The Dazzle of Lasers(激光)
The acronym（首字母缩写词）"laser," describes how the device works: Light Amplification by Stimulated Emission of Radiation. 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 machine
that 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 being
launched.
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.

Your Next Computer
Technology revolutions come in two flavors: jarringly fast and imperceptibly slow. The fast kind, like the sudden prevalence of iPods or the proliferation of music-sharing sites on the Net, seem to instantly reshape the cultural landscape. The slower changes grind away over the course of decades, subtly transforming the way we live and work.
There are 1.5 billion cell phones in the world today, more than three times the number of PCs. Mobile phones are so integral to our lives that it’s difficult to remember how we ever got on without them.
As our phones get smarter, smaller and faster, and enable users to connect at high speeds to the Internet, an obvious question arises: is the mobile handset turning into the next computer? In one sense, it already has. Today’s most sophisticated phones have the processing power of a mid-1990s PC while consuming 100 times less electricity. And more and more of today’s phones have computer-like features, allowing their owners to send e-mail, browse the Web and even take photos; 84 million phones with digital cameras were shipped last year. Tweak the question, though, to ask whether mobile phones will ever eclipse, or replace, the PC, and the issue suddenly becomes controversial. PC proponents say phones are too small and connect too sluggishly to the Internet to become effective at tasks now performed on the luxuriously large screens and keyboards of today’s computers. Fans of the phone respond: just wait. Coming innovations will solve the limitations of the phone. “One day, 2 or3 billion people will have cell phones, and they are all not going to have PCs.”Says Jeff Hwakins, inventor of the Palm Pilot and the chief technology officer of PalmOne. “The mobile phone will become their digital life.”
PalmOne is among the firms racing to develop the full-featured computerlike phones that the industry calls “smartphones”. Hawkins’s newest product, the sleek pocket-size Treo 600, has a tiny keyboard, a built-in(内置的) digital camera and slots for added memory. Other device makers have introduced their own unique versions of the smartphone. Nokia’s N_Gage, launched last fall, with a new version to hit stores this month, plays videogames. Motorola’s upcoming MPX has a nifty “dual-hinge” design: the handset opens in one direction and looks like a regular phone, but it also flips open along another axis and looks like an email device, with the expanded phone keypad serving as a small QWERTY keyboard(标准键盘). There are also smartphones(智能手机) on the way with video cameras, GPS antennas and access to local Wi-Fi hotspots(热点), the superfast wireless networks often found in offices, airports and local cafés. There’s not a phone that doubles as an electric toothbrush, but that can’t be far.
But it’s not all mobile technologists think the ultimate promise of the mobile phone ends there. Could your phone one day actually perform many of the functions of the PC, like word processing and Web browsing? PalmOne’s Hawkins thinks so. Within the next few decades, he predicts, all phones will become mobile phones; all networks will be capable of receiving voice and Internet signals at broadband speeds, and all mobile bills will shrink to only a few dollars as the phone companies pay off their investments in the new networks. The computer won’t go away, he says, but it might fade to the background, since people prefer portability and devices that turn
on instantly instead of having to boot up.
Defenders of the PC react with religious outrage to this kind of prophecy. Laptops(笔记本电脑) allow another kind of mobile computing, they point out, particularly with the emergence of thousands of Wi-Fi networks around the world over the past four years. By the end of this year half of all laptops shipped will be Wi-Fi-equipped, allowing laptop owners to set up temporary offices in the local caféor public park. Then there’s the matter of simple practicality: mobile phones are small and getting smaller. Humans are not. “Hundreds of millions of people are not going to replace the full screen, mouse and keyboard experience with staring at a little screen,”says Sean Maloney, an executive VP at Intel.
Yet mobile-phone innovators are working to solve that tricky problem, too. Scientists are continuing decades of research into speech-recognition systems and have recently introduced the technology into PDAs. Users can control these gadgets with simple voice commands.Other innovators are working on improving the keyboard instead of abandoning it altogether.
Cell phones aren’t likely to take the fastest road to this bright future. Innovations in the mobile industry is full of wrong turns, often because no single company completely controls the device in your pocket. Local carriers sell the phone to customers, provide bills and run the phone network; device makers like Sony, Nokia and Samsung design the phone itself, and outsource the actual manufacturing to factories in China. Another change is that, unlike the Internet, the phone world has no open and single set of protocols for programmers to build around. Software written for one kind of phone won’t wok on all others. The uncoordinated, noncommercial programming that led to the quick evolution of the Internet hasn’t taken hold in the world of mobile phones.

