Even the cleverest animals cannot do things which to us seem very 2 and which small children, as soon as they learn to talk, would be able to do.A German scientist, who 3 experiments for many years with big apes(猿), found that his apes could use his sticks(棍) as tools to pull down bananas which they could not 4 . But they only used the stick to get a banana when both the banana and the stick were in view at the same time. If the banana was in front of them and the stick was behind them, they could not use the stick. They could not keep the banana 5 enough in mind to look around and then pick up the stick and use it.The 6 for this is clear. We have words for banana and stick which help use to think about these things when they are not in 7 . Even a small child knowing the words "banana" and "stick" has an idea of their relationship and is able to think "stick" together with "banana" and to remember this long enough to pick the stick 8 behind and use it on the banana.9 to speak, animals cannot keep their knowledge of things for long. That is why they often interrupt one line of action to do something else and later forget it completely. Human beings, on the other hand, use 10 and are able to do one thing continuously.1．A）that B）this C）way D）eat2．A）honest B）foolish C）simple D）evident3．A）carried B）dealt C）developed D）performed4．A）get B）reach C）eat D）take5．A）clear B）alive C）long D）complete6．A）answer B）truth C）reason D）cause7．A）vision B）mind C）thought D）sight8．A）from B）in C）at D）around9．A）incapable B）unable C）unwilling D）hard10．A）knowledge B）language C）expressions D）mindACDBC CDABB(3)It is not surprising that people 1 ever associate Britain with wine and ill fact it may astonish you to learn that grapes are grown in the open air in England and nearly 200,000 2 were sold in 1975. There is nothing very new in growing grapes in Britain, 3 the climate. The Romans planted the first vines about AD 300 and 4 a long time people always drank home-produced wines. What destroyed the English wine industry was not5 a change in the climate as the fact that an English King, Henry II, inherited the Bordeaux area of France as part of his dominions6the twelfth century and the imported wine provided7 of competition. The English wine industry did not disappear, however,8the sixteenth century, when the monks, who had been the main producers in the meantime, had their estates taken away by Henry VIII. The new owners let the vineyards die out. But now English people, probably9their memories of holidays by the Mediterranean, drink more wine than ever and the new industry is now developing 10a modest but consistent rate.1．A）hardly B）almost C）nearly D）seldom2．A）bottles of wine B）bottles of wines C）wine bottles D）of wine bottles 3．A）although B）whatever C）in spite of D）however4．A）during B）from C）since D）for5．A）enough B）such C）too much D）so much6．A）on B）during C）for D）since7．A）much B）many C）a great deal D）a large number8．A）as long as B）as far as C）since D）until9．A）because B）for C）because of D）due10．A）in B）by C）at D）onAACDDBCDCC阅读理解答案:(1)CAA (3)ABC (4)ADB (5)BAC (6)CCAD (7)ABAD1 CAB 2CCDD 3ABC 4 ADB 5 BAC 6BCAD 7ABADPassage 1People over the age of 65 in the U.S.A are called senior citizens. Life for these people is different from that for younger Americans. Most senior citizens retire, or no longer work full time. Also it is unusual for people of this age to live with their children and grandchildren. Grandparents tend to live in their own houses or apartments away from their families.For many senior citizens, the years after 65 are not enjoyable. They feel unproductive when they no longer work. Their lives lose meaning. In addition, they may feel lonely being away from their families and the contacts they had in their work. Moreover, they become more concerned with their health as they grow older. If they live in big cities, they often worry about their safety.Other senior citizens enjoy their lives. They feel free to do things they were not able to do when they were working and raising families. They now have time to enjoy hobbies and sports and travel. They associate with their fellow senior citizens who have common interests and equal free time. Many senior citizens move to retirement communities located in warm climates. Some senior citizens continue to work beyond retirement age. Many find new careers and professional opportunities after they retire.The number of senior citizens in the U.S.A is increasing rapidly because people are living longer than before. The average life span for Americans in now more than 74 years. Because of their larger numbers and more active life styles, senior citizens are gaining social influence in the country both politically and economically. Their concerns are receiving a wider audience than ever before. The time may come when all Americans will look forward to becoming senior citizens.1．Many senior citizen ________.A）are enjoyable B）live together with their familiesC）feel unproductive, lonely and unsafe D）feel safe in big cities 2．Senior citizens are gaining social influence because ________.A）the number of senior citizens is growing and because senior citizens are more activeB）senior citizens have experienceC）their average life span is longerD）they do more work now3．