weight per unit power

基本解釋

Besides efficiency, durability and reliability, the most important requirement for solar cells was how much power they could generate per unit of weight.
它在除了功效、耐久性和可靠度之外，最重要的要求是電池每重量單元能產(chǎn)生多少功率。
The high metabolic rate of small animals, for example, gives them sustained power and activity per unit of weight, but at the cost of requiring constant consumption of food and water.
例如，小動(dòng)物較高的新陳代謝率，以其體重的每單位計(jì)算均能賦予動(dòng)物以持續(xù)不斷的能量和活動(dòng)能力，但其代價(jià)是，要求它們不間斷地消耗水和食物。
