托福閱讀資料之心跳也能發(fā)電

　　The human heartbeat could be used to power an ipod after scientists developed a tiny chip which uses the body's own movement to generate power.

　　如果科學(xué)家們能改進一種用人體自身活動發(fā)電的微型芯片，那么將來ipod就可以靠心跳來充電了。

　　Scientists hope that as the nanotechnology used in the chip evolves, it could lead to electronics which don't require batteries or mains power.

　　科學(xué)家們希望，隨著在芯片內(nèi)所運用的納米技術(shù)不斷進步，以后可以生產(chǎn)出不需要電池或系統(tǒng)供電的電子產(chǎn)品。

　　Hailed as a milestone, it can use tiny movements such as the pinch of a finger to generate power.

　　這被認為是里程碑式的進步，它將使諸如手指輕輕一捏這樣的細小動作也能產(chǎn)生電能。

　　The team, presenting their findings at the National Meeting &Exposition of the American Chemical Society, have used it to power LCD displays and diodes, as well as to transmit a radio signal once its generated power has been stored.

　　研究這一項目的科學(xué)團隊在美國化學(xué)會年會上展示了自己的研究成果，他們用芯片為液晶屏幕和兩極真空管充電，并用充完電的機器傳播廣播信號。

　　The latest device is thousands of times more powerful than its predecessors, allowing scientists to take the technology out of the lab for the first time.

　　科學(xué)家們最新研究出的裝置比以前的那些強大了數(shù)千倍，這使他們第一次可以將這項技術(shù)帶出實驗室。

　　The technology works by using zinc oxide nanowires, which generate electricity when strained or flexed.

　　它運用了氧化鋅納米線，氧化鋅納米線在被拉緊或收縮時都會發(fā)電。

　　This mean virtually any body movement - from walking to a heartbeat - can generate power.

　　這就意味著從步行到心跳，幾乎任何一個身體動作都能產(chǎn)生能量。

　　Five nanogenerators working together produced about 1 micro ampere output current at 3 volts about the same voltage generated by two regular AA batteries.

　　5個納米發(fā)電機同時工作可以產(chǎn)生1微安培3伏特的輸出電流，與2節(jié)普通的5號電池所產(chǎn)生的電壓差不多。

　　Dr Zhong Lin Wang, of Georgia Institute of Technology said: "While a few volts may not seem like much, it has grown by leaps and bounds over previous versions of the nanogenerator.

　　佐治亞理工學(xué)院的王中林教授說：“也許這么點電壓看上去很不起眼，但是比起過去的納米發(fā)電機已經(jīng)有了飛躍。”

　　"Additional nanowires and more nanogenerators, stacked together, could produce enough energy for powering larger electronics, such as an ipod or charging a cell phone."

　　“如果把更多的納米線和納米發(fā)電機放在一起，就足以為更大的電子產(chǎn)品提供電能，比如為一臺ipod或一部手機充電。”

　　"Our nanogenerators are poised to change lives in the future. Their potential is only limited by one's imagination."

　　“納米發(fā)電機將改變?nèi)祟愇磥淼纳睿鼈兊臐摿χ挥邢氩坏?，沒有做不到。”
