1.With low-power machinery or vehicles the operator can usually apply sufficient force through a simple mechanical linkage from the pedle or handle to the stationary part of the brake. 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。列车的所有车厢上的车轮同时动作。压缩气体通过一个坚固的管道在由联轴器连接的车厢之间传输;工程师控制其在同一时间释放到所有独立的闸块单元。

3.When the brake pedal of an automobile is depressed, a force is applied to a piston in a master cylinder. The piston forces hydraulic fluid through metal tubing into a cylinder in each wheel where the fluid’s pressure moves two pistons that press the brake shoes against the drum. (Braking Systems)(P5)

当踩下汽车刹车的踏板,在主汽缸中的活塞上施加一个力。活塞驱动液压流体通过金属管道进入每个车轮气缸,在那里液压移动两个活塞将闸片压向轮圈。

4.Machinery ontology including mechanical rack, mechanical connections and mechanical transmission, which is the basis of mechanical-electrical integration, plays a role in supporting the other functional units of the system and transmitting motion and power. Compared to purely mechanical products, the performance and functionality of integration technology in electrical and mechanical systems have been improved a lot, which requires mechanical ontology to adapt its new status in mechanical structure, materials, processing technology, as well as the areas of geometry. Accordingly, the new ontology is with high efficient, multi-functional, reliable and energy-saving, small, light-weighted and aesthetically pleasing characteristics. (Mechatronics System) (P7)

机械体包括机架、机械联接和机械传动,它是机电一体化的基础,作用是支撑系统其他功能单元,传递运动和动力。和纯机械产品相比,一体化技术的性能和功能在机电系统中大幅提高,它要求机械本体适应在机械结构、材料、加工技术以及这些领域中的几何学下的新环境。相应的,新的一体化具有高效、多功能、可靠、节能、小轻和美学的令人赏心悦目的特征。

5. Detecting sensor detecting sensor part includes a variety of sensors and signal detection circuit, and its function is to detect the process of mechatronic systems in the work itself and the changes of relevant parameters in external environment and transmit the information to the electronic control unit. Electronic control unit check the information and sends the corresponding control issues to the actuator. (Mechatronics System) (P7)

检测传感器部分包括各类传感器、信号检测电路,它的功能是检测机电系统自身工作的工程,在外部环境下的相关参数的改变,将其信息传给电子控制单元。电子控制单元通过检查信息,送出相应的指令到执行机构。

6. Electronic control unit, also known as ECU, is the core of mechatronic systems, responsible for the external commands and the signals output by sensors. It centralizes stores, computes and analyzes the information. Based on the results of information processing,instruction are issued according to a certain extent and pace to control the destination for the entire system. (Mechatronics System) (P7)

电子控制单元,也被称为控制单元(ECU)控制,是机电系统的核心,负责外部命令和传

感器的信号输出。它集中、存储、计算并分析信息。基于信息处理的结果,按照一定的范围和步调发出命令来实现控制整个系统的目标。

7. It is put into a fairly standard machine tool that has had position sensing and motors on the control knobs installed. This is basically just a robot machinist. You use a rotating cutting tool to cut away all the metal that isn’t your crank. 3D metal etch-a-sketch, with the computer interpolating, so the circles come out to be pretty smooth. (CNC Machining) (P9)

将数控系统装入一个非常标准的机床,它在控制手柄上有位置感应和马达。这基本上是一个机械师。你能使用一个旋转切削刀具切掉不是你设计的所有金属。具有计算内插的三维金属蚀刻成型可以使得圆被加工得更光滑。

8. They (CNC machine) are complicated machines, full of servomechanisms, and measuring technology that can measure to 0.005mm (0.0001”) while covered in oil. A CNC machine has a minimum of 6 motors (including some to change tools, and one or more to pump oil and coolant various places). This translates to running costs that may be well over $1/minute. (The computer is not a significant part of the cost any more.) (CNC Machining) (P10)

数控机床是复杂的机器,具有伺服机构和检测技术,它能在覆盖油膜状态下检测到0.005mm。数控机床至少有6个马达(包括一些用来换刀具,一个或多个用来泵油和冷却液的各地方)。这些化成运行成本可能大大超过1美元/分钟。(电脑不再是成本的一个重要部分.)

