This step is performed by a sample and hold circuit, which samples at regular intervals called . The length of the sampling interval is the same as the sampling period , and the reciprocal of the is the sampling frequency f s. According to the Nyquist theorem, a signal with a maximum frequency of W Hz (called a band-limited signal) must be at least 2W samples per second to ensure accurate recording. When this minimum is not respected, called aliasing occurs.R ①sampling intervals ②distortion ③conversion ④sampling period ⑤sampled四、Comprehension. choose the best answer according to this passage.Previously in this chapter, we’ve discussed how data elements (characters, fields, and records) c an be organized in files. In file-oriented systems, each file is independent and contains all the information necessary to process the records in that file. In a database, the data is organized in multiple related files. Because these files are related, us er can access data in multiple files at one time. A database management system (DBMS) is the software that allows the user to create, maintain, and report the data and file relationships. By contrast, a file management system is software that allows the user to create, maintain, and access one file at a time.There are problems with traditional data management. Many result from viewing applications independently. For example, consider payroll. Most organizations prepare their payrolls by computer because using a machine instead of a small army of clerks saves money. Thus, the firm develops a payroll program to process a payroll file. Inventory, accounts receivable, accounts payable, and general ledger analysis are similar applications, so the firm develops program, and inventory file, an accounts receivable program, an accounts receivable file, and so on. Each program is independent, and each processes its own independent data file.The solution to these problems is often organizing the data as a single, integrated database.How does the use of a centralized database solve the data redundancy problem? All data are collected and stored in a single place; consequently, there is one and only one copy of any given data element. When the value of an element (an address, for example) changes, the single database copy is corrected. Any program requiring access to this data element gets the same value, because there is only one value.1.In file-oriented systems, each file is independent and contains all the information necessary to processthe in that file.A. elementsB. recordsC. dataD. software2. A database management system (DBMS) is the software that allows the user to create, maintain, and reportthe and file relationships.A. softwareB. elementsC. dataD. records3. The firm develops an inventory program to process .A. data fileB. an accounts receivable fileC. a payroll fileD. an inventory file4.The solution to these problems is .A. changing the programB. using a machine instead of a small army of clerksC. often organizing the data as a single, integrated database.D. having such items in one instead of many locations5. Any program requiring access to this data element gets the same , because there is only onevalue.A. programB. valueC. dataD. copy五、T ell whether the following statements are true(T) or false(F) according to the passageHow should you think of the laser? Think of it simply as a tool. One that uses light instead of mechanical energy. And a tool that allows its user to control the form and amount of energy directed at a particular place. The laser can cut through a two-inch-thick sheet of steel or detect a single atom. It can perform a task as dramatic as igniting a thermonuclear fusion reaction or as seemingly mundane as drilling a hole in a baby-bottle nipple.A laser is a device that produces a very special kind of light. Y ou can think of it as a super flashlight. But the beam that comes out of a laser differs from the light that comes out of a flashlight in four basic ways: Laser light is intense. Y et only a few lasers are powerful. That’s not the contradiction you might think.. Intensity is a measure of power per unit area, and even a laser that emits only a few milli-watts can produce a lot of intensity in a beam that’s only a millimeter in diameter.Laser beams are narrow and will not spread out like ordinary light beams. This quality is called directionality.Laser light is coherent. This means that all the light waves coming out of a laser are lined up with each other.Lasers produce light of only one color. Or, to say it in a more technical way, the light is monochromatic. Ordinary light combines all the colors of visible light (i.e., the spectrum). Mixed together, they come out white. Laser beams have been produced in every color of the rainbow (red is the most common laser color), as well as in many kinds of invisible light, but each laser can emit one color and one color only.1. The laser can cut through a two-inch-thick sheet of steel or detect a single atom.()2. The flashlight can perform a task as seemingly mundane as drilling a hole in a baby-bottle nipple.()3. All the light waves coming out of a flashlight are lined up with each other.()4. Laser beams are narrow and will not spread out like ordinary light beams.()5. Ordinary light combines all the colors of visible light . ()六、T ranslate the following sentences into Chinese.1.The low pass filter, called the anti-aliasing filter, removes all frequencies above half the selected sampling rate.2. The A/D converter chooses a quantization level for each analog sample. An N-bit converter chooses among 2N possible quantization levels. The larger the number of levels, the smaller the quantization errors, calculated as the difference between the quantized level and the true sample level.3. Once digital signal processing is complete, digital-to-analog (D/A) conversion must occur. This process begins by converting each digital code into an analog voltage that is proportional in size to the number represented by the code.4. For example, signals whose frequencies are restricted to a narrow band of high frequencies can be sampled ata rate similar to twice the width of the band instead of twice the maximum frequency.5. The images of each frequency f present in a sampled signal appear, through sampling, at the infinite number of frequencies kf s±f Hz.6. After a brief acquisition time, during which a sample is acquired, the sample and hold circuit holds the sample steady for the remainder of the sampling interval. This hold time is needed to allow time for an A/D converter to generate a digital code that best corresponds to the analog sample.答案一、1. spectrum 2. laser beam 3. thermonuclear4.digital-to-analog (D/A) conversion5. database6. extraterrestrialImpediment 8. compatibility 9. Premonition 10. asunder11、digital signal processor 12、Consistency 13. baseband14. Monochromatic 15.

