In 1916 Einstein predicted that electrons(电子) in an atom could be deliberately stimulated to emit photons（光子） (light energy) of a certain wavelength. He was right. The laser must first be "pumped" with energy in a variety of ways so that the electrons are excited into higher energy states. But these high energy electrons are unstable--and fall back to a lower energy level. On the way down, their extra energy is released（释放）as light. That light is captured inside the laser and amplified by bouncing it back and forth between mirrors. The laser beam that emerges is amplified, monochromatic （单色的）, coherent light --and it shines with an unearthly power.Not until 1960 did Theodore Maiman, a 33-year-old engineer at Hughes Research Laboratories, build a homely four-inch cylinder containing a ruby rod encircled by a flash tube: the world's first working laser.More than two decades later, the laser has wrought a technological revolution. Lasers are an indispensable tool for delicate eye surgery, and doctors are using lasers experimentally to destroy cancerous tumors(肿瘤), unclog（使畅通） diseased arteries （动脉） and even treat herpes（疱疹）. Just as they provide new tools for health care, however, they also make possible new engines of destruction: recently Dr. Edward Teller, the father of the hydrogen bomb（氢弹）, called on President Reagon to urge that the United States build a space-based laser-weapon system that would use a nuclear bomb to fire brutally intense laser X-rays against enemy missiles in flight.Today pilots flying the new Boeing 767 and 757 aircraft navigate with the aid of new laser gyroscopes（陀螺仪）. Supermarket clerks use lasers to ring up prices at the checkout counter by "reading" universal bar-codes（条形码） printed on packages and canned goods. Powerful lasers cut and weld（焊） steel in factories from Detroit to Tokyo. Artists and filmmakers are beginning to use lasers for animation（动画）: at Lucasfilm, George Lucas has a team of computer wizards（奇才） developing a machinethat uses a computer-driven laser to draw animated images on film; a second film, with human actors, is then merged by laser with the graphics into a single seamless （无缝的） whole.How does the laser work? Anyone who has ever focused sunlight through a magnifying glass and watched paper or dry leaves snap into flames understands the power of concentrated light. Laser light is intense, concentrated light, too, but it works on a different principle. Shine sunlight through a prism（棱镜） and it breaks into the glorious colors of the rainbow. In the scientists' vocabulary, sunlight is "incoherent" --it is made up of a mix of wavelengths spanning the spectrum（光谱）from infrared（红外线） to ultraviolet（紫外线）. Laser light, on the other hand, is monochromatic and coherent－it shines at a single wavelength, and all the light waves march together in step like soldiers on parade（游行）.In the two decades since its invention, the laser has undergone a dramatic transformation: a wide variety of gas, solid-state, diode（二极管） and other lasers has been created. Each shines at a different wavelength; some pulse on and off, others operate continuously.When the laser moved out of the laboratory, one of its first and most significant applications was as a medical tool. Lasers are commonly used for delicate surgery inside the eye. In treating blood-vessel disorders resulting from complications(并发症) of diabetes（糖尿病）, doctors aim a fine beam of argon laser light（氩激光） through the pupil（瞳孔） of the eye and place up to 2000 tiny laser burns very closely around the back portion of the retina（视网膜）. These laser "welds" prevent harmful growth or rupture（断裂） of new, unwanted blood vessels.The very properties that make lasers dangerous --power and heat--are also being put to use to destroy some kinds of brain and spinal（脊髓的） tumors. Lasers have brought a new frontier to neurosurgery（神经外科）. They have made some inoperable tumors operable and high-risk tumors less high risk.Warfare is also changing as laser technology advances. Laser guidance systems have brought once unimaginable accuracy to artillery（炮）. In the near future, higher-intensity lasers may be used to blind the electronic sensory systems of aircraft, missiles, tanks and ships. And ultimately, some visionaries insists, the globe could be surrounded by a platoon（排） of orbiting battle stations armed with lasers capable of destroying planes and missiles within seconds of their beinglaunched.Just as they are opening new doors to medicine and military practices, lasers are also having a profound impact on communications. Instead of sunbeams, today's light-wave communication systems use laser light ricocheting through tiny glass fibers. Lasers generate light waves at extraordinarily high frequencies--in the range of trillions of cycles per second --which makes it possible to transmit enormous quantities of information. In addition, fiber-optic cables are cheaper than copper wire and are not subject to electromagnetic interference, or the annoying cross talk（串话） and static that plague（折磨） current