9.Systems that can assess if the car is behaving safely can be used to warn drivers that their behavior is unsafe.In more extreme cases,the systems could override the driver and cause the car to stop or slow down.While this would on doubt save lives,it may provide a problem for the makers of films that include car chase---some of the impact may be lost when we live in a word where our cars simply refuse to do anything unsafe.

10.Another feature of the work of Dr.Ljubo Vlacic’s team is to have the machines communicate with each other.Since messages can goat the speed of light,it is possible for there to be an exchange of information on the intentions of several machines approaching an intersection.With this knowledge it should be possible to ensure that traffic flows far more smoothly.

11. Factory assembly line machinery is activated and monitored by a single PLC, where in the past hundreds of timers and relays would have been required to do the task. The machine or system user rarely, if ever, intera cts directly with the PLCs program. When it is necessary to either edit or create the PLC program, a personal c omputer is usually (but not always) connected to it. (What is aPLC?)

用一个 PLC 就能操纵和监控工厂的装配线机械,过去完成同样的工作需要成千的定时器和继电器。机器或系统用户很少,如果有的话,直接与 PLC 的程序交互。当有必要编辑或创建PLC程序时仅需将个人计算机连到 PLC 上。

12.The processes of sequencing control and interlock logic needed for automobile manufacturing was a time consuming and arduous task, which required manual updating of relays, timers and dedicated closed-loop controllers. When a new year’s model was coming

off the drawing board, skilled electricians were called on to reset the production line.(What is a PLC?) (P61)

汽车制造所需的时序控制、互锁逻辑的处理是一项耗时、费劲的工作,它需要手工更新继电器、计时器和特定的闭环控制器。当一个新年度模型脱离制图板,熟练的电工被要求从装生产线。

13. PLCs, in essence, monitor external sensory activity from additional devices.They take in the data which reports on a wide variety of activity, such as machine performance, energy output, and process impediment. They also control attached motor starters, pilot lights, values and many other devices. Both functions respond to a custom, user-created program.(What is a PLC?) (P62)

PLC,本质上是监控附加装置的外部传感活动,他们接受数据,这些数据提供广泛的活动,如机器性能、能量输出和加工障碍。它们也控制相连的马达启动器、导航灯、阀门和许多其他装置。所有的功能都对应一个惯例,实用程序。

14. They (PLCs) are designed for real-time use, and often must withstand harsh environments on the shop floor. The programmable logic controller circuitry monitors the status of multiple sensor input, which control output actuators, which may be things like motor starters, solenoid, lights and displays, or valves. (What is a PLC?) (P62)

PLC 被设计为实时应用,常常必须经受车间恶劣环境。PLC的电路检测很多传感器输入的状态,控制输出执行机构,如马达启动器、螺线管、灯、显示屏和阀门。

15. Most PLCs are programmed in a special language called Ladder https://www.sodocs.net/doc/365872408.html,dder logic is essentially a Boolean logic-solving program with a graphical user interface designed to look like an elementary wiring diagram, familiar to all industrial electricians. (What is a PLC?) (P62)

大多数的PLC都是用梯形逻辑这种特殊语言进行编程的。梯形逻辑本质是一个具有图形用户界面的布尔逻辑处理程序,,设计成一个所有的工业电气师都熟悉的基本电气线图。16. PID can be described as a set of rules with which precise regulation of a closed-loop control system is obtained. Closed loop control means a method in which a real-time measurement of the process being controlled is constantly fed back to the controlling device to ensure that the value which is desired is, in fact, being realized. (What is PID Control) (P63)