Implied but not stated: ________.A）Most of American senior citizens have lived a lonely and unhappy life. B）They have played an important part in society.C）Like young people, senior citizens can still enjoy everything they like.D）Their average lifespan is becoming longer and longer.Passage 2The Great Fire of London started in the very early hours of 2 September 1666. In four days it destroyed more than three-quarters of the old city, where most of the houses were wooden and close together. One hundred thousand people became homeless, but only a few lost their lives.The fire started on Sunday morning in the house of the King's baker in Pudding Lane. The baker, with his wife and family, was able to get out through a window in the roof. A strong wind blew the fire from the bakery into a small hotel next door. Then it spread quickly into Thames Street. That was the beginning.By eight o'clock three hundred houses were on fire. On Monday nearly a kilometer of the city was burning along the River Thames. Tuesday was the worst day. The fire destroyed many well-known buildings, old St Paul's and the Guildhall among them.Samuel Pepys, the famous writer, wrote about the fire. People threw their things into the river. Many poor people stayed in their houses until the last moment. Birds fell out of the air because of the heat.The fire stopped only when the King finally ordered people to destroy hundreds of buildings in the path of the fire. With nothing left to burn, the fire became weak and finally died out.After the fire, Christopher Wren, the architect, wanted a city with wider streets and fine new houses of stone. In fact, the streets are still narrow; but he did build more than fifty churches, among them new St Paul's.The fire caused great pain and loss, but after it London was a better place: a city for the future and not just of the past.4．The fire began in______.A）a hotel B）the palaceC）Pudding Lane D）Thames Street5．It seems that the writer of the text was most sorry for the fact that______.A）some people lost their lives B）the birds in the sky were killed by the fireC）many famous buildings were destroyed D）the King's bakery wasburned down6．Why did the writer cite Samuel Pepys? ______A）Because Pepys was among those putting out the fireB）Because Pepys also wrote about the fireC）To show that poor people suffered mostD）To give the reader a clearer picture of the fire7．How was the fire put out according to the text? ______.A）The king and his soldiers came to helpB）All the wooden houses in the city were destroyedC）People managed to get enough water from the riverD）Houses standing in the direction of the fire were pulled downPassage 3Music which is original is individual and personal. That is to say, it can be identified as belonging to a particular composer. It has particular qualities, or a style, which are not copied from another. If you can recognize the style of a composer, you will probably be able to tell that a certain composition belongs to him or her even though you have never heard it before. A composer organizes his melodies (旋律) and rhythms and combines sounds to create harmony. He may be capable of thinking up very good, original tunes, yet if tunes are poorly organized, the final result will not be to standard.Good music expresses feelings in a way that is suitable to those feelings. There may be joy, sorrow, fear, love, anger, or whatever. Bad music, on the other hand, may confuse unrelated feelings, it may not express any important feeling at all, or it may exaggerate some feelings and make them vulgar, that is, cheap and ugly.Good music will stand the test of time. It will not go out of fashion but will continue to be enjoyed and respected long after it is first introduced. It will gain a kind of permanent status while bad music will disappear and be forgotten quickly. In pop music, where the general rule seems to be "the newer the better", the test of time is the hardest test of all to pass.1．A piece of original music ______.A）has a personal style B）sounds very familiar to our earsC）is one whose style you cannot recognize D）cannot be recognized as belonging to any composer2．Good music is ______.A）well-organized tunes B）the proper expression of feelingsC）an expression of mixed feelings D）exaggeration of some feelings3．The passage is concerned with ______.A）how to compose music B）how to enjoy musicC）how to judge music D）how to perform musicPassage 4Shopping-bag ladies don't beg publicly, but they do not refuse what is offered. Once a shopping-bag lady appears where you live, it is as hard to pass her by without giving her some money as it is to pay no attention to the collection box in church. And although you may not like it, if she chooses your doorway as her place to sleep in the night, it is as morally hard to turn her away as it is to do with a lost dog.Most shopping-bag ladies seem to be between the ages of 40 and 65. They wear layers of clothes even in summer time, with newspapers filled between the layers as something against bad weather.No one knows how many shopping-bag ladies there are in New York. The number is going up. Some persons and researchers spend a great deal of time taking care of or observing shopping-bag ladies and doing what they can to better the life lady hermits（隐士） who're down.1．Shopping-bag ladies are ______.A）lady beggars B）ladies who sell shopping-bagsC）ladies who make shopping-bags D）Those who go hungry 2．