Unit 1 材料的种类（1）材料的分类方法很多。
科学家常用的典型的方法是根据它们的状态分类：固体，液态或气态。
材料也分为有机（可再生）和无机材料（不可再生）。
（2）工业上，材料划分为工程材料或非工程材料。
工程材料用于制造和加工成零件的材料。
非工程材料是化学药品，燃料，润滑剂和其它用于制造又不用来加工成零件的材料。
（3）工程材料可进一步细分为：金属，陶瓷，复合材料，聚合材料，等。
Metals and Metal Alloys 金属和金属合金金属和金属合（4）金属有好的导电好导热性，很多金属有高的强度，高硬度和高的延展性。
象铁，钴，镍这些金属有磁性。
在非常低的温度下，一些金属和金属互化物变成超导体。
（5）合金和纯金属有什么区别？纯金属在元素周期表的特殊区域。
例如用于制造电线的铜和做锅和饮料罐的铝。
合金含有两种以上的金属元素。
改变金属元素的比例可以改变合金的性质。
例如，合金金属的不锈钢，是由铁，镍，和铬组成。
而黄金珠宝含有金镍合金。
（6）为什么要使用金属和合金？很多金属和合金有很高密度并用在要求质量与体积比高的的场合。
一些金属合金，象铝基合金，密度低，用在航空领域可以节省燃料。
很多合金有断裂韧度，可以承受冲击，且耐用。
金属有哪些重要属性？（7）【密度】质量除以体积叫做密度。
很多金属有相对高的密度,特别的，象聚合体。
高密度的材料常是原子量很大，象金或铅。
然而一些金属，像铝或镁密度低，就常常用在要求有金属特性而又要求低质量的场合。
（8）【断裂韧性】断裂韧度用来描述金属抗断裂的能力，特别的，当有裂纹时。
金属通常都有无关紧要的刻痕和凹坑，且有耐冲击性。
足球队员关注这一点当他确信面罩不会被击碎的时候。
（9）【塑形变形】塑性变形表述的是材料在断裂之前弯曲变形的能力。
作为工程师，我们通常设计材料使得能够在正常情况下不变形。
你不会想要一阵强烈的西风就把你的车刮得往东倾斜。
然而，有时，我们可以利用塑性变形。
汽车的承受极限就是在彻底破坏之前靠塑形变形来吸收能量。

•Types of Materials 材料的类型Materials may be grouped in several ways. Scientists often classify materials by their state: solid, liquid, or gas. They also separate them into organic (once living) and inorganic (never living) materials.材料可以按多种方法分类。
科学家常根据状态将材料分为：固体、液体或气体。
他们也把材料分为有机材料(曾经有生命的)和无机材料(从未有生命的)。
For industrial purposes, materials are divided into engineering materials or nonengineering materials. Engineering materials are those used in manufacture and become parts of products.就工业效用而言，材料被分为工程材料和非工程材料。
那些用于加工制造并成为产品组成部分的就是工程材料。
Nonengineering materials are the chemicals, fuels, lubricants, and other materials used in the manufacturing process, which do not become part of the product.非工程材料则是化学品、燃料、润滑剂以及其它用于加工制造过程但不成为产品组成部分的材料。
Engineering materials may be further subdivided into: ①Metal ②Ceramics ③Composite ④Polymers, etc.工程材料还能进一步细分为：①金属材料②陶瓷材料③复合材料④聚合材料，等等。

In many cases, however, this force must be multiplied by using an elaborate braking system.（P5）用低能机器或传力工具，操作者通过向踏板或把手的一个简单机械连接构件作用足够的力量到车闸固定的部分。
大多数情况，然而，用一个详细（复杂）的车闸系统使这个力量成倍增加。
2. The fundamental principle involved is the use of compressed air acting through a piston in a cylinder to set block brakes on the wheels. The action is simultaneous on the wheels of all the cars in the train. The compressed air is carried through a strong hose from car to car with couplings between cars; its release to all the separate block brake units, at the same time, is controlled by the engineer. (Braking Systems)（P5）相关的基本原理是使用压缩气体，通过气缸内的活塞将闸块压在车轮起作用。

