科技英语课文翻译1-7

参考译文Unit 1课文A石油1油，和煤一样，存在于沉积岩中，而且可能由死去很长时间的生物有机体形成。

含有石油的岩石几乎都来源于海洋，所以形成石油的有机物一定是海洋生物，而不是树木。

2 石油，并不是来自于逐渐积聚的木质物质，而可能是来自于逐渐积聚的海洋生物的脂肪物质。

比如浮游生物：大量浮游在海水表层的单细胞生物。

3 有机物的脂肪物质主要由碳氢原子组成，因此并不需要太多的化学变化就可以形成石油。

生物有机体只需在缺氧的条件下沉积到海湾浅水处的淤泥里。

其脂肪不是分解腐烂，而是逐渐积聚，并在深层的淤泥里圈闭起来，进而经过细微的原子重组，最终形成石油。

4 油比水轻，呈液态，会经由上方覆盖的孔隙性岩石向上渗透，在地球上有些地区到达表层，古人将这些表层石油称为沥青、柏油或异庚烷。

在古代和中世纪，这些石油油苗常被看作药品而不是燃料。

5 当然，表层的油苗数量很少。

而石油油藏上方有时覆盖的是非孔隙性岩石。

石油向上渗透抵达该岩石，然后在岩石下方逐渐积聚形成油层。

若在上方的岩石上钻个孔，石油就可以通过该孔向上迁移。

有时压力过大，石油会向高空喷出。

1859年在宾夕法尼亚州，由埃德温·德雷克成功打出第一口井。

6 如果可以发现一个合适的地点（勘探人员已经识别出地下可能圈闭有石油的地层结构），那么就很容易抽取这一液体燃料，这要比派人到地下把大块的固体煤炭砍成小块要容易得多。

而且一旦获得石油，可以通过地上管道运输，而不必像煤一样，由运货车经过繁重的装卸任务来运输。

7 石油便于抽取，易于运输，促进了石油的应用。

石油可以蒸馏成不同的馏分，每种馏分均由特定大小的分子组成，分子越小，该馏分就越容易蒸发。

8 到19世纪下半叶，最重要的石油馏分是由中等大小的分子构成的煤油，它不易蒸发，被用于照明。

9 然而，到19世纪末人们研制出了内燃机。

内燃机是通过在汽缸里将空气与可燃气体混合，产生爆炸来提供动力的。

最便利的可燃气体是汽油——石油的又一馏分，由小分子构成，容易蒸发。

科技英语课文翻译课文翻译英语Unit 1罗素悖论的提出是基于这样的一个事例：设想有这样一群理发师，他们只给不给自己理发的人理发。

假设其中一个理发师符合上述的条件，不给自己理发；然而按照要求，他必须要给自己理发。

但是在这个集合中没有人会给自己理发。

（如果这样的话，这个理发师必定是给别人理发还要给自己理发）1901年，伯特兰罗素悖论的发现打击了他其中的一个数学家同事。

在19世纪后期，弗雷格尝试发展一个基本原理以便数学上能使用符号逻辑。

他确立了形式表达式（如：应。

一种类比是救护车的汽笛声会改变音高――当它朝你行驶，然后通过你身边接着朝另一个方向去了的时候――他的声波首先是压缩的，接着伸长这些测量给了天文学家一个关于宇宙在不同历史点的膨胀速度的图景。

研究人员还发现宇宙如今正在以前所未有的速度在膨胀。

“一开始我们不情愿相信我们的结果，”加州大学伯克利分校的劳伦斯伯克利实验室的天体物理学家Saul Perlmutter说，他领导的一个竞争性的小组发现了和Schmidt以及Riess 相同的结果。

x =2）和数学特性（如偶数）之间的联系。

按照弗雷格理论的发展，我们能自由的用一个特性去定义更多更深远的特性。

1903年，发表在《数学原理》上的罗素悖论从根本上揭示了弗雷格这种集合系统的局限性。

型的集合系统能很好的用俗称集的结构式来描述。

就现在而言，这种类们可以用x代表整数，通过n来表示并且n大于3例如，小于我7，来表示x={n4，5,6这样一个集合。

这种集合的书写形势就是：我们也可让：n是整数，y={x：3n7}x是美国的一个男性居民。

集合中的对象并不一定是数字。

}。

求的空间。

但是，罗素（和策梅洛一起）发现表面上看，似乎任何一个关于x的描述都有一个符合要a中}导致一个矛盾，就像对一群理发师的描述一样。

x={a：xa它本不再身是在x有致命的打击。

尽管这样，他还不能解决这个问题当罗素发现了悖论，的集合中吗？否定的答案导致了矛盾的出现。

1all elements are composed of scattered units called atoms,which are the smallest particles than show the characteristics of the element. atoms are tiny units of matter composed of positively charged protons, negatively charged elements ,and electrically neutral neutrons. protons and neutrons, which have almost the same mass,are clustered in the nucleus in the middle of the atom. electrons,which are tiny in comparison to the other units, move around the nucleus at high speed. atoms that have the same number of electrons and protons are electrically neutral. those that have got or lost electrons,and therefor are positively or negatively charged, are called ions.所有的元素都称为原子的散射单元，这是比显示的元件的特性的最小的颗粒组成。

