energy cost

基本解释

The next factor is the energy cost of running, which is the equivalent to miles per gallon in an automobile.
第二个因素是运动能量消耗，相当于汽车每英里消耗汽油加仑量。
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，散步和跑步时的能量消耗与腿的长度有关。
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.
对于许多陆地动物来说，从髋关节到地面的距离可以推测出活动时的能量消耗，其准确度达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.
但实际上，在一个轨道上放两个电子,确实会亏损一点能量，因为，当你加入更多电子，引起更大的排斥能,这显然会消耗能量，这不是我们想要做的，但是在这种情况下我们不得不做，结果这一影响，超过了增加一个,原子序数所得到的能量。

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.
现在我们在同一个，p，轨道上放了两个电子，这没问题，我们可以这样做，这样不会亏损太多能量。

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.
木质纤维素原料生物转化生产纤维乙醇需要使用大量的水和蒸汽,从而使过程能耗和废水排放显著增加,大幅度增加了加工成本。