PID可以用一组规则描述,通过这组规则可获得闭环控制系统的精密调控。闭环控制是一种方法,用这种方法可将被控过程的实时检测持续地反馈给控制设备以确保期望值被实现。

17. The most important of these (PIDs), Proportional Control, determines the magnitude of the difference between the SETPOINT and the PROCESS V ARIABLE (known as ERROR), and then applies appropriate proportional changes to the CONTROL V ARIABLE to eliminate ERROR. (What is PID Control) (P63)

PID中最重要的是比例控制,它决定了设定值和过程变量间的差值,然后对控制变量使用合适的比例变量以消除误差。

18. Shafting is the machine element that supports a roller and wheel so that they can perform their basic functions of rotation. Shafting, made from round metal bars of various lengths and machined to dimension the surface, is used in a great variety of shapes and applications. Because shafts carry loads and transmit power, they are subject to the stresses and strains of operating machine parts. Standardized procedures have been evolved for determining the material characteristics and size requirements for safe and economical construction and operation. (Shafting) (P67)

轴是能支撑滚子和轮子以完成最基本的旋转运动的机械元件。轴,由各类长度的圆形金属棒料制成,被加工成各类的表面尺寸,以各种形状用于各种用途。轴因为承载和传动必经受在工作的机器零件的应力和应变。已演化出的标准流程确定安全经济结构操作所需的材料特性和尺寸要求。

19. The normal form of shafting is a solid bar. Solid shafting is obtainable commercially in round

bar stock up to 15 cm in diameter;it is produced by hot-rolling and cold-drawing or by machine-finishing with diameters in increments of 6 mm or less.For larger sizes,special rolling procedures are required,and for extremely large shafts,billets are forged to the proper shape. Particularly in solid shafting, the shaft is stepped to allow greater strength in the middle portion with minimum diameter on the ends at the bearings. The steps allow shoulders for positioning the various parts pressed onto the shaft during the rotor assembly. (Shafting) (P67)

特别是实心轴,阶梯轴允许中部有更大的强度,端部轴承处直径最小。阶梯允许轴肩在转子装置期间,通过靠在轴上来定位各类零件。

20. Differing widely in viscosity, specific gravity, vapor pressure, boiling point, and other properties, lubricants also offer a wide range of selection for the increasingly varied needs of modern industry. But whatever their derivation or properties, the purpose of lubricants is to replace dry friction with either thin-film or fluid-film friction, depending on the load, speed, or intermittent action of the moving parts. Thin-film lubrication, in which there is some contact between the moving parts, usually is specified where heavy loads are a factor. (Lubrication) (P76)

润滑剂在粘度、比重、蒸汽压、沸点和其他特性广泛不同,润滑剂为现代工业的渐长的各种需求提供广泛的选择。但无论它们的来源和特性是什么,润滑剂的目的是按移动部件的载荷、速度或间歇运动,用薄膜或流体膜摩擦取代干摩擦。薄膜润滑是指移动部件之间有部分接触,通常特指的重载荷是一个影响因素。

21.To keep the parts separated, it is necessary that the pressure within the lubricating film balances the load on the sliding surfaces. If the lubricating f ilm’s pressure is supplied by an external source, the system is said to be lubricated hydrostatically.If the pressure between the surface is generated as a result of the shape and motion of the surfaces themselves, however, the system is hydrodynamically lubricated. This second type of lubrication depends upon the viscous properties of the lubricants. (Lubrication) (P77)

要保证零件相互分离,必须是润滑油膜内的压力与滑动表面的载荷平衡。如果润滑油膜的压力是由外部源提供,则系统被称为流体静压润滑。如果表面之间的压力是由表面形状和表面运动而形成的结果,然而这系统被称为流体动压润滑。第二种润滑方法取决于润滑剂的粘性。

22. A condition that lies between unlubricated sliding and fluid-film lubrication is referred to as boundary lubrication, also defined as that condition of lubrication in which the friction between surfaces is determined by the properties of the surfaces and properties of the lubricant other than viscosity. Boundary lubrication encompasses a significant portion of lubrication phenomena and commonly occurs during the starting and stopping of machines. (Lubrication) (P77)

