教学重点：1)英语科技词语的构成2)科技英语的句法特点教学难点：科技英语的翻译方法实用训练：英译汉：Scientific prediction for the next 30 years汉译英：技术创新1 .Formation of English Technical TermsOne of the most distinctive features of EST is its technical terms，which not only account for a large part of English vocabulary，but also are the must important source of new coined words in modern English，ranging over an extensive area of various fields. A mastery of them will benefit us a great deal in the translation of EST.In terms of form，English technical terms may be classified into three categories, namely, single words (e. g. robot机器人，Internet因特网，etc. ) , compound forms(e.g. feedback反馈，splashdown溅落，etc.)and phrases(e. g. on-and-off-the- road路面越野两用的，anti- armored-fight-vehicle-missile 反装甲车导弹，power transmission relay system送电中继体系，etc. ). Since most of the technical terms come out of the basic rules of word-formation，it's necessary for us to conduct a Brief survey of their formation.1. Affixation 缀合式科技词语Affixation is an important means of coining new English words and technical terms，with prefix and suffix as inseparable elements of the words being coined. The advantage of affixation is evident: it is the most flexible means of forming new woods and its potential of creation is almost boundless，therefore it is extensively used in the formation of technical terms. Besides prefix and suffix of English origin，there are some foreign borrowings，noticeably the Latin ones, e.g. bio-(生命、生物) thermo-(热)，electro- (电),aero-(空气)，carbo- (碳), hydro-(水), -ite(矿物)，-mania(热、狂), etc. If we are familiar with these prefixes and suffixes，many technical terms of such formation can be translated appropriately. The following are some typical examples.miniultrasonicprober =mini +ultra +sonic +prober微型超声波金属探伤仪macrospacetransship=macro +space +trans +ship巨型空间转运飞船teletypesetter=tele +type +setter电传排字机bathythermograph=bathy +thermo +graph海水测温仪barothermograph=baro +thermo +graph气压温度记录器deoxyrihonucleic=de +oxy +ribo+ nucleic脱氧核糖核的photomorphogenesis=photo +morpho +genesis光形态发生2. Compounding复合式科技词语Two or more words combined to form a new word is called compounding. English technical terms formed by compounding generally take three forms: combining with a hypthen (e.g. salt-former卤素，dew-point露点, pulse-scaler脉冲定标器) or without it (e.g. fallout放射性尘埃，hovercraft 气垫船，waterlock水闸，thunderstorm雷暴)，or two or more separate words forming a word combination ( e.g. stem cell 干细胞，optical drive光驱，satellite antimissile observation system卫星反导弹观察系统). Most of such compound words may be translated literally, i.e., Put the Chinese equivalents of the separate elements together and we get the Chinese equivalents of the compound words. Sometimes，however，there are exceptions. For example，bull's eye靶心)，cat-and-mouse航向与指挥的)，dog house(高频高压电源屏蔽罩)，etc.一literal translation in tackling such terms may lead astray. Therefore whenever we are confronted with unfamiliar terms and are not sure of their meaning，we should frequently consult dictionaries of relevant specialties. In many cases some additional explanations are needed to make the original meaning clear and accurate.3 .Blending缩合式科技词语This is a variant of compounding，omitting the latter part of the first word and clipping off the first part of the second word. Sometimes，however, either the first part or the second part of the overlapped word may be clipped to form a new word. This blending of words generally possesses the combined meaning of both; therefore, literal translation is used in translating such terms，with one element modifying the other. Occasionally，a new name is given to the blending.bit=binary+ digit(二进制)位，比特blog=web +log博客brunch=breakfast十lunch早午餐/晚早餐copytron = copy+ electron电子复写技术gravisphere=gravity +sphere引力范围medicare= medical +care医疗保健netizen=net+ citizen网民smog=smoke +fog烟雾telex=teleprinter+ exchange电传4.Acronyms 首字母缩略式科技词语An acronym is a word formed from the initials or other of several words.Acronyms are widely accepted to coin