from,constructed,formulated,elabrated,第37页,第37页,科技论文写作中词汇,科技论文中大量使用各学科专门术语，还经常使用一些日常语言中不怎么使用书面词汇，主要是突出科技英语正式、庄严语体特性，同时应避免使用浮华、带有感情色彩词语，当然并不是说科技论文中不使用普通词汇。另外，一些动词短语往往由正式动词替换，以求简练。,第38页,第38页,科技论文写作中词汇,普通英语词汇,科技英语中非技术词,about approximately,ask inquire,begin commence,change transform,finish complete,get obtain,have possess,method technique,quick rapid,similar identical,use employ,utilize,enough sufficient,by which whereby,in which wherein,in the end eventually,第39页,第39页,科技论文写作中词汇,动词短语 正式动词,turn on complete,take in absorb,put up erect,put in add,wear away erode,take away remove,use up consume,exhaust,look over examine,keep up maintain,bring out introduce,第40页,第40页,科技论文写作中词汇,注意词汇正确搭配，希望在阅读文献时注意摘录。e.g.,Three-phase slurry reactor has several advantages,over,fixed-bed reactor.,应避免口语中使用词语，使句子比较稳重。,lots of(a lot of)many,quite a few several,普通在科技论文中不使用生活或新闻报道中使用缩略词语。,lab laboratory,auto automobile,ad advertisement,第41页,第41页,科技论文写作中词汇,趋于用名词来表示动作。,Mass-transfer is compared with heat-transfer.,A,comparison,of mass-transfer with heat-transfer is made.,The performance of this flow meter is analyzed.,An,analysis,of the performance of this flow meter is made.,E,gives an indication of,(indicates)activation energy.,Fig.2-6,provides an illustration of,(illustrates)the effect of reaction temperature on the yield.,第42页,第42页,句子特性,句子长，结构严谨。可采用三种手段处理句子。,（1）with短语、形容词短语、分词短语等,（2）with结构、分词独立结构等,（3）各类从句，尤其是定语从句,第43页,第43页,句子特性,With,(1)“with+一些抽象名词”等效于这些名词所相应副词，但语调更强。,These experiments should be done,with care,.,This parameter can be measured,with accuracy,.,(2)with 与vary,change,increase,decrease等动词连用时可表示“伴随”之意。,The conductivity of a semiconductor varies,with temperature,第44页,第44页,句子特性,(3)将with用在句首可表示“对于，有了”等意思。,With the alternating current,things are different.,对于交流电来说，情况就不同了。,With radar,we can see distant objects.,有了雷达，我们能够看到远处物体,(4)可组成一个“with结构”，其应用尤其广泛。,第45页,第45页,句子特性,“with结构”,指下列形式：,分词,介词短语,形容词（短语）,with+名词（或代词）副词,不定式短语,名词（短语）,第46页,第46页,句子特性,作状语,写作重点：处于句首表示条件、时间和原因，,处于句尾表示附加阐明、方式、条件。,With friction present,a part of power has been lost as heat.,由于存在摩擦，因此一部分功率作为热损耗掉了。,Both practical design techniques and theoretical problems are covered,with emphasis on general concepts.,（本书）既讲了实际设计办法，同时也讲述了理论问题，而侧重点则放在普通概念上。,第47页,第47页,句子特性,Each planet revolves around the sun in an elliptical orbit,with the sun at one focus of the ellipse,.,每颗行星在椭圆轨道上绕太阳运营，而太阳处于椭圆一个焦点上。,All present states are stable,with no inputs present,.,在没有输入情况下，当前所有状态均是稳定。,The second term is evaluated similarly,with Z a function of,y,alone.,第二项能够同样计算出来，只要把,Z,仅作为,y,函数就行。,第48页,第48页,句子特性,An initial analysis of the device parameters has been made,with satisfactory results.,A brief introduction to the principles of a CSTR is given,with emphasis on reactor model,.,作定语,This is an inequality,with zero on the right,.,这是一个右边为零不等式。,第49页,第49页,经常使用一些句子表示方式,（1）主语系动词表语（名词）,这种句型所表示语调比用形容词作表语句型更强烈。,This is,too small a signal,.,This is,so sensitive an instrument,that it can measure the slight change in pressure,.,（2）采用“主谓宾”句型代替汉语中“主系表”句型。,撰写论文时受汉语影响，很不习惯使用这种结构。,第50页,第50页,经常使用一些句子表示方式,“Have”句型,即句中谓语动词为have。凡在汉语句中似乎找不到动词普通可使用这一句型，它主要用于表示尺寸、大小、比较、优缺点等概念。,A.表示尺寸、大小、长度、高度,“Something+have+a(an)+表示大小名词+of+数量”,The wall of the reactor has a thickness of 1 centimeter.,This pipe has an approximate length of 50 meters.,第51页,第51页,经常使用一些句子表示方式,B.