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。

Unit 1 Chemical Industry化学工业1.化学工业的起源尽管化学品的使用可以追溯到古代文明时代,我们所谓的现代化学工业的发展却是非常近代(才开始的)。
可以认为它起源于工业革命其间,大约在1800年,并发展成为为其它工业部门提供化学原料的产业。
比如制肥皂所用的碱,棉布生产所用的漂白粉,玻璃制造业所用的硅及Na2CO3. 我们会注意到所有这些都是无机物。
有机化学工业的开始是在十九世纪六十年代以William Henry Perkin 发现第一种合成染料—苯胺紫并加以开发利用为标志的。
20世纪初,德国花费大量资金用于实用化学方面的重点研究,到1914年,德国的化学工业在世界化学产品市场上占有75%的份额。
这要归因于新染料的发现以及硫酸的接触法生产和氨的哈伯生产工艺的发展。
而后者需要较大的技术突破使得化学反应第一次可以在非常高的压力条件下进行。
这方面所取得的成绩对德国很有帮助。
特别是由于1914年第一次世界大仗的爆发,对以氮为基础的化合物的需求飞速增长。
这种深刻的改变一直持续到战后(1918-1939)。
1940年以来,化学工业一直以引人注目的速度飞速发展。
尽管这种发展的速度近年来已大大减慢。
化学工业的发展由于1950年以来石油化学领域的研究和开发大部分在有机化学方面取得。
石油化工在60年代和70年代的迅猛发展主要是由于人们对于合成高聚物如聚乙烯、聚丙烯、尼龙、聚脂和环氧树脂的需求巨大增加。
今天的化学工业已经是制造业中有着许多分支的部门,并且在制造业中起着核心的作用。
它生产了数千种不同的化学产品,而人们通常只接触到终端产品或消费品。
这些产品被购买是因为他们具有某些性质适合(人们)的一些特别的用途,例如,用于盆的不粘涂层或一种杀虫剂。
这些化学产品归根到底是由于它们能产生的作用而被购买的。
2.化学工业的定义在本世纪初,要定义什么是化学工业是不太困难的,因为那时所生产的化学品是很有限的,而且是非常清楚的化学品,例如,烧碱,硫酸。

Lesson2 Chemical Equilibrium and Kinetics化学平衡和动力学A1 A major objective of chemist is to understand chemical reactions, to know whether under a given set of conditions two substances will react when mixed, to determine whether a given reaction will be exothermic or endothermic, and to predict the extent to which a given reaction will proceed before equilibrium is established.化学家的一个主要目标是理解化学反应,知道在一组给定的条件下两种物质混合时能否发生反应;确定一个给定的反应是放热还是吸热;预测一个给定的反应在平衡前进行的程度。
2 An equilibrium state, produced as a consequence of two opposing reactions occurring simultaneously, is a state in which there is no net change as long as there is no change in conditions.平衡状态是由两个对立反应同时发生产生的结果,在平衡状态下,只要条件不发生改变,这个状态就不会有净变化。
3 In this lesson it will be shown how one predict the equilibrium state of chemical systems from thermodynamic data, and conversely how the experimental measurements on equilibrium states provide useful thermodynamic data.在这节课中,将会展示如何根据热力学数据来预测化学体系的平衡状态,以及相反地,平衡状态下的实验测量值如何提供有用的热力学数据。

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 deep-seated根深蒂固的, 深层的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 propertiessuperior 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.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, pottery // 陶器structural elements结构成分;property //.性能automobiles would not have been 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 viewed 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. 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//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 deteriorative. For each there is a characteristic type of stimulus capable of provoking different 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. 微观的// 宏观的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。

Unit 2 Research and Development研究和开发Research and development, or R&D as it is commonly referred to, is an activity which is carried out by all sectors of manufacturing industry but its extent varies considerably, as we will see shortly. Let us first understand, or at least get a feel for, what the terms mean. Although the distinction between research and development is not always clear-cut, and there is often considerable overlap, we will attempt to separate them. In simple terms research can be thought of as the activity which produces new ideas and knowledge whereas development is putting those ideas into practice as new process and products. To illustrate this with an example, predicting the structure of a new molecule which would have a specific biological activity and synthesizing it could be seen as research whereas testing it and developing it to the point where it could be marketed as a new drug could be described as the development part.研究和开发,或通常所称R&D是制造业各个部门都要进行的一项活动。

These are used by industries that need the liquid sodium, mainly in the production of tetra-alkyl lead petroleum additives, though the petroleum additive companies are diversifying and other uses may appear.
