数学专业英语 第2章课后答案
2.12.比:ratio 比例:proportion 利率:interest rate 速率:speed 除:divide 除法:division 商:quotient 同类量:like quantity 项:term 线段:line segment 角:angle 长度:length 宽:width高度:height 维数:dimension 单位:unit 分数:fraction 百分数:percentage3.(1)一条线段和一个角的比没有意义,他们不是相同类型的量.(2)比较式通过说明一个量是另一个量的多少倍做出的,并且这两个量必须依据相同的单位.(5)为了解一个方程,我们必须移项,直到未知项独自处在方程的一边,这样就可以使它等于另一边的某量.4.(1)Measuring the length of a desk, is actually comparing the length of the desk to that of a ruler.(3)Ratio is different from the measurement, it has no units. The ratio of the length and the width of the same book does not vary when the measurement unit changes.(5)60 percent of students in a school are female students, which mean that 60 students out of every 100 students are female students.2.22.初等几何:elementary geometry 三角学:trigonometry 余弦定理:Law of cosines 勾股定理/毕达哥拉斯定理:Gou-Gu theorem/Pythagoras theorem 角:angle 锐角:acute angle 直角:right angle 同终边的角:conterminal angles 仰角:angle of elevation 俯角:angle of depression 全等:congruence 夹角:included angle 三角形:triangle 三角函数:trigonometric function直角边:leg 斜边:hypotenuse 对边:opposite side 临边:adjacent side 始边:initial side 解三角形:solve a triangle 互相依赖:mutually dependent 表示成:be denoted as 定义为:be defined as3.(1)Trigonometric function of the acute angle shows the mutually dependent relations between each sides and acute angle of the right triangle.(3)If two sides and the included angle of an oblique triangle areknown, then the unknown sides and angles can be found by using the law of cosines.(5)Knowing the length of two sides and the measure of the included angle can determine the shape and size of the triangle. In other words, the two triangles made by these data are congruent.4.(1)如果一个角的顶点在一个笛卡尔坐标系的原点并且它的始边沿着x轴正方向，这个角被称为处于标准位置.(3)仰角和俯角是以一条以水平线为参考位置来测量的,如果正被观测的物体在观测者的上方,那么由水平线和视线所形成的角叫做仰角.如果正被观测的物体在观测者的下方,那么由水平线和视线所形成的的角叫做俯角.(5)如果我们知道一个三角形的两条边的长度和对着其中一条边的角度,我们如何解这个三角形呢?这个问题有一点困难来回答,因为所给的信息可能确定两个三角形,一个三角形或者一个也确定不了.2.32.素数:prime 合数:composite 质因数:prime factor/prime divisor 公倍数:common multiple 正素因子: positive prime divisor 除法算式:division equation 最大公因数:greatest common divisor(G.C.D) 最小公倍数: lowest common multiple(L.C.M) 整除:divide by 整除性:divisibility 过程:process 证明:proof 分类:classification 剩余:remainder辗转相除法:Euclidean algorithm 有限集:finite set 无限的:infinitely 可数的countable 终止:terminate 与矛盾:contrary to3.(1)We need to study by which integers an integer is divisible, that is , what factor it has. Specially, it is sometime required that an integer is expressed as the product of its prime factors.(3)The number 1 is neither a prime nor a composite number;A composite number in addition to being divisible by 1 and itself, can also be divisible by some prime number.(5)The number of the primes bounded above by any given finite integer N can be found by using the method of the sieve Eratosthenes.4.(1)数论中一个重要的问题是哥德巴赫猜想,它是关于偶数作为两个奇素数和的表示.(3)一个数,形如2p-1的素数被称为梅森素数.求出5个这样的数.(5)任意给定的整数m和素数p,p的仅有的正因子是p和1,因此仅有的可能的p和m的正公因子是p和1.因此,我们有结论:如果p是一个素数,m是任意整数,那么p整除m,要么(p,m)=1.2.42.集:set 子集:subset 真子集:proper subset 全集:universe 补集:complement 抽象集:abstract set 并集:union 交集:intersection 元素:element/member 组成:comprise/constitute包含:contain 术语:terminology 概念:concept 上有界:bounded above 上界:upper bound 最小的上界:least upper bound 完备性公理:completeness axiom3.(1)Set theory has become one of the common theoretical foundation and the important tools in many branches of mathematics.(3)Set S itself is the improper subset of S; if set T is a subset of S but not S, then T is called a proper subset of S.(5)The subset T of set S can often be denoted by {x}, that is, T consists of those elements x for which P(x) holds.(7)This example makes the following question become clear, that is, why may two straight lines in the space neither intersect nor parallel.4.(1)设N是所有自然数的集合,如果S是所有偶数的集合,那么它在N中的补集是所有奇数的集合.(3)一个非空集合S称为由上界的,如果存在一个数c具有属性:x<=c对于所有S中的x.这样一个数字c被称为S的上界.(5)从任意两个对象x和y，我们可以形成序列（x，y），它被称为一个有序对，除非x=y，否则它当然不同于（y，x）.如果S和T是任意集合，我们用S*T表示所有有序对（x,y),其中x术语S，y属于T.在R.笛卡尔展示了如何通过实轴和它自己的笛卡尔积来描述平面的点之后，集合S*T被称为S和T的笛卡尔积.2.52.竖直线:vertical line 水平线:horizontal line 数对:pairs of numbers 有序对:ordered pairs 纵坐标:ordinate 横坐标:abscissas 一一对应:one-to-one 对应点:corresponding points圆锥曲线:conic sections 非空图形:non vacuous graph 直立圆锥:right circular cone 定值角:constant angle 母线:generating line 双曲线:hyperbola 抛物线:parabola 椭圆:ellipse退化的:degenerate 非退化的:nondegenerate任意的:arbitrarily 相容的:consistent 在几何上:geometrically 二次方程:quadratic equation 判别式:discriminant 行列式:determinant3.(1)In the planar rectangular coordinate system, one can set up aone-to-one correspondence between points and ordered pairs of numbers and also a one-to-one correspondence between conic sections and quadratic equation.(3)The symbol can be used to denote the set of ordered pairs（x，y）such that the ordinate is equal to the cube of the abscissa.（5）According to the values of the discriminate，the non-degenerate graph of Equation （iii） maybe known to be a parabola， a hyperbolaor an ellipse.4.（1）在例1，我们既用了图形，也用了代数的代入法解一个方程组（其中一个方程式二次的，另一个是线性的）。