表示比较,“something A+have+比较级（或as+形容词原级）+要比较名词+than+something B”,This substance has a more complicated chemical structure than that one.,Alcohol does not have as high a boiling point as water(does).,第52页,第52页,经常使用一些句子表示方式,C.表示优缺点,“主语+have+优缺点名词”,The reactor has the advantages of simple structure and high efficiency.,The three-phase slurry reactor has the disadvantage of its height.,第53页,第53页,经常使用一些句子表示方式,（3）采用BE句型。这一句型我们也不是十分熟悉。,A.表示大小、数量,Something+be+数量+表示大小形容词（或in+表示大小名词）,The distillation column is 20 meters high.（或in height）,These perforated plates are 2 centimeters thick.,当然依据语法条文，也可写成下列句型，中国人尤其习惯这一句型,。,The height of the distillation column is 20 meters.,第54页,第54页,经常使用一些句子表示方式,B.表示比较,物A+be+比较级（或as+原级）+in+要比较对象+than(as)+物B,This substance is more complicated in chemical structure than that one.,Alcohol is not as high in boiling point as water(is).,中国人习惯,The chemical structure of this substance is more complicated than that of that substance,第55页,第55页,经常使用一些句子表示方式,(4)不少情况下使用静态结构来表示状态、特性、情况以取代采用行为或过程句法结构。,使用“系动词+表语”结构。表语普通是形容词，有时也可是名词或介词短语。,The flask,is breakable,(can be broken).,This method,is applicable,(can be applied)to process simulation.,The resistance of mass-transfer,is ignorable,(can be ignored).,第56页,第56页,经常使用一些句子表示方式,A hyperbola,is indicative,(indicate)of an inverse proportion.,Eq.1,is an illustration,(illustrates)of global kinetics model.,The problem,is under consideration,(is being considered).,This product,is in great demand,(is needed by a great many companies).,第57页,第57页,经常使用一些句子表示方式,(5)不少情况下用短语代替从句，尤其是代替状语从句和定语从句，使句子更为紧凑，避免结构松散。,A.用介词短语代替状语从句。,After the experiments have been completed,After(At or ON)the completion of the experiments,If the temperature is greater than 60,At a temperature greater than 60,第58页,第58页,经常使用一些句子表示方式,If the temperature is decreased by 10,For a decrease in temperature of 10,If the pressure remains constant,At constant pressure,B.用作主语名词短语代替表示条件、原因、目的状语从句。,If the results are analyzed,it can be shown that ,=An analysis of the results shows that,第59页,第59页,经常使用一些句子表示方式,Since there is no atmosphere in space,scientists could make pure drugs there.,=The absence of atmosphere in space would enable scientists to make pure drugs there.,If experimental data are compared with the calculated ones,it can be shown that,=A comparison of experimental data ,第60页,第60页,经常使用一些句子表示方式,(6)限定性短语或从句,按照传统语法，当你希望从一组事物中，把其中一个(一部分)尤其区分出釆，以“限定说明”其与其它部分不同之处时，要采取“that”(而不是”which”)，也就是说，that引出是实质性信息。这个短语或从句就成了主句或句子必需成份，它们是限定性短语或从句。没有这个短语或从句，主句或句子就失去了基本含义。,第61页,第61页,经常使用一些句子表示方式,Comparison will be restricted to acetylene compounds,that,(不用,which,)have the same functional end groups.,Reaction leading,to the desired products,are shown in Scheme 1.,(7)非限定性短语或从句,当一个短语或从句即使能传达信息，但并不是主要而只是附加信息，那么它们称为非限定性短语或从句。也就是，当它们被删除时，主句没有失去其主线含义。非限定性从句引入采用“which”，非限定性短语和从句与句子其它部分用逗号隔开。,第62页,第62页,经常使用一些句子表示方式,All the chemicals,that,lost labels must be labeled as waste,which,will be shipped out and destroyed by the Waste Task Unit.,Melvin Calvin,who won the Nobel Prize in 1961,elucidated the biochemical pathways in photosynthesis。,第63页,第63页,经常使用一些句子表示方式,注意：,1、应模仿国外科技文献中一些固定、地道说法及特殊句型。,The device is small in size.,Emphasis is put on what is described in this chapter.,This device is characterized by small size,light weight,high efficiency and low cost.,These rectors are(of different sizes)different in size.,第64页,第64页,经常使用一些句子表示方式,2、在表示“办法是”时，往往不采用“The method for is”句型，而是采用“is found(determined,increased,achieved,solved,calculated,reduced,obtained,satisfied,separ
