第三章单
词
• 单词是构成句子的基本要素之一，因此，单词的翻译直接关系到句子3.1.1 可数名词复数前没有数量词时，一般要把复数含义翻译出来，即在名词前加译“一些，这些，许多”等词，例如： • The teacher may be asked questions. 可以向老师提一些问题。 • Our first electronic computers were made in 1958. 我国首批电子计算机是1958年制成的。 • we are students of Henan University. 我们是河南大学的学生。
3.1.3 a(an)+名词（可数，不可数）单数表示“一类” 时，不能译出不定冠词“a(an)”
Salts may also be found by the replacement of hydrogen from an acid with a metal. 盐也能通过用金属置换酸中的氢而获得。
An acid was once defined as a substance that would form hydrogen ions(H+) in water solution and a base as one that would form hydroxide ions(OH-) in the same. 人们曾把酸定义为在水溶液中能产生氢离子的物质，而碱则是在同样溶液中会产生氢氧根离子的物质。
• 注：对于billion及其以上的数字，英语和美语的译法不同，翻译时应视此句出于何种国家的刊物而定。英语美语 million 106 106 billion 1012（万亿） 109（十亿） trillion 1018（百万兆） 1012（兆,百万个百万） quadrillion 1024（百万的四次方）1015（一千的五次方） quintillion 1030（百万的五次方） 1018（百万之三次方）

化学化工专业英语（课本内容）

化学化工专业英语（课本内容）第二章科技英语构词法词是构成句子的要素，对词意理解的好坏直接关系到翻译的质量。

所谓构词法即词的构成方法，即词在结构上的规律。

科技英语构词特点是外来语多（很多来自希腊语和拉丁语）；第二个特点是构词方法多，除了非科技英语中常用的三种构词法—转化、派生及合成法外，还普遍采用压缩法、混成法、符号法和字母象形法。

2.1转化法（Conversion）由一种词类转化成另一种词类，叫转化法。

例如：water(n.水)→water(v.浇水)charge(n.电荷) →charge(v.充电)yield(n.产率) →yield(v.生成)dry(a.干的) →dry（v.烘干）slow(a.慢的) →slow(v.减慢)back(ad.在后、向后) →back（v.使后退、倒车）square(n.正方形) →square(a.正方形的)2.2派生法（Derivation）通过加前、后缀构成一新词。

