关键之处就在于速度，太阳能的传递几乎就在瞬间完成，所以很少能量以热的形式耗散掉。
Speed is the key –the transfer of the solar energy takes place almost instantaneously so little energy is wasted as heat.
我已经故意将这个箭头弄短，用来象征它变慢了，因为我们将证明它的质量没有变，只有它的能量改变了，也就是它的速度变了。
And I have purposely made the arrow shorter to indicate that it has been slowed because we are going to argue its mass didn't change, so the only way to change its energy is to change its velocity.
只是存在两个问题：它的储能比钴氧化物要低，而且导电率也较低，这限制了电池释放和存储能量的速度。
There were just two problems: it had a lower energy-density than cobalt oxide and suffered from low conductivity, limiting the rate at which energy could be delivered and stored by the battery.

能量被量子化，速度被量子化。
航天器的重量和轨道不同，所需火箭提供的能量和速度也各不相同，各种轨道与速度之间有一定的对应关系。
And the weight of the spacecraft orbit, the rocket needed to provide energy and speed varies, with a variety of track between the speed of a certain relationship.
这也就是PCR呈现负值会出现的情况。因为PCR负值的反应堆会自动限制穿越反应堆的中子数，所以会在短暂的能量增加后减慢增长速度。
This is where having a negative PCR is handy, because it automatically limits the number of neutrons flying through the reactor, so it damps itself down after a momentary power increase.
一兆焦相当于一个一吨重的物体以160公里/小时的速度撞一面墙产生的能量。
A megajoule is equivalent to the energy released when a one-tonne vehicle slams into a wall at 160kmh.

But typically sleep, appetite, energy, concentration come back to normal more quickly than that.
被消耗的能量(与鸟和飞机的速度相加的平方成正比)将大约是半吨的重物落下十英尺。
The energy to be dissipated (proportional to the square of the combined speed of bird and plane) would be more like half a ton being dropped ten feet.
由于物理定律规定能量守恒，其它恒星将获得同等巨大能量的推动，以惊人的速度飞走。
Since the laws of physics dictate that energy be conserved, the other star would gain an equally large energy boost, flying away at tremendous speed.
甲状腺是位于颈部的小腺体，控制新陈代谢以及身体将食物转化为能量的速度。
The thyroid is a small gland at the base of your neck. It controls your metabolism, the speed at which your body converts fuel into energy.

The thyroid is a small gland at the base of your neck.It controls your metabolism, the speed at which your body converts fuel into energy.
一旦你的身体知道如何快速跑，那在较低的速度下你需要的能量就更少，这样就减少了能量消耗，为后续阶段的跑步储存了能量。
Once the body knows how to run fast, at slower speeds, there is less effort required resulting in reduced energy expenditure which will assist in saving energy for the latter stages of any event.