They fill newspapers between the layers of their clothes because ______.A）they are so poor B）they have no place to put themC）they want to hide them D）they have to use them to keep the cold out3．Which of the following statements is NOT true.A）There are more and more shopping-bag ladies in the United States .B）Shopping-bag ladies appear only in New York.C）Some people are helping shopping-bag ladies.D）Some people are engaged in their research on these shopping-bag ladies. Passage 5The Internet will play a central role in conducting international trade beyond the year 2000. The World Trade Centers Association (WTCA) recently announced a plan to assist developing countries develop a capacity for e-commerce and e-business. The spin off from this decision can pay huge dividends to offshore companies that position themselves on-line right now to supply goods and services to the coming global Internet trading market.E-business will help you get set up and operate with a minimum of effort and at reasonable prices.E-business Incorporated works with international companies to set up a web-office, or CyberSuite as its own domain accessible over the Internet via its owndomain name or from the e-business Cyberspace Station.If you are a supplier, your CyberSuite would have a showroom where visitors —especially wholesale importers and distributors — can examine images, drawings or listings of what you have to offer. If you are a buyer, your web-office can include a notice board listing products or services or agreements you are looking for and a bidding gallery where suppliers can post bids and link you to their sites to examine products. Trading partners can make purchases, send invoices, hold business meetings, track shipments, and work out potential trade agreements within the E-business Cyberspace Station. E-business seminars and conferences will introduce new potential trade partners to each other.Orders placed on the site are sent immediately to manufacturers and any suppliers integrated into the trade process. For example, established trading partners might include an importer ordering large shipments from a manufacturer and suppliers of parts or raw materials in other countries. By electronically notifying the whole trade net at the same time, each partner is able to trim supply and demand to "just in time" delivery of goods or services. The savings of doing business this way can be substantial — even without the tax advantages.1．E-business Incorporated can help a company to______.A）set up a web-office free of charge B）build a Cybersuite as its domainC）get its own domain name D）have its web site accessible via its own domain name2．In a Cybersuite, a supplier can ______.A）exhibit its products and services B）find more images and drawingsC）get many lists of products D）bid for a certain product or service3．The passage mainly tells about ______.A）the benefits brought by e-business B）how to do e-commerce via InternetC）a project by WTCA D）how to find trade partners via InternetPassage 6For some time past it has been widely accepted that babies - and other creatures - learn to do things because certain acts lead to "rewards"; and there is no reason to doubt that this is true. But it used also to be widely believed that effective reward, at least in the early stages, had to be directly related to such basic physiological (生理的) "drives" as thirst or hunger. In other words, a baby would learn if he got food or drink of some sort of physical comfort, not otherwise.It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.Papousek began his studies by using milk in the normal way to "reward" thebabies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children's responses in situations where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement "switched on" a display of lights - and indeed that they were capable of learning quite complex turns to bring about this result, for instance, two left or two right, or even to make as many three turns to one side.Papousek's light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lights closely although they would "smile and bubble" when the display came on. Papousek concluded that it was not primarily the sight of the lights which pleased them, it was the success they were achieving in solving the problem, in mastering the skill, and that there exists a fundamental human urge to make sense of the world and bring it under intentional control.4．According to the author, babies learn to do things which ______.A）are directly related to pleasure B）will meet their physical needsC）will bring them a feeling of success D）will satisfy their curiosity 5．Papousek noticed in his studies that a baby ______.A）would make learned responses when it saw the milkB）would carry out learned movements when it had enough to drinkC）would continue the simple movements without being given milkD）would turn its head to right or left when it had enough to drink6．In Papousek's experiment babies make learned movements of the head in order to______.A）have the lights turned on B）be rewarded with milk C）please their parents D）be praised7．