The industry will move more to serving the rest of the chemical industry and less to serving the farming industry.
工业将趋向于效劳化学工业的其余局部,而不是农业。
Another threat is the perceived environmental messiness of many large-scale
Extent of branching: 支链长度 Crossing-linking: 交联
Random copolymer: 无规共聚物 Alternating copolymer:交替共聚物 Block copolymer: 嵌段共聚物

The Anatomy of a Chemical Manufacturing Process 化工生产过程构成The basic components of a typical chemical process(n过程;步骤;方法;工艺,vt 加工;处理) are shown in Fig.1, in which each block represents a stage in the overall process for producing a product from the raw materials. Fig.1 represents a generalized(无显著特点的,一般的) process; not all the stages(步骤;阶段) will be needed for any particular(特定的) process and the complexity of each stage will depend on the nature of the process. Chemical engineering design is concerned with the selection and arrangement(排列;安排)of the stages, and the selection, specification and design of the equipment required to perform(演出;执行;完成任务) the stage functions.典型的化学工艺的基本构成示于图1., 在此图中,每一个方框表示从原料到加工成产品的全过程中的一个步骤。
图1所示只是一般的情况,对于一个特定的工艺来说并非所有的步骤都是必需的,而且每一个步骤的复杂程度取决于生产过程的性质。
化工设计所关注的是各步骤的选择与安排,以及完成各步骤的任务所需设备的选择、说明和设计。

At the very least: 一点, 丝毫(加强语气) Boom and bust: ห้องสมุดไป่ตู้时性繁荣; 经济繁荣与萧条的交替循环
参考译文 基础化学品是化学工业的弃儿。 他们不像药品那样引人注目 , 而且时常无利可图
(在经济繁荣与萧条的不可预测的交替循环中, 利润很少) 。 它们不被公众直接应用, 因此其 重要性通常不被理解。 即使在(化学) 工业内部, 它们的重要性通常也得不到充分的理解。 然 而, 如果没有它们, 其它工业则无法存在。
参考译文:基础化学工业的工作就是找到把原材料转化成有用中间体 的经济方法。对任何公司来说为他们的产品升值都很少有回旋的余地。 因此, 以最低成本生产的公司才可能取得最大的利润。 这种情况意 味着公司必须时刻注意寻找新的和更为经济的方法去制造和转化原材 料。
Many basic chemicals are the products of oil refining, while parts of the industry--the sulphur, nitrogen, phosphorus and chloro-alkali industries--put elements other than carbon and hydrogen into chemicals. In combination, these products and the basic products of the petrochemical industry can be combined to produce the myriad (无数的)of important chemicals that feed the rest of the chemical industry.

1 CHEMISTRY AND CHEMISTWithout chemistry our lives would beunrecognisable, for chemistry is at work all aroundus. Think what life would be like without chemistry- there would be no plastics, no electricity and noprotective paints for our homes. There would be no synthetic fibres to clothe us and no fertilisers to help us produce enough food. We wouldn‟t be able to travel because there would be no metal, rubber or fuel for cars, ships and aeroplane. Our lives would be changed considerably without telephones, radio, television or computers, all of which depend on chemistry for the manufacture of their parts. Life expectancy would be much lower, too, as there would be no drugs to fight disease.Chemistry is at the forefront of scientific adventure, and you could make your own contribution to the rapidly expanding technology we are enjoying. Take some of the recent academic research: computer graphics allow us to predict whether small molecules will fit into or react with larger ones - this could lead to a whole new generation of drugs to control disease; chemists are also studying the use of chemicals to trap the sun‟s energy and to purify sea water; they are also investigating the possibility of using new ceramic materials to replace metals which can corrode.Biotechnology is helping us to develop new sources of food and new ways of producing fuel, as well as producing new remedies for the sick. As the computer helps us to predict and interpret results from the test tube, the speed, accuracy and quality of results is rapidly increasing - all to the benefit of product development.It is the job of chemists to provide us with new materials to take us into the next century, and by pursuing the subject, you could make your positive contribution to society.Here are some good reasons for choosing chemistry as a career.Firstly, if you have an interest in the chemical sciences, you can probably imagine taking some responsibility for the development of new technology. New ideas and materials are constantly being used in technology to improve the society in which we live. You could work in a field where research and innovation are of primary importance to standards of living, so you could see the practical results of your work in every day use.Secondly, chemistry offers many career opportunities, whether working in a public service such as a water treatment plant, or high level research and development in industry. Your chemistry-based skills and experience can be used, not only in many different areas within the chemical industry, but also as the basis for a more general career