润滑状态介于干摩擦与油膜润滑之间的被称为边界润滑,其润滑状态也被定义为表面之间的的摩擦是由表面的特性、润滑油粘度之外的其它特性所决定的。边界润滑在润滑现象中占据相当大的比重,并且通常发生在机器启动和制动阶段。

23. Shops often overlook vibration issues when installing machine tools or equipment. However, planning for vibration control, optimally before constructing a new facility or during redesign of an existing one, can save shops a lot of money in the long run. That’s because isolating machines and processes from unwanted vibration reduces future problems such as bad part-surface finished, parts out of tolerance, and even physiological damage to shop personnel. (Isolating Unwanted Vibration)(P93)

车间常在安装机床或设备时忽视震动问题。然而,最好在构造一个新设施或从新在设计一

个现有的设施之前理想规划震动控制,这可从长远利益上为车间节省许多费用。这因为将机器和加工从有害震动中隔离可减少未来的问题,如避免低的零件表面精度,零件超公差,甚至工作人员的生理损害。

24. Some equipment manufacturers provide allowable-vibration specifications for their machines, but most don’t, which makes choosing an isolator system difficult. The key is knowing the amplitudes of vibration frequencies that harm machinery. Fabreeka reports this is where savvy companies call in a consultant or company specializing in vibration protection. (Isolating Unwanted Vibration) (P95)

部分设备制造商给机器提供震动许用指标,但多数不提供,这使得选择隔离系统困难,关键是了解损害机械的震动频率的幅值。Fabreeka报告说聪明点的公司聘请了专业做震动防护的顾问或公司。

25.Such specialists measure vibration with highly accurate instrumentation such as real-time signal analyzers. These devices capture raw data, without bias, for post-processing and quantify amplitude and frequency of vibration. With this data, the specialist recommends the best isolation solution. Engineers then conduct acceptance test measurements after installation to verify amplitudes and the resultant transmitted vibration. (Isolating Unwanted Vibration) (P95)

这类专家用高精准设备检测震动,如实时信号分析仪。这些设备不是真地捕获原始数据,为了后处理和量化震动的频率和幅值。用这些数据,专家推荐最佳的隔离方案。工程师再在安装后进行验收测试测量,验证幅值和由此产生的传送震动。

26.The tooling and grippers are not part of the robotic system itself; rather, they are attachments that fit on the end of the robot’s arm. These attachments connected to the end of the robot’s arm allow the robot lift parts, spot-weld, paint, arc-weld, drill, beburr, and do a variety of tasks, depending on what is required of the robot.(P135)

工具及夹爪并非归属于机器人系统的本身部分,而它们是装在机器人手臂端部的附件。这些与机器人手臂端部相连接的附件,能使机器人提起零件、点焊、喷漆、弧焊、钻孔、去毛刺,还可以根据所提要求执行各种类型的任务。

27.The robotic system can also control the work cell of the operating robot. The work cell of the robot is the total environment in which the robot must perform its task. Included within this cell may be the controller, the robot manipulator, a working table, safety features, or a conveyor. All the equipment that is required in order for the robot to do its job is included in the work cell. In addition, signals form outside devices can communicate with the robot in order to tell the robot when it should assemble parts, pick up parts, or unload parts to a conveyor. (Robot) (P135)

机器人系统也能控制操作机器人的工作单元。机器人的工作单元是机器人须执行其任务的总环境。在这个单元内包含有控制器、机械手、工作台、安装装置或传送带。为机器人完成该工作所需的所有设备被包括在该单元内。另外,外部设备的控制信号可和机器人通信,告知机器人何时应当装配零件、拿起零件或卸载零件到传送带。

28.At the end of the arm, a wrist is connected. The wrist is made up of addition axes and a wrist flange. The wrist flange allows the robot user to connect different tooling to the wrist for different jobs.(P136)