gasoline-powered car in Germany.In the following year,the milestone vehicle was built by Gottlieb Daimler，another German.He perfected the two-cylinder gasoline engine and attached it to the stagecoach,thereby producing the first four-wheeled motor vehicle in the world．2Why did Henry Ford produce automobiles on a moving conveyor line?Answer：In1913,Henry Ford began making automobiles on a moving conveyor line in his factories.He realized that efficient mass production could lower ear prices,making cars affordable for the average person，thus generating a huge market．This was a smashing success.By1916 annual U S auto production reached one million units,a level not reached by any other country until about40years later in England.3What's the function of engine?Answer：The engine acts as the power unit.4What's the function of ignition plug?Answer：The ignition plug supplies the electric spark to ignite the air—fuel mixture in the cylinders.5Why do we need the cooling system on engine?Answer：The cooling system removes excessive heat from the engine.The temperature in engine combustion chambers is about2,000o F(1,094℃).Since steel melts at round2,500o F(1,354℃), this heat must be carried away to prevent engine damage.Air and coolant are used to carry away the heat.6What's the function of storage battery?Answer：The battery stores electricity.It supplies electricity for the ignition,horn,lights,heat and stater.The alternator changes the engine's mechanical energy into electrical energy and recharges the battery.7What do dimensions of all automobile include?Answer：The dimensions of an automobile can make you know the appearance of it．They contain the wheelbase,the track front and rear,the overall length,the overall width,he overall height，overhang front,overhang real,the angle of approach,the angle of departure,interior length, interior width，interior height，the ground clearance，curb weight，gross vehicle weight，number of the doors，seating capacity and trunk or cargo space．8Describe the definition of compression ratio.Answer：Compression ratio are frequently used engine pression ratio compares the total cylinder volume to compression chamber volume.9Please list the name of the four strokes，and explain the working principle of the four strokecycle.Answer：The four strokes refer to intake，compression，combustion(power)and exhaust strokes that occur during two crankshaft rotations per working cycle of the gasoline engine and diesel engine.The cycle begins at top dead center(TDC)，when the piston is farthest away from the axis of the crankshaft On the intake stroke of the piston，the piston descends from the top of the cylinder，reducing the pressure inside the cylinder．A mixture of fuel and air is forced(by atmospheric or greater pressure)into the cylinder through the intake(inlet)port.The intake(inlet) valve(or valves)then close(s)，and the compression stroke compresses the fuel-air mixture.The air-fuel mixture is then ignited near the end of the compression stroke，usually by a spark plug(for a gasoline or Otto cycle engine)or by the heat and pressure of compression(for a Diesel cycle or compression ignition engine)The resulting pressure of burning fuel gas pushes the piston through the power stroke In the exhaust stroke,the piston pushes the products of combustion from the cylinder through an exhaust valve or valves.10How many parts does the chassis consist of?Answer：In the case of a vehicle，the chassis includes four parts：transmission system，driving system，steering system and braking system.11Please write down every part function of the chassis.Answer：The function of the transmission is to transmit the power and torque from the engine to the wheels.The driving system carries the power from the transmission to the differential at the real-wheel axles，causing the rear wheels to rotate.The purpose of the steering system is guiding the car where me driver wants it to go.As we know,the brake system is used to slow down and stop a vehicle.12Please give examples of several forms and features of body.Answer：(1)4x4or4WD(“four by four”or“four wheel drive”)Vehicle：A four-wheeled vehicle with a drivetrain that allows all four wheels to receive power from the engine simultaneously The terms are usually(but not exclusively)used in Europe to describe what is referred to in North America as a sport utility vehicle or SUV f see below).