in business.1 As a qualification, chemistry is highly regarded as a sound basis for employment.You should remember that, as the society we live in becomes more technically advanced, the need for suitably qualified chemists will also increase. Although chemistry stands as a subject in its own right, it acts as the bond between physics and biology. Thus, by entering the world of chemistry you will be equipping yourself to play a leading role in the complex world of tomorrow.Chemistry gives you an excellent training for many jobs, both scientific and non-scientific. To be successful in the subject you need to be able to think logically, and be creative, numerate, and analytical. These skills are much sought after in many walks of life, and would enable you to pursue a career in, say, computing and finance, as well as careers which use your chemistry directly.Here is a brief outline of some of the fields chemists work in:Many are employed in the wealth-creating manufacturing industries - not just oil, chemical and mining companies, but also in ceramics, electronics and fibres. Many others are in consumer based industries such as food, paper and brewing; or in service industriessuch as transport, health and water treatment.In manufacturing and service industries, chemists work in Research and Development to improve and develop new products, or in Quality Control, where they make sure that the public receives products of a consistently high standard.Chemists in the public sector deal with matters of public concern such as food preservation, pollution control, defence, and nuclear energy. The National Health Service also needs chemists, as do the teaching profess ion and the Government‟s research and advisory establishments.Nowadays, chemists are also found in such diverse areas as finance, law and politics, retailing, computing and purchasing. Chemists make good managers, and they can put their specialist knowledge to work as consultants or technical authors. Agricultural scientist, conservationist, doctor, geologist, meteorologist, pharmacist, vet ... the list of jobs where a qualification in chemistry is considered essential is endless. So even if you are unsure about what career you want to follow eventually, you can still study chemistry and know that you‟re keeping your options open.What Do Chemistry Graduates Do?Demand for chemists is high, and over the last decade opportunities for chemistry graduates have been increasing. This is a trend that is likely to continue. Chemistry graduates are increasingly sought after to work in pharmaceutical, oil, chemical, engineering, textile and metal companies, but the range of opportunities also spans the food industry, nuclear fuels, glass and ceramics, optical and photographic industries, hospitals and the automotive industry. Many graduates begin in scientific research, development and design, but over the years, about half change, into fields such as sales, quality control, management, or consultancy. Within the commercial world it is recognised that, because of the general training implicit in a chemistry course, chemistry graduates are particularly adaptable and analytical - making them attractive to a very broad spectrum of employers. There has been a growth of opportunity for good chemistry graduates to move into the financial world, particularly in accountancy, retail stores, and computer software houses.(Summarized from: A brief of the Royal Society of Chemistry,1992)2 NOMENCLATURE OF INORGANICCOMPOUNDSNaming elementsThe term element refers to a pure substance with atoms all of a single kind. At present 107 chemical elements are known. For most elements the symbol is simply the abbreviated form of the English name consisting of one or two letters, for example:oxygen = O nitrogen = N magnesium = MgSome elements, which have been known for a long time, have symbols based on their Latin names, for example:iron = Fe (ferrum) copper = Cu (cuprum) lead = Pb (Plumbum)A few elements have symbols based on the Latin name of one of their compounds, the elements themselves having been discovered only in relatively recent times1, for example: sodium = Na (natrium = sodium carbonate)potassium = K (kalium = potassium carbonate)A listing of some common elements may be found in Table 1.Naming Metal Oxides, Bases and SaltsA compound is a combination of positive and negative ions in the proper ratio to give a balanced charge and the name of the compound follows from names of the ions, for example, NaCl, is sodium chloride; Al(OH)3is