EXPERIMENT 1: DENSITY OF SOLIDS

The density of a substance is defined as its mass per unit volume. The most obvious way to determine the density of a solid is to weigh a sample of the solid and then find out the volume that the sample occupies. In this experiment, you will be supplied with variously shaped pieces of metal. You are asked to determine the density of each specimen and then, by comparison with a table of known densities, to identify the metal in each specimen. As shown in Table 1, density is a characteristic property.

Table 1: Densities of Some Common Metals, g/cc

Aluminum 2.7

Lead 11.4

Magnesium 1.8

Monel metal alloy 8.9

Steel ( Fe, 1% C) 7.8

Tin 7.3

Wood’s metal alloy 9.7

Zinc 7.1

PROCEDURE

Procedure (obtain) an unknown specimen from your instructor. Weigh the sample accurately on an analytical balance.

Determine the volume of your specimen by measuring the appropriate dimensions. For example, for a cylindrical sample, measure the diameter and length of the cylinder. Calculate the volume of the sample.

Determine the volume of your specimen directly by carefully sliding the specimen into a graduated cylinder containing a known volume of water. Make sure that no air bubbles are trapped. Note the total volume of the water and specimen.

Repeat with another unknown as directed by your instructor.

第二篇：科技翻译技巧

如前所述，本章将介绍科技英语翻译中常用的五种技巧：转译法、省译法、增译法、还原法及倒置法。

转泽法主要有词类转译和句子成分转译两种。

一、词类的转译

如前所述，英语的一个词类能充当的句子成分较少，充当不同成分时常需改变词类；而汉语的一个词类能充当的句子较多，充当不同句子成分时无需改变词类。因此英汉翻译时，原语中的某种词类不一定还要，也往往不可能译成汉语中的同一词类，而应根据译语的习惯和需要，转译成另一种词类。这就是所谓词类的转译。

（一）英语名词的转译

1．转译为汉语的动词

(1)具有动作意义的名词(也称“行为名词”，英语叫做Action Nouns)的转译

英语中有一些具有动作意义的名词，这些名词汉译时往往要转译为汉语的动词，才会使译文通顺，合符汉语的习惯。如：

1． Television is the transmission and reception, of images moving objects by radio waves. 电视通过无线电发送和接收活动物体的图像。

2. Integrated circuits are fairly recent development.

集成电路只是近年才发展起来的。

3. The transfer of information from one part of the computer to another depends on the electric current being conducted over wires.

信息从计算机的一部分传送到另一个部分，靠的是电线中传导的电流。

4. The transformation could be from any convenient input voltage to any convenient output voltage.

可将任一所需转换的输入电压整换成任一所希望的输出电压。

5. The operation of an electric machine needs some knowledge of its performance. 操作电机需要懂得电机的一些性能。

6. Discussions of the application of the second method of Liapunov to the stability analysis of linear time—invariant systems are given later.

随后，讨论李亚普诺夫第二方法在线性时不变系统稳定性分析中的应用。

7. The tests indicate that a countercurrent flow of gases and solids is necessary in the reactor. 诚验表明，使气体和固体在反应器内逆向流动是必要的。

8. Laser has the applicability to many fields of science and the adaptability to practical uses. 激光可应用于许多科学领域，也适合各种实际用途。

9. A one-celled animal or plant cannot, of course, survive the destruction, of its one cell.

单细胞的动物或植物，在仅有的一个细胞被破坏后当然就不能生存。

The air is made up of mixture of gases．

空气是由若干种气体混合而成的。

与具有动作意义的名词转译成动词相类似的，便是动名词的转译。动名词实际上就是一个具有动作意义的名词。因汉语中根本就没有动名词，因此这类词可与“具有动作意义的名词”一样处理，即在汉译时转译成动词。如：

Reversing the direction of the current reverses the direction of its lines of force.

