同济大学专业英语课后翻译
1、Many problems, by their very nature, can’t be fully described—even after the fact, much less at the outset. Yet acceptable engineering solutions to these problems must be found which satisfy the defined needs. Engineering, then, frequently concerns the determination of possible solutions within a context of limited data. Intuition or judgment is a key factor in establishing possible alternative strategies, processes, or solutions. And this, too, is all a part of engineering.很多的问题，就其本身的性质而言，不能完全被描述——即使这一事实，在其开始之前。然而还必须找到对于这些问题可接受的工程解决方案，来满足预定的需求。直觉或判断是建立可能的替代策略、流程或解决方案的关键因素。。而这也是工程的一部分。
2、In ancient Egypt the simplest mechanical principles and devices were used to construct many temples and pyramids that are still standing, including the great pyramid at Giza and the temple of Amon-Ra at Karnak. 古埃及人用最简单的机械原理和装置建造了许多至今仍矗立的庙宇和金字塔，包括吉萨大金字塔和在卡纳克的Amon-Ra的寺庙。
The term “civil engineer” did not come into use until about 1750, 直到大约1750年，人们才开始使用“土木工程师”这一术语。
3、Steel, basically an alloy of iron and a small amount of carbon, had been made up to that time by a laborious process that restricted it to such special uses as sword blades. 直到那个时候，钢材才通过繁复的过程制造出来，基本上是铁合金，并含有少量的碳，因而被限制在一些特殊的用途如刀刃。
4、New alloys have further increased the strength of steel and eliminated some of its problems, such as fatigue, which is a tendency for it to weaken as a result of continual changes in stress新的合金进一步提高了钢材的强度，并消除了一些缺点，如疲劳，即在连续的应力变化下导致强度减弱的趋势。
5、Concrete is very versatile; it can be poured, pumped, or even sprayed into （喷射成）all kinds of shapes. 混凝土的用途很多，可以浇筑、泵送甚至喷射成各种形状。
6、They have become curtain walls, which keep out the weather and let in light. 它们成为幕墙，将日晒风吹雨打阻挡在外，而让光线进入
7、A rivet is a bolt with a head that looks like a blunt screwwithout threads. It is heated, placed in holes through the pieces of steel, and a second head is formed at the other end by hammering,it to hold it in place铆钉是个有头的螺栓，看上去象个没有螺纹的圆头螺丝钉。铆钉加热后穿过钢构件之间的孔洞，并通过锤击另一端而形成第二个铆钉头，从而将其固定就位。
8、In the other (and more common) method, the prestressed steel rods are placed in the lower part of a form that corresponds to the shape of the finished structure, and the concrete is poured around them. 另一种（更常用的）方法是将预应力钢筋置于按成品结构的形状设置的模板的较低部位，然后将混凝土倒入（模板）而包围着钢筋。
9、Prestressed concrete has made it possible to developbuildings with unusual shapes, like some of the modern sports arenas, with large space unbroken by any obstructing supports. 预应力混凝土使建造独特形状的建筑物成为可能，象一些现代的运动场，它具有不受任何支撑物阻挡视线的大空间。
10、In some locations, some lightweight aggregates cost little more than the best dense aggregates and a large number of floor slabs have therefore been built of lightweight aggregate concrete purely for its weight saving, with no thought of its insulation value.