(2)Convertible Vehicle:A body style with a flexible textile folding roof or rigid retracting roof of highly variable design detail to allow driving in open or enclosed modes.(3)Crossover(or CUV)Vehicle:A loose marketing term to describe a vehicle that blends features of a SUV with features of a car especially forgoing the body on frame construction of the SUV in favor of the car’s unibody or monocoque construction.(4) MPV:Multi-purpose vehicle a large car or small bus is designed to be used on and off road and easily convertible to facilitate loading of goods from facilitating carrying people.(5)Pickup Truck:A small，medium，or large-sized truck，though smaller in every case than a Semi tractor truck.The passenger cabin is wholly separated from the cargo bed.(6)Roadster:Originally a two-seat open car with minimal weather protection——without top or side glass though possibly with optional hard or soft top and side curtains(i.e.，without roll—up glass windows).In modem usage，the term means simply a two—seat sports calf convertible，a variation of spyder.13Please write the types of car lights and the roles of the lights.Answer：The lighting system in a typical automobile includes the headlights，parking lights，direction signal lights，side marker lights，stoplights，backup lights，tail lights and the interior lights The interior lights include instrument-panel lights，various warning，indicator and courtesy lights which turn on when a car-door is opened.When the light switch is pulled out,the circuit from the battery to the headlights is completed.This switch has two positions,low beam anddriving beam.These are also called passing beam and high beam.The backup lights come on when the driver shifts into reverse.This closes a switch linked to the selector lever which connects the backup lights to the battery.Blinker lights are installed on many cars to provide a means of signaling when a car is smiled on the highway or has pulled off to the side.The blinking is much mom noticeable than a steady light and provides a warning to approaching ears.14Please list the main categories of the sensors used in the engine electronic control system. Answer：The main categories of the sensors used in the engine electronic control system include AFM，CTS，CMPS，CKPS，TPS，O2S，A／F ratio sensor and KS.15How to operate the EFI system?Answer：The EFI system uses various sensors to detect the engine conditions and automobile running conditions.And the engine ECU calculates the optimum fuel injection volume,and causes the injectors to inject the fuel.16Please list the basic types of automatic transmissions.Answer：There are two basic types of automatic transmissions based on whether the vehicle is rear wheel drive or front wheel drive.On a rear wheel drive car,the transmission is usually mounted to the back of the engine.A drive shaft connects the rear of the transmission to the final drive．which is located in the rear axle and is used to send power to the rear wheels.On a front wheel drive car, the transmission is usually combined with the final drive to from what is called a transaxle.17What are the main components that make up an automatic transmission?Answer：The main components that make up an automatic transmission1nclude:(1)Planetary gear sets which are the mechanical system provide the various forward gear ratios as well as reverse.(2)The hydraulic system uses a special transmission fluid sent under pressure by an oil Dump through the vane body to control the clutches and the bands in order to control the planetary gear sets.(3)Seals and gaskets an used to keep the oil where it is supposed to be and prevent it from leaking out．(4)The torque convener acts like a clutch to allow the vehicle to come to a stop in gear while the engine is soil running.(5)The governor and the modulator or throttle cable monitor speed and throttle position in order to determine when to shift.(6)On newer vehicles．shift points are controlled by computer which directs electrical solenoids to shift oil flow to the appropriate component at the right instant.18Please list the four steps of ABS control cycle.Answer：The four steps of ABS control cycle：(1)EBCM monitoring the wheel speed.(2)Isolating the wheel circuit if the wheel is decelerating too fast(pressure maintain).(3)Reducing wheel circuit pressure if the wheel continues to decelerate too fast.