倒转电流的方向也就倒转了它的磁力线方向。

No other changes occur upon mixing the two compounds,

把这两种物质混合起来没有发生其他变化。

This kind of the pipes can be used for carrying air, gas, water, etc．

这种管予可用来输送空气、煤气和水等。

(2)某些由动词作词根+er（或or）构成的名词，当它并不是真正表示个人的职业，而具有较强的动作意义时，可将其转译成汉语的动词。如：

Professor Wang was the instructor of our experiment.

王教授指导我们做实验。

He was a good calculator, so we considered the answer correct.

他算得很好，因此，我们认为这个答案是正确的。

He was our good supporter.

他很支持我们的方案。

(3)某些中心词(Head Word)是名词的习语化动词词组，其中心词可转译为动词。如： Anyone who has a look at an old radio set will remember the large, heavy vacuum tube and other components.

凡是看过老式收音机的人，一定会记得那些硕大而笨重的真空管和其他元件。 He had a good knowledge of chemistry.

他精通化学。

类似的动词词组还有make use of，have a try，take care of等等。

(4)某些中心词是名词的介词短语，其中心词可转译为动词。如：

A body is negatively charged when it has electrons in excess of its normal number. 当物体所带电子超过正常数时，该物体便带负电。

Most experiments at very low temperature are made with the help of liquid helium． 大多数低温试验都要借助于液态氦。

With the use of the increased temperature and pressure, the oil is cracked into lighter or heavier fractions.

利用升温升压，可将石油裂化成轻馏分或重馏分。

2．转译为汉语的形容词

在英语中，有些表达事物性质的名词是由形容词派生而来的，其本身就具有形容词的性质。汉译这类词时，可转译为汉语的形容词。如：

Single crystals of high perfection are an absolute necessity for the fabrication of integrated circuits.

对制造集成电路来说，高纯度的单晶是绝对必要的。

The lower stretches of rivers show considerable variety.

河流下游的情况是大不相同的。

（二）英语形容词的转泽

1．转译为汉语的动词

当形容词作表语、主语、补足语或其他成分时，可转译为汉语的动词。如：

（三）英语动词的转译

1．英语动词的分类

英语动词分为两类：

(1)状态动词(State Verb) 状态动词不表真正的动作，只表某种状态。 (2)行为动词(Action Verb) 英语中只有行为动词才表真正的动作。

2．动词的转译

无论是状态动词还是行为动词，在一定情况下均可转译为汉语的名词。如： The instrument is characterized by its compactness and portability.

副词转译为形容词还有不少其他情况，如： Today gold is mined from quartz rocks deep below the earth's surface． 现在的黄金是从深埋在地下的石英岩里开采出来的。 原句中．today这个副词并不是修饰gold，而是作整个句子的状语，此处我们将其转译成修饰gold的定语。又如：

Concrete structures generally do not require much maintenance, internally or externally，if adequate provision is made for good expansion joints and firm foundations.

如果有良好的伸缩缝和坚实的基础，混凝土结构一般不需要大量的室内外维修。

2．转译为汉语的名词

某些由名词派生的副词，可转译为汉语的名词。如：

3．转译成汉语的动词

(1)英语中的某些副词，如：on，off，up，m，out，over，behind，forward，away?，在与系动词be构成合成谓语，或作宾语补足语，或作状语，可转译为汉语的动词。如： Today chemical experiment is over.

不久他就产生了用电动机代替蒸汽机的想法。

（五）英语中介词的转译

英语中有不少介词，如：about，、of，for．by，in，past，with，over, into, around, across, toward, through, throughout等，都具有较强的动词意味，汉译时也可转译成汉语的动词。如： The chlorine from salt is used for bleaching paper and textiles.

Cell receptor research is in its infancy.

