【作业】Heat treatment of steel 作业

1、 问题:1.     We can alter the characteristics of steel in various ways.翻译2.     Secondly, we can heat the steel above a certain critical temperature, and then allow it to cool at different rates.翻译3.     We heat the steel above the critical temperature and permit it to cool very slowly.翻译4.     Metal which we cause to cool rapidly contracts more rapidly on the outside than on the inside.   翻译5.     We therefore heat it again to a temperature below the critical temperature, and cool it slowly.  翻译

【作业】Welding 作业

1、 问题:1.     There are a number of methods of joining metal articles together, depending on the type of metal and the strength of the joint which is required. 2.     The simplest method of welding two pieces of metal together is known as pressure welding. 3.     At welding heat, the flux melts, and the oxide particles are dissolved in it together with any other impurities which may be present. 4.     The metal surfaces are pressed together, and the flux is squeezed out from the centre of the weld. 5.     The work itself constitutes one of them and the other is an insulated filler rod.

【作业】Cutting angles 翻译

1、 问题:1.This angle is essential for the elimination of friction between the flank and the newly machined surface. 翻译2.Therefore, it is sufficient to define only two of these three angles. 翻译3.The successful choice of proper values for these two angles would result in the following gains翻译4.Let us now discuss briefly how the mechanical properties of the workpiece material would affect the optimum value of the rake and clearance angles翻译5.In that case, the clearance angle is usually taken smaller than that recommended when machining soft, ductile materials翻译

Rationale for CAD-CAM 阶段测试

1、 问题:It grows out of a _ to continually improve productivity, quality, and, in turn, competitiveness
答案: 【need】
分析：【原文中表明是需求的增长 所以用need较为合适】

2、 问题:Productivity in the design process is increased by CAD/CAM. Time-consuming tasks such as mathematical calculations, data storage and retrieval, and design visualization are ______ by the computer, which gives the designer more time to spend on conceptualizing and completing the design. 
答案: 【handled
worked
soved】
分析：【原文指设计工作可以被软件取代，完成工作，所以用handled较为合适】

3、 问题:In addition, because labor-intensive tasks are performed by the computer, fewer design errors ______. These all lead to better product quality.
答案: 【occur
appear】
分析：【指设计的错误开始减少出现，所以用occur最贴切】

答案: 【hand
side
way】
分析：【指的是另一方面，常用表达方式，other side】