在某些地区，一些轻质骨料的费用几乎等于最致密的骨料，因此大量的楼面板采用轻骨料混凝土制作纯粹是节约重量，而没考虑它的绝热价值。
11、The lightweight aggregate reduces the floor dead load by about 20 per cent resulting in
considerable savings in the floor steel in every floor and the roof, as well as in the column steel and (less) in the foundations. 轻质骨料使楼面的恒载减少了约20%，因而大量的节约了每层楼面以及屋面的楼盖结构中的钢材和柱子与基础中（较少）的钢材使用量。
12、However, it may be very costly to produce parts that have nonstandard sizes, so it is usually more economical to waste some material by selecting the nextlarger standard size above that required by the allowable stress. 但是，生产非标准尺寸部件的成本可能很高，因此，通常人们会选择比按许用应力要求的尺寸大一些的标准尺寸部件，这样尽管浪费了一些材料，但总体上更经济。
13、However, becoming familiar with superposition was more important than finding solutions to the problems because superposition has application in many areas of stress analysis and will be used frequently in our future studies. 但是，熟悉叠加法远比找到问题的答案重要，因为叠加法已经用于应力分析的很多领域，而且，在我们今后的研究中还会经常使用。
14、However, it has already been pointed out that in most applications a member would be unserviceable due to excessive distortion long before it actually ruptured但是，在多数应用中已经被指出，一个构件早在它实际断裂之前由于过分的变形而不再适用。
15、In engineering practice, if it becomes doubtful as to how to model a structure or transfer the loads to the members, it is best to consider several idealized structures and loadings and then design the actual structure so that it can resist the loadings in all the idealized models. 在工程实践中，如果就怎样模拟一个结构或将荷载传递给构件变得难以确定时，最好考虑几个理想的结构和荷载，然后设计实际的结构，使它在所有理想的模型中都能抵抗荷载。
16、As a general rule, a structure can be identified as being either statically determinate or statically indeterminate by drawing free-body diagrams of all its members, or selective parts of its members, and then comparing the total number of unknown reactive force and moment components with the total number of available equilibrium equations. 作为一般的规律，一个结构可以通过画出所有构件或经选择的部分构件的隔离体图，然后比较未知的反力和弯矩的分量总数目与可用的平衡方程总数目是否相等来确定其是静定结构还是超静定结构。
17、Theorem 2: The deviation of the tangent at point B on the elastic curve with respect to the tangent at point A equals the “moment”of the M / EI diagram between the two points A and B computed about point A (the point on the elastic curve), where the deviation tA/B is to be determined. 定理2：弹性曲线上B点的正切相对于A点的正切的偏差等于点A与点B之间的M / EI图对A点（该点在弹性曲线上）的矩，这里偏差tA/B将被确定。
18、In general, these displacements do not have to be elastic, and they may not be related to the loads; however, the external and internal displacements must be related by the compatibility of the displacements一般来说，这些位移不必是弹性的，它们可能与荷载无关。但是外部位移与内部位移必须通过位移协调联系起来。
19、If the displacement of a point is to be determined, the theorem states that it is equal to the first partial derivative of the strain energy in the structure with respect to a force acting at a point and in the direction of displacement. 如果要确定某一点的位移，该定理表明位移等于结构中的应变能对于作用在该点并沿该位移方向的力的一阶偏导数。
20、The universal nature of reinforced concrete construction stems from the wide availability of reinforcing bars and the constituents of concrete, gravel,sand, and cement, the relatively simple skills required in concrete construction, and the economy of reinforced concrete compared to other form of construction. 钢筋混凝土建筑物通用的特性归因于能大量得到钢筋和混凝土的组分（即碎石、砂和水泥），混凝土施工需要相对简单的技术，以及与其他形式的建筑相比钢筋
混凝土的经济性
21、the moments due to applied loads are resisted by an internal tension-compression couple involving tension in the concrete. 外力引起的力矩由内部的拉-压形成的力偶来抵抗，此力偶中包含了混凝土的拉力。
22、In a reinforced concrete beam, steel bars are embedded in the concrete in such a way that the tension forces needed for moment equilibrium after the concrete cracks can be developed in the bars. 在钢筋混凝土梁中，钢筋埋置在混凝土内的方式应能使混凝土开裂后在钢筋中产生平衡力矩所需的拉力。