systems. The big breakthrough was the semiconductor laser.Someday laser light may be piped through giant optic cables into deep ocean waters to create undersea farms; it may be beamed into space to talk to orbiting space stations. Lasers also may be used to fire extremely precise light pulses at DNA molecules, altering the structure of chromosomes（染色体） and thereby repairing defective genes --or even creating new forms of life. And eventually billions of lasers will link the world in a vast information network, a global village of light.1.How does the laser work?2.What is the difference between sunlight and the laser?3.Is the laser absolutely safe? If not, please explain.4.What are the advantages of the semiconductor laser in the communications field?5.In what fields is the laser applied?Part one:1.For this purpose, it is necessary to have a good understanding of the fundamentals of thecircuit.2.This coefficient remains to be determined.3.None of the textbook available mentions this point.4.Since feedback plays an important role in the electronic circuit, its study is very important.5.There is an indication that the price of computers will fall further.6.This method does work, but it is not clear in what condition it is that it should be used.7.The output of this factory 10 years ago is 6 times what it is now.8. A new technology introduced in the 1960s, laser can pierce very hard substances.9.For the transistor to work normally, it is necessary to apply a proper voltage across theelectrode.10.The magnetic lines of force representing the magnetic field are some concentric circlessurrounding the wire.11.What is called a robot is a tool which can do work for the human being.12.This type of antenna has the advantages over that one of simple structure and high efficiency.13.Semiconductors are sensitive to light and hear, both of which have a great impact onconductivity.14.Only through a study of the system’s performance is it possible to know its advantages anddisadvantages.15.This book discusses both practical design method and theoretical problems with emphasis onthe basic concept.Part two:1.It is easy to determine the effect of the new drug on the patient.2.The direction of the electric current had been decided before electrons were discovered.3.Sound travels much more slowly that light does.4.This instrument is expensive.5.There are a few exceptions to this rule.6.The hotter the body is, the more energy it radiates.7.This device is small and light.8.That professor is much interested in this topic.9.Our semiconductor industry came into being at the end of the 1950s.10.Both the engineers are busy designing a new type of computer.11.Work equals force multiplied by distance.12.The newly designed instrument is good in quality.13.The ability of some elements ot give off radiations is referred as the radioactivity.Part three:Translation:1. 20多年前，激光引发了一场技术革命。

1 .With speed increasingly seen as the key to competitive advantage, the dream is to marry the control of an established company with the responsiveness of a start-up. As Linda Applegate reports, advances in IT now means that the “big small”company is finally feasible.In the hierarchical companies of the 1960s and 1970s, informaiton moved slowly and channels of communication were limited. Over the past few years, however, large companies have come under ever-increasing pressure to collect, process and distribute information more quickly in order to compete with smaller, more nimble rivals. The key challenge facing any sizeable organisation today is how to achieve responsiveness without losing the control inherent in a hierarchical structure.All types of organisation are controlled through two sets of processes. Operating processes define how a company produces, sells, distributes and supports its products and services. Management processes define how a company directs, coordinates and controls these operations. Typical management processes include planning, budgeting and human resource management.Traditional hierarchical organisiations control operating processes through standardisations of jobs. These jobs are separated into sequential steps and carried out under direct supervision. However, the line workers lack both the authority and motivation to improve these routine tasks and are limited by their local view of the business. Management processes in such companies are also hampered by the time it takes to recognise that change is needed. Thus, hierarchical control is only truly effective in relatively stable business environments where change happens slowly.Entrepreneurial organisations, on the other hand, allow fast response without any loss of control. Daily personal interaction between the owner and employees ensures flexibility and responsiveness, while instant feedback ensures effective control. However, as the company becomes larger and more complex, this control breaks down and more structured operating and management processes required.Information age organisations can manage the