question.(1)Greenspace facilities are contributing to an important extent to the quality of the urban environment.Fortunately it is no longer necessary that every lecture or every book about this subject has to start with the proof of this idea.At present it is generally accepted,although more as self-evident statement than on the base of a closely-reasoned scientific proof.The recognition of the importance of greenspaces in the urban environment is a first step on the right way,this does not mean,however,that sufficient details are known about the functions of greenspace in towns and about the way in which the inhabitants are using these spaces.As to this rather complex subject I shall,within the scope of this lecture,enter into one aspect only namely the recreative function of greenspace facilities.The theoretical separation of living,working,traffic and recreation which for many years has been used in town-and-country planning,has in my opinion resulted in disproportionate attention for forms of recreation far from home,whereas there was relatively little attention for improvement of recreative possibilities in the direct neighborhood of the home.We have come to the conclusion that this is not right,because an important part of the time which we do not pass in sleeping or working,is used for activities at and around home.So it is obvious that recreation in the open air has to begin at the street-door of the house.The urban environment has to offer as many recreation activities as possible,and the design of these has to be such that more obligatory activities can also have a recreative aspect.The very best standard of living is nothing if it is not possible to take a pleasant walk in the district,if the children cannot be allowed to play in the streets,because the risks of traffic are too great,if during shopping you can nowhere find a spot for enjoying for a moment the nice weather,in short,if you only feel yourself at home after the street-door of your house is closed afteryou.31.According to the author,the importance of greenspaces in the urban environment _______.A. is still unknownB. is usually neglectedC. is being closely studiedD. has been fully recognized32.The theoretic separation of living,working,traffic and recreation has led to _______.A. the disproportion of recreation facilities in the neighborhoodB. the location of recreation facilities far from homeC. relatively little attention for recreative possibilitiesD. the improvement of recreative possibilities in the neighborhood33.The author suggests that the recreative possibilities of greenspace should be provided _______.A. in special areasB. in the suburbsC. in the neighborhood of the houseD. in gardens and parks34.According to the author,greenspace facilities should be designed in such a way that _______.A. more obligatory activities might take on a recreation aspect.B. more and more people might have access to themC. an increasing number of recreative activities might be developedD. recreative activities might be brought into our homes35.The main idea of the passage is that _______.A. better use of greenspace facilities should be made so as to improve the quality of our lifeB. attention must be directed to the improvement of recreative possibilitiesC. the urban environment is providing more recreation activities than it did many years agoD. priority must be given to the development of obligatory activities(2)The actual work of cleaning and caring for the guest room is performed by the room attendants.Their duties include recognizing the guests,introducing room facilities and service,making or changing beds,dusting furniture,sweeping or cleaning floors and carpets,washing bathrooms,replacing towels and washing clothes,making up room and doing turn-down service.They should also supply any personal service to satisfy the guests' reasonable demands,such as wake-up service,room service,laundry service,shoeshine service and baby-sitting service.Whenever and wherever possible,the staff should offer to do extra things for the guests.In addition,they are expected to check up rooms and report any signs of damage or wear and tear that may make repairs and maintenance necessary.Finally,to be competent hotel staffs,they should be capable of handling with unexpected emergency and try to minimize the damage or negative influence.Room attendants have an intimate contact with the guests.A guest may ask the attendants to make up his room at a certain time,or he may indicate he does