四．Translate following 3 passages into Chinese （每段20分，共60分）

1. 绘制和提交简洁、清晰的隔离体简图代表了工程交流的核心。这是真实的，因为它们是思考过程的一部分。整个思考过程包括了绘制在纸上和没有绘制在纸上的内容。这些图的绘制是将思考的结果与别人交流的唯一方式。(6分)

采用隔离体简图的好处可以总结如下：

(1）能够使人们容易地把文字、思维和观念转换为物理模型。

(2）能够帮助人们观察和理解一个问题的各个方面。

（3）能够帮助人们确定解题的途径。

（4）能够使问题的数学关系变得容易寻找。

（5）它们的应用易于记录解题的步骤，帮助做出有关简化的假设。

(6）解题所用的方法可以储存起来，供以后参考。

（7）能够帮助记忆，并且使你能够容易地向别人解释和展示你所做的工作。（10分）在分析机器中的力时，我们几乎总是需要将机器分成许多单个的部件，绘制出表明每个部件受力情况的隔离体简图。许多零部件将要通过运动副进行相互连接。（4分）

2.可能会有两种具有完全相同的强度和硬度值的金属，其中的一种由于其本身的延展性而具有很好的承受超载荷的能力。延展性是用材料断裂时的延伸率来量度的。通常将5％的延伸率定义为延展性与脆性的分界线。断裂时延伸率小于5％的材料称为脆性材料，大于5％的称为延性材料。(7分)

材料的伸长量通常是在50mm的计量长度上测量的。因为这并不是对实际应变量的测量，所以有时也采用另一种测量延展性的方法。这个方法是在试件断裂后，测量其断裂处的横截面的面积。因此，延展性可以表示为横截面的收缩率。(6分)

延性材料能够承受较大的超载荷这个特性是设计中的一个附加的安全因素。延性材料的重要性在于它是材料冷变形性能的衡量尺度。诸如弯曲和拉延这类金属加工过程需要采用延

性材料。(5分)

在选用抗磨损、抗侵蚀或者抗塑性变形的材料时，硬度通常是最主要的性能。(2分)

3. 车床主要是为了进行车外圆、车端面和钻孔等项工作而设计的机床。车削很少在其他种类的机床上进行,而且任何一种其他机床都不能像车床那样方便地进行车削加工。由于车床还可以用来钻孔和铰孔,车床的多功能性可以使工件在一次安装中完成几种加工。因此,在生产中使用的各种车床比任何其他种类的机床都多。（5分）

车床的基本部件有:床身、主轴箱组件、尾架组件、溜板组件、丝杠和光杠。（2分）床身是车床的基础件。它通常是由经过充分正火或时效处理的灰铸铁或者球墨铸铁制成。它是一个坚固的刚性框架,所有其他基本部件都安装在床身上。通常在床身上有内外两组平行的导轨。有些制造厂对全部四条导轨都采用导轨尖顶朝上的三角形导轨(即山形导轨),而有的制造厂则在一组中或者两组中都采用一个三角形导轨和一个矩形导轨。导轨要经过精密加工,以保证其直线度精度。为了抵抗磨损和擦伤,大多数现代机床的导轨是可靠性很少能像现有材料那样为人们所了解。经过表面淬硬的,但是在操作时还应该小心,以避免损伤导轨。（10分）

主轴箱安装在内侧导轨的固定位置上,一般在床身的左端。它提供动力,并可使工件在各种速度下回转。它基本上由一个安装在精密轴承中的空心主轴和一系列

2. This characteristic makes it possible to represent the locus of any chosen point of a planar mechanism in its true size and shape on a single drawing or figure.

3. Now synthesis cannot take place without both analysis and optimization because the system under design must be analyzed to determine whether the performance complies with the specifications.

4. There is much merit to the practice of one very successful company which requires that all prototypes be built with the same materials that will be used in production and, insofar as possible, with the same manufacturing techniques.

