Unit 1 Chemical Industry化学工业1.Origins of the Chemical IndustryAlthough the use of chemicals dates back to the ancient civilizations, the evolution of what we know as the modern chemical industry started much more recently. It may be considered to have begun during the Industrial Revolution, about 1800, and developed to provide chemicals roe use by other industries. Examples are alkali for soapmaking, bleaching powder for cotton, and silica and sodium carbonate for glassmaking. It will be noted that these are all inorganic chemicals. The organic chemicals industry started in the 1860s with the exploitation of William Henry Perkin’s discovery if the first synthetic dyestuff—mauve. At the start of the twentieth century the emphasis on research on the applied aspects of chemistry in Germany had paid off handsomely, and by 1914 had resulted in the German chemical industry having 75% of the world market in chemicals. This was based on the discovery of new dyestuffs plus the development of both the contact process for sulphuric acid and the Haber process for ammonia. The later required a major technological breakthrough that of being able to carry out chemical reactions under conditions of very high pressure for the first time. The experience gained with this was to stand Germany in good stead, particularly with the rapidly increased demand for nitrogen-based compounds (ammonium salts for fertilizers and nitric acid for explosives manufacture) with the outbreak of world warⅠin 1914. This initiated profound changes which continued during the inter-war years (1918-1939).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）。

01. THE ELEMENTS AND THE PERIODIC TABLE 01元素和元素周期表。
The number of protons in the nucleus of an atom is referred to as the atomic number, or proton number, Z. The number of electrons in an electrically neutral atom is also equal to the atomic number, Z. The total mass of an atom is determined very nearly by the total number of protons and neutrons in its nucleus. This total is called the mass number, A. The number of neutrons in an atom, the neutron number, is given by the quantity A-Z.原子核中的质子数的原子称为原子序数，或质子数，卓电子数的电中性的原子也等于原子序数Z，总质量的原子是非常接近的总数量的质子和中子在原子核。
这被称为质量数，这个数的原子中的中子，中子数，给出了所有的数量The term element refers to, a pure substance with atoms all of a single kind. To the chemist the "kind" of atom is specified by its atomic number, since this is the property that determines its chemical behavior. At present all the atoms from Z = 1 to Z = 107 are known; there are 107 chemical elements. Each chemical element has been given a name and a distinctive symbol. For most elements the symbol is simply the abbreviated form of the English name consisting of one or two letters, for example:术语元素是指，一个纯粹的物质与一个单一的一种原子。

专业英语文献翻译Quantifying the Cluster of Differentiation 4 Receptor Density on Human T Lymphocytes Using Multiple Reaction Monitoring Mass Spectrometry。
ABSTRACT： Cluster of differentiation 4 （CD4） is an important glycoprotein containingfour extracellular domains, a transmembrane portion and a short intracellular tail. It locates on the surface of various types of immune cells and performs a critical role in multiple cellular functions such as signal amplification and activation of T cells。
It is well-known as a clinical cell surface protein marker for study of HIV progression and for defining the T helper cell population in immunological applications。
Moreover，CD4 protein has been used as a biological calibrator for quantification of other surface and intracellular proteins. However，flow cytometry, the conventional method of quantification of the CD4 density on the T cell surface depends on antibodies and has suffered from variables such as antibody clones, the ommatophore and conjugation chemistries, the fixation conditions， and the flow cytometric quantification methods used. In this study, we report the development of a highly reproducible na no liquid chromatography−multiple reaction monitoring mass spectrometry-based quantitative method to quantify the CD4 receptor density in units of copy number per cell on human CD4+ T cells. The method utilizes stable isotope—labeled full—length standard CD4 as an internal standard to measureendogenous CD4 directly, without the use of antibodies. The development of the mass spectrometry-based approach of CD4 protein quantification is important as a complementary strategy to validate the analysis from the cytometry-based conventional method。