在手臂的端部连接着一个手腕。该手腕由附加轴及手腕法兰组成。该手腕法兰允许机器人用户根据不同的工作在手腕连接不同的工具。

1.Can We Know the Universe? - Reflections on a Grain of Salt Carl Sagan Science is a way of thinking much more than it is a body of knowledge. Its goal is to find out how the world works, to seek what regularities there may be, to penetrate to the connections of things - from sub-nuclear particles, which may be the constituents of all matter, to living organisms, the human social community, and thence to the cosmos as a whole. Our intuition is by no means an infallible guide. Our perceptions may be distorted by training and prejudice or merely because of the limitations of our sense organs, which, of course, perceive directly but a small fraction of the phenomena of the world. Even so straightforward a question as whether in the absence of friction a pound of lead falls faster than a grain of fluff was answered incorrectly by Aristotle and almost everyone else before the time of Galileo. Science is based on experiment, on a willingness to challenge old dogma, on an openness to see the universe as it really is. Accordingly, science sometimes requires courage-at the very least, the courage to question the conventional wisdom. But to what extent can we really know the universe around us? Sometimes this question is posed by people who hope the answer will be in the negative, who are fearful of a universe in which everything might one day be known. And sometimes we hear pronouncements from scientists who confidently state that everything worth knowing will soon be known - or even is already known. Let us approach a much more modest question: not whether we can know the universe or the Milky Way Galaxy or a star or a world. Can we know ultimately and in detail, a grain of salt? Consider one microgram of table salt, a speck just barely large enough for someone with keen eyesight to make out without a microscope. In that grain of salt there are about 1016 sodium and chlorine atoms. This is a 1 followed by 16 zeros, 10 million billion atoms. If we wish to know a grain of salt, we must know at least the three-dimensional positions of each of these atoms. (In fact, there is much more to be known - for example, the nature of the forces between the atoms - but we are making only a modest calculation.) Now, is this number more or less than the number of things which the brain can know? How much can the brain know? There are perhaps 1011 neurons in the brain, the circuit elements and switches that are responsible in their electrical and chemical activity for the functioning of our minds. A typical brain neuron has perhaps a thousand little wires, called dendrites, which connect it with its fellows. If, as seems likely, every bit of information in the brain corresponds to one of these connections, the total number of things knowable by the brain is no more than 1014, one hundred trillion. But this number is only one percent of the number of atoms in our speck of salt.

第三课 T1. Today we are in the throes of a worldwide reformation of cultures, a tectonic shift of habits and dreams called, in the curious vocabulary of social scientists, “globalization”. (Para.1)今天我们正经历着一种世界范围文化剧变的阵痛,一种习俗与追求的结构性变化,用社会科学家奇特的词汇来称呼这种变化,就叫“全球化”. T2. Whatever their backgrounds or agendas, these critics are convinced that Western—often equated with American—influences will flatten every cultural crease, producing, as one observer terms it, one big “McWorld”. (Para.4) 不管他们的背景和纲领如何,这些对全球化持反对态度的人深信西方的影响—往往等同于美国的影响—会把所有文化上的差异一一压平,就像一位观察家所说的,最终产生一个麦当劳世界,一个充斥美国货和体现美国价值观的世界. T3. But I also discovered that cultures are as resourceful, resilient, and unpredictable as the people who compose them. (Para.8) 不过我也发现文化就如同构成文化的民族一样,善于随机应变,富有弹性而且不可预测.

