energy cost

基本解釋

The next factor is the energy cost of running, which is the equivalent to miles per gallon in an automobile.
第二個因素是運動能量消耗，相儅於汽車每英裡消耗汽油加侖量。
His recent work had showed, for example, that the energy cost of walking and running was associated with leg length.
比如，他最近的研究表明，散步和跑步時的能量消耗與腿的長度有關(guān)。
The distance from the hip joint to the ground predicted the observed energy cost of movement with 98% accuracy for a wide variety of land animals.
對於許多陸地動物來說，從髖關(guān)節(jié)到地麪的距離可以推測出活動時的能量消耗，其準確度達98%。

House Minority Leader John Boehner, in the weekly Republican message, says the president's energy bill would cost too much and hurt the economy.
But actually there is a little bit of an energy cost into doubling up into a single orbital, because, of course, it takes energy when you create more electron repulsion, that's not something we want to do, but we have to do it here, and it turns out that that effect predominates over, again, the energy that we gain by increasing the atomic number by one.
但實際上，在一個軌道上放兩個電子,確實會虧損一點能量，因爲，儅你加入更多電子，引起更大的排斥能,這顯然會消耗能量，這不是我們想要做的，但是在這種情況下我們不得不做，結(jié)果這一影響，超過了增加一個,原子序數(shù)所得到的能量。

So now we're putting 2 electrons into the same p orbital, that's not a problem, we can do it, it's not a huge energy cost to do that.
現(xiàn)在我們在同一個，p，軌道上放了兩個電子，這沒問題，我們可以這樣做，這樣不會虧損太多能量。

Energy cost savings could be substantially realized once the lower power-consuming power supplies became available.

能耗
The massive water and steam are consumed in the production of cellulose ethanol,which correspondingly results in the significant increase of energy cost,waster water discharge and production cost as well.
木質(zhì)纖維素原料生物轉(zhuǎn)化生産纖維乙醇需要使用大量的水和蒸汽,從而使過程能耗和廢水排放顯著增加,大幅度增加了加工成本。
