材料科技英语考试句子翻译复习 （1-5,1/5） 1. Material science involves investigating the relationship that exists between the structures and properties of materials. In contrast，“material engineering”is on the basis of these structure-property correlations，designing or engineering the structure of a material to produce a predetermined set of properties 材料科学是研究材料的结构和性能之间存在的关系，相反，材料工程是在这些结构性能相互关系的基础上，设计和构建材料的结构来实现一系列的预定的性能。 2. Virtually all important properties of solid materials may be grouped into six different categories：mechanical，electrical，thermal，magnetic，optical，and deteriorative 实际上，固体材料的所有重要材料可以被分成六个目录，力学，热学，磁学，光学和失效。 3. In addition to structure and properties, two other important components are involved in the science and engineering of materials，namely“processing”and “performance”. 除了结构和性质，还有两个重要的材料科学与工程的性质是材料加工材料和性能。 4. 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 工程师和科学家对于材料的各种性质特征和结构性能越熟悉，他们基于这种标准而对材料做出的明智选择将更加熟练和自信。 5. 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 只有在极少数新情况下，才能在材料的加工过程中，将各种性能最大化、理想化地结合起来，因此，权衡材料的一个性能和另一个性能是很有必要的。 (6-9,1/4) 6. An object will float in water if its density is less than the density of water and sink if its density is greater than that of water. Similarly, an object with specific gravity less than one will float and those with a specific gravity greater than one will sink. 一个物体的密度比水小时，它会浮在水上，比水大时，它会下沉。类似地，当一个物体的比重大于一，它就会上浮，比重小于一，它就会下沉。 7. Materials that cause the lines of flux to move farther apart, resulting in a decrease in magnetic flux density compared with a vacuum, are called diamagnetic. Materials that concentrate magnetic flux by a factor of more than one but less than or equal to ten a