科技英语阅读与翻译全文Humanitarian Aid in SpaceSpace exploration technology will benefit developing countries in a variety of ways. Whether it's information about climate change or communication technologies that give remote areas access to the world outside, space science can come to the aid of vulnerable people in many countries.For the past two decades, Japan Aerospace Exploration Agency (JAXA) has been sending humanitarian aid dispatched from its space platform. This ambitious project has proved successful, and it’s been praised for its achievements in various aspects.The two strategic areas set forth for JAXA’s humanitarian aid effort are science and education. JAXA’s donations of books and puzzle sets are enabling elementary and junior high school kids in India to study science and math. There are plans to utilize remote sensing data to map out natural resources in Nepalese countryside and expand education related to environmental issues in Vietnam. In addition the agency is sending educational videos to the island nation of Palau tobetter understand their own local wildlife.JAXA is considered to be a pioneer in this area since the launch of their humanitarian aid initiative in 1997. The organization strives to make use of space applications for social welfare and reduce disparities in the world through a number of practical endeavors. The effort currently has a global reach, with projects taking place in seven continent, from Latin America to Africa.JAXA’s humanitarian aid programs will continue to grow with better technology and increased resources. The ongoing work reinforces the concept that space science and technology have the potential to contribute to enhancing the lives of people on Earth.人道主义援助在太空太空探索技术将在各个方面受益于发展中国家。

Human Geomatics in Urban Design—Two Case Studies在城市设计中的人类地理信息学——两个案例研究Małgorzata Hanzl1,*,Karol Dzik2,Paulina Kowalczyk2,Krystian Kwieciński2,Ewa Stankiewicz2and AgataŁ.Wierzbicka2Abstract:The mapping of different aspects of urban phenomena and their relation to thephysical cityscape has been greatly extended by the use of geomatics.The tradition to basereasoning on‗understanding the world‘dates from the time of Aristotle.The extensionplan for Barcelona(Eixample),developed by Cerdà,which opened the era of modern urbanplanning,was preceded by analyses of rich data,describing both detailed demographicissues and physical structures.The contemporary,postmodernist city planning continuesthis tradition,although a shift towards analyses of more human-related issues can beobserved,covering,inter alia,citizens‘perception,cultural differences and patterns ofhuman activities with regard to distinct social groups.The change towards a morehuman-related perspective and the inclusion of urban morphology analyses are directconsequences of this trend.The required data may be gathered within a crowd-sourcingparticipation process.According to communicative planning theory,communication withthe wider public is indispensable in order to achieve the best results,and can be realizedwith the use of sophisticated IT tools.Evidence-based reasoning may be supported byimages of significant aesthetic values,which inspire immediate reactions.Keywords:GIS;crowd-sourcing;mash-up;education;urban planning;urban analyses摘要：不同方面的城市现象及其与物理城市景观的关系映射经由地理信息学的使用已经大大扩展了。

Unlocking the Climate Puzzle解开气候之谜(1)Life has prospered on this planet for nearly four billion years. In that time, climate had fluctuated drastically, from ice ages lasting tens of thousands of years to epochs of steamy heat. With each change, sundry species have benefited and flourished.Others adapted, faltered， or died. Now, many experts believe， humans are imperiling their own ecological niche with the threat of global warming. The vaporous by—products of civilization， in the form of greenhouse gases such as carbon dioxide (C0₂), have trapped enough heat in the atmosphere to raise Earth's average surface air temperature a half degree Celsius (one degree Fahrenheit) during this century. If the trend continues， it could alter climate patterns worldwide-thawing glaciers， boosting sea level, scorching plains into deserts, and shifting vegetation zones。

Unit 1 EnvironmentEarth’s Health in Sharp Decline, Massive Study Finds大规模研究发现：地球的“健康”每况愈下The report card has arrived from the largest ever scientific Earth analysis, and many of the planet’s ecosystems are simply not making the grade.有史以来对地球进行的最大规模的科学分析结果表明，地球上的许多生态系统都达不到标准。

The UN-backed Millennium Ecosystem Assessment Synthesis Report found that nearly two-thirds of Earth’s life-supporting ecosystems, including clean water, pure air, and stable climate, are being degraded by unsustainable use.由联合国主持的《千年生态系统评估综合报告》指出，由于不可持续的使用，地球上将近三分之二的用来维持生命的生态系统（包括干净的水源、纯净的空气以及稳定的气候）正遭受破坏。

