PAGE 2 英08《冶金科技口译》(Ex) 1－Introduction to Metallurgical S&T 1.3 Listening –Note-taking –Interpreting 〔原文：英译汉 1 〕 Most metals in industry are used in combination with one or more other metals. Metals used together are called alloys. For example, steel is an iron alloy with carbon; Brass is an alloy of copper and zinc. One of the more common aluminum alloys （A4032）is used to make auto engine pistons. In addition to aluminum, this alloy contains 12.2 percent silicon, 0.9 percent copper, 1.1 percent magnesium, and 0.9 percent nickel. 〔原文：英译汉 2 〕 In the early way of smelting, the metal was probably a soft, malleable wrought iron. At some later time, the smelted iron was allowed to come into contact with charcoal. The iron perhaps absorbed carbon (possibly one percent). Later, the material became a hardened iron by fast cooling. Steel, as we call it today, was thus discovered by mixing carbon with iron. 〔原文：英译汉 3 〕 The chance discoveries in metallurgy gave us very little knowledge about their real nature or the reasons for each change. The microscope is an important tool in the laboratory. It has played a vital role in the research of metals. Perhaps 99 percent of all we know about metals today has been discovered or researched since 1864 when the microscope was used to study the crystal structure of iron by. Indeed, the microscope was the key to learning about the world of atoms and the crystal structure of metals. Nowadays, it also has led scientists to discoveries in the world of nuclear and atomic energy. 〔原文：汉译英〕 　 冶金工业包括黑色冶金工业（即：钢铁工业）和有色冶金工业两大类，是重要的原材料工业部门，为国民经济各部门提供金属材料，也是经济发展的物质基础。 新中国成立60多年来，中国的冶金工业发展迅速。在大连、天津、上海等沿海城市发展钢铁工业的同时，在内地的包头、太原、武汉、重庆、攀枝花等地建设了一批大型钢铁和铁合金、耐火材料等企业。在黑色冶金工业发展的同时，中国有色金属冶炼及加工业迅速发展起来，辽宁、黑龙江、山东、河南、四川、贵州、甘肃等地先后建设了一批大型氧化铝厂、电解铝厂和铝材加工厂。 〔参考译文：英译汉1〕 大部分使用的金属都是和一种或多种其他金属结合在一起的。这类金属称为合金。比如，钢就是铁和碳的合金；黄铜是紫铜和锌的合金。常用的铝合金之一A4032就用来制造汽车发动机活塞。 这种铝合金除了铝之外，还含有12.2%的硅，0.9%的铜，1.1%的镁，0.9%的镍。 〔参考译文：英译汉2〕 起初，熔炼的方法得到的金属是柔软的，可锻熟铁。后来，让熔融铁接触木炭。这样，铁就吸收了碳（可能是1%）。再后来，通过快速冷却得到淬火铁。这就是我们现在称作钢的材料，就是通过碳和铁的混合发现的。 〔参考译文：英译汉3〕 冶金学的偶然发现很难让我们了解每次变化的实质和原因。显微镜是实验室的重要工具，在金属的研究中起到了至关重要的作用。目前已知金属中约有99%都是在1864年用显微镜研究铁的晶体结构以来发现或研究的。 的确，显微镜曾经是了解原子世界和金属晶体结构的关键。如今，显微镜使科学家在核原子能世界有了发现。 〔参考译文：汉译英〕 Metallurgical industry consists of two categories: ferrous metallurgical industry (or: iron and steel industry) and non-ferrous metallurgical industry. It is a very important sector of raw material industry, providing all the sectors of national economy with metal materials, and it is the material foundation of economic development. For more than 60 years since the founding of the PRC (since 1949), the China’s metallurgical industry has rapidly developed. While the iron and steel industry is developing in coastal cities such as Dalian, Tianjin and Shanghai, a lot of large-sized enterprises producing iron and steel, ferroalloy, refractory materials have been established in inland cities, such as Baotou, Taiyuan, Wuhan, Chongqing and Panzhihua. Along with the rapid development of industry of ferrous metals, the melting and processing industry of non-ferrous metals is flourishing. Quite a number of large-sized factories producing alumina, electrolytic aluminum and processed aluminum products have been set up in Liaoning, Heilongjiang, Shandong, Henan, Sichuan, Guizhou and Gansu.