complexity of the large hierarchical structure without losing the speed of the entrepreneurial start-up. IT plays a critical role. It coordinates complex fast-cycle operating processes and, more importantly, gives decision-makers quick access to detailed, real-time information about operations and market performance. Once all the information is flowing, employees can quickly evaluate their decisions and continually refine both strategy and operations. Organisational control then becomes a dynamic, information-enabled learning process rather than a static monitoring system.However, although IT makes the “big small” company possible, it can not motivate people to use information in order to act on behalf of the organisation. The challenge for organisation is therefore to ensure that managers and employees share the same perspective on the business and are motivated to accomplish the same goals。

科技英语翻译大作业(科技英语6&13班)I.全篇翻译passage1：Passage１Billing for goods and services that customers have purchased is part of any business. Traditional billing methods in the brick-and-mortar paradigms are costly and involve generating invoices, stuffing envelopes, affixing proper postage to the envelopes, and sending the invoices to the customers. Meanwhile, the accounts payable department must keep track of incoming payments, post accounts in the database, and ensure that customer data are current.Online stores have many of the same payment collection inefficiencies as their brick-and-mortar cousins. Most online customers use credit cards to pay for their purchases, while auction customers may also use conventional payments methods, including checks and money orders. Electronic cash systems, though less popular than other payment methods do provide several advantages as well as some disadvantages unique to electronic cash.For the most part, electronic cash transactions aremore efficient (and therefore less costly) than other methods, and that should foster more business, which eventually means lower prices for consumers. Transferring electronic cash on the Internet costs less than processing credit card transactions. You have observed that conventional money exchange systems require banks, banks branches, clerks, automated teller machines, and a parallel electronic transaction system to manage, transfer and dispense cash. That is expensive. On the other hand, electronic cash transfers occur across an existing infrastructure, the Internet, and through existing computer systems. So the fixed cost of hardware to handle electronic cash is nearly zero. Because the Internet spans the globe, the distance that an electronic transaction must travel does not affect cost. When considering moving physical cash and checks, distance and cost are proportional---the greater the distance that the currency has to go, the more it costs to move it. However, moving electronic currency from Detroit to San Francisco costs the same as moving it from San Francisco to Hong Dong. Everyone can use electronic cash. Merchants can pay other merchants ina business-to-business relationship, and consumers can pay each other. Electronic cash does not require that one party have any special authorization, as is required with credit card transactions.

Despite its prevalence, anxiety remains one of the most undiagnosed and undertreated conditions in this population.Examples of anxiety disorders include panic disorder, obsessive compulsive disorder, phobias and generalized anxiety disorder (GAD). GAD is characterized by exaggerated, uncontrollable worries about everyday things. 2) While many worrisome events occur as people age and while it is normal for people to be concerned about such things as deteriorating health and financial troubles, people with GAD tend to worry excessivelyand constantly.3) “Studies have shown that generalized anxiety disorder is more common in the elderly, affecting seven per cent of seniors, than depression, which affects about three per cent of seniors. Surprisingly, there is little research that has been done on this disorder in the elderly,” said Eric J. Lenze, M.D., assistant professor of psychiatry, University of Pittsburgh School of Medic ine. “Doctors often think that this disorder is rare in the elderly or that it is a normal part of aging, so they don’t diagnose or treat anxiety in their older patients, when, in fact, anxiety is quite common in the elderly and can have a serious impact o n quality of life.”This constant level of worry can have negative, and sometimes even disabling, effects on a person’s life. Many people with GAD have trouble sleeping or limit their daily activities due to their anxiety. 4) Untreated anxiety can also lead to anxious depression – a condition that is more difficult to treat and carries a higher risk of suicide than depression.“Anxiety in people over age 60 might has some similarities to anxiety in those younger, but it also hasmarked differences. We ca n’t just assume that we can treat the two age groups the same,” said Dr. Lenze. 