Human has caused much of this damage during the past half century. Soaring demand for food, fresh water, timber, fiber and fuel have led to dramatic environmental changes, from deforestation to chemical pollution, the report says. The already grim situation may worsen dramatically during the first half of the 21st century, the report’s authors warn.以上大部分的破坏都是人类在过去的半个世纪里造成的。

Teach Predictions for 20101. Finally, Apple Unveils the TabletOfficially, Apple has never said a word about making a tablet computer. Yet for months, everyone in tech has been talking and writing and arguing about the Apple tablet as if it's already here. The product has already received more press than most products that actually exist. Bloggers debate its faults and flaws, its strengths and Shortcomings--such is life in the weird and wonderful world of Apple. And this does not happen by accident. Apple orchestrates this stuff. It did the same thing with the iPhone, remember? For a year before the prodtict was unveiled, rumors circulated and fake prototype photos popped up all over the place. Ifs all about creating hype, and wrapping a product in a cloud of mystery and drama, so that by the time you do unveil it people are dying to buy it just tosee what all the fuss is about.The great thing about Apple, however, is that usually the products live up to the hype. Certainly the iPhone has. Arguably, it is the single most important tech product of the past decade. Will the tabletbe as profound? We think it will be. Amazon's Kindle has pioneered the market for a portable reading device. But Kindle is far from perfect. Our bet is that Apple enters this space the way it did with the iPod and iPhone: it lets others do the pioneering work and make all the mistakes, then comes along with a product that blows the predecessors away. Better design. Better build quality. Better service. And a user interface experience that’s light years ahead of everyone else's on the planet.2. Murdoch Pulls out of GoogleThe biggest, most powerful, and once-thought-to-be indestructible print media outlets have arrived at their moment of reckoning. For a decade, the likes of the Los Angeles Times, The Washington Post, and The New York Times (not to mention innumerable other oudets), have offered up their best work on a silver, online platter-- for free. Look at where it got them. The first is in jeopardy of closing up shop, the Post has shuttered its domestic bureaus, and the Gray Ladys just eliminated some 100 newsroom jobs, the second such move in two years. Enter Rupert Murdoch, theoutspoken Aussie head of News Corp whose empire spans from the Times of London to the most august business publication in the United States, The Wall Street Journal. For months now, he has been ranting about the free consumption of news online. His radical idea? Murdoch wants to stop Google from indexing his sites, and he wants Microsoft to pay for the privilege instead. In other words, he wants someone to pay for the stuff his journalists produce.A chorus of bloggers is crying that the old man's thinking cuts against the force of history--namely, that information wants to be free, and that any future-minded company ignores that fact at its peril. Techdirt says the news baron is a hypocrite. Boing Boing says Murdoch's threat to block searches and shroud his sites with paywalls is nothing more than a bluff. Think again. This isn't a doddering old coot who doesn't get the Web. Murdoch is a savvy business-man who just might lead an industry back into the reality-based community. With billions in cash on hand, he can afford short-term losses as his properties experiment with strategies that do not involve the essential untenability of giving the product away. And once he proves that a news publication can poke Google in the eye and survive, others will follow suit. After all, if they don't, Murdoch may be the only one left standing.3. Malw Disrupts FacebookWhen it comes to malware, the law of gravity is this: the bad guys go where the money is. That's why threats to computer users have evolved from viruses to botnets and phishing attacks--each iteration is more likely to produce profit. How does a piece of malware make money, exactly? In a number of ways, from rifling through your files for bank-account information and credit-card numbers, to turning your computer into a spam factory. The follow-the-money rule also helps explain why there aren't many threats for *Mac computers. They may have some security advantages over PCs, but mostly their market share isn't big enough to be worth malware creatorg time. )It follows that as we conduct more of our lives online, malefactors will follow us there. And where is the biggest action on the Web today? Facebook, which just signed up its 350 millionth user and shows no sign of slowing down. Facebook has seen malware before; the latest threat is an especially virulent edition of the "Koobface" worm that has bedeviled the social network for months. It's going to get worse from here. Facebook has a team of smart engineers dedicated to keeping malicious activity off the site, but with the network ballooning in size, they'll need to redouble their defenses in even greater proportion.4. Starbucks Will Stalk YouPrivacy is so passe. We've become addicted to broadcasting our lives to the world, and the mobile phone is our greatest enabler. That's especially true now that GPS is a standard feature. And today's hottest startups are racing to become the ankle bracelet of choice, doing everything they can to track our every move and indulge our shout-it-from-the-rooftops exhibitionism. Location-aware services like Foursquare, which awards points every time you check into a bar or restaurant, have become staples among the early-adopter crowd. Meanwhile, Twitter6 has added geolocation to its service, meaning each tweet is like a thumbtack on the map of your daily travels. Rumors have it that Facebook, with its 350 million users, is heading in the same direction. It's only a matter of time before advertisers follow. You can almost hear the screams of joy coming from marketing departments nationwide: soon companies will be able to target their ad campaigns based not just on who you are, but where you are. Passing by a Starbucks? Your phone just offered you 10 percent off a peppermint latte!5. Movie Downloads Stall Blu-rayBlu-ray may have won the war with its rival, HD-DVD---but does anyone care? While consumers were waiting for the two formats to duke it out--nobody wanted to plunk down several hundred bucks on a losing