所以，丁醇释放的能量比同样重量的乙醇多，在特性是它更像直链烷烃分子；它也不像乙醇那么容易吸水。
That gives butanol more energy for a given mass and makes it more alkane-like in its properties; nor does it absorb water as readily as ethanol.
我们的大脑，比同等重量的肌肉，要多消耗20倍的能量。 大脑会说：“先生，请多给我一些肉。”
Our brain — which uses about 20 times as much energy as the equivalent amount of muscle — piped up and said, "Please, sir, I want some more."
近几年转向了锂离子电池，可以做的小很多，有着超高的重量能量比。
That's shifted in recent years to lithium-ion batteries, which can be made much smaller, with a superior weight-to-energy ratio.
试验研究表明在相同重量下，设计合理的复合材料对称元件可以比金属元件吸收更多的冲击能量。
Most experimental research had demonstrated that well-designed composite symmetrical elements could absorb more impact energy than metal elements with same weight.
