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。 2．3合成法（Composition） 由两个或更多的词合成一个词，叫合成法。有时需加连字符。 如副词+过去分词well-known 著名的 名词+名词carbon steel 碳钢 rust-resistance 防锈 名词+过去分词computer-oriented 研制计算机的 介词+名词by-product 副产物 动词+副词makeup 化妆品 check-up 检查 形容词+名词atomic weight 原子量 periodic table 周期表 动词+代词+副词pick-me-up 兴奋剂 副词+介词+名词out-of-door 户外 2．4压缩法（Shortening） (1)只取词头字母 这种方法在科技英语中较常用。

Unit 21 Chemical Industry and Environment 化学工业与环境 How can we reduce the amount of waste that is produced? And how we close the loop by redirecting spent materials and products into programs of recycling? All of these questions must be answered through careful research in the coming years as we strive to keep civilization in balance with nature. 我们怎样才能减少产生废物的数量？我们怎样才能使废弃物质和商品纳入循环使用的程序？所有这些问题必须要在未来的几年里通过仔细的研究得到解决，这样我们才能保持文明与自然的平衡。 1.Atmospheric Chemistry Coal-burning power plants, as well as some natural processes, deliver sulfur compounds to the stratosphere, where oxidation produces sulfuric acid particles that reflect away some of the incoming visible solar radiation. In the troposphere, nitrogen oxides produced by the combustion of fossil fuels combine with many organic molecules under the influence of sunlight to produce urban smog. The volatile hydrocarbon isoprene, well known as a building block of synthetic rubber, is also produced naturally in forests. And the chlorofluorocarbons, better known as CFCs, are inert in automobile air conditioners and home refrigerators but come apart under ultraviolet bombardment in the mid-stratosphere with devastating effect on the earth’s stratospheric ozone layer. The globally averaged atmospheric concentration of stratospheric ozone itself is only 3 parts in 10 million, but it has played a crucial protective role in the development of all biological life through its absorption of potentially harmful shout-wavelength solar ultraviolet radiation. 1．大气化学 燃煤发电厂像一些自然过程一样，也会释放硫化合物到大气层中，在那里氧化作用产生硫酸颗粒能反射入射进来的可见太阳辐射。在对流层，化石燃料燃烧所产生的氮氧化物在阳光的影响下与许多有机物分子结合产生都市烟雾。挥发的碳氢化合物异戊二烯，也就是众所周知的合成橡胶的结构单元，可以在森林中天然产生含氯氟烃。我们所熟悉的CFCs，在汽车空调和家用冰箱里是惰性的，但在中平流层内在紫外线的照射下回发生分解从而对地球大气臭氧层造成破坏，全球大气层中臭氧的平均浓度只有3ppm，但它对所有生命体的生长发育都起了关键的保护作用，因为是它吸收了太阳光线中有害的短波紫外辐射。 During the past 20 years, public attention has been focused on ways that mankind has caused changes in the atmosphere: acid rain, stratospheric zone depletion, greenhouse warming, and the increased oxidizing capacity of the atmosphere. We have known for generations that human activity has affected the nearby surroundings, but only gradually have we noticed such effects as acid rain on a regional then on an intercontinental scale. With the problem of ozone depletion and concerns about global warming, we have now truly entered an era of global change, but the underlying scientific facts have not yet been fully established. 在过去的二十年中，公众的注意力集中在人类对大气层的改变：酸雨、平流层臭氧空洞、温室现象，以及大气的氧化能力增强，前几代人已经知道，人类的活动会对邻近的环境造成影响，但意识到像酸雨这样的效应将由局部扩展到洲际范围则是慢慢发现的。随着臭氧空洞问题的出现，考虑到对全球的威胁，我们已真正进入到全球话改变的时代，但是基本的
教学内容： Cytoplasm: The Dynamic, Mobile Factory 细胞质：动力工厂 Most of the properties we associate with life are properties of the cytoplasm. Much of the mass of a cell consists of this semifluid substance, which is bounded on the outside by the plasma membrane. Organelles are suspended within it, supported by the filamentous network of the cytoskeleton. Dissolved in the cytoplasmic fluid are nutrients, ions, soluble proteins, and other materials needed for cell functioning. 生命的大部分特征表现在细胞质的特征上。细胞质大部分由半流体物质组成，并由细胞膜（原生质膜）包被。细胞器悬浮在其中，并由丝状的细胞骨架支撑。细胞质中溶解了大量 的营养物质，离子，可溶蛋白以及维持细胞生理需求的其它物质。 