The babies would "smile and bubble" at the lights because ______.A）the lights were directly related to some basic "drives"B）the sight of the lights was interestingC）they need not turn back to watch the lightsD）they succeeded in "switching on" the lightsPassage 7The digital revolution, as exemplified by the Internet and electronic commerce, has shaken marketing practices to their core. In a recent paper, Wharton's Jerry Wind, director of the SEI Center for Advanced Studies in Management, and co-author Vijay Mahajan, a marketing professor at the College of Business Administration of the University of Texas at Austin, examine the impact of digital marketing on concepts like pricing, when customers can propose their own prices (), or buyersand sellers can haggle independently in auctions ().The paper provides an overview of some of the emerging realties and new rules of marketing in a digital world, and outlines what the new discipline of marketing may look like in the early part of the new century.To begin with, say the authors, the rapid-fire growth of the Internet is helping to drive changes. "It is not just our computers that are being reprogrammed; it is customers themselves, " says Wind. "These emerging cyber consumers are like an alien race that have landed in the midst of our markets. They have different expectations and different relationships with companies from which they purchase products and services. "For one thing, cyber consumers expect to be able to customize everything —from the products and services they buy and the information they seek, to the price they are willing to pay. And with digital technology opening new channels for gaining information, they are more knowledgeable and demanding than previous consumers.Digital customers can also sort products based on any desired attribute, price, nutritional value, or functionality, and they can easily obtain third-party endorsements and evaluations, tapping the experience of other users. "Companies that cannot meet their demands and expectations will be at a loss, " says Wind.4．The passage was most likely to be taken from ________.A）an overview of a paper B）an introduction to a book C）a book on digital revolution D）a paper discussing digital revolution5．From the third paragraph, we can infer that ________.A）the customers are also reprogrammed by computersB）e-business companies need be more knowledgeable about cyber consumers C）cyber consumers are a group of strange peopleD）cyber consumers came from outer space6．Compared with traditional customers, the emerging cyber consumers ________. A）are more difficult to satisfy B）have less knowledge about businessC）have more problems with prices D）are less willing to buy products and services7．In the last paragraph, what Wind said means ________.A）digital consumers' decision to buy depends largely on others' evaluationB）it will be more and more difficult for companies to earn profit in e-businessC）most of the companies in e-business are at a lossD）companies should try their best to meet the digital consumers' demands and expectations。

In C, a block of code is a logically connected group of program statements that can be treated as a unit. You can create a block of code by placing lines of code between opening and closing curly braces. For example: if(x<10) { printf (“too low, try again”); reset_counter(-1); } The two statements after "if" that are between the curly braces are executed if x is less than 10. These two statements with the braces represent a block of code. They are linked together: one of the statements cannot execute without the other also executing.

There are different high-level programming languages. Fortunately, most of them have many kinds of construct in common and vary only in the way that these must be__________________ . Therefore, first thing to be decided about a task is to choose which programming language is best suited for the job.Passage AThe central processing unit(CUP) is the heart of the computer systems. Among other things, its configuration determines whether a computer is fast or slow in relation to other computers. The CPU is the most complex computer system component, responsible for directing most of the computer system activities based on the instructions provided. As one computer generation has evolved to the next, the physical size of the CPU has often become smaller and smaller, which its speedand capacity have increased tremendously. Indeed, these changes have resulted inmicro-Computers that are small enough to fit on your desk and your lap.The CPU comprise the control unit and the arithmetic/logic unit (ALU).The control unit is responsible for directing and coordinating most of the computer systems activities. It determines the movement of electronic signals between main memory and the arithmetic/logic unit, as well as the control signals between the CPU and input/output devices.The ALU performs all the arithmetic and logical(comparison) functions—that is, it adds, subtracts, multiplies, divides, and does comparison. These comparisons, which are basically “less than”, “greater than”, and “equal to”, can be combined into several common expressions , such as “greater than or equal to”. The objective of most instructions that use comparisons is to determine which instruction should be executed next.(二) Tell whether the following statements are true(T) or false(F) according to the passage A(根据上文的内容判断下列句子的正误)1. With the development of computer, the physical size of the CPU has often become bigger and bigger. ( )2. The movement of electronic signals between main memory and the ALU as well as the control signal between the CPU and input/output devices are controlled by the control unit of the CPU. ( )3.