(4)Increasing the wheel circuit pressure when wheel acceleration reaches a preset level.19What is the function of ABS?Answer：An anti-lock brake system(ABS)is a computer-controlled brake system that helps prevent wheels lockup during braking.ABS can maintain control of the vehicle to stop vehicle in the shortest possible distance and in as straight a line as possible，the wheels must be prevented from locking.20Please list the functions of the cruise system.Answer：The cruise control system(CCS)allows you to maintain a set speed above40km/h without keeping your foot off the accelerator pedal.21What is ACC?Answer：Adaptive cruise control(ACC)is an automotive feature that allows a vehicle’s cruisecontrol system to adapt the vehicle's speed to the traffic environment.22Why does the automobile require regular attention and preventive maintenance?Answer：Most of the major parts and systems of the chassis body and engine have predictable use. These parts and systems require regular attention and preventive maintenance.Regular,scheduled maintenance can prevent most common problems and as sure that your car take corrective action. Preventive maintenance will reduce the chance of breakdowns and lower your overall costs.23If a Toyota saloon car’s accelerating capability at high vehicle speed was poor，what will you do?Answer：If a Toyota saloon car’s accelerating capability at high vehicle speed was poor，I shall do as follows:(1)Checking the symptom：(for example)There was a Toyota saloon car，its engine type was2JZ —GE Its accelerating capability at high vehicle speed was poor.(2)Reporting undergoing:(for example)According to what the driver said,firstly gave a drive test which confirmed the driver's description that during acceleration,the output power of the engine is insufficient，likely caused by poor fuel supply So we had a fuel pressure test for the still vehicle The pressure at idle speed was25kg／cm2，and35kg／cm2at acceleration.That was normal Then we checked the sparking timing The result was ing the hand—held tester specifically for Toyota to read trouble codes，we found no trouble codes At last we checked the dynamic data steam.The result was within the accepted range At this time．a11of us were confused，but after consulting with other staff，we were still suspicious of the fuel supply So we linked a fuel-pressure gauge to the fuel rail again and drove the car to have a road test During acceleration，we found that the gauge arm dropped a little.After coming back，we disassembled the fuel pump from the fuel tank and found that the screen was seriously clogged At last，we talked with the driver knowing that his car has run for more than200,000km without any services for the fuel tank.(3)Trouble Solving：(for example)Cleaned the screen and changed the fuel filter The vehicle’s acceleration became satisfied.24What can the screwdriver do?Answer：The screwdriver is a device specifically designed to insert and tighten，or to loosen and remove screws The screwdriver is made up of a head or tip,which engages with a screw,a mechanism to apply torque by rotating the tip,and some way to position and support the screwdriver.25For testing the mechanical side of the engine，you will need some more specialized equipment. Please take some examplesAnswer：For testing the mechanical side of the engine,we need some more specialized equipment.A vacuum gauge with several adapters can be used to test manifold vacuum and test vacuum operated circuits.A vacuum pump is handy for testing vacuum operated components such as EGR valves and heating and air conditioning systems.26How to do the effective diagnosis and troubleshooting when the car breakdown?Answer：The secret of effective diagnosis and troubleshooting is to have a logical well-ordered procedure.Following a logical step-by-step procedure will get you to the root cause of a problem quickly and efficiently.27What can the wrench do?Answer：A wrench or spanner is a tool used to provide a mechanical advantage in applying torque to turn bolts,nuts or other items designed to interface with a wrench.At present，we can see thosetools，like box wrench，electronic torque wrench，combination wrench，adjustable wrench，speed handle and ratchet handle.28What can the diagnostic tree do?Answer：The diagnostic tree goes in a logical progression.It will ask a question，usually yes or no，and depending on the answer will branch off in two or more directions.The last box in the tree will have the problem and how to correct it.A more complicated procedure will have branches going into specific tests and then have two or more branches from there depending on test results. 29How to check the engine oil level?Answer：Check the oil gauge.If under the low level,add the proper oil in the engine.Or dim the dim-stick through the hole in the engine,check the dimmed line.If need,add the proper oil.。
