If you had awakened on the floor of the Las Vegas Convention Center and tried to figure out where you were, you might have first guessed the Conclave (秘密會議) of American Optimists. You would have seen 115,000 people buzzing with confidence and excitement. On the other hand, noting how many passers-by were loudly talking to themselves, you might have concluded that you had wandered into the International Expo of Eccentrics. Instead, it was the 2003 Consumer Electronics Show, also known as CES, held in Jan. 9th –12th. No wonder those attending were happy.
First, of course, they were in their element, surrounded by the smallest and shiniest new gadgets (小配件). Second, despite the gloom in other slices of the economy, sales of consumer electronics in the United States actually grew last year (to a record $96 billion). This trade show of manufacturers, retailers and customers was alive with energy and crowded with exhibits.
The vitality of this exposition is a sign of the times. The interest and innovation in PCs is nothing next to the action in other realms of high tech. As proof, compare the show with what was once its big brother: Comdex, the personal-computer trade show held each November at the same site. Thanks to the severe decline in the PC industry, the 2002 Las Vegas Comdex was only half the size of its 2000 incarnation.
The 2,200 booths included lavish displays by Panasonic, Sony, Philips, Toshiba and other heavy hitters. But hundreds of smaller, quirkier companies were also present, exhibiting electric toothbrushes, illuminated cell-phone faceplates, laser pens and publications from Widescreen Review to Progressive Grocer. There were 46 exhibitors in the alarm-clock category alone, and even an electric-typewriter company.
To reach those smaller booths, though, you had to pass what seemed like half the $10,000 plasma(等離子)TV screens ever made. This proliferation(豐富) of gorgeous wide-screen sets was only one hint that TV makers, at least, are ready for the great American switch to high-definition television, which the Federal Communications Commission hopes to see completed by 2006.
But a few obstacles stand between the average American and high-def happiness: the prices of these sets, the reluctance of cable companies to broadcast high-definition shows, Hollywood’s campaign to cripple high-definition broadcasts so that you can’t record them, and so on. (As many seminar panelists observed, however, strides are being made in all those areas.)
The most interesting items at Microsoft's booth were the prototype wristwatches that use the company’s new Smart Personal Object Technology (SPOT) software. Due by year’s end from Citizen, Fossil and other companies, these watches can receive messages, news, weather, sports and stock reports wirelessly in metropolitan areas for a small monthly fee, of course.
The most alarming item at Microsoft's booth, on the other hand, was its six-room mock-up of an American house with Microsoft products—cars, phones, TVs, games, appliances—in every nook and cranny. It’s only a matter of time before you'll see people rebooting their toasters.
The digital camera models on display were cheaper, better and smaller than their predecessors. Olympus’s Stylus 400, for example, is a tiny, silver, pocketable wonder that takes four-megapixel photos (enough resolution for 13-by-19-inch prints). It’s due in the spring for $400.

For many years the automation research departments of the world have been using laser based analysis system to increase the understanding of the workings of the internal combustion engine. The laser has been incorporated into systems to measure drop size, velocity and vibration to name but a few. But few laser-based systems are able to aid the study of all these phenomena with the same system. The Applied Optics Group at Rover Groups Gardon Research & Development Center have been using just such a system and finding new uses for it all the time.
The system in use is a High Speed Imagining Division of Oxford Lasers LTD. The High Speed Imaging system comprises an Oxford Lasers LS20 Copper Vapor laser linked to a Kodak 4540 Digital High Speed Motion Analysis Camera capable of taking up to 40,500 digital frames per second. The Kodak 4540 records the images to DRAM memory allowing immediate play back of the recorded images for viewing, recording to videotape or to PC for analysis. The Copper Vapor laser acts as a short duration flash emitting pulses of only 30 nanoseconds in duration in full synchronization with the frame rate of the camera The flashes have the effect of reducing the exposure time of the camera, thus removing image blur due to the high speed of the subject under view, whilst maintaining image contrast due to the high intensity of the laser light. Another feature of the system is the ability to focus down the light. This has two benefits. The first is the ability to make laser light sheets for the 2 dimensional illumination of 3 dimensional subjects. This technique has great benefit when used to map the air flow into the combustion chamber of a running model engine. Not only can the air-flow be mapped but the progress of the flame front growth during the combustion cycle. The second is the ability to shine the laser light down a fiber optic cable. This aids in the illumination of areas of the running engine very difficult to access by normal optics. This has been particularly useful in the study of air motion in a variety of combustion system concepts.
The group plans to use the Copper Vapor laser to improve the ability of the technique to see these vibrations and therefore allow a better understanding of the cause of them. The technique could also applied to look at the airbag enclosure as it tears and composite materials under dynamic crush testing.
6. How many uses of the laser-based analysis system does the author want to show us?
[A] One [B] Two [C] Three [D] Much more than three
7. Which of the following does the High Speed Imaging system comprise ________.
[A] an Oxford Lasers LS20 Copper Vapor laser
[B] 4540 Digital High Speed Motion Analysis system
[C] DRAM memory allowing immediate play back of the recorded images for viewing
[D] a High Speed Imagining Division of Oxford Lasers LTD.
8. Which of the following is the main advantage of the laser flashes?
[A] Keeping image contrast [B] getting rid of image blur
[C] Increase the intensity of light [D] All is said in A, B, and C
9. Which of the following uses is NOT TRUE according to the passage?
[A] The laser light can help to make the three dimensional bodies look as if they were of two dimensions.
[B] The air-flow can thus be made easier to be mapped with the laser.
[C] The turning speed of the combustion engine can be accelerated by using vapor laser.
[D] The exposure time of the camera can be reduced by the laser flashes.
10. Which of the following can be the best title of the passage?
[A]At the Speed of Light
[B] A High Speed Imagining Division Made by the Oxford Lasers LTD.
[C] A Miraculous Application of Laser in Testing the Internal Combustion Engine
[D] Automobile research and Laser Technology
答案： D A D C C