四．Translate following 3 passages into Chinese （每段20分，共60分）

1. The construction and presentation of clear and neatly drawn free-body diagrams represent the heart of engineering communication. This is true because they represent a part of the thinking process, whether they are actually placed on paper or not, and because the construction of these diagrams is the only way the results of thinking can be communicated to other.

The advantages of using free-body diagrams can be summarized as follows:

(1)They make it easy for one to translate words and thoughts and ideas into physical models.

(2)They assist in seeing and understanding all facets of a problem.

(3)They help in planning the attack on the problem.

(4)They make mathematical relations easier to see or find.

(5)Their use makes it easy to keep track of one’s progress and helps in making simplifying assumptions.

(6)The methods used in the solution may be stored for future reference.

(7)They assist your memory and make it easier to explain and present your work to others.

In analyzing the forces in machines we shall almost always need to separate the machine into its individual components and construct free-body diagrams showing the forces that act upon each component. Many of these part will be connected to each other by kinematic pairs.

2.It is possible for two metals to have exactly the same strength and hardness, yet one of these metals may have a superior ability to absorb overloads, because of the property called ductility. Ductility is measured by the percentage elongation which occurs in the material at fracture. The usual dividing line between ductility and brittleness is 5 percent elongation. A material having less than 5 percent elongation at fracture is said to be brittle, while one having more is said to be

ductile.

The elongation of a material is usually measured over 50mm gauge length. Since this is not a measure of the actual strain, another method of determining ductility is sometimes used. After the specimen has been fractured, measurements are made of the area of the cross section at the fracture. Ductility can then be expressed as the percentage reduction in cross-sectional area.

The characteristic of a ductile material which permits it to absorb large overloads is an additional safety factor in design. Ductility is also important because it is a measure of that property of a material which permits it to be cold-worked. Such operations as bending and drawing are metal-processing operations which require ductile materials.

When a material is to be selected to resist wear, erosion, or plastic deformation, hardness is generally the most important property.

3. Lathes are machine tools designed primarily to do turning, facing, and boring. Very little turning is done on other types of machine tools, and none can do it with equal facility. Because lathes also can do drilling and reaming, their versatility permits several operations to be done with a single setup of the workpiece. Consequently, more lathes of various types are used in manufacturing than any other machine tool.

The essential components of a lathe are the bed, headstock assembly, tailstock assembly, carriage assembly, and the leadscrew and feed rod.

The bed is the backbone of a lathe. It usually is made of well-normalized or aged gray or nodular cast iron and provides a heavy, rigid frame on which all the other basic components are mounted. Two sets of parallel, longitudinal ways, inner and outer, are contained on the bed, usually on the upper side. Some makers use an inverted V-shape for all four ways, whereas others utilize one inverted V and one flat way in one or both sets. They are precision-machined to assure accuracy of alignment. On most modern lathes the ways are surface-hardened to resist wear and abrasion ,but precaution should be taken in operating a lathe to assure that the ways are not damaged. Any inaccuracy in them usually means that the accuracy of the entire lathe is destroyed.

The headstock is mounted in a fixed position on the inner ways , usually at the left end of the bed. It provides a powered means of rotating the work at various speeds. it consists of hollow spindle, mounted in accurate bearings, and a set of transmission gears.

