Glucose has to get into cells, that's the main source of energy source that cells use, metabolism of glucose.

但葡萄糖又必须进入细胞,因为它是细胞能量的主要来源,即通过葡萄糖代谢产生能量

And that makes sense, too, because the positive three pulling on minus one has a tighter binding energy than positive one pulling on minus one.

而这也是有意义的，因为+3和-1的相互吸引,产生了比+1和-1的吸引,更强的能量。

By the same token the cult, Kaufman says, has no automatic or material power.

出于同样的原因，祭仪本身不能产生能量。

That's amazing, you can get atoms to smash atoms and create a chain reaction and create power-- that's a pretty amazing invention.

很惊人，你可以利用原子去做加速粒子,并产生连锁反应，然后创造能量-,那是个十分惊人的发明。

So we know we always want to have our systems in as low an energy as possible, so it makes sense that a bond would happen any time we got a lower energy when we combine two atoms, versus when we keep them separate.

我们知道我们总是希望使我们的系统,处于能量尽可能低的状态，因此就应该有化学键产生,一旦我们合并两个原子之后体系的能量变得更低，相较于分开时。

The total energy of the system, which we are going to get from postulate number four, which says the energy of the electron, which is the energy of the system, is the sum of the kinetic and the potential energy.

这个系统的总能量，也就是我们将从第四个假设中算出的能量，也就是电子运动产生的能量，也就是整个系统的能量，是动能和位能的总和。

So that's the important take-away message from this slide. If we think about these different types of lights, microwave light, if it's absorbed by a molecule, is a sufficient amount of frequency and energy to get those molecules to rotate. That, of course, generates heat, so that's how your microwaves work.

重要的信息，如果我们看看,这些不同种类的光，微波,如果被分子吸收，它的频率和能量可以,使分子转动,这当然的，会产生热量,这就是你们微波炉的工作原理。