technology--they discovered that downloading movies to their homes has matured into a great way to watch their favorite titles. A Harris Interactive poll in June found that only 7 percent of consumers without Blu-ray players planned on buying one in the next year. Whafs holding back a format that everyone agrees is showstoppingly gorgeous to watch? Money is a big part of it, of course. Getting video over the Internet through iTunes9 or Amazon Video on Demand can be much cheaper than purchasing physical copies. Sometimes the value is truly insane: all it costs to binge out on seasons one, two, and three of Friday Night Lights is $ 8.99. That's the price of the cheapest monthly subscription to Netflix, which allows unlimited streaming of some shows and movies to your PC, or to your big screen if you own an Xbox 360, PlayStation 3, newer TiVo, or a similar device,Yes, a Blu-ray disk provides better quality picture and sound. But as Wired magazine argued in a recent cover story, consumers are enjoying a "Good Enough Revolution" : we're nuts about MP3s, even if they sound kind of crappy, and we can't watch enough YouTube clips, even though they're pixellated and choppy. The feverish pursuit of top quality is no longer our only concern. Sometimes convenience matters more.6. Your Phone Replaces Your WalletDuring its most recent pledge drive, the popular public-radio program This American Life followed a familiar script, exhorting its users to chip in $10, $ 5, even just $1, to help pay for its weekly broadcast. The pitch wasn't new, but one of the payment methods was instead of heading to your computer and entering your credit-card information, you could simply send $ 5 to the show via text message. Long promised, never realized, mobile payments will finally take off in the U. S. in 2010. Already the sector is a beehive of activity, with companies like Zong and mPayy enabling cus tomers to pay for online purchases with only a phone number. Obopay, another mobilepayments company, received $ 35 million from Nokia in 2009, and it will have a wide rollout on that company's phones. Perhaps the best sign that the sector is poised for takeoff is that Twitter creator and tech superstar Jack Dorsey has set his sights on it. His new company, Square, launched in December, allows merchants to accept credit-card payments with cell phones. True, Square doesn't untether us from plastic just yet, but it's only a matter of time before "Cash or credit?" becomes "Cash or cell?"7. Facebook Goes PublicAt only 25 years old, Facebook's Mark Zuckerberg has turned his donn-room idea into a global empire. Might he identify with Alexander the Great, who wept at the size of his dominion because there were no more lands left to conquer? Not just yet: he can still take the company public. In November, the social-networking company took a major step toward that event by announcing that it was creating two classes of stock: one class suitable for sale in an initial public offering, and one that is vested with 10 times the voting power. An IPO under those conditions would flood the company with cash while keeping control firmly in Zuckerbergs hands. If that sounds familiar, it's because the strategy is the same one used by Google before it went public in 2004. Zuckerberg is as cutthroat and super-ambitious as he is socially awkward that is to say, very--and he would stand to become an actual billionaire, not just a virtual one. His Personal wealth has yo-yo'd in line with various private valuations of his company over the years. Facebook also announced this year that it is cash-flow positive, and a successful IPO would cement the site as a viable business, while archrival Twitter stillscrambles for a business model.8. Twitter Use FlatlinesTwitter is almost synonymous with explosive growth. But there are signs that 2009's darling of the Internet has already begun to level off, a reversal that would have seemed impossible not long ago. In February 2oo9, Nielsen Online reported that Twitter's 7 million unique visitors constituted more than 1,000 percent growth in just a year's time. Ashton Kutcher, after beating CNN to the million-follower mark in a neckand-neck race, began blasting past later milestones with ease. (He's now at 4.1 million followers. ) And when Oprah Winfrey embraced the service in April, Twitter's popularity simply hockey-sticked.There were skeptics all along-- Nielsen also reported last spring that 60 percent of Twitter users failed to return after one month but excitement about the new mediurm's potential made them easy to dismiss. Now the data have become difficult to ignore. Twitters U. S. traffic actually declined from September to October, according to a range of measures. We're by no means Twitter haters--here's proof--but it seems clear that the service is in for a period of modest performance, as sign-ups of new users are measured against better estimates of existing users who neglect their accounts. One of the things that has made Twitter so successful is its wide-open API; ironically, that same transparency can provide a reality check on the number of people who have let their accounts go totally dormant who began tweeting during the Oprah bubble, but turned out to be making just a short stop at the birdbath.9. Microsoft Pushes Out Steve BallmerBallmer's 10th anniversary as CEO of Mierosoft arrives in January, but ifs hard to imagine he'll be celebrating. Mierosoft stock has dropped by nearly 50 percent on his watch, lagging not just other teeh eompanies but even the Dow Jones industrial average. Distracted by the Windows Vista fiasco, Ballmer has missed every big new tech market of the past decade. Google won the race for Internet search and keyword advertising. Apple won in MP3 players and online music sales, and now holds the high ground in mobile phones, while Windows Mobile fades away. Microsoft's Zune music player is a dud. Bing, Microsoft's search engine, will never catch Google. Ballmer is said to be a brilliant guy, but he got a black eye for the way he blundered and blustered and finally botched an attempted acquisition of Yahoo. He's a screamer and a bit of a bully--not the easiest guy to work for. If Microsoft were any other company, this guy would be in trouble. But the catch is, Ballmer was put into the job by Microsoft founder Bill Gates, and the two have been pals since their undergraduate days at Harvard. If Gates wants to get rid of Ballmer, he' 11 have to craft some kind of graceful exit that lets his buddy save face. Another problem: there's no heir apparent on the management