一学习总结 1理论课程学习总结人说，“走进大学就一只脚踏进了社会”，这句话没说错。上大学之前，我们有三分之二的时间在学校认真学习科学知识，缺乏自理能力，不懂人情世故。而上了大学之后，不仅要学习，还要管理好自己的生活、处理好与同学、老师的关系。所有这些都不是老师和爸妈能教会的，要靠自己在日常生活中不断的学习和总结经验教训。在大学里，有些人刻苦专研专业知识，希望将来在专业方面有所突破或能继续深造；有些人则在学好功课的基础上，发现了自己某方面的潜力，比如：较强的社交能力、体育比较好等。而大学这样一个宽松的环境正为他们提供了一个实现自我的舞台。因此，在大学里，我们不仅可以更深入的学习科学知识，还可以在业余时间挖掘自身的潜力和增强自身的特长。但不管将来你从事什么工作，首先要学好英语和用好计算机，这是形势所迫，也是现实。随着现代化步伐的加快，计算机已经成为我们进行各项工作的主要工具，而学好英语是用好计算机的基础，以后走上工作岗位，不会英语和计算机，我们将寸步难行。但有很多同学说，英语很难学，就是学不好。其实并不是不能学好，我认为没有学不会的东西，除非你不去努力或方法不对。说句实在话，学语言确实是一件比较困难的事，尤其是在一个没有相关语言环境的情况下去学。因为学语言包括听，说，读，写四个方面，要想做到这四个方面都强确实不容易。但我们可以先掌握好基础知识，再根据自己以后的发展方向决定在哪个方面进行提高。比如，你决定以后从事软件开发的工作，那你可以多看看这方面的英文版的书籍。可是，尽管英语是如此的难学，很多同学还是不以为然。许多同学进入大学后就想着如何去玩，觉得初中、高中这六年憋得实在不行了。可是放松也要有限度，不能荒废了学业，难道辛辛苦苦考上大学就是来玩的吗？因此，当我们在享受大学生活给我们带来新鲜和刺激时，不要忘了花点时间去读读单词，看看英语文章。把英语学习当成一种乐趣，而不仅仅是应付学校的考试和通过四六级。其次，就要说到计算机知识的学习了，对于我们信息管理专业来说，计算机就是我们谋生的工具。首先，我们应学会最基本的使用电脑的操作，如开机、关机、软件的安装、office的使用、电脑的日常维护等。此外，随着科学技术的日新月异的发展，网络在人们的生活中起着越来越重要的作用，不管是日常生活、交友、娱乐还是工作，人们越来越依赖于网络。因此我们还要学会上网，学会利

专业英语考试试题与答案

1.Why are cast metal sheet ingots hot-rolled first instead of being cold-rolled? Because of cold rolling is to use hot rolled steel coils as the raw material, after acid pickling to remove oxide skin for cold rolling, the finished product is hard roll, because of cold work hardening caused by deformation of continuous cold rolling hard roll strength, increase hardness, toughness and plastic index decreased, so the stamping performance will deteriorate, can only be used for simple deformation of the parts 2.What type of heat treatment is given to the rolled metal sheet after hot and “warm” rolling? What is its purpose? 轧钢的热处理的类型？轧钢热处理的目的？ Heat treatment of the main types are annealing, normalizing, quenching and tempering, solution treatment and aging treatment, cold treatment, chemical treatment, etc. Annealing： The steel is heated to a certain temperature and heat preservation for a period of time, and then make it slowly cooling, called annealing. Steel annealing is a heat the steel to the phase change or part of the phase change temperature, slow cooling after heat preservation heat treatment method. The purpose of annealing is to eliminate tissue defects, improve the organization make composition uniformity and fine grains, increase mechanical properties of the steel, reduce residual stress; Can decrease the hardness at the same time, improve the plasticity and toughness, improve machinability. So before annealing in order to eliminate and improve both the legacy of tissue defects and internal stress, and to prepare for the follow-up process, so the annealing is belong to the intermediate heat treatment, also called heat treatment in advance Normalizing： Normalizing is heated to above the critical temperature of steel, to all into homogeneous austenitic steel, heat treatment and natural cooling in air. It can eliminate hypereutectoid steel mesh cementite, for hyposteel normalizing can refine crystal lattice, improve comprehensive mechanical properties, low requirements for the parts use the normalized instead of the annealing process is more economic. Quenching: Quenching is the steel is heated to above the critical temperature, heat preservation for a period of time, then quickly into the quenching medium, the temperature plummeted, rapid cooling at greater than the critical cooling rate of speed, which is mainly composed of martensite and unbalanced heat treatment method of the organization. Can increase strength and hardness of the steel quenching, but to reduce its plasticity. That is commonly used in quenching hardening agent are: water, oil, caustic soda, and salt solution, etc
