instrument精密仪器,precision machining精密加工,precision mold精密模具)。8)intensity指强化的程度、力度(比方加大投资力度to increase the investment intensity,提高训练强度to strengthen the training intensity),strength指材料受力后能承受而不被破坏的能力,指力学强度(如疲劳强度fatigue strength,极限强度ultimate strength等),另外一个特殊用法是strengthen,有时也可做优势、实力用。比方on the strength of凭借方面的实力。9)conference正式的会议、讨论会、学术会议、协商会(CPPCC中国人民政府协商会议);convention全国性大会、公约、协定(the Geneva Convention日内瓦公约);congress全国代表大会、美国国会;council政务会、理事会、委员会。如国务院(中)state council,联合国安理会the U.N.

same time、presently、recently、ultimately。第二讲 科技论文中动词的时态和语态特点 英语科技文章中动词常用的时态种类较少,经常使用被动语态,现分别介绍如下:一、时态英语动词共16种时态,其中最常用的只有5种,即一般现在时、一般过去时、现在完成时、一般将来时、现在进行时。科技文章中一般现在时、一般将来时和现在完成时比另外两种更常用些:1 一般现在时一般现在时是科技文章中最常见的时态,主要有三种用法。A 叙述一般过程A scientist observes carefully applies logical thought to his observations and tries to find relationships in data.B叙述客观事实或科学定理Sound travels through the air in waves.Work is equal to the product of force and the distance through which the force moves.C.通常或习惯发生的行为Alternating current is usually supplied to peoples house at 50 cycles per second. 2 一般将来时表示将来发生的行为或情况。Electronic products will become more and more miniaturized because of the increase of inter1 During the part few years,several countries have pooled(开发利用) their resources in order to carry out certain scientific investigation more efficiently.2 The September 11 terrorist attacks have caused great compact on the global economy.二、被动语态在科技文章中被动语态用得十分频繁,这主要有两个原因:第一是谁来执行这些行为和过程并不重要;第二是行为或过程的主体或者没有必要指出,或者根本指不出来。由于摘要语言简明直接,故摘要中大量使用被动语态。三种句型:1:主语修饰语被修饰语2:主语被动语态修饰语3:主语(修饰语)被动语态补足成分例1:A triangulation technique consisting of participant observation 、interviews and questions was used to collect data from 100 engineers and twenty project managers over a two year period.例2:The technical and economic aspects of the problem involved are examined in detail,emphasizing the comparison among different possible alternative solutions. (各种可供选择的解决方案)在科技文章中有带by的短语或句子,但数量不是很多,而且这种带by的短语或句子常常不是指行为的主体,而是行为或过程的方式或工具。1 The insulating substance was severely damaged by the sea water.2 The phenomenon was recognized many years ago and put into use in various applications although it was then poorly understood.3 The spectrum of the antibiotic substance could be determined by testing its effectiveness against various types of bacteria.4 Most of the drags in current use were discovered by accident or trial and error.使用被动语态的另一个原因是用于向后扩展句子,不至于显得头重脚轻。例:In the digital computer the number to be manipulated are represented by sequences of digits which are first recorded in suitable code ,then converted into positive and negative electrical impulses.第三讲 名词化和动词非限定形式light scansthe scanning of the lightto apply forcethe application of forceto translate Chinese into Englishthe translation of Chinese into English例如,名词化既是句子的简化手段,又是句子复杂化的手段。1 Conversion of the energy of a mountain stream into the powerful torque of an electric motor a hundred miles away.2 The General Secretary has prepared a five year survey program which is designed contribution to the development of natural resources by indicating economic and technologically advanced approaches to the exploration and assessment of these resources.动词非限定形式:1 动词不定式动词不定式在句子中可作主语、表语、宾语、定语和状语。1 Although it(形式主语) is difficult (for scientists to know)(to deal with such a large subject 实际主语),the first step is perhaps to consider the main economic difficulties(表语)an underdeveloped on emerging region has to face.2 The refusal to be disturbed or disorganized(干扰和搅乱)by unexpected or apparently adverse occurrences(意外事件),put on the contrary,to be stimulated (激励)by them(定语),has in fact been a marked characteristic of successful investigators.3 Industry everywhere forced rising labor costs and more complex processes, both arising from the determination of human being to achieve a better stand and of living.2 分词作定语、状语、补足语。分词短语起定语从句或状语从句作用,并且和它们交替使用。句子不至于显得单调。1 Thus we may be faced with a society having two basic groups in industrial organization :one consisting of those who carry out the decision of this organizing group.2 It is not easy ,for example ,to explain the processes involved in a computerized control system if the basic algebraic symbols are without meaning.3 Confronted with the many problems presented by,let us say,an active volcano, we many ask:How does volcano work and how is the heart generated?When did volcano first begin to erupt and when is if likely to erupt again?英语科技文章中有时还用独立分词结构,它有两种结构形式:Optimal design 优化设计Digital manufacturing 数字制造(a) 分词有自己的逻辑主语,它和句子的主语不一样The engineering solution is the optimum solution,the most desirable end result taking into account many factors.(b) 介词宾语宾补The volunteers would come into a room where there was a row of five calicles with their doors shut. 动名词:可作主语、定语、表语、宾语,也可以有自己的宾语和。在科技英语中动名词和动名词短语还可作介词和的宾语。2The technique of making the computer carry out a particular task is known as programming ,which involves first breaking the calculation down into a sequence of arithmetic operations and then preparing a series of instructions which cause the discreet computers to carry out the required operations on the stored information in the current order.Operation on对象/with手段多重复合句:This instrument works on the principle that each individual substance emits a characteristic spectrum of light when its molecules are caused to vibrate by the application of the heat ,electricity ,etc. and after studying the spectrum he had obtained on this occasion,Hilebrend reported the gas to be nitrogen.When we look into the matter carefully,we will find that the world we live in presents an endless variety of fascinating problems which excite our wonder and curiosity.语法分析:找谓语后找主语;找连接词。The point I am anxious to make is that the research for models of this kind,the study of their behavior and the relationship of this behavior with the real situations which they seek to represent and the consequential modification of them so as to lead to reliable prediction and then to decisionmaking would not be possible if there were no assistance afforded to the investigator by t