第一课Text:It is known that metals are very important in our life. Metals have the greatest importance for industry. All machines and other engineering[7endVi5niEriN] constructions have metal[5metl] parts; some of them consist only of metal parts.众所周知，金属在我们的生活中是非常重要的，金属对于工业而言是有巨大的重要性，所有机器和其他工程构造都有金属零部件，其中一些还只能由金属组成。
There are two large groups of metals:1) Simple metal- more or less pure chemical elements[5elimEnt]2) Alloys[5AlCi]- materials consisting of a simple metal combined with some other elements.有两大类金属：（1）纯金属——或多或少的金属元素（2）合金——组成纯金属的原料结合其他元素。
About two thirds of all elements found in the earth are metals, but not all metals may be used in industry. Those metals which are used in industry are called engineering metals. The most important engineering metalis iron[5aiEn], which in the form of alloys with carbon[5kB:bEn] and other elements, finds greater use than any other metal. Metals consisting of iron combined with some other elements are known as ferrous[5ferEs] metals; all the other metals are called nonferrous[5nCn5ferEs] metals. The most important nonferrous metal arecopper[5kCpE], aluminum[E5lju:minEm], lead[li:d], zinc[ziNk], tin[tin], but all these metals are used muchless than ferrous metals, because the ferrous metals are much cheaper.在地球上发现的所有元素中，大约三分之二是金属元素，但是并不是所有的金属都能够用于工业上。

机械工程英语第二版全本书中英对照翻译
机械工程英语——叶邦彦第一单元•Types of Materials材料的类型Materials may be grouped in several ways. Scientists often classify materials by their state: solid, liquid, or gas. They also separate them into organic (once living) and inorganic (never living) materials.材料可以按多种方法分类。
科学家常根据状态将材料分为：固体、液体或气体。
他们也把材料分为有机材料(曾经有生命的)和无机材料(从未有生命的)。
For industrial purposes, materials are divided into engineering materials or nonengineering materials. Engineering materials are those used in manufacture and become parts of products.就工业效用而言，材料被分为工程材料和非工程材料。
那些用于加工制造并成为产品组成部分的就是工程材料。
Nonengineering materials are the chemicals, fuels, lubricants, and other materials used in the manufacturing process, which do not become part of the product.非工程材料则是化学品、燃料、润滑剂以及其它用于加工制造过程但不成为产品组成部分的材料。
Engineering materials may be further subdivided into: ①Metal ②Ceramics ③Composite ④Polymers, etc.工程材料还能进一步细分为：①金属材料②陶瓷材料③复合材料④聚合材料，等等。

Unit 12 Nanomaterial and micro-machine纳米材料与微型机械Nanomaterial [纳米材料]Nanomaterials represent today’s frontier in the development of novel advanced materials and present great promises and opportunities for a new generation of materials with improved and tailorable properties for applications in sensors, optoelectronics, energy storage, separation and catalysis.Applications of NanomaterialsThe first technological uses of these materials were as catalysts [催化剂] and pigments [颜料].In microelectronics, It would be ideal if the switching occurred with the motion of a single electron.In addition to technology, nanomaterials are also interesting systems for basic scientific investigations.Micro-machine1. IntroductionMany people may think that the smaller machines are easier to make. However, it is actually difficult to invent a small machine that will be significant to human beings. Here gives a possible reason.In addition to micro-machining, the development of micro-machines requires a number of technologies including materials, instrumentation, control, energy, information processing, and design.2. Micro-machine as Gentle MachinesThe most unique feature of a micro-machine is its small size. Micro-machines do not affect the object or the environment as much as conventional machines do. They perform their tasks gently.3. Micro-electronics and Mechatronics [机电一体化]The concept of micro-machines and related technologies is still not adequately unified , as these are still at the development stage .The micro-machines and related technologies are currently referred to by a variety of different terms.4. The Evolution of Machines and MicromachinesEver since the Industrial Revolution, machine systems have grown larger and larger in the course of their evolution.Only very recently has evolution in the opposite direction begun, with the appearance of mechatronics.The next target in miniaturization [微型化] of machine systems is miniaturization of the structural parts left untouched by present mechatronics.Notes1. Nanomaterials and nanotechnology have become a magic word in modernsociety. Nanomaterials repres ent today’s frontier in the development of novel advanced materials and present great promises and opportunities for a newgeneration of materials with improved and tailorable properties for applications in sensors, optoelectronics, energy storage, separation and catalysis.纳米材料和纳米技术已成为现代社会一个具有魔幻色彩的词汇。