aluminium hydroxide; FeBr2is iron (II) bromide or ferrous bromide; Ca(OAc)2is calcium acetate; Cr2(SO4)3is chromium (III) sulphate or chromic sulphate, and so on. Table 3 gives some examples of the naming of metal compounds. The name of the negative ion will need to be obtained from Table 2.Negative ions, anions, may be monatomic or polyatomic. All monatomic anions have names ending with -ide. Two polyatomic anions which also have names ending with -ide are the hydroxide ion, OH-, and the cyanide ion, CN-.Many polyatomic anions contain oxygen in addition to another element. The number of oxygen atoms in such oxyanions is denoted by the use of the suffixes -ite and -ate, meaning fewer and more oxygen atoms, respectively. In cases where it is necessary to denote more than two oxyanions of the same element, the prefixes hypo- and per-, meaning still fewer and still more oxygen atoms, respectively, may be used, for example,hypochlorite ClO-Chlorite ClO2-chlorate ClO3-perchlorate ClO4-Naming Nonmetal OxidesThe older system of naming and one still widely used employs Greek prefixes for both the number of oxygen atoms and that of the other element in the compound 2. The prefixes used are (1) mono-, sometimes reduced to mon-, (2) di-, (3) tri-, (4) tetra-, (5) penta-, (6) hexa-, (7) hepta-, (8) octa-, (9) nona- and (10) deca-. Generally the letter a is omitted from the prefix (from tetra on ) when naming a nonmetal oxide and often mono- is omitted from the name altogether.The Stock system is also used with nonmetal oxides. Here the Roman numeral refers to the oxidation state of the element other than oxygen.In either system, the element other than oxygen is named first, the full name being used, followed by oxide 3. Table 4 shows some examples.Naming AcidsAcid names may be obtained directly from a knowledge of Table 2 by changing the name of the acid ion (the negative ion ) in the Table 2 as follows:The Ion in Table 2Corresponding Acid-ate-ic-ite-ous-ide-icExamples are:Acid Ion Acidacetate acetic acidperchlorate perchloric acidbromide hydrobromic acidcyanide hydrocyanic acidThere are a few cases where the name of the acid is changed slightly from that of the acid radical; for example, H2SO4 is sulphuric acid rather than sulphic acid. Similarly, H3PO4 is phosphoric acid rather than phosphic acid.Naming Acid and Basic Salt and Mixed SaltsA salt containing acidic hydrogen is termed an acid salt.A way of naming these salts is to call Na 2HPO4disodiumhydrogen phosphate and NaH2PO4sodium dihydrogenphosphate. Historically, the prefix bi- has been used innaming some acid salts; in industry, for example, NaHCO3 iscalled sodium bicarbonate and Ca(HSO3)2 calcium bisulphite.Bi(OH)2NO3, a basic salt, would be called bismuthdihydroxynitrate. NaKSO4, a mixed salt, would be calledsodium potassium sulphate.3 NOMENCLATURE OF ORGANIC COMPOUNDSA complete discussion of definitive rules of organic nomenclature would require more space than can be allotted in this text. We will survey some of the more common nomenclature rules, both IUPAC and trivial.AlkanesThe names for the first twenty continuous-chain alkanes are listed in Table 1.Alkenes and AlkynesUnbranched hydrocarbons having one double bond are named in the IUPAC system by replacing the ending -ane of the alkane name with -ene. If there are two or more double bonds, the ending is -adiene, -atriene, etc.Unbranched hydrocarbons having one triple bond are named by replacing the ending -ane of the alkane name with -yne. If there are two or more triple bonds, the ending is -adiyne, -atriyne etc. Table 2 shows names for some alkyl groups, alkanes, alkenes and alkynes.The PrefixesIn the IUPAC system, alkyl and aryl substituents and many functional groups are named as prefixes on the parent (for example, iodomethane). Some common functional groups named as prefixes are listed in Table 3.In simple compounds, the prefixes di-, tri-, tetra-, penta-, hexa-, etc. are used to indicate the number of times a substituent is found in the structure: e.g., dimethylamine for (CH3)2NH or dichloromethane for CH2Cl2.In complex structures, the prefixes bis-, tris-, and tetrakis- are used: bis- means two of a kind; tris-, three of a kind; and tetrakis-, four of a kind. [(CH3)2N]2is bis(dimethylamino) and not di(dimethylamino).Nomenclature Priority of Functional GroupsIn naming a compound, the longest chain containing principal functional group is considered the parent. The parent is numbered from the principal functional group to the other end, the direction being chosen to give the lowest numbers to the substituents. The entire name of the structure is then composed of (1) the numbers of the positions of the substituts (and of the principal functional group, if necessary); (2) the names of the substituts;(3) the name of the parent.The various functional groups are ranked in priority as to which receives the suffix name and the lowest position number1.A list of these priorities is given in Table 4.