Unit 1 一个大学男孩,不清楚赚钱需要付出艰苦的劳动,被一份许诺轻松赚大钱的广告吸引了。男孩们很快就明白,如果事情看起来好得不像真的,那多半确实不是真的。 轻轻松松赚大钱 “你们该看看这个,”我向我们的两个读大学的儿子建议道。“你们若想避免因为老是向人讨钱而有失尊严的话,这兴许是一种办法。”我将挂在我们门把手上的、装在一个塑料袋里的几本杂志拿给他们。塑料袋上印着一条信息说,需要招聘人投递这样的袋子,这活儿既轻松又赚钱。(“轻轻松松赚大钱!”)“我不在乎失不失尊严,”大儿子回答说。 “我可以忍受,”他的弟弟附和道。 “看到你们俩伸手讨钱讨惯了一点也不感到尴尬的样子,真使我痛心,”我说。 孩子们说他们可以考虑考虑投递杂志的事。我听了很高兴,便离城出差去了。午夜时分,我已远离家门,在一家旅馆的房间里舒舒服服住了下来。电话铃响了,是妻子打来的。她想知道我这一天过得可好。 “好极了!”我兴高采烈地说。“你过得怎么样?”我问道。 “棒极了!”她大声挖苦道。“真棒!而且这还仅仅是个开始。又一辆卡车刚在门前停下。” “又一辆卡车?” “今晚第三辆了。第一辆运来了四千份蒙哥马利-沃德百货公司的广告;第二辆运来四千份西尔斯-罗伯克百货公司的广告。我不知道这一辆装的啥,但我肯定又是四千份什么的。既然这事是你促成的,我想你或许想了解事情的进展。” 我之所以受到指责,事情原来是这样:由于发生了一起报业工人罢工,通常夹在星期日报纸里的广告插页,必须派人直接投送出去。公司答应给我们的孩子六百美金,任务是将这些广告插页在星期天早晨之前投递到四千户人家去。 “不费吹灰之力!”我们上大学的大儿子嚷道。 “六百块!”他的弟弟应声道,“我们两个钟点就能干完!” “西尔斯和沃德的广告通常都是报纸那么大的四页,”妻子告诉我说,“现在我们门廊上堆着三万二千页广告。就在我们说话的当儿,两个大个子正各抱着一大捆广告走过来。这么多广告,我们可怎么办?” “你让孩子们快干,”我指示说。“他们都是大学生了。他们自己的事得由他们自己去做。” 第二天中午,我回到旅馆,看到一份紧急留言,要我马上给妻子回电话。她的声音高得很不自然,而且有些颤抖。家里又运到了好几卡车的广告插页。“有百货公司的,廉价商店的,杂货店的,食品店的,汽车行的,等等。有些像整本杂志那么厚。我们这里有数十万页,说不定是几百万页的广告!我们家整个房子从东墙到西墙,从南墙到北墙统统堆满了广告,一堆又一堆,比你大儿子还要高。现在只剩下一点点空间,刚够一个人走进去,从十一种插页中各取一份,卷在一起,套上橡皮筋,再塞进一只塑料袋内。我们的塑料袋足够供应全美所有的外卖餐厅!”她越讲声音越响,几乎震耳欲聋。“这么多的广告必须在星期日早晨七点以前统统送出去。”