细胞受体的研究仍处于初级阶段。

二、句子成分的转译

前面我们讲了在英汉翻译中各种词类的转译问题。由于各类词都具有自身的语法功能，它们在造句时各行其职。因此，在进行词类转译时，其语法功能往往也就随之而改变了。因此，其充当句子中的成分也就随之而改变了。例如，，动词转译为名词后，谓语就可能变为主语；名词转译为形容词后，主语就可能变成了定语；副词转译为名词后，状语就可能成了主语，等等。所以，可以这样说，在前面所讲的词类转换中，不少总是伴随着句子成分的转译。因此，与此相关的句子成分的转译，在此没有讨论的必要。

但在某些场合，词类的转换并不引起句子成分的改变。例如，作主语的动名词短语改译为动宾短语时，仍可作主语；用作表语的形容词改译为动词后。在汉语中仍起谓语的作用，等等。可见，词类转译与句子成分的转译之间有其联系，但并不是一回事。前者是从词类的角度进行的转译，后者纯粹是从句子中语法地位的角度进行的转译。

此处，我们所说的句子成分的转译，是句子成分直接意义上的转译。也就是说，在汉译时，要使句子通顺、言语流畅，且符合汉语的规范和习惯，有时光靠词类转换还难以做到。

这时，若将句中的某些语法成分加以转换翻译（此时其词类并不一定改变，只是其语法功能改变），则可达到很好的效果。

句子成分转译的情况有多种多样，方式可谓异彩纷呈。可以这样说，几乎所有的句子成分都可以转译。

（一）主语的转译

1．转译为汉语的宾语

(1)如前所述，在英语特别是科技英语中，被动语态使用较为广泛，而汉语则运用得较少。因此，汉译时多改译为主动语态。这

时，英语句中的主语便转译为汉语的宾语了。如：

目前全国上下正在大力开展科学研究。

2．转译为汉语的谓语

当主语是动作性名词，如：care，need，attention，thought，improvement，overview，attempt，emphasis等等，而谓语动词为系动词或被动形式时，主语便可转译为汉语的谓语。

(1)当译文较短时，可译为警示性无主句。如：

Care should be taken to protect the instrument from dust and dump.

应当注意保护仪器，避免灰尘和潮湿。

Attention is necessary to prevent the electronic instrument from damaging.

必须注意，以防电子仪器损坏。

(2)当译文较长时，可视情况添加适当的主语。如：

显然，半导体的导电性比金属差。

试比较：显然．半导体具有比金属更差的导电性能。

（四）表语的转译

1．转译成汉语的主语

(1) 若表语与主语指的是同一事物（或人），或表语所指的事物（或人）在意思上等同于主语．汉译时其位置可以颠倒，即将表语转译为主语。如：

One of the first men to work with such reactions was the great English scientist Michael Faraday.

伟大的英科学家法拉第是最早研究这种反应的人之一。

橡胶的介电性比空气好，但绝缘性比空气差。

One of the most active metal is Sodium.

钠是最活泼的金属之一。

(2)当表语表示主语的某种属性时，有时也可转译为主语。

这时，形容词转换成了名词。如：

This information is essential to the laboratory technologist in two respects. 本资料对于实验室技术人员的重要性有两点。 This metal is less hard than that one. 这种金属的硬度比那种差。 2．转译成汉语的谓语

(1)当英语中作表语的是动作性很强的一类名词时，可将该表语转译为谓语。如：

Electronics is the study of the flow of electrons and the application of such knowledge to practical problems in communications and controls.

电子学研究电子运动规律，并把这种知识运用于通信和控制的实际问题。

如果我们不知道原子的结构，就不能研究核子物理学。

Sugar and salt are both soluble in water. 糖和盐都溶于水。 He was responsible for many scientific advances. 他对科学做出过许多贡献。

3．转译成汉语的定语

在系表结构中，如主语带有定语，有时可将表语转译为主语的定语，且往往原来的定语转译为表语。如：

In carrying out these tests several features were desirable in the design of rig if consistent results are to be obtained.

进行这些试验时，如果获得的结果始终一致，则说明设计的试验方案的一些性能符合要求。
