材料科学与工程专业英语第三版-翻译以及答案UNIT 1一、材料根深蒂固于我们生活的程度可能远远的超过了我们的想象，交通、装修、制衣、通信、娱乐(recreation)和食品生产，事实上(virtually)，我们生活中的方方面面或多或少受到了材料的影响。

历史上，社会的发展和进步和生产材料的能力以及操纵材料来实现他们的需求密切(intimately)相关，事实上，早期的文明就是通过材料发展的能力来命名的(石器时代、青铜时代、铁器时代)。

二、早期的人类仅仅使用(access)了非常有限数量的材料，比如自然的石头、木头、粘土(clay)、兽皮等等。

随着时间的发展，通过使用技术来生产获得的材料比自然的材料具有更加优秀的性能。

这些性材料包括了陶瓷(pottery)以及各种各样的金属，而且他们还发现通过添加其他物质和改变加热温度可以改变材料的性能。

此时，材料的应用(utilization)完全就是一个选择的过程，也就是说，在一系列有限的材料中，根据材料的优点来选择最合适的材料，直到最近的时间内，科学家才理解了材料的基本结构以及它们的性能的关系。

在过去的100年间对这些知识的获得，使对材料性质的研究变得非常时髦起来。

因此，为了满足我们现代而且复杂的社会，成千上万具有不同性质的材料被研发出来，包括了金属、塑料、玻璃和纤维。

三、由于很多新的技术的发展，使我们获得了合适的材料并且使得我们的存在变得更为舒适。

对一种材料性质的理解的进步往往是技术的发展的先兆，例如:如果没有合适并且没有不昂贵的钢材，或者没有其他可以替代(substitute)的东西，汽车就不可能被生产，在现代、复杂的(sophisticated)电子设备依赖于半导体(semiconducting)材料四、有时，将材料科学与工程划分为材料科学和材料工程这两个副学科(subdiscipline)是非常有用的，严格的来说，材料科学是研究材料的性能以及结构的关系，与此相反，材料工程则是基于材料结构和性能的关系，来设计和生产具有预定性能的材料，基于预期的性能。

《材料科学与工程专业英语》Unit1 Materials Science and Metallurgical EngineeringMaterials are properly more deep-seated in our culture than most of us realize. Trans -portation, 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' abilities to produce and manipulate materials to fill their needs. In fact, early civilizations have been designated by the level of their materials development (i.e.Stone Age, Bronze Age).The earliest humans has 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 properties superior 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 is, deciding from a given, rather limited set of materials the one that was best suited for an application by virtue of its characteristic. It 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 in the past 60 years or so, 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 characteristics that meet the needs of our modern and complex society.The development of many technologies that make our existence so comfortable has been intimately associated with the accessibility of suitable materials. Advancement in the under--standing of a material type is often the forerunner to the stepwise progression of a technology. For example, automobiles would not have been possible without the availability of inexpensive steel of some other comparable substitutes. In our contemporary era, sophisticated electronic devices rely on components that are made from what are called semiconducting materials.Materials Science EngineeringMaterials science is an interdisciplinary study that combines chemistry, physics, metallurgy, engineering and very recently life sciences. One aspect of materials science involves studying and designing materials to make them useful and reliable in the service of humankind. It strives for basic understanding of how structures and processes on the atomic scale result in the properties and functions familiar at the engineering level. Materials scientists are interested in physical and chemical phenomena acting across large magnitudes of space and time scales. In this regard it differs from physics of chemistry where the emphasis is more on explaining the properties of pure substances. In materials science there is also an emphasis on developing and using knowledge to understand how the properties of materials can be controllably designed by varying the compositions, structures, and the way in which the bulk and surfaces phase materials are processed.In contrast, materials engineering is, on the basis of those structure properties correlations, designing or engineering the structure of a material to produce a predetermined set of properties. In other words, materials engineering mainly deals with the use of materials in design and how materials are manufactured."Structure" is 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 large 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. For example, a specimen subject 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 s 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 filed. 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 electromagnetic 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, namely "processing" and "performance". With regard to the relationships of these four components, the structure of a material will depend on how it is processed. Furthermore, a material's performance will be a function of its properties. Thus, the interrelationship between processing, structure, properties, and performance is linear as follows:Processing→Structure→Properties→PerformanceWhy Study Materials Science and Engineering?Why do we study materials? Many an applied scientists or engineers, whether mechanical, civil, chemical, or electrical, will be exposed to a design problem involving materials at one time or another. Examples might include a transmission gear, the superstructure for a building, an oil refinery component, or an integrated circuit chip. Of course, materials scientists and engineers are specialists who are totally involved in the investigation and design of materials.Many times, a materials problem is to select the right material from many thousands available ones. There are several criteria on which the final decision is normally based. First of all, the in-service conditions must be characterized. On only rare occasion does a material possess the maximum or ideal combination of properties. Thus, it may be necessary to trade off one characteristic for another. The classic example involves strength and ductility; normally, a material having a high strength will have only a limited ductility. In such cases a reasonable compromise between two or more properties may be necessary.A second selection consideration is any deterioration of material properties that may occur during service operation. For example, significant reductions in mechanical strengthmay result from exposure to elevated temperatures or corrosive environments.Finally, probably the overriding consideration is economics. What will the finished product cost? A material may be found that has the ideal set of properties, but is prohibitively expensive. Here again, some compromise is inevitable. The cost of a finished piece also includes any expense incurred during fabrication.The more familiar an engineer or scientist is with the various characteristics and structure-property relationships, as well as processing techniques of materials, the more proficient and confident he or she will be to make judicious materials choices based on these criteria.(Selected from Materials Science and Engineering: AnIntroduction, by William D Callister,2002)New Words and Expressionspottery n. 陶瓷by virtue of 依靠（……力量），凭借，由于，因为empower vt.授权，准许，使能够empower sb.to do sth. 授权某人做某事forerunner n. 先驱（者），传令官，预兆stepwise a. 逐步地，分阶段地interdisciplinary a. 交叉学科的metallurgy n. 冶金学nebulous a. 星云的，云雾状的，模糊的，朦胧的agglomerate n. 大团，大块；a.成块的，凝聚的elaboration n. 详尽的细节，解释，阐述electrical conductivity 电导性，电导率dielectric constant 介电常数thermal conductivity 热导性，热导率heat capacity 热容refraction n. 衍射reflectivity n. 反射ductility n. 延展性corrosive a. 腐蚀的，蚀坏的，腐蚀性的；n. 腐蚀物，腐蚀剂overriding a. 最重要的；高于一切的prohibitive a. 禁止的，抵制的judicious a. 明智的criterion n. 标准，准则，尺度Notes1.