Unit1 课程开始之际,就如何使学习英语的任务更容易提出一些建议似乎正当其时。 Some Strategies or Learning English 学习英语绝非易事。它需要刻苦和长期努力。 虽然不经过持续的刻苦努力便不能期望精通英语,然而还是有各种有用的学习策略可以用来使这一任务变得容易一些。以下便是其中的几种。 1. 不要以完全同样的方式对待所有的生词。你可曾因为简直无法记住所学的所有生词而抱怨自己的记忆力太差?其实,责任并不在你的记忆力。如果你一下子把太多的生词塞进头脑,必定有一些生词会被挤出来。你需要做的是根据生词日常使用的频率以不同的方式对待它们。积极词汇需要经常练习,有用的词汇必须牢记,而在日常情况下不常出现的词只需见到时认识即可。你会发现把注意力集中于积极有用的词上是扩大词汇量最有效的途径。 2.密切注意地道的表达方式。你可曾纳闷过,为什么我们说我对英语感兴趣是I'm 湩整敲瑳摥椠?湅汧獩屨,而说我精于法语则是???潧摯愠?牆湥档?你可曾问过自己,为什么以英语为母语的人说获悉消息或秘密是汜慥湲琠敨渠睥?牯猠捥敲屴,而获悉某人的成功或到来却是汜慥湲漠?潳敭湯?环猠捵散獳漠?牡楲慶屬?这些都是惯用法的例子。在学习英语时,你不仅必须注意词义,还必须注意以英语为母语的人在日常生活中如何使用它。 3.每天听英语。经常听英语不仅会提高你的听力,而且有助你培养说的技能。除了专为课程准备的语言磁带外,你还可以听英语广播,看英语电视和英语电影。第一次听录好音的英语对话或语段,你也许不能听懂很多。先试着听懂大意,然后再反复地听。你会发现每次重复都会听懂更多的东西。 4.抓住机会说。的确,在学校里必须用英语进行交流的场合并不多,但你还是可以找到练习讲英语的机会。例如,跟你的同班同学进行交谈可能就是得到一些练习的一种轻松愉快的方式。还可以找校园里以英语为母语的人跟他们随意交谈。或许练习讲英语最容易的方式是高声朗读,因为这在任何时间,任何地方,不需要搭档就可以做到。例如,你可以看着图片18 / 1 或身边的物件,试着对它们详加描述。你还可以复述日常情景。在商店里购物或在餐馆里吃完饭付过账后,假装这一切都发生在一个讲英语的国家,试着用英语把它表演出来。 5.广泛阅读。广泛阅读很重要,因为在我们的学习环境中,阅读是最重要、最可靠的语言输入来源。在选择阅读材料时,要找你认为有趣的、不需要过多依赖词典就能看懂的东西。开始时每天读一页是个好办法。接下去,你就会发现你每天可以读更多页,而且能对付难度更高的材料。6.经常写。写作是练习你已经学会的东西的好方法。除了老师布置的作文,你还可以找到自己要写的理由。有个笔友可以提供很好的动力;与某个跟你趣味相投但来自不同文化的人进行交流,你会学到很多东西。经常写作的其他方式还有记日记,写小故事或概述每天的新闻。 语言学习是一个积累的过程。从读和听中吸收尽量多的东西,然后再试着把学到的东西通过说和写加以运用,定会大有收益。 Unit2 弗朗西斯·奇切斯特在六十五岁时开始了只身环球航行。本文记述的就是这一冒险故事。 Sailing Round the Word 弗朗西斯·奇切斯特在独自驾船作环球航行之前,已有好几次让他的朋友们感到吃惊了。他曾试图作环球飞行,但没有成功。那是1931年。 好多年过去了。他放弃了飞行,开始航海。他领略到航海的巨大乐趣。奇切斯特在首届横渡大西洋单人航海比赛中夺魁时,已经五十八岁。他周游世界的宿愿重又被唤起,不过这一次他是要驾船环游。由于他患有肺癌,朋友们和医生们都认为他不该去,但奇切斯特决意实施自己的计划。