*-CKetonesIn the systematic names for ketones, the -e of the parent alkane name is dropped and -one is added. A prefix number is used if necessary.In a complex structure, a ketone group my be named in IUPAC system with the prefix oxo-. (The prefix keto- is also sometimes encountered.)AlcoholsThe names of alcohols may be: (1) IUPAC; (2) trivial; or, occasionally, (3) conjunctive. IUPAC names are taken from the name of the alkane with the final -e changed to -ol. In the case of polyols, the prefix di-, tri- etc. is placed just before -ol, with the position numbers placed at the start of the name, if possible, such as, 1,4-cyclohexandiol. Names for some alkyl halides, ketones and alcohols are listed in Table 5.EthersEthers are usually named by using the names of attached alkyl or aryl groups followed by the word ether. (These are trivial names.) For example, diethyl ether.In more complex ethers, an alkoxy- prefix may be used. This is the IUPAC preference, such as 3-methoxyhexane. Sometimes the prefix- oxa- is used.AminesAmines are named in two principal ways: with -amine as the ending and with amino- as a prefix. Names for some ethers and amines can be found in Table 6.Carboxylic AcidsThere are four principal types of names for carboxylic acids: (1) IUPAC; (2)trivial;(3)carboxylic acid; and (4)conjunctive. Trivial names are commonly used.AldehydesAldehydes may be named by the IUPAC system or by trivial aldehyde names. In the IUPAC system, the -oic acid ending of the corresponding carboxylic acid is changed to -al, such as hexanal. In trivial names, the -ic or -oic ending is changed to -aldehyde, such as benzaldehyde. Table 7 gives a list of commonly encountered names for carboxylic acids and aldehydes.Esters and Salts of Carboxylic AcidsEsters and salts of carboxylic acids are named as two words in both systematic and trivial names. The first word of the name is the name of the substituent on the oxygen. The second word of the name is derived from the name of the parent carboxylic acid with the ending changed from -ic acid to -ate.AmidesIn both the IUPAC and trivial systems, an amide is named by dropping the -ic or -oic ending of the corresponding acid name and adding -amide, such as hexanamide (IUPAC) and acetamide (trivial).Acid AnhydridesAcid anhydrides are named from the names of the component acid or acids with the word acid dropped and the word anhydride added, such as benzoic anhydride.The names for some esters, amides and anhydrides are shown in Table 8.Acid HalidesAcid halides are named by changing the ending of the carboxylic acid name from -ic acid to -yl plus the name of the halide, such as acetyl chloride.Some names of aryl compounds and aryls are as follows:benzenephenylbenzylarylbenzoic acid4. Introduction to Chemistry Department of FloridaUniversityProgram of StudyThe Department of Chemistry offers programs of study leading to the M.S. and Ph.D. degrees. Students may elect studies in analytical, inorganic, organic, and physical chemistry. Specialty disciplines, such as chemical physics and quantum, bioorganic, polymer, radiation, and nuclear chemistry, are available within the four major areas.The M.S. and Ph.D. degree requirements include a course of study, attendance at and presentation of a series of seminars, and completion and defense of a research topic worthy of publication1. Candidates for the Ph.D. degree must also demonstrate a reading ability of at least one foreign language and show satisfactory performance on a qualifying examination. The M.S. degree is not a prerequisite for the Ph.D. degree. A nonthesisdegree program leading to the M.S.T. degree is offered for teachers.Students are encouraged to begin their research shortly afterselecting a research director, who is the chairman of the supervisorycommittee that guides the student through a graduate career.Research FacilitiesThe chemistry department occupies 111,000 square feet of space in four buildings: Leigh Hall, the Chemical Research Building, Bryant Hall, and the Nuclear Science Building. Plans for a 65,000-square-foot addition to Leigh Hall are being