team. Nevertheless, investors must be getting restless. Soon they'll start calling for a shake-up.10. Google Faces Antitrust SuitThe Feds are already looking at Google on a variety of fronts. Its deal with book publishers has drawn scrutiny. In 2009 it was hassled by the Federal Trade Commission over possible anticompetitive connections because it shared two board members with Apple, a situation that got resolved when Google CEO Eric Schmidt quit Apple's board, and Arthur Levinson, an Apple board member, quit the Google board. Regulators freaked out again when Google tried to make a search partnership with Yahoo. Supposedly the Feds were ready to bring charges, but then Google walked away from the deal.After facing this scrutiny in the past year, Google has launched a kind of ongoing publicity campaign, wooing the media and hoping to convince people that it isn't really a big bad company. It likes to say that it's operating in a highly competitive field and that its users can leave with the click of a mouse. But the fact is, Google handles two thirds of all searches in the United States. Whether that can legally be defined as a "monopoly" and whether Google can be shown to have abused its powerful market position remains to be seen. But regulators here and/or in the European Union will find Google so tempting a target that they will not be able to resist bringing a case to find out.Addicts of the Information AgeAmong everybody from our leaders to our teenagers, no habit is spreading faster than being connected 24/7 via a smart phone.[2] Its penetration in the U.S. is estimated at 18%, and it seems that everywhere you turn, people are using their smart phones in new ways and in new places. Samsung recently estimated that it expects 500 million global smart-phone users by 2012. Actual phone calls are becoming extinct compared with handheld texts and email messages--whoever thought people would prefer typing to talking? But the evidence appears to say they do.[3"] This has also given rise to a group of people--the top 10% of smart-phone users--who just can't stop. They are the smartphoniacsI, the true addicts of the information age.[4] Here are five tell-tale2 traits of Smartphoniacs :Do they take their smart phones with them when they get up from the table to go to the restroom---and do they take an awful lot of trips there?Do you receive messages from them while you know they are driving (increasingly being harmed in state after state), or at midnight on Saturday night?Do they come up with excuses in the middle of a conversation to pull out their smart phone--something like "let me jot something you said down so I don't forget it", and then sneak a look at all their messages?Are they suffering from sprained or elongated thumbs?Do they openly use their smart phones in inappropriate places, such as first dates, at Rosh Hashanah4 or Christmas dinner, in hospital delivery rooms, or on job interviews?[5 ] If your "friend" fits four out of five of these, then he or she is a smartphoniac. If he fits only two or three of them, he is just another typical user who stays connected on the street, in meetings and at the movies.[6] As these devices pop up everywhere, there has been a recent spate of articles about smart-phone "manners"--as if using your phone when your boss, or your mother, is talking to you is just a matter of poor training on their part. I don't think your boss or your mom ever said "go ahead, text while I'm talking to you". So it's just not a matter of manners. Ifs much more the result of a deeper disconnect anxiety, an irrepressible fear that you will miss something if you put it away.[7] I once worked with a candidate for Senate who emailed me from the podiums during a debate. Many 'CEOs communicate today primarily from their smart phones. Hillary Clinton and Barack Obama used them on the campaign trail, while John MeCain didn't.[8] The famed red phone to call the Russian premier in the event of a national security emergency could now be replaced by a red smart phone. Imagine if the world's top leaders were all connected bysmart phones and they communicated directly and frequently about issues of mutual concern. It would revolutionize diplomacy.[9] But Smartphoniacs are an eclectic mix of the successful and powerful, busy professionals, teenagers and college students. All of them commtmicate incessantly.[10] In Korea, more than three in 10 youths who carry mobile phones are said to be addicted. In Germany, there are an estimated 380,000 texting addicts—folks who withdraw from the very family and friends their machines were supposed to connect them to. While there hasn't been a formal study of Smartphoniacs in America, we know that between the second quarter of 2007 and the second quarter of 2008, the North American smart-phone market grew 78.7%. About 139.3 million smart phones were sold world-wide last year, and half of U. S. smart-phone users report using their devices more today than they did just three months ago.[11] Last month, the National Texting Championship award and its $ 50,000 grand prize went to a 15-year-old who texts 500 times a day. A recent poll found that 42% of teens can text with their eyes closed. And based on other studies on the intensity of smart-phone use, we can guess that Smartphoniacs skew male, affluent and well-educated. Not since the television has any invention changed the lifestyle habits of Americans more than the smart phone. The recent movie Seven Pounds detailed the guilt of an executive who caused a fatal car crash because he emailed while driving.[12] To be sure, there are forces calling for temperance7. Some people refuse to date people who use smart phones. Many parents just say no. Legislators are getting into the act to protect public safety. But for the most part, Americans of every age and stage are wrapping themselves in apps, chcks and instantaneous communication as part of a social network. And some small but significant percentage of this group is going to take a one-way slide to the bottom, where the compulsion to use their smart phones is so strong that they can only hope their batteries last long enough to text a cry for help.[13] We're not far away from Smartphoniacs Anonymous or Mothers Against Smart Phones. We've been through this with TV, the Intemet and videogames. In the end it all works out and we successfully integrate them into our lives, even though we are never again the same. At least with smart phones, with all their usage counters, we will be able to tell who has recovered from the binges.。

