2012年五大科技突破

SHELLEY DUBOIS 2013-01-07
2012年是個(gè)科技豐收年。下面五大科技創(chuàng)新涵蓋了材料、生物、電子和汽車等領(lǐng)域,可能很快就會改變整個(gè)商業(yè)世界的面貌和人們的日常生活,。

????汽車革命夢想成真

??? 對于汽車來說,,現(xiàn)在已經(jīng)是個(gè)新時(shí)代了,。戴伊說:“我認(rèn)為,,我們即將迎來汽車行業(yè)的一次重大轉(zhuǎn)型?!彼a(bǔ)充說,,這次轉(zhuǎn)型已經(jīng)醞釀了一段時(shí)間,但是現(xiàn)在,“材料,、導(dǎo)航,、汽車電子系統(tǒng)和動(dòng)力系統(tǒng)的重大革新真的同時(shí)到來了,?!?/p>

????汽車廠商們必須密切關(guān)注電動(dòng)汽車、插入式混合動(dòng)力轎車,、完全混合動(dòng)力轎車以及其它節(jié)能技術(shù)領(lǐng)域的消費(fèi)者趨勢,。經(jīng)歷了幾乎整整一個(gè)世紀(jì)的內(nèi)燃發(fā)動(dòng)機(jī)時(shí)代后,如今汽車廠商正在改造汽車的動(dòng)力系統(tǒng),,利用新型動(dòng)力技術(shù),,生產(chǎn)老百姓消費(fèi)得起的環(huán)保汽車。

????2011年末,,汽車消費(fèi)者已可在全美范圍內(nèi)買到2012款雪佛蘭沃藍(lán)達(dá)(Chevy Volt)混合動(dòng)力轎車,。今年,,日產(chǎn)公司(Nissan)又在美國推出了聆風(fēng)(Leaf)的完全電動(dòng)版本,。

????動(dòng)力系統(tǒng)并不是汽車業(yè)唯一的創(chuàng)新機(jī)會,今天的汽車已經(jīng)變得越來越像電腦了,。不過戴伊表示:“也不要放棄內(nèi)燃發(fā)動(dòng)機(jī),。當(dāng)你覺得一項(xiàng)行業(yè)主流技術(shù)即將被淘汰的時(shí)候,也正是這一技術(shù)獲得最大進(jìn)步的時(shí)候,?!?/p>

????Out of my dreams, into my (improved) car

????It's a new world for cars. "I think we're at the cusp of quite a significant transformation in the auto industry," Day says. This transformation has been building for some time, he adds, but now, "major innovations in materials, navigation, on-board electronic systems and drivetrains are really starting to come together."

????Automakers must keep an eye on consumer trends around electric vehicles, plug-in hybrids, full hybrids, and cars equipped with other mileage-extending technology. And after about a century of powering vehicles with good old combustion engines, car companies are tweaking the drivetrain -- the system that makes a car move -- and using this updated tech to build affordable cars.

????At the end of 2011, car buyers could get the 2012 Chevy Volt hybrid car nationwide. This year, Nissan released the fully electric version of the Leaf in the United States.

????Not that drivetrains are the only opportunity for automotive innovation; indeed, cars are becoming more like computers every day. "Don't give up on the internal combustion engine either," Day says. "An industry's technology improves the most just when you think it's being put out of business."