5) “We are decades behind where we need to be in terms of research and treatments for anxiety in this older age group.” There are, however, encouraging signs that studies are beginning to address treatment options. What It Means: Anxious older adults and their families should be aware of the prevalence of anxiety disorders. Excessive fretting should not be considered an inevitable sign of aging. A small pilot study conducted at the University of Pittsburgh has shown that ananti-depressant drug was also effective in treating anxiety in older adults. Additional studies hope to address the role of cognitive behavioral therapy or other therapies for anxiety in the elderly. There are indeed enough things to worry about when growing older. But uncontrollable, excessive worry shouldn’t be among them. (453 words)。

From records taken over many months it was found that the personal efficiency of those wearing ear defenders had increased by 7 percent.6. The damage caused by acid rain can be alleviated by adding lime to lakes, rivers and streams and/or their catchment areas.7.In fact, it is impossible for no force to be exerted on a body, since in this world everything is subject to the force of gravity.8. In Germany, a group of amateur enthusiasts, inspired by dreams of inter-planetary travel, were conducting their own, occasionally fatal, experiments on liquid-fuelled rockets.9.The strength of the current flowing through the electric circuit between two points depends on the reisistance and on the voltage between the points.10.The computer performs a supervisory function in the liquid-control system by analyzing the process conditions against desired performance criteria and determining the change in process variables to achieve optimum operation.II. Translate the following passages into Chinese. (80%)Passage one （25%）Operating From A.C. Power Supply＊Inserting the A.C. supply lead into the unit automatically disconnects the batteries. As a result, the A.C. supply must be removed from the unit in order to operate the unit on battery power.＊Disconnect the A.C. supply lead plug from the A.C.outlet when the unit is not in use for extended periods.Operations From D.C. Power Supply: Batteries＊Remove the batteries when they become weak or when the unit is not in use for extended periods. This will prevent damage to the unit from battery leakage at such times.＊Be sure to keep battery contact parts clean. Dust accumulations between batteries and battery terminals may result in imperfect contacts, and may even prevent the unit from operating.Passage two （25%）The Port of ShanghaiLocated in the middle China’s coastline and at the Changjiang River’s outlet to the East China Sea, the port of Shanghai faces the Pacific Ocean at the front and is supported by the city of Shanghai ---- the country’s largest economic, scientific and technological center. Access to various parts of the country is provided by rail, highway and inland navigation, which enable the Port to transship the commodities from 20 Chinese provinces. Internationally the Port has so far established trading and shipping relations with over 400 ports in more than 160 countries and regions. Its annual cargo handling has reached 400 million tons, accounting for 35% of total via 15 china’s major ports. Its international container handling capacity accounts for 33% of that ofChina’s ports along the coast.To accomplish the modern shipping need, the Port of Shanghai is quickening the construction and professional development of internantional container berths. The operation adopts advanced handling methods and computer technology, with container cranes at quayside and other heavy-duty machinery in the yard.Passage three （30%）Machine TranslationMachine translation, or natural language handling, has been one of the items of artificial intelligence, dealing with sentences and paragraphs, not only words and phrases. Its steps are: logically analyzing source sentences by computer, identifying the components in a sentence, making reference to a dictionary prestored in a computer, and then translating the sentences one by one.Since 1980s a number of Chinese universities have been engaged in both E-C and C-E translation software development. The study centered on: 1. analyzing syntax relationship between Chinese words and phrases; 2. summarizing typical Chines sentences into standard sentence patterns. It is reported that a library convering 10 years’People Daily containing 2,000 structures and 10,000 typical sentence patterns, has been compiled for use in translation of political articles.Computers have helped somewhat through the development of artificial languages that are to be used as a medium. If this succeeds, then C-E translation may be carried out in two steps: first from Chinese to the medium and, second, from the medium to English. E-C translation may be done in the reverse dircetion. But none of artificial languages so far has proved completely adequate, since computers are incapable of discerning the meanings.。