The Nucleus: Information Central（细胞核：信息中心） The eukaryotic cell nucleus is the largest organelle and houses the genetic material (DNA) on chromosomes. (In prokaryotes the hereditary material is found in the nucleoid.) The nucleus also contains one or two organelles-the nucleoli-that play a role in cell division. A pore-perforated sac called the nuclear envelope separates the nucleus and its contents from the cytoplasm. Small molecules can pass through the nuclear envelope, but larger molecules such as mRNA and ribosomes must enter and exit via the pores. 真核细胞的细胞核是最大的细胞器，细胞核对染色体组有保护作用（原核细胞的遗传物质 存在于拟核中）。细胞核含有一或二个核仁，核仁促进细胞分裂。核膜贯穿许多小孔，小 分子可以自由通过核膜，而象mRNA和核糖体等大分子必须通过核孔运输。 Organelles: Specialized Work Units（细胞器：特殊的功能单位） All eukaryotic cells contain most of the various kinds of organelles, and each organelle performs a specialized function in the cell. Organelles described in this section include ribosomes, the endoplasmic reticulum, the Golgi complex, vacuoles, lysosomes, mitochondria, and the plastids of plant cells. 所有的真核细胞都含有多种细胞器，每个细胞器都有其特定功能。本节主要介绍核糖体， 内质网，高尔基体系，液泡，溶酶体，线粒体和植物细胞中的质体。 The number of ribosomes within a cell may range from a few hundred to many thousands. This quantity reflects the fact that, ribosomes are the sites at which amino acids are assembled into proteins for export or for use in cell processes. A complete ribosome is composed of one larger and one smaller subunit. During protein synthesis the two subunits move along a strand of mRNA, "reading" the genetic sequence coded in it and translating that sequence into protein. Several ribosomes may become attached to a single mRNA strand; such a combination is called a polysome. Most cellular proteins are manufactured on ribosomes in the cytoplasm. Exportable proteins and membrane proteins are usually made in association with the endoplasmic reticulum. 核糖体的数量变化从几百到几千，核糖体是氨基酸组装成蛋白质的重要场所。完整的核 糖体由大亚基和小亚基组成。核糖体沿着mRNA移动并阅读遗传密码，翻译成蛋白质。一条mRNA上可能有多个核糖体，称多聚核糖体。大多数细胞蛋白是由细胞质中核糖体生产。输出蛋白和膜蛋白通常与内质网有关。 The endoplasmic reticulum, a lacy array of membranous sacs, tubules, and vesicles, may be either rough (RER) or smooth (SER). Both types play roles in the synthesis and transport of proteins. The RER, which is studded with polysomes, also seems to be the source of the

精心整理一、元素和单质的命名 “元素”和“单质”的英文意思都是“element”，有时为了区别，在强调“单质”时可用“freeelement”。因此，单质的英文名称与元素的英文名称是一样的。下面给出的既是元素的名称，同时又是单质的名称。 或用后缀-ous表示低价，-ic表示高价。 如FeO:iron(II)oxide或ferrous oxideFe2O3:iron(III)oxide或ferric oxide Cu2O:copper(I)oxide或cuprous oxide CuO:copper(II)oxide或cupric oxide ２．化合物负电荷部分的读法： ２．１二元化合物： 常见的二元化合物有卤化物，氧化物，硫化物，氮化物，磷化物，碳化物，金属氢化物等，命名时需要使用后缀-ide， 如：fluoride，chloride，bromide，iodide，oxide，sulfide，nitride,phosphide,carbide，hydride;OH-的名称也是用后缀-ide：hydroxide， 非金属氢化物不用此后缀，而是将其看成其它二元化合物（见２。２）；非最低价的二元化合
物还要加前缀，如O22-:peroxideO2-:superoxide 举例：NaF:sodiumfluoride AlCl3:aluminiumchloride Mg2N3:magnesiumnitride Ag2S：silversulfide CaC2:calciumcarbide Fe(OH)2：iron(II)hydroxide 有些物质常用俗称，如NOnitricoxideN2Onitrousoxide ２．２非金属氢化物 除了水和氨气使用俗称water，ammonia以外，其它的非金属氢化物都用系统名称，命名规则根据化学式的写法不同而有所不同。对于卤族和氧族氢化物，Ｈ在化学式中写在前面，因此将其看成另一元素的二元化合物。 举例：HFhydrogenfluorideHClhydrogenchloride HBrhydrogenbromideHIhydrogeniodide CH4 H 高某酸 举例： H HPO3 正盐：根据化学式从左往右分别读出阳离子和阴离子的名称。 如FeSO4iron(II)sulfateKMnO4potassiumpermanganate 酸式盐：同正盐的读法，酸根中的Ｈ读做hydrogen，氢原子的个数用前缀表示。 如NaHCO3:sodiumhydrogencarbonate或sodiumbicarbonate NaH2PO4:sodiumdihydrogenphosphate 复盐：同正盐的读法，并且阳离子按英文名称的第一个字母顺序读。 如KNaCO3:potassiumsodiumcarbonate NaNH4HPO4:ammoniumsodiumhydrogenphosphate 水合盐：结晶水读做water或hydrate 如AlCl3.6H2O:aluminumchloride6-water或aluminumchloridehexahydrate AlK(SO4)212H2Oaluminiumpotassiumsulphate12-water