23、The structure in a building must withstand the effects of a fire and remain standing while the building is evacuated and the fire is extinguished 当房屋被撤空、火被熄灭时，建筑中的结构必须经得起火的影响，并仍能保持直立

第一章汽车总论 1)Today’s average car contains more than 15,000 separate, individual parts that must work together. These parts can be grouped into four major categories: body, engine, chassis and electrical equipment 。P1 现在的车辆一般都由15000多个分散、独立且相互配合的零部件组成。这些零部件主要分为四类：车身、发动机、底盘和电气设备。 2)The engine acts as the power unit. The internal combustion engine is most common: this obtains its power by burning a liquid fuel inside the engine cylinder. There are two types of engine: gasoline (also called a spark-ignition engine) and diesel (also called a compression-ignition engine). Both engines are called heat engines; the burning fuel generates heat which causes the gas inside the cylinder to increase its pressure and supply power to rotate a shaft connected to the power train. P3 发动机作为动力设备，常见的类型是内燃机，其原理是通过发动机缸内的液体燃料燃烧而产生能量。发动机可分为两类：汽油机（点燃式）和柴油机（压燃式），都属于热力发动机。燃料燃烧产生热量使缸内气压上升，产生的能量驱动轴旋转，并传递给动力传动系。 第二章内燃机 1)Power train system: conveys the drive to the wheels 2)Steering system: controls the direction of movement 3)Suspension system: absorbs the road shocks 4)Braking system: slows down the vehicle P4 传动系把发动机输出的扭矩传递给驱动轮。传动系包括离合器（对应机械变速器）或液力变矩器（对应液力自动变速器）、变速器、驱动轴、主减速器、差速器和驱动桥。 5)Drum brakes have a drum attached to the wheel hub, and braking occurs by means of brake shoes expanding against the inside of the drum. With disc brakes, a disc attached to the wheel hub is clenched between two brake pads. P6 鼓式制动器的制动鼓和轮毂连接，制动蹄张开压紧制动鼓内侧从而产生制动。在盘式制动器上，连着轮毂的制动盘被紧紧夹在两个制动块之间。 1)Linking the piston by a connecting rod to a crankshaft causes the gas to rotate the shaft through half a turn.The power stroke"uses up"the gas,so means must be provided to expel the burnt gas and recharge the cylinder with a fresh petrol-air mixture:this control of gas movement is the duty of the valves;An inlet valve allows the mixture to enter at the right time and an exhaust valve lets out the burnt gas after the gas has done its job . P10 活塞通过连杆和曲轴连接，使得气体带动曲轴旋转半圈。作功冲程耗尽了所有的气体，这样就必须采取相应的措施排出废气并且向气缸内充入新的可燃混合气：气体的运动由气门来控制。进气门使可燃混合气在恰当的时刻进入气缸，排气门使燃烧后的废气排出气缸。 2)The spark-ignition engine is an internal-combustion engine with externally supplied in ignition,which converts the energy cntained in the fuel to kinetic energy.The cycle of operations is spread over four piston strokes. To complete the full cycle it takes two revolutions of the crankshaft. P11 火花点火式发动机是由外部提供点火的内燃机，从而将含在燃料内的能量转化成动能。发动机的一个工作循环分布在活塞的四个行程中，一个完整的工作循环曲轴需要转动两圈。 3)The oil pump in the lubricating system draws oil from the oil pan and sends it to all working parts in the engine. The oil drains off and runs down into the pan. Thus,there is constant circulation of oil between the pan and the working parts of the engine. P15

大学英语精读1课文翻译 Unit1 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 interested in English"，而说"我精于法语"则是"I'm good at French"？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"learn the news or secret"，而"获悉某人的成功或到来"却是"learn of someone's success or arrival"？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。