not want to be disturbed at all,or he would like to have meals in his room.Almost all hotels provide signs that the guest can hang on the doorknob in either of these cases.In addition,guests frequently ask room attendant for items that are supplied by the housekeeping department,such as irons,transformers,special pillows,extra hangers,cribs for infants and hair dryers.In some hotels,the room attendants pick up and deliver clothing for the laundry and valet service.Heavier chores are performed by men who are usually called housemen.Their work involveswindow-washing,shampooing carpets,polishing metals,removing and cleaning draperies,cleaning the public areas of the hotels,and many other tasks that might be beyond the physical capacities of women.The housemen also run errands for thehousekeeping department,such as providing guests with extra things on request.36.heavy chores are performed by _______.A. housekeepersB. housemenC. room attendantsD. assistants37.The word “intimate" in the first line of the second paragraph means _______.A. close and familiarB. clearC. internalD. interesting38.The word “crib" in the phrase “cribs for infants" means _______.A. copyB. boneC. foodsD. a bed for new baby39.From this passage we can know that _______.A. room attendants work very hard .B. room attendants are very kindC. room attendants are the busiestD. room attendants' work are very important40.Housemen do the following except _______.A. washing windowB. serving foodsC. running errands for the housekeeping departmentD. cleaning draperies(3)We can make mistakes at any age. Some mistakes we make are about money. But most mistakes are about people. “Did Jerry really care when I broke up with Helen?” “When I got that great job, did Jim really feel good about it, as a friend? Or did he envy my luck?”“And Paul-why didn't I pick up that he was friendly just because I had a car?” When we look back, doubts like these can make us feel bad. But when we look back, it's too late.Why do we go wrong about our friends——or our enemies? Sometimes what people say hides their real meaning. And if we don't really listen, we miss the feeling behind the words. Suppose someone tells you, “You're a lucky dog.” Is he really on your side? If he said, “You're a lucky guy” or “You're a lucky gal,” that's being friendly. But “lucky dog”? There's a bit of envy in those words. Maybe he doesn't see it himself. But bringing in the “dog” bit puts you down a little. What he may be saying is that he doesn't think you deserve your luck.“Just think of all the things you have to be thankful for” is another noise that says one thing and means another. It could mean that the speaker is trying to get you to see your problem as part of your life as a whole. But is he? Wrapped up in this phrase is the thought that your problem isn't important. It's telling you to think of all the starving people in the world when you haven't got a date for Saturday night.How can you tell the real meaning behind someone's words? One way is to take a good look at the person talking. Do his words fit the way he looks? Does what he says quare with(符合) the tone of voice? His posture? The look in his eyes? Stop and think. The minute you spend thinking about the real meaning of what people say to you may save another mistake.41. In the first paragraph, the writer recalls some things that happened between him and his friends. He ________.A. feels happy, thinking of how nice his friends were to himB. feels he may not have “read” his friends' true feeling correctlyC. is sorry that his friends let him downD. thinks it was a mistake to have broken up with his girl friends, Helen42. In the second paragraph, the writer talks about someone saying, “You're a lucky dog.” He is saying that ________.A. the speaker of this sentence is just being friendlyB. this saying means the same as “You're a lucky guy” or “You're a lucky gal.”C. the word “dog” shouldn't be used to apply to peopleD. sometimes the words give a clue (线索) to the feeling behind the words43. This passage tries to tell you how to ________.A. avoid mistakes about money and friendsB. “size up” peopleC. avoid mistakes in understanding what people tell youD. keep people friendly without trusting them44. In listening to a person the important thing is ________.A. to notice his tone, his posture, and the look in his eyeB. to listen to how he pronounces his wordsC. to check his words against his manner, his tone of voice, and his postureD. not to believe what he says45.