English technical terms. With the rapid development of science and technology，more and more acronyms are being extensively used in various fields. Simple and brief, acronyms sometimes tend to cause ambiguity in meaning. Therefore，it is up to the translator to discern their actual meaning in different contexts.ADP automatic data processing自动数据处理AIDS Acquired Immune Deficiency Syndrome艾滋病EDF'M electronic data processing machine电子数据处理机DINK double income , no kids双收人无子女家庭GSV guided space vehicle制导宇宙飞船Laser light amplification by stimulated emission of radiation激光RAM random access memory随机存取存储器UFO unidentified flying object不明飞行物WWW World Wide Web万维网Sometimes，an acronym happens to be an actual English word，or it may possess more than one meaning. In this case，special attention should be paid to pick out the right equivalent in Chinese.MOUSE minimum orbital unmanned satellite of the earth(仪表载重50公斤以下的)不载人的最小人造地球卫星SALT Strategic Arms Limitation Talks限制战略武器会谈SNAP subsystem for nuclear}auxiliary power辅助(原子)核动力子系统space nuclear auxiliary power空间核辅助能源systems for nuclear auxiliary power辅助核动力系统AS air scoop空气收集器air seasoned风干的(木材)air speed空速，气流速率air station航空站，飞机场American Standard美国标准atmosphere arid space大气层与宇宙空间automatic sprinkler自动洒水车automatic synchronizer自动同步器5 .Proper Nouns 专有名词科技词语Many of the technical terms in English are borrowed from proper nouns such as names of people，places，firms，trade marks，organizations，etc.，normally beginning with a capital letter. In such cases，consulting relevant dictionaries will be of great help . Transliteration is the usual way in translating proper nouns. Sometimes，a label to the corresponding translation is necessary to indicate the nature of the given words.Xerox静电复制(derived from a trademark )IBM System IBM系统(derived from a US corporation)Kuru库鲁病} derived from a place in eastern New Guinea)Alfven wave阿尔文波(derived from the Swedish astrophysicist Hannes Alfven) Chandler's wobble钱得拉波动说(derived from the US astronomer Seth Carlo Chandler )Of course，there are some other forms of technical terms in English. To name a few，Clipping(e. g.“lab”comes from“laboratory”)，Back-formation(e. g.“to lase" comes from“laser")，Coinage(e. g.“quark" in physics)，Functional Shift (e. g. in the phrase“to contract the terminal"，the word“contract" is converted from a noun to a verb)，Borrowing(e. g.“gene" is borrowed from German)，and so on. In whatever circumstances，the discrimination of the original meaning and the contextual analysis are of vital importance. Only when we get an accurate understanding of them，can we put them into Chinese exactly as they actually mean.II .Characteristic Syntax of EST1.More bong and complicated Sentences 大量使用长句EST as a formal style of writing usually consists of more long and complicated sentences. When translated into Chinese，a long sentence may be cut into several parts. For example:The efforts that have been made to explain optical phenomena by means of the hypothesis of a medium having the same physical character as an elastic solid body led，in the first instance，to the understanding of a concrete example of a medium which can transmit transverse vibration but later to the definite conclusion that there is no luminiferous medium having the physical character assumed in the hypothesis.为了解释光学现象，人们曾试图假定有一种具有与弹性固体相伺的物理性的介质。
Ex. 3 (1)1.The voltage across this capacitor is a few hundredths of a volt.该容器两端的电压为零点零几伏。
2.The output of the factory ten years ago was only one fifth what it is now [onefifth its present output].十年前该厂的产量仅是现在的五分之一。
3.The difference between these two values is 13 parts in 104.这两个数值之差为万分之十三。
4.Of the first four chapters, Chapter 3 is the most important.前四章中，第三章最为重要。
／第三章是前四章中最重要的。
5.In this case, current leads voltage by 90o.这种情况下，电流导前电压90°。
6.Now it is necessary for us to solve this equation for that unknown.现在我们需要解出这个方程，求出那个未知数。
7.Upon substitution of these values, it is found that v is equal to the velocity oflight.代入这些值后，即可得v等于光速。
