VOA慢速英語(yǔ)：有史以來(lái)第一次：科學(xué)家使用激光冷卻液體

University of Washington researchers say they used a laser to turn hot water into cool water.

Five engineers from the university are the first in the 50-year history of the laser torefrigerate liquids under normal conditions with light beams.

在對(duì)于研究激光長(zhǎng)達(dá)50年的歷史中，華盛頓大學(xué)的5位工程師首次利用激光光束在日常條件下冷卻液體。

The group used a simple approach to the experiment. Lasers are known for producing hot temperatures. The University of Washington says they "essentially ran the laser phenomenon inreverse."

該團(tuán)隊(duì)使用簡(jiǎn)單的方法來(lái)進(jìn)行實(shí)驗(yàn)。眾所周知，激光器會(huì)生產(chǎn)高溫。華盛頓大學(xué)表示他們?cè)谘芯康倪^(guò)程中成功地對(duì)激光進(jìn)行了反向利用。

The discovery has a future in the computer and medical fields. Computer interiors could be cooled by lasers. In a medical laboratory, individual cells could be cooled to see how they react. visit the website www.chinavoa.com to get more information!

"Few people have thought about how they could use this technology to solve problems because using lasers to refrigerate liquids hasn't been possible before," said researcher Peter Pauzauskie.

研究人員Peter Pauzauskie 說(shuō)：“很少有人會(huì)想到使用這種技術(shù)來(lái)解決問(wèn)題，因?yàn)榧す饫鋮s液體在這之前是不可能的。”

The cool laser concept can also be used in manufacturing, telecommunications or national defense.

使用激光進(jìn)行冷卻這一概念也可用于制造、電信或國(guó)防。

The group has an interest in hearing from businesses or scientists who may have every day applications for the cool laser.

該團(tuán)隊(duì)現(xiàn)在對(duì)其他那些申請(qǐng)用激光冷卻的科學(xué)家和企業(yè)的想法非常感興趣。

The findings were published this month in the Proceedings of the National Academy of Sciences.

本月，這項(xiàng)研究結(jié)果在美國(guó)國(guó)家科學(xué)院院刊出版。