prepared. A new central science library is located near the chemistry facilities. The University library system holds more than 2.2 million volumes.The major instrumentation includes ultraviolet-visible, infrared, fluorescence, Roman, nuclear magnetic resonance, electron spin resonance, X-ray, ESCA, and mass spectrometers. Many are equipped with temperature-control and Fourier-transform attachments, and some have laser sources. Data-storage and data-acquiring minicomputers are interfaced to some of the instruments, such as the recently constructed quadrupole resonance mass spectrometer. The chemistry department has V AX-11/780 and V AX-11/750 computers as well as multiple terminals connected to IBM machines in the main computer centre on campus.The departmental technical services include two well-equipped stockrooms and glassblowing, electronics, and machine shops to assist in equipment design, fabrication, and maintenance.Financial AidMost graduate students are given financial support in the form of teachingand research assistantships. Stipends range from $9400 - 11,000 for the1986-87 calendar year. State residents and assistantship holders pay in-statefees of about $1400 per calendar year. A limited number of full orsupplemental fellowships are available for superior candidates.Cost of StudyIn 1985-86, in-state students paid a registration fee of $48.62, per credit hour for each semester, out-of-state students paid an additional $ 94.50 ($ 143.12 per credit hour each semester). A small increase in fees is expected for 1986-87.5 ENVIRONMENTAL POLLUTIONWith the coming of the Industrial Revolution the environmentalpollution increased alarmingly. Pollution can be defined as an undesirablechange in the physical, chemical, or biological characteristics of the air, water,or land that can harmfully affect health, survival, or activities of humans orother living organisms. There are four major forms of pollution - waste onland, water pollution (both the sea and inland waters), pollution of the atmosphere and pollution by noise.Land can be polluted by many materials. There are two major types of pollutants: degradable and nondegradable. Examples of degradable pollutantsare DDT and radioactive materials. DDT can decompose slowly buteventually are either broken down completely or reduced to harmless levels. For example, it typically takes about 4 years for DDT in soil to be decomposed to 25 percent of the original level applied. Some radioactive materials that give off harmful radiation, such as iodine-131, decay to harmless pollutants. Others, such as plutonium-239 produced by nuclear power plants, remains at harmful levels for thousands to hundreds of thousands of years.Nondegradable pollutants are not broken down by natural processes. Examples of nondegradable pollutants are mercury, lead and some of their compounds and some plastics. Nondegradable pollutants must be either prevented from entering the air, water, and soil or kept below harmful levels by removal from the environment.Water pollution is found in many forms. It is contamination of water with city sewage and factory wastes; the runoff of fertiliser and manure from farms and feed lots; sudsy streams; sediment washed from the land as a result of storms, farming, construction and mining; radioactive discharge from nuclear power plants; heated water from power and industrial plants; plastic globules floating in the world‟s oceans; and female sex hormones entering water supplies through the urine of women taking birth control pills.Even though scientists have developed highly sensitive measuringinstruments, determining water quality is very difficult. There are a largenumber of interacting chemicals in water, many of them only in trace amounts.About 30,000 chemicals are now in commercial production, and each yearabout 1,000 new chemicals are added. Sooner or later most chemicals end up in rivers, lakes, and oceans. In addition, different organisms have different ranges of tolerance and threshold levels for various pollutants. To complicate matters even further, while some pollutants are either diluted to harmless levels in water or broken down to harmless forms by decomposers and natural processes, others (such as DDT, some radioactive materials, and some mercury compounds) are biologically concentrated in various organisms1.Air pollution is normally defined as air that contains one or more chemicals in high enough concentrations to harm humans, other animals, vegetation, or materials. There are two major types