About car engine Of all automobile components,an automobile engie is the most complicated assembly with dominant effects on the function of an autombile.So, the engine is generally called the"heat"of an automobile. 在汽车的所有部件中，汽车发动机是最复杂的组件，其对整车性能有着决定性的作用。因而发动机往往被称作发动机的“心脏”。 There are actually various types of engines such as electric motors,stream engines,andinternal combustion engines.The internal combustion engines seem to have almost complete dominance of the automotive field.The internal combustion engine,as its name indicates,burns fuel within the cylinders and converts the expanding force of the combustion into rotary force used to propel the vehicle. 事实上，按动力来源分发动机有很多种，如电动机、蒸汽机、外燃机等。然而内燃机似乎在发动机领域有着绝对的统治地位。就像其字面意思一样，内燃机的染料在气缸内燃烧，通过将燃烧产生气体的膨胀力转换成转动力来驱动发动机前进。 Engine is the power source of the automobile.Power is produced by the linear motion of a piston in a cylinder.However,this linear motion must be changed into rotary motion to turn the wheels of cars or trucks.The puston attached to the top of a connecting rod by a pin,called a piston pin or wrist pin.The bottom of the connecting rod is attached to the crankshaft.The connecting rod transmits the up-and-down motion of the piston to the crankshaft,which changes it into rotary motion.The connecting rod is mounted on the crankshaft with large bearings called rod bearing.Similar bearings, called main bearings,are used to mount the crankshaft in the block. 发动机是整部车的动力来源。能量来自于活塞在气缸内的（往复）直线运动。然而这种（往复）直线运动必须要转换成旋转运动才能驱动车轮。活塞与连杆通过一个销来连接，这个销称为活塞销。连杆的下部连接于曲拐。连杆把活塞的上下往复运动传递给曲拐，从而将往复直线运动转变成旋转运动。连杆和曲拐的连接使用大的轴承，称之为连杆轴承，类似的轴承也用于将曲轴连接到机体，称之为主轴承。 They are generally two different types of cooling system:water-cooling system and air-cooling system.Water-cooling system is more common.The cooling medium, or coolant, in them is either water or some low-freezing liquid, called antifreeze.A water-cooling system consists of the engine water jacket, thermostat, water pump, radiator, radiator cap, fan, fan drive belt and neccessary hoses. 主要有两种类型的冷却系统：水冷和风冷。水冷系统更为普遍。系统所用冷却介质或是冷却液常委水或其他低凝固点液体，称为抗凝剂。一个完整的水冷系统包括机体水套，节温器，水泵，散热器，散热器罩，风扇，风扇驱动皮带和必需的水管。 A water-cooling system means that water is used as a cooling agent to circulate through the engine to absorb the heat and carry it to the radiator for disposal.The ebgine is cooled mainly through heat transfer and heat dissipation.The heat generated by the mixture burned in the engine must be transferred from the iron or aluminum cylinder to the waterin the water jacket.The outside of the water jacket dissipates some of the heat to the air surrounding it, but most of the heat is carried by the cooling water to the radiator for dissipation.When the coolant temperature in the system reaches 90°,the termostat valve open fully, its slanted edge shutting off

“数学专业英语一次函数专题”教学设计 1. 教学内容及解析 教学内容：与直角坐标系及一次函数相关的英语文献资料 内容解析：本节内容应从两个方面去考虑. 一方面，从数学知识的角度，本节所涉及的是从平面直角坐标系到一次函数的数学知识，都是学生学过的基础知识及其应用，是对于这些知识的拉练式复习，并作为后面用英语叙述解答相关问题知识基础；另一方面，从语言的角度，学生会接触到大量没有接触过，但他们却很熟悉的英语词汇及短语，主动学习的学生可以在老师的指导下快速理解其含义并加入到自己的知识体系中，但需要花时间巩固，是需要读、写、说来巩固的内容. 这也正是本节的重点和难点所在. 2. 教学目标及解析 教学目标：①能根据已有的数学知识和给出的单词对照表，将给出的相关数学定理及结论的英语版本翻译为中文；②能理解并解答用英语表述的相关数学问题；③能将解决数学问题的过程用英语进行书面表述；④初步了解用英语表达与直角坐标系及一次函数相关数学理论的范式. 目标解析：学生掌握基本词汇，并能阅读与本节内容相关的英语文献，是学习和使用数学专业英语的最基本要求，学生需要在学习的过程中逐渐由接受，即阅读或聆听，逐渐向输出，即书面和口头表达的方向发展. 为达到此目标，学生需要在课前独立完成对于本节需要的单词的学习，并阅读一系列简短的相关数学文献，并在这个过程中初步体会数学专业英语的表达范式；在课堂上，在教师的指导下对自己的认知进一步补充，并进行一定量的练习，暴露自己的问题，在教师的帮助下修正问题，完善认知. 3. 教学问题诊断分析 学生在进行语言表达时，往往受到母语的限制，对于非母语的表达方式的接受能力一时难以习惯，而数学对于表达能力则有更高的要求，要求叙述简洁、逻辑清晰，因此本教学设计强调学生在有相当阅读量的积累后，通过自主练习，逐渐感受用英语表达数学理论的基本范式. 教师在教学过程中的主要任务在于为学生提供合适的学习资料，在学生学习的过程中给予提示与指导，及时指出学生的问题并予以纠正. 对于语言的学习，阅读量的积累是至关重要的，教师在课堂上的讲解、学生在课堂上的练习，都只是学习的一部分环节，如果需要帮助学生正确掌握表达数学理论的范式，尽量不留死角，就必须保证课前预习和课后复习的有效性，预习复习材料的充足性，这对教师的教学资料的积累和学生自主学习能力，都是一个挑战. 4. 教学支持条件分析 学情条件：初二8班是实验班，学生有较强的学习热情和好奇心，也知道课前预习、课上参与学习活动、课后复习的重要性，在曾经的数学课程教学中，也有一定的课前预习，课堂讨论的传统，对于本教学设计的各个环节，是可以理解教师的用意，并遵循教师的指导进行学习活动. 在知识层面上，学生已经系统学习过一次函数相关的知识，课程中提供的学习资料都是学生熟悉的数学知识；学生在英语学习上，已经有多年的积累，对于英语语法的学

大学英语精读课文翻译
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
