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）

Elements are pure substances that cannot be decomposed into simpler substances by ordinary chemical changes. At the present time there are 109 known elements. Some common elements that are familiar to you are carbon, oxygen, aluminum, iron, copper, nitrogen, and gold. The elements are the building blocks of matter just as the numerals 0 through 9 are the building blocks for numbers. To the best of our knowledge, the elements that have been found on the earth also comprise the entire universe.

化工专业英语lesson8翻译汇编

仅供参考Lesson 8-1 Alcohol Alcohols are characterized by the presence of OH (hydroxyl group) attached to a carbon atom. Aliphatic alcohols may be considered to be derived from hydrocarbons in which an sp3 bonded hydrogen atom has been replaced with OH:R—H (Alkane) R— OH (Alcohol)They may also be considered as derivatives of water in which one of the hydrogens has been replaced with an alkyl group, R—.H—O—H (Water) R— 0—H (Alcohol)Since hydrocarbons may contain primary, secondary, or tertiary hydrogens, the same classes of alcohols are capable of existence. The following examples illustrate the typical members of each class:CH3CH2OH (CH3)2CHOH (CH3)3COHl°Alcohol 2°Alcohol 3°AlcoholEthyl alcohol (Isopropyl alcohol) (t-butyl alcohol)1. Oxidation Reaction of C—H BondAlcohols may be considered to be the first product of oxidation of the alkanes in the oxidation scheme, which eventually produces carbon dioxide and water. Alcohols might be expected to be subject to further oxidation .This has been found to be the case as long as a hydrogen atom (a -hydrogen) remains bonded to the carbon atom which has already been partially oxidized.1 The following equations illustrate the structural changes which occur; it should be emphasized that they do not illustrate the mechanistic steps of the reactions [(1) and (2)].The above reaction involve the C—H bond. Since 3° alcohol have no a-hydrogen atom bonded to the partially oxidized carbon atom, they resistant to further oxidation.2. Reaction of O—H BondThe proton bonded to oxygen of an alcohol is much more acidic than protons bonded to carbon. This difference can be readily accounted for on the greater electronegativity of oxygen, which polarizes the 0—H bond." The hydrogen on oxygen is replaceable by sodium for example (3).This reaction is analogous to the liberation of hydrogen by reaction of an acid and a metal. The order of reactivity of alcohols in this reaction is : l°>2°>3°.The reason for this order of reactivity is believed to be the result of the inductive effects of alkyl groups. Utilizing the relative electronegativity value of 2.1 for hydrogen and 2.5 for carbon, the H—C may be represented as follows: Hδ+ -> Cδ-. Thus, the larger the number of such bonds, as in the i-butyl group, the greater the combined electron release effect would be expected.® As the combined electronrelease effect increases, the greater the destabilizing effect on the alkoxide anion, which thus accounts for the observed order of reactivity: 1°>2°>3°.Lesson 8-1 Alcohol醇的特点是碳原子上连接着羟基。