派生法是化工类科技英语中最常用的构词法。

例如“烷烃”就是用前缀（如拉丁或希腊前缀）表示分子中碳原子数再加上“-ane”作词尾构成的。

若将词尾变成“-ane”、“-yne”、“-ol”、“-al”、“-yl”，则分别表示“烯”、“炔”、“醇”、“醛”、“基”、等。

依此类推，从而构成千成种化学物质名词。

常遇到这样的情况，许多化学化工名词在字典上查不到，全若掌握这种构词法，能过其前、后缀分别代表的意思，合在一起即是该词的意义。

下面通过表1举例说明。

需要注意的是，表中物质的数目词头除前四个另有名称外，其它均为表上的数目词头。

本书附录为化学化工专业常用词根及前后缀。

此外还可参阅《英汉化学化工词汇》（第三版）附录中的“英汉对照有机基名表”、“西文化学名词中常用的数止词头”及“英汉对照有机词尾表”。

据估计，知道一个前缀可帮助人们认识450个英语单词。

一名科技工作者至少要知道近50个前缀和30个后缀。

这对扩大科技词汇量，增强自由阅读能力，提高翻译质量和加快翻译速度都是大有裨益的。

Transportation, housing, clothing, communication, recreation, and food production —virtually every segment of our everyday lives is influenced to one degree or another by materials. Historically, the development and advancement of societies have been intimately tied to the members’ ability to produce and manipulate materi- als to fill their needs. In fact, early civilizations have been designated by the level of their materials development (Stone Age, Bronze Age, Iron Age).The earliest humans had access to only a very limited number of materials, those that occur naturally: stone, wood, clay, skins, and so on. With time they discovered techniques for producing materials that had properties superior to those of the natural ones; these new materials included pottery and various metals. Furthermore, it was discovered that the properties of a material could be altered by heat treatments and by the addition of other substances. At this point, materials utilization was totally a selection process that involved deciding from a given, rather limited set of materials the one best suited for an application by virtue of its characteristics.①It was not until relatively recent times that scientists came to understand the relationships between the structural elements of materials and their properties. This knowledge, acquired over approximately the past 100 years, has empowered them to fashion, to a large degree, the characteristics of materials. Thus, tens of thousands of different materials have evolved with rather specialized charac- teristics that meet the needs of our modern and complex society; these include metals, plastics, glasses, and fibers. deep-seated根深蒂固的, 深层的pottery / ☐♦☯❒♓/ ⏹ 陶器structural elements结构成分；property / ☐❒☐☜♦♓/⏹.性能The development of many technologies that make our existence so comfortable has been intimately associated with the accessibility of suitable materials. An advancement in the understanding of a material type is often the forerunner to the stepwise progression of a technology. For example, automobiles would not havebeen possibl- e without the availability of inexpensive steel or some other comparable substitute. In our contemporary era, sophisticated electronic devices rely on components that are made from what are called semiconducting materials. Materials Science and EngineeringThe discipline of materials science involves investigating the relationships that exist between the structures and properties of materials. In contrast, materials engineering is, on the basis of these structure–property correlations, designing or engineering the structure of a material to produce a predetermined set of properties.“Structure’’ is at this point a nebulous term that deserves some explanation. In brief, the structure of a material usually relates to the arrangement of its internal components. Subatomic structure involves electrons within the individual atoms and interactions with their nuclei. On an atomic level, structure encompasses the organization of atoms or molecules relative to one another. The next larger structural realm, which contains large groups of atoms that are normally agglomerated together, is termed ‘‘microscopic,’’ meaning that which is subject to direct observation using some type of microscope. Finally, structural elements that may be vie wed with the naked eye are termed ‘‘macroscopic.’’The notion of ‘‘property’’ deserves elaboration. While in service use, all materials are exposed to external stimuli that evoke some type of response. For example, a specimen subjected to forces will experience deformation; or a polished metal surface will reflect light. Property is a material trait in terms of the kind and magnitude of response to a specific imposed stimulus. Generally, definitions of properties are made independent of material shape and size.Virtually all important properties of solid materials may be grouped into six different categories: mechanical, electrical, thermal, magnetic, optical, and stepwise / ♦♦♏☐♦♋♓/ ♎逐步的sophisticated/♦☯♐♓♦♦♓ ♏♓♦♓♎/ ♎精制的，复杂的；semiconducting materials 半导体材料nebulous/ ⏹♏♌✞●☯♦/♎ 含糊的，有歧义的subatomic/ ♦✈♌☯♦❍/♎ 亚原子的microscopic/❍♓❒☯♦☐♓/ ♎微观的❍♋♍❒☐♦♍☐☐♓♍/❍✌ ❒☯✞♦☐♓/♎宏观的deteriorative. For each there is a characteristic type of stimulus capable of provokingdifferent responses. Mechanical properties relate deformation to an applied load or force; examples include elastic modulus and strength. For electrical properties, such as electrical conductivity and dielectric constant, the stimulus is an electric field. The thermal behavior of solids can be represented in terms of heat capacity and thermal conductivity. Magnetic properties demonstrate the response of a material to the application of a magnetic field. For optical properties, the stimulus is electro- magnetic or light radiation; index of refraction and reflectivity are representative optical properties. Finally, deteriorative characteristics indicate the chemical reactivity of materials.In addition to structure and properties, two other important components are involved in the science and engineering of materials, viz. ‘‘processing’’ and ‘‘performance.’’ With regard to the relationships of these four components, the structure of a material will depend on how it is processed. Furthermore, a material’s performance will be a function of its properties.Fig. 1.1 Photograph showing the light transmittance of three aluminum oxide specimens. From left to right: single crystal material (sapphire), which is transparent;a polycrystalline and fully dense (nonporous) material, which is translucent; and a polycrystalline material that contains approximately 5% porosity, which is opaque. (Specimen preparation, P. A. Lessing; photography by J. Telford.)We now present an example of these processing-structure-properties-perfor- mance principles with Figure 1.1, a photograph showing three thin disk specimens placed over some printed matter. It is obvious that the optical properties (i.e., the deformation/ ♎♓♐ ❍♏♓☞☯⏹/ ⏹变形deteriorative/♎♓♦♓☯❒♓☯❒♏♓♦♓❖/ ⏹破坏（老化的）elastic modulus 弹性模量strength /♦♦❒♏⏹♑/ ⏹强度；dielectric constant介电常数；heat capacity 热容量refraction/❒♓♐❒✌☞☯⏹/ ⏹折射率；reflectivity/ ❒♓♐●♏ ♦♓❖♓♦♓/ ⏹反射率processing/☐❒☯◆♦♏♦♓☠/ ⏹加工light transmittance) of each of the three materials are different; the one on the left is transparent (i.e., virtually all of the reflected light passes through it), whereas the disks in the center and on the right are, respectively, translucent and opaque.All of these specimens are of the same material, aluminum oxide, but the leftmost one is what we call a single crystal—that is, it is highly perfect—which gives rise to its transparency. The center one is composed of numerous and verysmall single crystals that are all connected; the boundaries between these small crystals scatter a portion of the light reflected from the printed page, which makes this material optically translucent.②And finally, the specimen on the right is composed not only of many small, interconnected crystals, but also of a large number of very small pores or void spaces. These pores also effectively scatter the reflected light and render this material opaque.Thus, the structures of these three specimens are different in terms of crystal boundaries and pores, which affect the optical transmittance properties. Furthermore, each material was produced using a different processing technique. And, of course, if optical transmittance is an important parameter relative to the ultimate in-service application, the performance of each material will be different.Why Study Materials science and Engineering?Why do we study materials? Many an applied scientist or engineer, whether mechanical, civil, chemical, or electrical, will at one time or another be exposed to a design problem involving materials. Examples might include a transmission gear, the superstructure for a building, an oil refinery component, or an integrated circuit chip. Of course, materials scientists and engineers are specialists who are totally involved in the investigation and design of materials.Many times, a materials problem is one of selecting the right material from the many thousands that are available. There are several criteria on which the final decision is normally based. First of all, the in-service conditions must be charac- terized, for these will dictate the properties required of the material. On only rare occasions does a material possess the maximum or ideal combination of properties. transmittance/♦❒✌⏹❍♓♦☜⏹♦/ ⏹. 透射性sapphire /♦✌♐♓☯/ ⏹蓝宝石transparent/♦❒✌⏹♦☐☪☯❒☯⏹♦/ ♎透明的；polycrystalline/ ☐●♓❒♓♦♦☯●♓⏹/ ⏹多晶体；translucent/♦❒✌⏹●✞♦⏹♦/♎ 半透明的；opaque☯✞☐♏♓♎不透明的single crystal 单晶体Thus, it may be necessary to trade off one characteristic for another. The classic example involves strength and ductility; normally, a material having a high strength will have only a limited ductility. In such cases a reasonable compromise between two or more properties may be necessary.A second selection consideration is any deterioration of material properties that may occur during service operation. For example, significant reductions in mecha- nical strength may result from exposure to elevated temperatures or corrosive envir- onments.Finally, probably the overriding consideration is that of economics: What will the finished product cost? A material may be found that has the ideal set of proper- ties but is prohibitively expensive. Here again, some compromise is inevitable.The cost of a finished piece also includes any expense incurred during fabrication to produce the desired shape. The more familiar an engineer or scientist is with the various characteristics and structure–property relationships, as well as processing techniques of materials, the more proficient and confident he or she will be to make judicious materials choices based on these criteria.③Reference:William D.