8.In their study of electricity, physicists defined electric field intensity.在电学研究中，物理学家们给出了电场强度的定义。
9.This coefficient remains to be determined.这一系数待定。
10.Here we use two metal balls two meters apart.这里我们使用相距两米的两个金属球。
大学英语科技翻译知识及材料标志用语的表达与翻译1. 用词特征及其翻译标志用语常以独立的词出现。
例如：动词：START 启动STOP 停车PULL 推PRESELECT 预选名词：INLET 入口OUTLET 出口DANGER 危险GLASS 小心玻璃AUTO 自动形容词：OPEN 开（正在营业）CLOSED 关（停止营业）LEFT 左RIGHT 右POISONOUS 有毒物品副词：CLOCKWISE 顺时针COUNTER-CLOCKWISE 逆时针UP 向上DOWN 向下介词：ON 开OFF 关其中以形容词为单位的独立词可译为“……品”。
例如：Dangerous 危险品Perishable 易腐品Explosive 易爆品Radial 放射品Inflammable 易燃品大量使用词组、短语也是科技英语中标志影只用于的特征之一，从而体现出其简洁、客观、信息量大的特点。
例如：HOT WORK IN PROGRESS 正在施工SAFETY FOOTWEAR 穿安全靴NO PHOTOS 禁止拍照NO ADMISSION 禁止入内NO ENTRY 禁止驶入PERSONNEL ONLY 闲人免进HANDS OFF 请勿触碰KEEP CLEAN 保持整洁KEEP DRY 保持干爽Site entrance, dangerous 工地入口，危险Slow, site entrance 工地入口请慢行MAN: 10/03/2007 生产日期：2007年3月10日EXP: 10/03/2008 失效期：2007年3月10日OIL ONCE EVERY SHIFT 每班加油一次2. 句型特征及其翻译标志用语在实际运用中具有指示性、提示性、限制性、强制性等应用功能，经常使用祈使句来实现这些功能。
例如：Handle with care 小心轻放Insert here 由此处插入Do not pass 禁止超车Open here 由此处开启Keep away from moisture 切勿受潮Keep off the grass 勿踏草坪Keep cool 冷藏Protect against heat 注意高温Keep away from heat 切勿受热Stand clear of the door 勿靠（车）门Mind the step 小心台阶Do not turn upside down 切勿倒置Split here 由此处撕开Keep away from fire 切勿近火Keep on deck 甲板装运Stand on end 竖着放Open daily 每天开放在英美国家中，有很多温馨、亲和的提示和请求标志用语，这类标志语多以带祈使语气的单词please开头，因此在翻译成汉语时用语气较温和的“请”字。
科技英语翻译科技英语（English for Science and Technology，简称EST）是从事科学技术活动时所使用的英语，是英语的一种变体（科技文体）。
科技英语自70年代以来引起了人们的广泛关注和研究，目前已发展成为一种重要的英语语体。
本节所讨论的科技英语主要指描述、探讨自然科学各专业的著作、论文、实验报告，科技实用手段（包括仪器、仪表、机械、工具等）的结构描述和操作说明等。
一、科技英语的文体特点科技英语由于其内容、使用域和语篇功能的特殊性，也由于科技工作者长期以来的语言使用习惯，形成了自身的一些特点，使其在许多方面有别于日常英语、文学英语等语体。
这些特点主要表现在词汇和句法两个层面上：（一）词汇层面（1）专业术语多。
专业术语指某一学科领域所特有或专用的语汇，其词义常不为专业外读者所明白，如cryogenics （低温学）、norepinephrine （新肾上腺素）等。
这些专业术语的特点是：a. 词形较长，大多含有源于拉丁语、希腊语和法语的词根、词缀。
这类词语的语义范围较为狭窄，意义较为明确固定，符合科技英语准确明晰的要求。
如：nucleonics （核子学），semisomnus （半昏迷），autoradiography （自动射线照相术），excoriation （表皮脱落）等。
b. 多复合词。
人们常常通过各种构词方法创造出一些复合词来表示科技发展中出现的新事物，如radiophotography （无线电传真），anti-armored fighting vehicle missile（反装甲车导弹）等。
c. 多缩略词。
为使用便利和节省时间，科技英语同经贸英语一样，也有许多缩略词，如cpd （compound化合物），FM （frequency modulation 调频），telesat（telecommunications satellite通讯卫星）等。
（2）准专业术语和词汇多。
科技英语的特点与翻译一、科技英语的特点科技英语（English for science and technology，EST）指与用于科学和技术交流方面的英语口语和书面语。
作为一种重要的英语语体，其特点主要体现在以下几个方面。
1、词汇方面大量使用专业词汇、复合词、缩略词及利用前后缀构成的派生词。
专业词汇意义专一，用来表示明确的含义。
科技词汇多源于希腊语和拉丁语，是因为这两种语言作为英语的重要来源，是世界上成熟最早和最完备的语言中的两种，词汇不再发生词形、词义上的变化，具有稳定性。
2、句子方面多使用长句和被动语态，大量使用名词化结构（nominalization）和非限定动词。
另外，各种成份（如介词短语、形容词及其短语、副词、分词及从句等）作定语并后置，多使用It…that…结构句型、被动结构句型、as结构句型、分词短语结构句型和省略句结构句型等常用句型。
名词化结构有利于行文简洁、表达客观、内容确切，也可使所含信息量增大，尤其是科技英语强调存在的事实，而非个别行为。
不定式短语、-ing分词短语和-ed分词短语这三种非限定动词形式具有齐备的语法功能，可代替各种从句，这样既可缩短句子，行文简练，结构紧凑，又比较醒目。
3、形态方面科技英语在时态运用上有限，多用过去时和现在时。
尤其是多用一般现在时，以表述无时间性的科学定义、定理、公式、现象、过程等。
另外，科技英语多用逻辑性语法词（logical grammatical operators），如表示原因的如because (of)、due (owing) to、as (a result of)、caused by、for等，表示语气转折的如but、however、nevertheless、otherwise、yet 等，表示逻辑顺序的如so、therefore、thus、furthermore、moreover、in addition to等。
4、文体方面科技英语注重行文的连贯（coherence）、清晰（clarity）、流畅（fluency），避免行文晦涩、表露个人感情、过多运用修辞手法等。
By the use of ultrasonic waves, one can find out if there is a flaw in the metal.运用超声波，我们可以找出金属中的裂缝。
Thepositivecharges beingcrowdedupona conductor results intheriseof the potential of the conductor.正电荷聚集在导体上，使导体的电位上升。
He made the assumptionthattheelectronic charge is numerically equal tothecharge on a hydrogen ion.他假定电子与氢离子的电荷数相等。
Biochemistry is the study of the molecular basis of life.生物化学是研究生命分子基础的一门学科。
／生物化学是在分子基础层面研究生命的学科。
They are very familiar with the performance of this type of transistor amplifier.他们非常熟悉这一类型晶体管放大器的性能。
The instrument is used to determine how fully the batteries are charged.这一仪器用来检测电池的充电程度。
My talk today is aboutEinstein’sLaw of Relativity.今天，我的报告是关于爱因斯坦的相对论。
Mercury is appreciably volatile even at room temperature.即使在室温下，汞的挥发性也很强Most isotopes produced artificially are radioactive.大多数人工制造的同位素都具有放射性。