of air pollutants. A primary air pollutant is a chemical added directly to the air that occurs in a harmful concentration. It can be a natural air component, such as carbon dioxide, that rises above its normal concentration, or something not usually found in the air,such as a lead compound. A secondary air pollutant is a harmful chemical formed in the atmosphere through a chemical reaction among air components.We normally associate air pollution with smokestacks and cars, but volcanoes, forest fires, dust storms, marshes, oceans, and plants also add to the air chemicals we consider pollutants. Since these natural inputs are usually widely dispersed throughout the world, they normally don‟t build up to harmful levels. And when they do, as in the case of volcanic eruptions, they are usually taken care of by natural weather and chemical cycles2.As more people live closer together, and as they use machines to produce leisure, they find that their leisure, and even their working hours, become spoilt by a byproduct of their machines – namely, noise,The technical difficulties to control noise often arise from the subjective-objective nature of the problem. You can define the excessive speed of a motor-car in terms of a pointer reading on a speedometer. But can you define excessive noise in the same way? You find that with any existing simple “noise-meter”, vehicles which are judged to be equally noisy may show considerable difference on the meter.Though the ideal cure for noise is to stop it at its source, thismay in many cases be impossible. The next remedy is to absorb iton its way to the ear. It is true that the overwhelming majority ofnoise problems are best resolved by effecting a reduction in thesound pressure level at the receiver. Soft taped music in restaurantstends to mask the clatter of crockery and the conversation at thenext table. Fan noise has been used in telephone booths to maskspeech interference from adjacent booths. Usually, the problem is how to reduce the sound pressure level, either at source or on the transmission path.6 ANALYTICAL INSTRUMENT MARKETThe market for analytical instruments is showing a strength only dreamed about as little as five years ago. Driven by the need for greater chemicalanalysis coming from quality control and government regulation, arobust export market, and new and increasingly sophisticatedtechniques, sales are increasing rapidly1.The analytical instrument business' worldwides sales arenearly double their value of five years ago, reaching $ 4.1 billion in1987. Such growth is in stark contrast to the doldrums of severalyears ago when economic recession held back sales growth to littleor nothing. In recent years, the instrumentation market hasrecovered, growing at nearly 9% per year, and it‟s expected t o continue at this rate at least until the 1990. With sales increases exceeding inflation, the industry has seen the real growth demonstrating the important role of chemical instrumentation in areas such as research and development, manufacturing, defense, and the environment in a technologically advancingworld2.Chromatography is the fastest-growing area, comprising 40%, or $ 1.5billion, in 1987 world sales. Chromatographic methods are used extensively inindustrial labs, which purchase about 70% of the devices made, for separation,purification, and analysis. One of the biggest words in all forms of chromatography is “biocompatibility.” Biocompatible instruments are designed to have chemically inert, corrosion-resistant surfaces in contact with the biological samples.Gas Chromatography sales are growing at about the same rate as the instrument market.Some of the newest innovations in GC technology are the production of more instruments with high-efficiency, high-resolution capillaries and supercritical fluid capability.Despite having only a 3% share of the GC market, supercritical fluid chromatography (SFC) has attracted a great deal of attention since its introduction around 1985 and production of the first commercial instrument around 1986. SFC, which operates using asupercritical fluid as the mobile phase, bridgesthe gap between GC and HPLC. The use ofthese mobile phases allows for higherdiffusion rates and lower viscosities thanliquids, and a greater solvating powerthan gases.Another area showing tremendous growth is ion chromatography (IC). From growth levels of 30% per year in the U.S. and similar levels worldwide, the rate is expected to drop slightly but remain high at 25%. The popularity of IC has been enhanced through