Intelligent Power Supply英文With the rapid development of electronic technology, application field of electronic system is more and more extensive, electronic equipment, there are more and more people work with electronic equipment, life is increasingly close relationship. Any electronic equipment are inseparable from reliable power supply for power requirements, they more and more is also high. Electronic equipment miniaturized and low cost in the power of light and thin,small and efficient for development direction. The traditional transistors series adjustment manostat is continuous control linear manostat. This traditional manostat technology more mature, and there has been a large number of integrated linear manostat module, has the stable performance is good, output ripple voltage small, reliable operation, etc. But usually need are bulky and heavy industrial frequency transformer and bulk and weight are big filter.In the 1950s, NASA to miniaturization, light weight as the goal, for a rocket carrying the switch power development. In almost half a century of development process, switch power because of is small volume, light weight, high efficiency, wide range, voltage advantages in electric, control, computer, and many other areas of electronic equipment has been widely used. In the 1980s, a computer is made up of all of switch power supply, the first complete computer power generation. Throughout the 1990s, switching power supply in electronics,electrical equipment, into the rapid development. In addition, large scale integrated circuit technology, and the rapid development ofswitch power supply with a qualitative leap, raised high frequency power products of, miniaturization, modular tide.Power switch tube, PWM controller and high-frequency transformer is an indispensable part of the switch power supply. The traditional switch power supply is normally made by using high frequency power switch tube division and the pins, such as using PWM integrated controller UC3842 + MOSFET is domestic small power switch power supply, the design method of a more popularity.Since the 1970s, emerged in many function complete integrated control circuit, switch power supply circuit increasingly simplified, working frequency enhances unceasingly, improving efficiency, and for power miniaturization provides the broad prospect. Three end off-line pulse width modulation monolithic integrated circuit TOP (Three switch Line) will Terminal Off with power switch MOSFET PWM controller one package together, has become the mainstream of switch power lC development. Adopt TOP switch lC design switch power, can make the circuitsimplified,volume further narrowing, cost also is decreased obviousiy.Monolithic switching power supply has the monolithic integrated, the minimalist peripheral circuit, best performance index, no work frequency transformer can constitute a significant advantage switching power supply, etc. American Pl (with) company in Power in the mid 1990s first launched the new high frequency switching Power supply chip, known as the "top switch Power", with low cost, simple circuit, higher efficiency. The first generation of products launched in 1994 represented TOP100/200 series, the second generation product is the TOPSwitch - debuted in 1997 П .The above productsonce appeared showed strong vitality and he greatly simplifies the design of 150W following switching power supply and the development of new products for the new job, also, high efficiency and low cost switch power supply promotion and popularization created good condition, which can be widely used in instrumentation, notebook computers, mobile phones, TV, VCD and DVD, perturbation VCR, mobile phone battery chargers, power amplifier and other fields, and form various miniaturization, density, on price can compete with the linear manostat AC/DC power transformation module.Switching power supply to integrated direction of future development will be the main trend, power density will more and more big, to process requirements will increasingly high. In semiconductor devices and magnetic materials, no new breakthrough technology progress before major might find it hard to achieve, technology innovation will focus on how to improve the efficiency and focus on reducing weight. Therefore, craft level will be in the position of power supply manufacturing higher in. In addition, the application of digital control IC is the future direction of the development of a switch power. This trust in DSP for speed and anti-interference technology unceasing enhancement. As for advanced control method, now the individual feels haven't seen practicability of the method appears particularly strong, perhaps with the popularity of digital control, and there are some new control theory into switching power supply.