常見例句雙語例句During the flow we manage to change some of the heat into mechanical energy.在 流傳 中 我們設(shè)法把部分熱變成機(jī)械能。For any given portion of air, the greater expansion ratio allows more energy to be converted from heat to useful mechanical energy meaning the engine is more efficient.對于任何給定的空氣部分，更強(qiáng)大的擴(kuò)展比允許更多的精力從熱量轉(zhuǎn)換為有用的機(jī)械能，這意味著發(fā)動機(jī)效率更高。diycnc.orgJames Joules The physicist James Joules, after we we call after him the unit of work was the first to demonstrate that heat energy and mechanical energy are really equivalent.物理學(xué)家，我們以他命名功的單位,他是第一個演示出,熱能和機(jī)械能相等的人。原聲例句You're always wasting energy into heat somewhere when you dochange that involves mechanical change.當(dāng)進(jìn)行與機(jī)械運(yùn)動有關(guān)的變化時,總會有能量變成熱量而被浪費(fèi)掉。麻省理工公開課 - 熱力學(xué)與動力學(xué)課程節(jié)選 返回 mechanical heat energy