extending its applicability from inorganic systems to amino acids and other biological systems by the introduction of biocompatible instruments.Mass spectrometry (MS) sales have been growing about 12% annually. Sales have always been high, especially since MS is the principal detector in a number of hyphenated techniques such as GC-MS, MS-MS, LC-MS, and GC-MS accounts for about 60% of MS sales since it is used widely in drug and environmental testing. Innovations in interface technology such as inductively coupled plasma/MS, SFC/MS, and thermospray or particle beam interfaces for LC-MS have both advanced the technology and expanded the interest in applications. Recent MS instruments with automated sampling and computerized data analysis have added to the attractiveness of the technique for first time users.Spectroscopy accounts for half of all instrument sales and is the largest overall category of instruments, as the Alpert & Suftcliffe study shows. It can be broken down evenly into optical methods and electromagnetic, or nonoptical, spectroscopies. These categories include many individual high-cost items such as MS, nuclear magnetic resonance spectrometers, X-ray equipment, and electron microscopy and spectroscopy setups. Sales of spectroscopic instruments that are growing at or above the market rate include Fourier transform infrared (FTIR), Raman, plasma emission, and energy dispersive X-ray spectrometers. Others have matured and slowed down in growth, but may still hold a large share of the market.The future of analytical instrumentation does not appear to be without its new stars as there continue to be innovations and developments in existing technology. Among these are the introduction of FT Raman, IR dichroism, IR microscopy, and NMR imaging spectrometers. Hyphenated and automated apparatus are also appearing on the market more frequently. New analytical techniques like capillary electrophoresis, gel capillary electrophoresis, scanning tunneling microscopy for the imaging of conducting systems, atomic force microscopy for the imaging of biological systems, and other techniques for surface and materials analysis are already, or may soon be, appearing as commercialized instruments. And, if the chemical industry continues to do well in the next few years, so too will the sales of analytical instrumentation.The effect of alcohol have both medical and medicolegal implications. The estimationof alcohol in the blood or urine is relevant when the physician needs toknow whether it is responsible for the condition of the patient. From themedicolegal standpoint the alcohol level is relevant in cases of suddendeath, accidents while driving, and in cases when drunkenness is thedefense plea. The various factors in determining the time after ingestion showing maximum concentration and the quality of the alcohol are the weight of the subject,。

2 培养句子结构的分析能力
♦ 长句子多, 句子结构复杂是专业英语的一个语
言特征, 三年级学生虽然具备了一定的阅读能 力,但对分析复杂句子还缺乏训练。因此, 在专 业英语的教学过程中必须把这种训练贯穿到课 文教学的始终, 坚持不懈地训练, 才能收到成效。 在分析句子时应先弄清楚句子的性质, 看它是 简单句、并列句、还是复合句, 然后再进行分 析。只有把句子的结构理顺, 才能作到准确地 理解一个句子。 ♦ 笔者认为, 对句子结构的分析能力, 是一个人英 语能力的综合体现, 不是一朝一夕的事。在教 学过程中必须把这种训练贯穿到课文教学的始 终, 坚持不懈地训练, 才能收到成效。
子结构相对简单,专业英语中则常常涉及 结构较为复杂的长句,修饰成分很多,为正 确理解和翻译原文带来一定的难度。

♦ 例如,“Physics standards include color,
turbidity(混浊度,混乱度) and odor, all of which are not dangerous in themselves but could, if present in excessive amounts, drive people to drink other, perhaps less safe water. ”这句话的生 词并不多,但是插入的修饰成分较多。理解这类 句子的关键是把句的基本结构提出来,先把主句 的意思弄明白,然后逐步把其它组分的意思插入 主句,可以是条件从句、定语或状语等,应结合 中文行文习惯考虑、视句子的意思而定。

♦ 目前,各专业对专业英语教学的要求越来
越高。许多专业是新兴的、多学科交叉 的领域,新技术不断涌现,对外交流频繁。 为了能够了解、赶上世界先进技术的进 步和国外专业发展动向,本科生应该能够 熟练阅读专业文献,并在专业领域具有初 步的语言交流能力。新形式对大学生的 要求不仅是能够阅读,也应该能书写技术 文件,能够进行语言交流。
主要存在四个方面的区别
♦ 1 公共英语教学偏重根据英语的特点讲
解英语语法、时态、句型及其日常用法; 专业英语则侧重于一般性英语语法在专 业内容表达上的具体应用。

3 培养翻译能力
♦ 培养翻译能力是专业英语教学的主要目
的之一。 ♦ 在科学技术飞速发展的今天, 具备一定的 笔译能力是十分必要的。因此, 专业英语 教学的重点应该放在培养和训练学生的 翻译能力上。笔者在进行课文教学时, 要 求学生把每篇课文都要翻译成汉语
具体教学步骤
♦ a. 学习词汇, 讲解部分单词的用法。
b. 初步翻译
♦ 在这一步中, 教师对课文不作任何解释,
但要求学生在动手翻译前先通读全文, 以 便对课文有一个整体了解。这一步对训 练翻译能力十分重要,决不能把这一步当 成对课文的预习性阅读, 阅读与笔译之间 有很大的差异, 开始时, 同学们会发现有 些句子能读懂, 但很难用汉语准确地表述。 有些句子翻译出来很别扭, 不符合汉语习 惯。

♦ 与以前的大纲相比,《新大纲》首先是
内容拓宽了,它不仅要求顺利阅读、听 懂英语,以便获得专业所需的信息,同 时还要求以英语为工具获取专业信息。 ♦ 对于非英语专业的学生而言,英语水平 和能力的培养,不仅是文化素质的重要 部分,而且,在很大程度上也是能力的 补充和延伸,与基础英语相比,专业英 语显得尤为重要。
可分割的有机统一体。 ♦ 整个大学英语的教学过程,其目的就是要培养学 生今后在各自的专业岗位上具有一定的语言交 际能力。为使学生能够巩固他们在基础阶段所 形成的较强的英语阅读能力, 加强他们一定的 听和译的能力, 提高他们初步的写和说的能力, 大学高年级阶段的专业英语教学应立足于学生 在专业方面的语言交往能力。 ♦ 作为专业英语的教师,应正确认识到专业英语教 学与公共英语教学存在的区别,并在教学中采取 不同的措施,突出专业英语的教学重点,不能流 于形式,否则,容易使学生产生厌倦感。
