1.1 Metals and Non-metalsWords and termsdefinite-确定的、明确的defect-缺陷plastic deformation塑性变形stress concentrator 应力集中点self-strengthening自强化the tip of a crock裂纹尖端☐Among numerous properties possessed by materials,their mechanical properties,in the majority of cases,are the most essential and therefore,they will be given much consideration in the book.☐在一些主要应用场合,机械性能是材料的各种性能中最重要的性能,因此,本书中将重点讨论。
▪consideration 考虑,需要考虑的事项,报酬☐All critical parts and elements,of which a high reliability (可靠性)is required,are made of metals, rather than of glass,plastics or stone.☐由于各种关键零部件的可靠性要求高,均用金属而不是玻璃、塑料或石头制造。
▪is required 翻译时将英文中的被动语态,改译为汉语中的主动语态。
▪rather than 而不是☐As has been given in Sec.1-1,metals are characterized by the metallic bond(金属键),where positive ions (正离子)occupy the sites of the crystal lattice (晶格)and are surrounded by electron gas(电子云).☐正如Sec1-1中所说,金属主要由金属键组成(其特征主要……)。
