【正文】 electronic structurealkaline earth metal chemical cellnuclear charge electric conductivity6. Metals are sometimes described as a lattice of positive ions surrounded by a cloud of delocalized electrons.7. Metals in general have superior electric and thermal conductivity, high luster and density, and the ability to be deformed under stress without cleaving.8. An alloy is a mixture of two or more elements in solid solution in which the major ponent is a metal.9. Combining different ration of metals as alloys modifies the properties of pure metals to produce desirable characteristics.Unit 81. 超耐熱合金的發(fā)展非常依賴于化學(xué)與加工的創(chuàng)新，并主要受到航空和能源工業(yè)的推動(dòng)。5. gross domestic product materials science and engineering market economy Societal issues economic index sanitation Gross national product popilation growth rate6. Some things that have been constant over time are human innovation and creativity, the engineer’s ability to address societal needs, and the entrepreneurial spirit of engineering.7. We have witnessed the reshaping of our lives through revolutions that hace taken place in medicine, telemunications, and transportantion industries.8. Eighteen percent of the world’s population lacks access to safe drinking water and nearly 40% has no access to sanitation. 9. Materials and society are interlinked, and it is only rational that we should see a close relation between the MSE research agenda and societal issues that affect the human condition on the globe.Unit 71. 從化學(xué)角度來說，金屬是一類容易失電子以形成正離子的元素，它與其他金屬原子形成金屬鍵。 while ductility, fracture toughness, and elongation usually decrease.8. From the respective of what is happening within a material, stress is the internal distribution of forces within a body that balance and react to the loads applied to it.9. Engineering strain is defined as the amount of deformation in the direction of the applied force divided by the initial length of the material.10. A material with high strength and high ductility will hace more toughness than a material with low strength and high ductility.Unit 61. 隨著影響我們星球上人類生存條件的社會(huì)問題的即將出現(xiàn)，材料科學(xué)與工程界有責(zé)任和機(jī)遇通過解決未來世界的需求—在能量、交通、住房、飲食、回收和健康方面的需求來改變世界。3．材料的承載方式極大地影響了材料的力學(xué)性能，也決定了材料失效形式，以及在失效前是否有預(yù)警。反磁性材料的相對(duì)導(dǎo)磁率小于1，但是到目前還沒有哪種材料的相對(duì)導(dǎo)磁率遠(yuǎn)小于1。相似的，當(dāng)比重小于1時(shí)，物體將漂浮在水面上，當(dāng)比重大于1時(shí)，物體會(huì)沉降。3． 金屬的強(qiáng)度表明原子是通過強(qiáng)的鍵結(jié)合在一起的。5. 隨著能夠觀察單個(gè)原子或者分子的掃描探針顯微鏡的出現(xiàn)，操控和移動(dòng)原子和分子以形成新結(jié)構(gòu)成為可能，因此，我們能通過一些簡單的原子水平的構(gòu)建就可以設(shè)計(jì)出新的材料。 dielectric constantSolid material(s) heat capacityMechanical property electromagnetic radiationMaterial processing elastic modulus was not until relatively recent times that scientists came to understand the relationships between the structural elements of materials and their properties.8. Materials engineering is to solve the problem during the manufacturing and application of materials.9. properties relate deformation to an applied load or force.Unit 21. 金屬是電和熱很好的導(dǎo)體，在可見光下不透明；擦亮的金屬表面有金屬光澤。，材料科學(xué)與工程還有其他兩個(gè)重要的組成部分，即加工與性能。Unit 1 Translation.1.“材料科學(xué)”涉及到研究材料的結(jié)構(gòu)與性能的關(guān)系。、結(jié)構(gòu)、性能之間的關(guān)系以及材料的加工技術(shù)，根據(jù)以上的原則，他或她就會(huì)越自信與熟練地對(duì)材料進(jìn)行更明智的選擇。2. 陶瓷是典型的導(dǎo)熱導(dǎo)電的絕緣體，并且比金屬和聚合物具有更高的耐熱溫度和耐惡劣環(huán)境性能。6. advanced materials ceramic materialshighperformance materials clay mineralsalloy implant