(1) The technology: with high frequency switching frequencies increase, switch converter volume also decrease,power density has also been boosted, dynamic responseimproved. Small power DC - DC converter switch frequency will rise to MHz. But as the switch frequency unceasing enhancement, switch components and passive components loss increases, high-frequency parasitic parameters and high-frequency EMI and so on the new issues will also be caused．(2) Soft switching technologies: in order to improve the efficiency of non-linearity of various soft switch, commutation technical application and hygiene, representative of soft switch technology is passive and active soft switch technology, mainly including zero voltage switch/zero current switch (ZVS/ZCS) resonance, quasi resonant, zero voltage/zero current pulse width modulation technology (ZVS/ZCS - PWM) and zero voltage transition/zero current transition pulse width modulation (PWM) ZVT/ZCT - technical, etc. By means of soft switch technology can effectively reduce switch loss and switch stress, help converter transformation efficiency.(3) Power factor correction technology (IC simplifies PFC). At present mainly divided into IC simplifies PFC technology passive and active IC simplifies PFC technology using IC simplifies PFC technology two kinds big, IG simplifies PFC technology can improve AC - DC change device input power factor, reduce the harmonic pollution of power grid.(4) Modular technology. Modular technology can meet the needs of the distributed power system, enhance the system reliability.(5) Low output voltage technology. With the continuous development of semiconductor manufacturing technology, microprocessor and portable electronic devices work more and more low, this requires future DC - DG converter can providelow output voltage to adapt microprocessor and power supply requirement of portable electronic devicesPeople in switching power supply technical fields are edge developing related power electronics device, the side of frequency conversion technology, development of switch between mutual promotion push switch power supply with more than two year growth toward light, digital small, thin, low noise and high reliability, anti-interference direction. Switching power supply can be divided into the AC/DC and DC/DC two kinds big, also have AC/AC DC/AC as inverter DC/DC converter is now realize modular, and design technology and production process at home and abroad, are mature and standardization, and has approved by users, but the AC/DC modular, because of its own characteristics in the process of making modular, meet more complex technology and craft manufacture problems. The following two types of switch power supply respectively on the structure and properties of this.Switching power supply is the development direction of high frequency, high reliability, low consumption, low noise, anti-jamming and modular. Because light switch power, small, thin key techniques are changed, so high overseas each big switch power supply manufacturer are devoted to the development of new high intelligent synchronous rectifier, especially the improvement of secondary devices of the device, and power loss of Zn ferrite (Mn) material? By increasing scientific and technological innovation, to enhance in high frequency and larger magnetic flux density (Bs) can get high magnetic under the miniaturization of, and capacitor is a key technology. SMT technology application makes switching power supply has made considerable progress,both sides in the circuit board to ensure that decorate components of switch power supply light, small, thin. The high frequency switching power supply of the traditional PWM must innovate switch technology, to realize the ZCS ZVS, soft switch technology has become the mainstream of switch power supply technical, and greatly improve the efficiency of switch power. For high reliability index, America's switch power producers, reduce by lowering operating current measures such as junction temperature of the device, in order to reduce stress the reliability of products made greatly increased．Modularity is of the general development of switch power supply trend can be modular power component distributed power system, can be designed to N + 1 redundant system, and realize the capacity expansion parallel. According to switch power running large noise this one defect, if separate the pursuit of high frequency noise will increase its with the partial resonance, and transform circuit technology, high frequency can be realized in theory and can reduce the noise, but part of the practical application of resonant conversion technology still have a technical problem, so in this area still need to carry out a lot of work, in order to make the technology to practional utilization.Power electronic technology unceasing innovation, switch power supply industry has broad prospects for development. To speed up the development of switch power industry in China, we must walk speed of technological innovation road, combination with Chinese characteristics in the joint development path, for the high-speed development of national economy to make the contribution.中文智能开关电源随着电子技术的高速进展，电子系统的应用领域愈来愈普遍，电子设备的种类也愈来愈多，电子设备与人们的工作、生活的关系口益紧密。