2、应力和应变 在任何工程结构中独立的部件或构件将承受来自于部件的使用状况或工作的外部环境的外力作用。如果组件就处于平衡状态,由此而来的各种外力将会为零,但尽管如此,它们共同作用部件的载荷易于使部件变形同时在材料里面产生相应的内力。 有很多不同负载可以应用于构件的方式。负荷根据相应时间的不同可分为: (a)静态负荷是一种在相对较短的时间内逐步达到平衡的应用载荷。 (b)持续负载是一种在很长一段时间为一个常数的载荷, 例如结构的重量。这种类型的载荷以相同的方式作为一个静态负荷; 然而,对一些材料与温度和压力的条件下,短时间的载荷和长时间的载荷抵抗失效的能力可能是不同的。 (c)冲击载荷是一种快速载荷(一种能量载荷)。振动通常导致一个冲击载荷, 一般平衡是不能建立的直到通过自然的阻尼力的作用使振动停止的时候。 (d)重复载荷是一种被应用和去除千万次的载荷。 (e)疲劳载荷或交变载荷是一种大小和设计随时间不断变化的载荷。 上面已经提到,作用于物体的外力与在材料里面产生的相应内力平衡。因此,如果一个杆受到一个均匀的拉伸和压缩,也就是说, 一个力,均匀分布于一截面,那么产生的内力也均匀分布并且可以说杆是受到一个均匀的正常应力,应力被定义为 应力==负载 P /压力 A, 因此根据载荷的性质应力是可以压缩或拉伸的,并被度量为牛顿每平方米或它的倍数。 如果一个杆受到轴向载荷,即是应力,那么杆的长度会改变。如果杆的初始长度L和改变量△L已知,产生的应力定义如下: 应力==改变长△L /初始长 L 因此应力是一个测量材料变形和无量纲的物理量 ,即它没有单位;它只是两个相同单位的物理量的比值。 一般来说,在实践中,在荷载作用下材料的延伸是非常小的, 测量的应力以*10-6的形式是方便的, 即微应变, 使用的符号也相应成为ue。 从某种意义上说,拉伸应力与应变被认为是正的。压缩应力与应变被认为是负的。因此负应力使长度减小。 当负载移除时,如果材料回复到初始的,无负载时的尺寸时,我们就说它是具有弹性的。一特定形式的适用于大范围的工程材料至少工程材料受载荷的大部分的弹性, 产生正比于负载的变形。由于载荷正比于载荷所产生的压力并且变形正比于应变, 这也说明,当材料是弹性的时候, 应力与应变成正比。因此胡克定律陈述, 应力正比于应变。 这定律服从于大部分铁合金在特定的范围内, 甚至以其合理的准确性可以假定适用于其他工程材料比如混凝土,木材,非铁合金。 当一个材料是弹性的时候,当载荷消除之后,任何负载所产生的变形可以完全恢复,没有永久的变形。

大学英语精读课文翻译 Unit 1 How to Improve Your Study Habits 你也许是个智力一般的普通学生。你在学校的学习成绩还不错,可你也许会觉得自己永远也成不了优等生。然而实际情况未必如此。你要是想取得更好的分数,也还是能做到的。是的,即使中等智力水平的学生,在不增加学习负担的情况下,也能成为优等生。其诀窍如下:1.仔细安排你的时间。把你每周要完成的任务一一列出来,然后制定一张时间表或时间分配图。先把用于吃饭、睡觉、开会、听课等这样一些非花不可的时间填上,然后再选定合适的固定时间用于学习。一定要留出足够的时间来完成正常的阅读和课外作业。当然,学习不应把作息表上的空余时间全都占去,还得给休息、业余爱好和娱乐活动留出一定的时间,这一点很重要。这张周作息表也许解决不了你所有的问题,但是它会使你比较清楚地了解你是怎样使用你的时间的。此外,它还能让你安排好各种活动,既有足够的时间工作,也有足够的时间娱乐。 2.寻找一个合适的地方学习。选定某个地方作为你的“学习区”。这可以是家里或者学校图书馆里的一张书桌或者一把椅子,但它应该是舒适的,而且不该有干扰。在你开始学习时,你应能够全神贯注于你的功课。 3.阅读之前先略读。这就是说,在你仔细阅读一篇文章之前,先把它从头至尾迅速浏览一遍。在预习材料时,你就对它的内容及其结构有了大致的了解。随后在你正式开始阅读时,你就能辨认出不太重要的材料,并且可以略去某些章节不读。略读不仅使你的阅读速度提高一倍,还有助于提高你的理解能力。< 4.充分利用课堂上的时间。上课时注意听讲意味着课后少花力气。要坐在能看得见、听得清的地方。要作笔记来帮助自己记住老师讲课的内容。 5.学习要有规律。课后要及早复习笔记。重温课堂上提到的要点,复习你仍然混淆不清的
