The Bessemer Process(贝塞麦炼钢法/酸性转炉炼钢法) uses a furnace called a “converter”. The outside of the converter is made of steel plates. The inside is lined with bricks. The converter is tipped on to its side and the charge of molten iron is poured into the top. Then the converter is put upright again. A blast of air is blown through holes in the base of the converter. 有一种高炉称为“转炉”，采用酸性转炉法。转炉的外壳 由钢板制成。内部用耐火砖衬砌。把转炉向一侧倾转后， 从炉顶上把铁水倒入炉中。再把炉子转回直立位置。从炉 子底部的孔中把空气吹入炉中。

• 《Titanic》：
Jack: Listen, Rose. You're going to get out of here. You're going to go on. You're going to make lots of babies, and you're going to watch them grow. You' re going to die and old, an old lady in her warm bed, not here, not this night, not like this. Do you understand me?
Word building（构词法）
• A common way of making new words in English is by adding standard combinations of letters to existing words, either at the beginning (prefixes) or at the end (suffixes).
- acryl-意为“丙稀”, -nitrile意为“腈”。通过词素语义 的分析“polyacrylonitrile”一词的汉意就弄清楚了,即“聚丙 烯腈”。

介词的转译
句子成分转换的译法
所谓句子成分转换的译法，是把句子的 某一成分（如主语）译成另一成分（如宾语 等）。在多数情况下，词类转译必然导致句 子成分的转译，例如：当英语的动词转译为 汉语的名词或副词时，该动词的谓语成分也 就相应地转译为汉语的主语．宾语或状语等。 成分转换的目的是使译文通顺，符合汉 语习惯。

后置定语多
后置定语是位于其所修饰的名词之后的定语，汉语常用前 置定语或多个简单句来说明某概念或某术语，而科技英语 则更多地使用后置定语。 If we now visualize a region of space filled with a tremendous number of charges separated by minute distances. We see first that the field cannot vary with y or with z, and then that the y and z components arising from differential elements of charge symmetrically located with respect to the point at which we wish the field will cancel.

i、后置定语译为前置定语
在英语中，有时会出现两个单个词同时修饰同一 名词的情况。这时一般是形容词或名词性修饰词 在被修饰词前，分词性修饰词在被修饰词之后。
例如：
The heat energy produced is equal to the electrical energy utilized. 所产生的热能与所使用的电能相等。
设计电机
同一的 惟一的

(1) All the metals are good conductors because there is a great number of free electros in them. (2) The unit smaller than a meter is called a decimeter. (3) The Industrial Revolution started in England at the second half of the 18the century. (4) The theory is of great importance that the hotter a body is, the more energy it radiates. (5) The three gas laws are true of gases as well as of air.
2、状语倒置
• ii、状语语序的倒置 例如： I was working with my two assistants (方式) in our laboratory(地点) at that moment(时间). 我那时（时间）正在实验室（地点） 与两个助手 一道（方式）工作。

科技英语翻译技巧

科技英语的词汇翻译
句子是由词汇组成，准确地理解词义是正确翻译句子的 基础。英语词汇非常丰富，在长期的演变中还吸收了大量外 来语，构词复杂，它们在语义范围、修辞特色等方面常常是 有区别的。因此，翻译时要仔细推敲恰当地表达。 英语一词多义的现象非常突出，如point就有20多个词 义：点，标点，地点，尖端，时刻，程度，要点，细目，意 义，目的，用途，切点（数），穴位（医），短促音调 （音）等。介词“of”在牛津大辞典上有64个词义。
科技词汇具有八种特征： 1. 确切性（accuracy） 2. 单义性（monosemy） 3. 系统性（systematization） 4. 语言的正确性（linguistically correct） 5. 简明性（consciences） 6. 理据性（motivation） 7. 稳定性（stability） 8. 能产性（productivity）
Байду номын сангаас
3. 一词多译法 英语原文中的同一个词，汉译时可有多种表达，这就是 一词多译现象。它主要有以下几种情况。 ⑴多主一表，表语一词多译 Tensile strength, elasticity, tear and abrasion resistance and compression set are relatively low. 抗拉强度较低，弹性及抗撕裂与耐磨性较差，压缩永久变 形较小。（原句中表语是relatively low, 而主语分别是tensile strength, elasticity, tear and abrasion resistance and compression） 若原句译成“抗拉强度、弹性、抗撕裂、耐磨损性与压 缩永久变形较低”，就语义不通。
⑵ 一动多宾，动词一词多译 You cannot build a ship, a house, or a machine tool if you do not know how to make a design or how to read it. 如果你不知道怎样制图或怎样识图，你就不可能建船、 盖房或造机床。（原句中动词build之后有三个宾语a ship, a house, or a machine tool, 相 应 地 ， 动 词 build 分 别 译 成 “建”、“盖”和“造”。） ⑶一动多宾，宾语一词多译 The current increases faster than resistance decreases, leading to more heating and less heat radiation and resistance. 电流的增大比电阻的下降要快，这便导致发热增加，热 辐射减弱，热传导阻力减小。