Here is an important list of rules to follow:
1. The parent chain is numbered so that the multiple bonds have the lowest numbers (double and triple bonds have priority over alkyl and halo substituents).
3. When both double and triple bonds are present, the -en suffix follows the parent chain directly and the -yne suffix follows the -en suffix (notice that the e is left off, -en instead of -ene). The location of the double bond(s) is(are) indicated before the parent name as before, and the location of the triple bond(s) is(are) indicated between the -en and -yne suffixes. See below for examples.

Unit 3 Typical Activities of Chemical Engineers化学工程师的例行工作The classical role of the chemical engineer is to take the discoveries made by the chemist in the laboratory and develop them into money--making, commercial-scale chemical processes. The chemist works in test tubes and Parr bombs with very small quantities of reactants and products (e.g., 100 ml), usually running “batch”, constant-temperature experiments. Reactants are placed in a small container in a constant temperature bath. A catalyst is added and the reactions proceed with time. Samples are taken at appropriate intervals to follow the consumption of the reactants and the production of products as time progresses.化学工程师经典的角色是把化学家在实验室里的发现拿来并发展成为能赚钱的、商业规模的化学过程。

化学家用少量的反应物在试管和派式氧弹中反应相应得到少量的生成物，所进行的通常是间歇性的恒温下的实验，反应物放在很小的置于恒温水槽的容器中，加点催化剂，反应继续进行，随时间推移，反应物被消耗，并有生成物产生，产物在合适的间歇时间获得。

因为化合物含有两种或更多的元素, 因而其与元素的性质不同, 他们可以通过化学变化分解成更简单的物质。

化合物经化学分解最终产生的物质正是组成化合物的元素。

组成化合物的元素的原子以整数比例，而非以分数比，结合在一起。

(组成化合物的元素各原子间以整数比例而非分数比结合在一起)原子间相互结合形成的化合物以分子或离子状态存在。

一个化合物的分子是由两个或两个以上的原子组成的，化合物的分子体积很小，而且不带电(呈电中性).如果我们把一滴水细分成越来越小的微粒, 我们最终可以得到一个水的单体，即一个水分子。

这个水分子是由两个氢原子和一个氧原子键合在一起。

人们通常无法进一步分解分子单元, 只有破坏分子结构才能将其分解成所组成的元素。

因此, 水分子是水这种化合物的最小单元。

离子是带正电的或负电的原子或元素簇。

一个化合物中的离子依靠它们正电和负电基团间的相互引力结合在一起, 形成晶体结构。

由离子组成的化合物中不存在分子。

氯化钠是一种典型的非分子结构的化合物。

这类化合物包含大量的正、负离子, 其分子式如分子结构的化合物那样，通常采用组成化合物的原子间以简单比例式方式来表达。

大致说来，理解阶段包括一下几个方面：
1.领略全文大意
通读一遍，不同的词，词组甚至是句子在不同的语境中可能有不同的意思。任何一篇文章或一段文字都是一个有机整体，词与词，词与句子，句子与段落甚至整个篇章之间，都有着必然的内在联系。这就要求译者在动手翻译之前，务必通读全文，领略大意，切忌一开始就把注意力集中在一词一词的推敲上，看一句译一句。
第一注意表达的规范性
科技英语语体讲究论证的逻辑性，语言要规范。我们翻译的是科技文章，自然就必须用符合科技语体规范的汉语来表达。例如：
The rotation of the earth on its own axis causes the change from day to night. 地球绕轴自转，造成昼夜的更替。
3.广泛使用缩写词，并且缩写词的词义专一，使用频率高。
4.前后缀出现频率高
英语的构词法主要有：合成、转化和派生，其中派生法的核心是依靠添加前缀或后缀来构成新词，这就导致了前后缀使用频率高。
例如：
bio-
biochemistry; biotechnology; biocatalyst; biodegradable能生物降解的; bioengineering, etc.
表达的好坏取决于理解原文的确切程度和对汉语的掌握程度。如果译文仅仅是意思对，但不能用通顺流畅的汉语表达，仍不是一篇好译文。
例句：
The homologs of benzene are those containing an alkyl group or alkyl groups in place of one or more hydrogen atoms．
该句话易于理解，但却难于表达。若译作：苯的同系物就是那些被一个或多个烷基取代一个或多个氢原子所形成的产物。则该译文尽管意思差不多，但令人感到啰唆费解。