What is the difference between TCP and UDP?答案: TCP (Transmission Control Protocol) is a connection-oriented protocol, which means it establishes a connection between the sender and receiver before transferring data. It ensures that all packets are received in the correct order and provides error checking. UDP (User Datagram Protocol), on the other hand, is a connectionless protocol that does not establish a direct connection before transmitting data. It does not guarantee packet delivery or order but is faster and more efficient for time-sensitive applications.2. What is the purpose of an operating system?答案: An operating system (OS) is a software that manages computer hardware and software resources and provides common services forcomputer programs. Its primary purpose is to enable the user to interact with the computer and provide a platform for running applications. It manages memory, file systems, input/output devices, and multitasking. The OS also handles system security and resource allocation to ensure optimal performance.4. 解答题请参考下文并给出自己的解答。

Microorganisms have evolved feedback mechanisms, whereby a build-up of one end-product cause a feedback effect on the first enzyme of the branch leading to that product. In addition, mechanisms exist whereby the end-product of a branched pathway causes partial feedback inhibition of the first enzymes of the common sequence so that the flux of substrate passing through this sequence is proportionately reduced. This effect is achieved by use of isoenzymes, concerted feedback regulation and cumulative feedback regulation. These regulatory effect can be of two types: inhibition of enzyme activity and repression of enzyme synthesis. Where isoenzymes (multiple enzyme forms capable of catalysing the same reaction) are involved, the synthesis or inhibition of each enzyme form may be regulated by a different end-product. With concerted feedback regulation, only one enzyme is involved, but more than one product must be present to inhibit activity or repress enzyme synthesis. With cumulative feedback regulation, each end-product causes partial inhibition or repression and all end-products are required to completely block activity or synthesis.1.In the first sentence, ‘a common enzyme sequence’ means:(1)the reaction sequence catalysed by the enzymes(2)that the enzyme has the same amino acids sequence2.In concerted feedback regulation the enzyme is inhibited and repressed by(1)several kinds of end-products(2)only one kind of end-product3.The isoenzymes means:(1)the enzymes have different functions(2)the enzymes are capable of catalysing the same reaction4.With cumulative feedback regulation, each end-product causes:(1)complete inhibition and repression(2)partial inhibition or repression(二）Immobilization of enzymesEnzymes are often used as nonrecoverable chemical reagents, in which case they are added to the substrate incubated at the required temperature and pH for a period and subsequently destroyed. Amylase, proteases and other inexpensive bulk enzymes are used in this way. Alternatively, enzymes may be attached to an inert support (immobilized). This offers the advantages of (1) recovery andre-use of the enzymes, in batch reactors; or (2) the development of continuously operated enzyme reactions similar to continuous fermentation systems used for microorganisms; (3) the possibility of multi-enzyme systems; and (4) the enzyme does not remain in the processed solution. However, there are some disadvantages, the enzyme may be stabilized by immobilization but it may also lose activity, and the process becomes technically more complex.There are many ways to immobilize enzymes, the common procedures involve (1)absorption to an insoluble support of either organic or inorganic origin. Cellulose, dextran, nylon and bentonite are some of the many carriers that have been used. Attachment may be by physical adsorption, ionic binding or covalent bonding. (2) Entrapment methods in which the enzyme is localized within a polymer matrix are popular and include gel or fiber entrapment and microencapsulation in which the enzyme is enclosed within sperical semipermeable polymer membranes. (3) A simple but effective procedure is to immobilize the enzyme within the host cell by heat treatment or covalent cross-linking following by pelleting the cells.Are the following statements true or false?（1）Amylase, proteases and other inexpensive bulk enzymes are destroyed after the enzyme-catalyzed reaction is completed ( )（2）The advantages of immobilization of the enzymes include the stability of the enzymes and the increase of the enzyme activity ( )（3）By immobilization of the enzymes, it is possible to operate the enzyme reactions continuously ( )（4）In the last paragraph, the word “insoluble support” has the same meaning as the word “carrier”四、英译汉（共2小题，每小题10分，共20分）(1) Controls over the enzymes of different pathways allow cells to direct the flow of nutrients, building materials, waste products, hormones, and so on in suitable ways. When you eat too much sugar, enzymes in your liver cells act on the excess, converting it first to glucose and then to glycogen or fat. When your body uses up glucose and needs more, enzymes break down glycogen to release its glucose subunits. In this case, a hormone called glucagon(胰高血糖素) acts as a control over enzyme activity. It stimulates the key enzyme in the pathway by which glycogen is degraded, and it inhibits the enzyme that catalyzes glycogen formation..(2) For a virus to multiply. It must first infect a cell. At the onset of infection, the virus introduces into the cell its genetic material—RNA or DNA—accompanied in many instances by essential proteins. They replicate inside specific host cells by using the biosynthetic systems of the host under the direction of the viral genomes.