电能可储存在由一绝缘介质隔开的两块金属极板内。这样的装 置称之为电容器，具有储存电容的能力。电容的测量单位是法 拉。
三、非限定动词 由于科技文章要求书写简练、结构紧凑，因而常常使用
分词短语代替定语从句；使用分词独立结构代替状语从 句或并列分句；使用不定式代替各种从句，“介词+动 名词短语”代替定语从句或状语从句。这样，既可缩短 句子，又比较醒目。
A direct current is a current which flows always in the same direction.
A direct current is a current flowing always in the same direction.
直流电是一种总是沿同一方向流动的电流。
我们可将电能储存在由一绝缘介质隔开的两块金属极板内。我 们称这样的装置为电容器，它可以储存电容。我们用法拉为单 位来测量电容。

二、词的引申
所谓词的引申，指的是在一个词所具有的基本词义的 基础上，进一步加以引申，选择比较恰当的汉语词来 表达，使原文的思想表现得更加准确，译文更加顺畅。 如heavy的基本词义是“重”，
heavy current heavy traffic heavy industry
(工业)电视摄像机 再如：base在下列各句中具有不同的意义。
The lathe should be set on a firm base.
车床应安装在坚实的底座上。

As we all know, a base reacts with an acid to form a salt.
众所周知，碱与酸起反应生成盐。
在这种情况下，炉温就升高。

二、转换成汉语名词
1.某些英语动词的概念难以直接用汉语的动词表达，翻 译时可转换成名词。
Such materials are characterized by good insulation and high resistance to wear. 这些材料的特点是：绝缘性好，耐磨性好。
If a box weighs 10 kilograms, an upward force of 10 kilograms must be exerted to lift it. 假定箱子的重量是10公斤，就必须施加10公斤向上 的力才能把它举起来。

《专业英语（制药工程）》【科技英语的常用句型和翻译技巧】一、概述1. 翻译的要求The Criteria of Translation：信、雅、达2. 科技英语词汇（上节课已经介绍）3. 科技英语句子的特点二、科技英语常用句型及翻译1. 被动语态1）被动语态的常用原因常用被动语态主要见于以下几个方面：①不必或无法说出主动者For a long time aluminum has been thought as an effective material for preventing metal corrosion.长期以来，铝被当作一种有效的防止金属腐蚀的材料。

►The book has already been translated into many languages.②强调行为对象，而非行为者，将行为对象作为句子的主语Three machines can be controlled by a single operation.三台机器能由一个操作者操纵。

►The work must be finished at once.③为了更好的联系上下文►They are going to build a library here next year. It is going to be build beside the classroom building.2）被动语句的翻译方法（1）仍译为被动句最常见的是在谓语前加上助词“被”，也可使用“受到，遭到，得到，叫，称，让，给，加以，为……所”等句式。

偶尔也可不加任何词直接译出。

We remember how air can be made into a liquid. If the liquid is warmed again, it “boiled”and turns back into a gas.我们记得是如何把空气制成液体的。