科技英语原文及简单翻译How ASIMO WorksIntroduction to How ASIMO WorksWant a robot to cook your dinner, do your homework, clean your house, or get your groceries? Robots already do a lot of the jobs that we humans don't want to do, can't do, or simply can't do as well as our robotic counterparts.Honda engineers have been busy creating the ASIMO robot for more than 20 years. In this article, we'll find out what makes ASIMO the most advanced humanoid robot to date.The Honda Motor Company developed ASIMO, which stands for Advanced Step in Innovative Mobility, and is the most advanced humanoid robot in the world. According to the ASIMO Web site, ASIMO is the first humanoid robot in the world that can walk independently and climb stairs.Rather than building a robot that would be another toy, Honda wanted to create a robot that would be a helper for people -- a robot to help around the house, help the elderly, or help someone confined to a wheelchair or bed. ASIMO is 4 feet 3 inches (1.3 meters) high, This allows ASIMO to do the jobs it was created to do without being too big and menacing.ASIMO's Motion: Walk Like a HumanHonda researchers began by studying the legs of insects, mammals, and the motion of a mountain climber with prosthetic legs to better understand the physiology and all of the things that take place when we walk -- particularly in the joints. For example, the fact that we shift our weight using our bodies and especially our arms inorder to balance was very important in getting ASIMO's walking mechanism right. The fact that we have toes that help with our balance was also taken intoconsideration: ASIMO actually has soft projections on its feet that play a similar role to the one our toes play when we walk. This soft material also absorbs impact on the joints, just as our soft tissues do when we walk.ASIMO has hip, knee, and foot joints. Robots have joints that researchers refer to as \degrees of freedom.\A single degree of freedom allows movement either right and left or up and down. ASIMO has 34 degrees of freedom spread over different points of its body in order to allow it to move freely. There are three degrees of freedom in ASIMO's neck, seven on each arm and six on each leg. The number of degrees offreedom necessary for ASIMO's legs was decided by measuring human joint movement while walking on flat ground, climbing stairs and running.ASIMO also has a speed sensor and a gyroscope sensor mounted on its body. They perform the tasks of:? ?sensing the position of ASIMO's body and the speed at which it is moving relaying adjustments for balance to the central computer These sensors work similarly to our inner ears in the way they maintain balance and orientation.ASIMO also has floor surface sensors in its feet and six ultrasonic sensors in its midsection. These sensors enhance ASIMO's ability to interact with its environment by detecting objects around ASIMO and comparing gathered information with maps of the area stored in ASIMO's memory.To accomplish the job our muscles and skin do in sensing muscle power, pressure and joint angles, ASIMO has both joint-angle sensors and a six-axis force sensor.Unless you know a lot about robotics, you may not fully grasp the incredible milestone it is that ASIMO walks as we do. The most significant part of ASIMO's walk is the turning capabilities. Rather than having to stop and shuffle, stop and shuffle, and stop and shuffle into a new direction, ASIMO leans and smoothly turns just like a human. ASIMO can also self-adjust its steps in case it stumbles, is pushed, or otherwise encounters something that alters normal walking.In order to accomplish this, ASIMO's engineers had to find a way to work with the inertial forces created when walking. For example, the earth's gravity creates a force, as does the speed at which you walk. Those two forces are called the \inertial force.\ground, called the \posture has to work to make it happen. This is called the \zero moment point\(ZMP). To control ASIMO's posture, engineers worked on three areas of control:? ?Floor reaction control means that the soles of the feet absorb floor unevenness while still maintaining a firm stance.Target ZMP control means that when ASIMO can't stand firmly and its body begins to fall forward, it maintains position by moving its upper body in the direction opposite the impending fall. At the same time, it speeds up its walking to quickly counterbalance the fall.?Foot-planting location control kicks in when the target ZMP control has been activated. It adjusts the length of the step to regain the right relationship between the position and speed of the body and the length of the step.ASIMO's Motion: Smooth MovesASIMO can sense falling movements and react to them quickly; but ASIMO's engineers wanted more. They wanted the robot to have a smooth gait as well as do something that other robots can't do -- turn without stopping.When we walk around corners, we shift our center of gravity into the turn. ASIMO uses a technology called \predictive movement control,\Intelligent Real-Time Flexible Walking Technology or I-Walk, to accomplish that same thing. ASIMO predicts how much it should shift its center of gravity to the inside of the turn and how long that shift should be maintained. Because this technolgy works in real time, ASIMO can do this without stopping between steps, which other robots must do.Essentially, with every step ASIMO takes, it has to determine its inertia and then predict how its weight needs to be shifted for the next step in order to walk and turn smoothly. It adjusts any of the following factors in order to maintain the right position:? ? ? ?the length of its steps its body position its speedthe direction in which it is steppingWhile reproducing a human-like walk is an amazing achievement, ASIMO can now run at speeds up to 3.7 miles per hour (6 kilometers per hour). In order to qualify as a true running robot, ASIMO must have both feet off the ground for an instant in each step. ASIMO manages to be airborne for .08 seconds with each step while running. Honda engineers encountered an entirely new set of challenges while trying to give ASIMO the ability to run. They gave ASIMO’s torso a degree of freedom to aid in bending and twisting so that the robot could adjust its posture while airborne. Without this ability, ASIMOwould lose control while airborne, possibly spinning in the air or tripping when landing.In order to make turns smoothly while running, the engineers enhanced ASIMO's ability to tilt its center of gravity inside turns to maintain balance and counteractcentrifugal force. ASIMO could even anticipate turns and begin to lean into them before starting the turn, much like you would if you were skiing or skating.ASIMO如何工作介绍如何工作。