专业英语试题----翻译资料B
1.
The signal generating device is used to give the electric circuit or the equipment input signal, in order to maintain and modify either the electric circuit or the equipment. It converts DC to AC or varying DC in the form of sine waves, square waves, triangle wave, or other types of voltage waveforms. Some signal generating device may use to generate the special audio frequency, RF(Radio Freqency), or higher frequencies,some may produce many kinds of frequency range signal. All generators will have a function switch, a frequency range switch, and a fine adjustment control for selecting a specific frequency, an amplitude control for varying the peak to peak output voltage, and output terminals.
2.
This curriculum mainly introduces the characteristics of semiconductor devices in linear application scope.The content involved in semiconductor diodes (PN junction diodes, special purpose diodes), transistors (field effects and bipolar transistors), signal amplifiers, practical amplifiers, biasing circuits, operational amplifiers circuit and other circuits (rectification, regulation and DC power supplies).
3.
Let us take a very simple but striking example. Consider a requirement for an amplifier having a voltage gain of 10 at 50 kHz
driving into a 10 k load. A common low-cost, internally frequency-compensated op amp is chosen; it has the required bandwidth at a closed-loop gain of 10, and it would seem to meet the bill. The device is connected, and it is found to have the correct gain. But it will only produce a few volts output swing when the data clearly shows that the output should be capable of driving to within two or three volts of the supply rails. The designer has forgotten that the maximum output voltage swing is severely limited by frequency, and that the maximum low-frequency output swing becomes limited at about 10 kHz. Of course, the information is in fact on the data sheet, but its relevance has not been appreciated. This sort of problem occurs regularly for the inexperienced designer. So the moral is clear: always take the necessary time to write down the full operating requirements before attempting a design. Attention to the detail of the performance specification will always be beneficial
4.
The disadvantages can include increased manufacturing and design time, increased non-recurring engineering costs, more complexity in the CAD system and a much higher skill requirement on the part of the design team.
1. 讯号产生器是用来给电路或设备的输入信号，以维护和修改电路或设备。
它
转换DC- AC或正弦波，方波，三角波，或其他类型的电压波形的形式在不同的直流。
某些信号产生的设备可能会使用产生特殊的音频，RF（无线电Freqency），或更高的频率，有些人可能会产生多种频率范围的信号。
所有发电机将功能开关，频率范围开关，并为选择一个特定的频率微调控制，不同的峰峰值输出电压的幅度控制，输出端子。
2. 本课程主要介绍半导体器件的特点，在半导体二极管（PN结二极管，特殊
用途的二极管），晶体管（场效果和双极晶体管），信号放大器，实际的放大器，偏置电路，运算放大器线性应用程序scope.The涉及的内容电路和其他电路（整顿，监管和直流电源）。
3. 让我们采取一个很简单的，但突出的例子。
考虑成10 K 负载在50千赫驾
驶10电压增益放大器的要求。
一个共同的低成本，内部频率补偿的运算放大器选择，它已在10闭环增益所需要的带宽，它似乎满足该法案。
设备已连接，并发现有正确的增益。
但它只能产生几伏的输出摆幅，当数据清楚地表明，输出应能够驱动两个或三个伏电源轨。
设计者忘记的最大输出电压摆幅，造成严重的频率的限制，并在大约10千赫的限制，成为最大的低频输出摆幅。
当然，实际上在数据表上的信息，但其相关性并没有受到赞赏。
这类问题经常发生的没有经验的设计师。
所以道德是明确的：总是采取必要的时间写下来，然后再尝试设计的完整的操作要求。
注意性能规格的细节将永远是有益的
4. 缺点包括增加制造和设计时间，增加非经常性工程成本，更在CAD系统中
的复杂性和设计团队的一部分技能要求高得多。