如果给这种液体重新加热，它“沸腾汽化”，就又还原成气体。

►Every thing is built up of atoms.►The process by which energy is changed from one form into another is called the transformation of energy.Water is usually considered as being a compound of two elements.（2）译为主动句，中国汉语的习惯①译成无主语的主动句Measures have been taken to diminish air pollution.已经采取了一些措施来减少空气污染。

►If the product is a new compound，the structure must be proved independently．►Quality must be guaranteed first.②加上不确定主语的主动句Salt is known to have a very strong corroding effect on metals.大家知道，盐对金属有很强的腐蚀作用。

►All bodies are known to possess weight.►If one or more electrons are removed, the atom is said to be positively charged．③由by短语中的动作发出者作为主语Heat and light are given off by the chemical reaction.这种化学反应能发出热和光。

►The planets are held together by attractive forces.►Every day, new compounds are produced in the laboratory by the synthetic organic chemist. （3）译成判断句Currently most solar cells are made from crystals of high-purity silicon.目前，绝大多数太阳能电池是用高纯度的硅晶体制成的。

►Large quantities of oil are refined locally at Abadan, Iran, in Bahrain and elsewhere.Produced by electrons are the x-ray, which allow the doctor to took aside a patient’s body. （4）译成因果句The crops were badly damaged by a flood. 农作物因水灾而毁坏。

The multiplicity of carbon compounds is explained in the exceptional ability of carbon atoms to combine with one another.碳化合物之所以为数众多，是因为碳原子相互结合的能力特别强。

►The existence of organic chemistry is further justified by the importance of carbon compounds or mixtures in our lives.2. 从句科技英语大量使用复合句是其重要的特征之一，一个复合句可能由主句和多个主句组成。

理解和掌握各种从句的译法对理解和翻译科技英语是非常重要的。

1）主语从句①基本句型：连词（连接代词、连接副词）+主语+谓语+谓语Why dinaucers became extinct remained a mystery for a long time.恐龙为什么绝迹长期以来是个谜。

►Whether there is life on the Mars is a disputable topic.②用what引起的主语从句What we call weight is really the gravitational pull on an object.我们所称之重量实际上是对某一物体的地心引力。

►What cannot be seen with the eye can be easily found with a radar instrument.③用it做主语的复合句►It is important that the metal for making aeroplanes should resist corrosion.☺It is said that all matters is made up of atoms.2）宾语从句①带有宾语从句的复合句：一般按原句顺序翻译A product must be carefully tested to determine if it will perform its job properly and reliably.产品必须自己检查，以确定是否合格可靠。

►Newton believed that gravitation is everywhere——that is, it is universal.②用what引起的宾语从句常有“the thing which”的含义，译为“所……的东西（或事物）”：The computer can only do what they are told to do.计算机只能做人们所要它做的事情。

►When the atoms of different elements combine or react chemically, they form what are called “molecules”.③介词所带的宾语从句除动词外，介词也可带有宾语从句，这时从句不能用that引导，而是连接代词或连接副词引导，翻译时要把宾语从句处理成一个短语。

Energy is rather difficult to define, but most of us have a concept of what it is.给能量下定义是相当不容易的，但我们大多数人对这一概念都有所了解。

►The value of a machine depends on how much work it can do per hour, or per second.④符合宾语中的宾语从句►Time and again Newton made it clear that motion is relative.☺Ancient people believed it to be true that the sun turned around the earth.3）表语从句①表语从句一般译法►One of the most important facts about light is that it travels in straight line.☺Why don’t we fall off the earth? The answer is that gravity keeps us from falling off.②由what引起的表语从句Oil coming from the ground is what we call crude oil.从地下喷出的石油就是我们所说的原油。

►Carbon is what makes up a major ingredient in coal, wood, gasoline, oil, or any other fuel. 4）同位语从句①把同位语从句译在其先行词之前，二者之间用“这一”或“的”连接。

The question whether there is life on Mars is still disputable.火星是否有生命这一问题仍在争论之中。

►The distilling unit separates oil into different products by taking advantage of the fact that the hydrocarbons boils at different temperatures.②按照原文顺序翻译，在先行词前加“这一”等次，其后加冒号或破折号，然后译出同位语从句，这种方法只能用在同位语从句及其先行词不在句首的复合句中。