Spur GearsGears , defined as toothed members transmitting rotary motion from one shaft to another , are among the oldest devices and inventions of man . In about 2600 B.C. , the Chinese are known to have used a chariot incorporating a complex series of gears . Aristotle , in the fourth century B.C. , wrote of gears as if they were commonplace . In the fifteenth century A.D. , Leonardo da Vinci designed a multitude of devices incorporating many kinds of gears .齿轮，在最古老的设备和发明人中，被定义为通过轮齿将旋转运动从一根轴传递到另一根轴，大约在公元前2600年，中国人就知道用战车组成一系列复杂的齿轮系。
西元前四世纪，亚里士多德记述了齿轮就好像是他们司空见惯的一样。
在十五世纪，达芬奇设计了大量的包含各种各样齿轮的设备。
Among the various means of mechanical power transmission (including primarily gears , belts , and chains ) , gears are generally the most rugged and durable . Their power transmission efficiency is as high as 98 percent . On the other hand , gears are usually more costly than chains and belts . As would be expected , gear manufacturing costs increase sharply with increased precision -- as required for the combination of high speeds and heavy loads , and for low noise levels . ( Standard tolerances for various degrees of manufacturing precision have been established by the AGMA , American Gear Manufacturers Association. )在众多的机械传动方式中（包括齿轮传动，带传动，链传动），一般来说，齿轮是最经久耐用的，它的能量传递效率高达98%。

The
person making the graph would look up the company's productivity for January of last year and at the productivity position on the graph for January, a point is plotted. This would then be repeated for February, March, and each month of the year. Once all points are plotted, a line or curve can be drawn through each of the points to make it clearer as to how the company did last year.
How axis motion is commanded - understanding coordinate systems It would be infeasible for the CNC user to cause axis motion by trying to tell each axis drive motor how many times to rotate in order to command a given linear motion amount. (This would be like having to figure out how many turns of the handle on a table vise will cause the movable jaw to move exactly one inch!) Instead, all CNC controls allow axis motion to be commanded in a much simpler and more logical way by utilizing some form of coordinate system. The two most popular coordinate systems used with CNC machines are the rectangular coordinate system and the polar coordinate system. By far, the more popular of these two is the rectangular coordinate system.

Lesson 12 Commercial Vehicle Emission in Perspective第12课商用车排放小组成员：061310122李明泽061310125薛继成061310126阚孟华061310127王纪伟061310128王心愿061310129陈树勇AbstractSince the difference between the gasoline engine and diesel engine , the displacement detection method for detecting different . Gasoline engine and diesel engine emissions results collected units are g / km and g / kW • h. Due to serious environmental pol lution, Passenger cars entering into service after 31 December 1992 have to comply with EC Directive 91/441/EEC and meet the conformity of production levels.After the meet EC Directive 91/542/EEC, multiplied by 50 is the emissions of 7.5 tons per hour of a truck.The 7.5 t truck is comparable with the car in terms of CO and PM and some five times worse as regards HC + NOx .On this same basis the car produces twice as much CO per litre of fuel as the truck and the diesel car produces 50% more PM per litre of fuel than the truck.As ultimately, it is the amount of fuel burned and efficiency with which it is burned that determines the overall amount of pollution created.In Britain, for example ,the UK burns the equivalent of 220×10^6t of oil every year. The total transport figure of 42.86 mtoe is made up of: rail 0.63, water 1.32, aviation 6.2 and road 34.71, with road representing 81% of total transport energy and just under 16% of the total UK energy demand. All in all, the road haulage industry is hardly a major emission culprit.In the UK,transport and economic growth are seemingly irrevocably linked,with a rise or fall of activity of one affecting the other .It is not possible to compare directly the amount of emissions put out by, say, a petrol car and a diesel bus because their engines are tested for emissions in different ways and the results given in different units.直接比较由一辆汽油轿车一辆柴油公共汽车产生的排放量是不可能的，因为它们的发动机排量的检测采用的是不同的方法，实验结果所用的单位也不同。