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 parts2.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 preservationfor 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, etc3.How are metal alloys made by the casting process? (b) Distinguish between wrought alloy products and cast alloy products.金属铸造合金的过程是怎样的?区分可锻合金产品和铸造合金产品。

The program may however also be designed to have other effects on the systems it infects, ranging from the annoying to the disastrous.Virus attacks are growing rapidly these days・ According to BusinessWeek, the 76,404 attacks reported in the first half of 2003 nearly match previous year's total number. As new antivirus tools are more powerful than before, the virus writers are getting a lot smarter with newer and creative ways to attack network systems. Let's first examine some common virus types: Basic Virus - a piece of software code that is developed to attack computers and network systems via email or Internet connections. It quickly replicates itself andgradually attaches to files, programs or the hard drive.Trojan Horses - This is a program that doesn't replicate when entering a system but can be effectively used to open 'back doors.1 Trojan Horses allow hackers to take controlover a particular system or to steal very important data.Worm ・ this type of virus is able to spread itself automatically over the network from one computer to the next. During a worm attack, users1 computers get infected withouteven having to click open email attachment or any program, etc.Since it is very difficult to avoid the virus, your best defense is a powerful antivirus program. In order to fight with such viruses, the software vendors should focus on makingtheir products more robust. This may ask for a trade-off between user-friendliness andsecurity. In specific cases it may require line-by-line inspection, code retooling and evensystems automation to defend the installed programs.(一choose the best answer according to the passage A•(根据上文的内容选择正确的答案。

Another stagnation point exists at “B," where the two airstreams rejoin and resume at identical velocities. When viewed from the side, an up wash is created ahead of the airfoil and a downwash at the rear. In the case of Figure 1-4, the highest velocity is at the top of the airfoil, and the lowest velocity at the bottom. Because these velocities are associated with an object (in this case, an airfoil), they are called local velocities as they do not exist outside the lift-producing system. This concept can be readily applied to a wing or other lifting surface. Because there is a difference of velocity above and below the wing, the result is a higher pressure below the wing and a lower pressure above the wing. This pressure difference produces an upward force known as the Magnus Effect, the physical phenomenon whereby an object's rotation affects its path through a fluid.翻译:如图1-4所示,在A点,这里有个停滞点,气流在这里撞上机翼的前表面并分开;一些空气向上,一些空气向下。

Forces having such a property are called conservative.2、A combination of bodies that are stationary relative to one another with respect to whichmotion is being considered an a timepiece indicating the time forms a reference frame.3、The concepts of an equilibrium, state and a reversible process play a great part inthermodynamics. All the quantitative conclusions of thennodynamics are strictly applicable(适用)only to equilibrium states and reversible processes.4、If a gas is in equilibrium, its molecules move absolutely without order, chaotically. All thedirections of motion are equally probable, and none of them can be given preference over others.5> Huygens' principle: The theory by which light waves spreading out from a point source can beregarded as the superposition of tiny secondary wavelets.6> If we imagine a separate isolated body in a space where no other bodies are present, then wecan not speak of the motion of the body because there is nothing with respect to which the body could change its position.7、A combination of bodies that are stationary relative to one another with respect to whichmotion is being considered and a timepiece indicate the time forms a reference fram.8、Translational motion is defined as motion in which any straight line associated with themoving body remains parallel to itself.9N Dynamics studies the motion of bodies with a view to what causes this motion to have the nature it does, i.e. with a view to the interactions between bodies.10,Vectors are defined as quantities characterized by a numerical value and a direction and, also, as ones that are added according to the triangle or parallelogram method.11,We shall define internal forces as the forces with which given body is acted upon by the other bodies of the system and external forces as those produced by the action of bodies not belong to the system.12,For a conservative force, the work done on a particle by the force may depend only on the initial and final positions of the particle and not on the path along which the particle moved,. 13,Conservative forces can be defined in two ways:(l)as forces whose work does not depend on the path along which a particle passes from one point to the another, and(2) as forces whose work along any closed path equals zero.14,We can thus use the function E/f to determine the work done on a particle by conservative forces along any path beginning at arbitrary point 1 and terminating at arbitrary point 2 .15,Assuming that the reference frame relative to which we are considering the complex motion of a rigid body is stationary, the motion of the body can be represented as rotation with the angular velocity coin a reference frame moving translationally with the velocity v0 relative to the stationary frame.16,All the quantitative conclusions of the thermodynamics are strictly applicable only to equilibrium states and reversible processes.17,The absolute temperature is proportional to the mean kinetic energy of translational motion of the molecules of a substance.18,The heat capacity of a body is defined as the quantity equal to the amount of heat that must be imparted to the body to raise its temperature by one Kelvin.19,Temperature: A measure of the average kinetic energy per molecule in a substance, measure in desrees Celsius or Fahrenheit or in Kelvin..20,Absolute zero: the lowest possible temperature that a substance may have- the temperature at which molecules of a substance have their minimum kinetic energy.21,Multiplication theorem of probabilities: the probability of the simultaneous occurrence of statistically independent events equals the product of the probabilities of each of themoccurring separately.22,Entropy: a measure of the disorder of a system. Whenever energy freely transforms from one form to the another, the direction of transformation is toward a state of greater disorder and therefore toward one of greater entropy.23,By coherence is meant the coordinated proceeding of several oscillatory or wave processes. 24,The superposition of waves producing regions of reinforcement and regions of cancellation.Constructive interference refers to regions of reinforcement; destructive interference refers to regions of cancellation.25,There is no appreciable physical difference between interference and diffraction. Both phenomena consist in the redistribution of the light flux as a result of superposition of the waves.干涉和衍射没有明显的区别26,Like charges repel each other, unlike charges attract each other.同种电荷相互排斥,异种电荷相互吸引27,The arrangement of the charges setting up the field being studied may change under the action of the test charse.。