Earthquake Prediction
Earthquake prediction is an imprecise science, and to illustrate the point, many experts point to the story Tangshan, China. On July 28, 1976, a magnitude 7.6 earthquake stuck the city of Tangshan, China, without warning. None of the signs of the successful prediction from a year and half earlier were present. An estimated 250,000 people died.
Unlike thirty years ago, however, earthquake scientists today have a few more tools at their fingertips to help predict temblors. Raymond, a geophysicist(地球物理学家), says the application of an emerging satellite technology “could advance earthquake science towards a better predicative capability.”
The system, known as the Global Earthquake Satellite System (GESS), employs a technology called interferometer synthetic aperture radar (InSAR).（合成孔径雷达干涉测量技术）The technology allows scientists to detect minute deformations（变形）in the Earth’s crust（地壳）. In theory, knowing how and where the Earth’s crust is deforming, combined with knowledge of how earthquakes work, could give scientists a clue that an earthquake is going to happen. Max Wyss, director of the World Agency of Planetary Monitoring and Earthquake Risk Reduction, said that “InSAR is a great new technology that allows us to illuminate the surface of the planet and map the deformation that happens. And it is very reasonable that Earth deformation may happen before an earthquake.” But he also stated that the InSAR technique can not be seen completely reliable because there is little evidence that the Earth actually deforms before a major earthquake.
The InSAR technique involves examining pairs of radar images of the same landscape to determine changes in the land surface over very broad regions to within a couple of inches. The satellites can thus detect slight deformations in the Earth’s crust, which may indicate strain prior to an earthquake.
The space shuttle flew a mission in 2000 that used the technology to create a geographic map of the Earth. A proposal to launch an InSAR equipped satellite is currently before NASA. Scientists hope that within 20 years, several more satellites will launch. Raymond said that while a single InSAR-equipped satellite would be useful, a group of such satellites would deliver an extremely dense data set for use by earthquake prediction scientists.
As scientists wait for the network of InSAR satellite to be realized, sophisticated global positioning system (GPS) networks are being used to monitor the Earth’s crust. This information is helping scientists create models of complex Earth deformation.
Many of us know that earthquakes are a sudden release of energy caused by the sliding of a part of the Earth’s crust along a fault(断层). But Raymond adds that scientific evidence suggests the Earth also release stress via a slow process. In such cases, there is no shaking and damage to buildings. Scientists are uncertain as to how much of the overall stress in the Earth is released in this manner, but InSAR may help to answer the question.

3）但是他也同时指出，InSAR技术并不时完全可靠的，因为几乎没有证据表明在大地震前地壳真的会变形。
4）卫星从而可以探测出地壳的微小形变，它或许可以表明地震前的压力迹象。
5）科学家们并不清楚，地球内部总共有多少压力是以这种方式释放出来的。Answers：
1.earthquake
2.It is not precise enough, because there is little evidence that the Earth actually
deforms before a major earthquake.
3.The InSAR technique involves examining pairs of radar images of the same
landscape to determine changes in the land surface over very broad regions to within a couple of inches.
4.global positioning system (GPS)
5.Earthquakes are a sudden release of energy caused by the sliding of a part of the
Earth’s crust along a fault(断层).
Summary:
The article introduces the application of an emerging satellite technology, InSAR technique, towards the earthquake prediction.

科技英语翻译的原则_方法及技巧.
翻译是把一种语言里已经表达出来的事物用另一种语言准确流畅地进行重新表达的过程。与其他题材的文章相比,科技专业文章在内容、表达形式和风格上有很大的差别,具有科技性强、专业性强、逻辑严密、表达要求简练的特点,在翻译上力求准确全面、严谨明确和通顺简练。 1科技英语翻译遵循的基本原则 从科技文章的特点来看,大多具有以下几个特征:述说事理、逻辑性强、结构严密、术语繁多,语言严谨、数据精确。这就要求译文必须概念清楚、条理分明、逻辑正确、数据无误,尤其对定义、定律、公式、图表、结论等更应特别注意。科技英语作为特殊英语的一个分支,在词汇构成、遣词造句等方面都有其自身的特点,其语法结构不十分严密、语言习惯和汉语也有不少差别、词汇量大、词语繁多,因此科技英语翻译起来比较困难。另外,科技文章比较重视叙事逻辑上的连贯及表达上的明晰与畅达; 避免行文晦涩,避免表露个人感情,避免论证上的主观随意性。因此,科技英语翻译力求少用或不用描述性形容词以及具有抒情作用的副词、感叹词及疑问词,而是大量使用科技词汇、专业技术用语,译者应尊重客观事实,不能随意改动数据、回避不易翻译的文字,更不能加进自己的主观想象,进行自由翻译。 我国著名翻译家严复提出的“信、达、雅”三准则一直为不少翻译工作者所接受。 “信”指的是译文要忠实于原文,“达”是指译文的通顺达意,“雅”指的是译文的用词修辞。三准则体现了译文和原文信息等值这一基本要领。 “信、达、雅”的翻译准则对各种英语文体的翻译实践都具有指导意义,是衡量一篇译文好坏的标准,也同样适用于科技文献的翻译。由于科技文章特有的文体特征,与其他类文章相比,其“达”和“雅”的内涵不同,它要求在准确传达信息的基础上,使译文更加简洁明快,流畅通顺。2科技英语翻译的基本方法