04.GROUPS IIIB—VIIIB ELEMENTS Group I-B includes the elements scandium, yttrium, lanthanum, and actinium1, and the two rare-earth series of fourteen elements each2 —the lanthanide and actinide series. The principal source of these elements is the high gravity river and beach sands built up by a water-sorting process during long periods of geologic time. Monazite sand, which contains a mixture of rare earth phosphates, and an yttrium silicate in a heavy sand are now commercial sources of a number of these scarce elements.
B组包括元素钪，钇，镧，和actinium1，和2稀土系列十四each2镧系和锕系元素的系列。这些元素的主要来源是重力高与海滩砂建立起来的water-sorting过程在漫长的地质年代。独居石砂，其中包含一个混合稀土磷酸盐，和一个钇硅酸盐在沉沙现在商业来源的一些这些稀有元素。
Separation of the elements is a difficult chemical operation. The solubilities of their compounds are so nearly alike that a separation by fractional crystallization is laborious and time-consuming. In recent years, ion exchange resins in high columns have proved effective. When certain acids are allowed to flow down slowly through a column containing a resin to which ions of Group III B metals are adsorbed, ions are successively released from the resin3. The resulting solution is removed from the bottom of the column or tower in bands or sections. Successive sections will contain specific ions in the order of release by the resin. For example .lanthanum ion (La3+) is most tightly held to the resin and is the last to be extracted, lutetium ion (Lu3+) is less tightly held and appears in one of the first sections removed. If the solutions are recycled and the acid concentrations carefully controlled, very effective separations can be accomplished. Quantities of all the lanthanide series (except promethium, Pm, which does not exist in nature as a stable isotope) are produced for the chemical market. 分离的组成部分是一个困难的化工操作。溶解度的化合物是几乎一模一样，分离结晶是艰苦和耗时的。近年来，离子交换树脂在高列已证明有效。当某些氨基酸可以缓缓流下一列含有树脂的离子组第三金属离子吸附，先后从resin3。由此产生的解决方案是删除从塔底、塔带或部分。连续的部分将包含特定的离子释放的顺序由树脂。例如。镧离子（La 3 +）是最紧密举行的树脂，是最后被提取，镥离子（lu3+）是不那么严格，出现在第一部分被删除。如果溶液再生和酸浓度小心控制，可以实现非常有效的分离。大量的所有镧系元素（除钷，下午，它不存在的性质作为一个稳定的同位素）生产的化工市场。
The predominant group oxidation number of the lanthanide series is +3, but some of the elements exhibit variable oxidation states. Cerium forms cerium( III )and cerium ( IV ) sulfates, Ce2 (SO4 )3 and Ce(SO4 )2, which are employed in certain oxidation-reduction titrations. Many rare earth compounds are colored and are paramagnetic, presumably as a result of unpaired electrons in the 4f orbitals. 主要的氧化数为+ 3的稀土系列，但一些元素表现出不同的氧化态。铈铈（Ⅲ）形式和铈（Ⅳ）硫酸盐（SO 4）3，铈和铈（SO 4）2，其中从事某些氧化还原滴定法。许多稀土化合物，是顺磁性的，大概是由于未配对电子的轨道。
All actinide elements have unstable nuclei and exhibit radioactivity. Those with higher atomic numbers have been obtained only in trace amounts. Actinium (89 Ac), like lanthanum, is a regular Group IIIB element. 锕系元素的所有不稳定原子核和放射性。那些具有较高的原子数目已获得只有微量的。锕（89），如镧，经常是一组III B部元件。
Group IVB ElementsⅣB族元素 In chemical properties these elements resemble silicon, but they become increasingly more metallic from titanium to hafnium. The predominant oxidation state is +4 and, as with silica (SiO2), the oxides of these elements occur naturally in small amounts. The formulas and mineral names of the oxides are TiO2, rutile; ZrO2, zirconia; HfO2, hafnia.
这些元素在化学性质类似，但他们成为越来越多的金属钛铪。主要的氧化态为+ 4，与二氧化硅（SiO 2）的氧化物，这些要素自然发生少量。公式和矿物的氧化物TiO 2，金红石；氧化锆；氧化铪，锆，铪。 Titanium is more abundant than is usually realized. It comprises about 0.44% of the earth's crust. It is over 5.0% in average composition of first analyzed moon rock. Zirconium and titanium oxides occur in small percentages in beach sands.
钛是更丰富的比通常的实现。它由大约0.44%的地球的地壳。这是超过5%的平均组成，首先分析月球岩石。锆和钛的氧化物发生在小的百分比在海滩砂。
Titanium and zirconium metals are prepared by heating their chlorides with magnesium metal. Both are particularly resistant to corrosion and have high melting points.
钛、锆金属准备通过加热的氯化物与金属镁。双方尤其是耐腐蚀和具有熔点高。
Pure TiO2 is a very white substance which is taking the place of white lead in many paints. Three-fourths of the TiO2 is used in white paints, varnishes, and lacquers. It has the highest index of refraction (2.76) and the greatest hiding power of all the common white paint materials. TiO2 also is used in the paper, rubber, linoleum, leather, and textile industries.
纯TiO 2是一种白色物质，代替铅白在许多涂料。四分之三的TiO 2是用白漆，清漆，喷漆。它具有最高的折射率（2.76）和最大的遮盖力的所有常见的白色油漆材料。二氧化钛也用于纸张，橡胶，油毡，皮革，纺织工业。
