useful energy

常見(jiàn)例句

Getting useful energy from formate is now the simplest way known for any life form to get its fuel, though it relies on the absence of oxygen.
從甲酸鹽中獲取所需的能量是目前最簡(jiǎn)單的維持生命方式，雖然它依賴於無(wú)氧的環(huán)境。
To generate useful energy, plants have evolved very sophisticated "nano-machinery" which operates with light as its energy source and gives a perfect quantum yield of 100%.
爲(wèi)了産生有傚能，植物進(jìn)化出了異常精密的“納米機(jī)器”，它以光爲(wèi)能量來(lái)源，光能轉(zhuǎn)化率達(dá)到了完美的100％。
The building of a real-life version of "Maxwell's demon" – which can turn information into useful energy – might mean that future nanomachines can be powered purely by information.
建造“麥斯威爾妖”的現(xiàn)實(shí)生活版本——它可以把信息轉(zhuǎn)變爲(wèi)有用的能量——意味著未來(lái)的毫微級(jí)計(jì)算機(jī)可能純粹地依靠信息來(lái)作爲(wèi)動(dòng)力。

So, in this class we'll be talking about energy a lot, and it's often useful to draw some sort of energy diagram to visualize the differences in energy that we're discussing.
所以，這堂課我們會(huì)討論很多,關(guān)於能量的問(wèn)題，討論時(shí)，畫(huà)能級(jí)圖來(lái)使能量差別,形象化常常是很有用的。

Now these quantities were useful because you could relate them. The slope of changes, with respect to volume or temperature of the energy with respect to quantities that you understood, that you could measure.
去得到這些量,這些量很有用，而且你們已經(jīng)知道了，怎麼把它們相互聯(lián)系起來(lái),像這種比例形式的量，能量比上溫度或躰,或其它你們懂的可以測(cè)量量。
