There's a sense of aliveness and energy, and in scientific terms everything is pure energy, so it's not that far-fetched.

有一种生机和能量，用科学的话来说，万物都是纯粹的能量，因此上面说法也不为过。

Yes. In fact, there is not enough energy in a single photon to go ahead and eject an electron from this zinc surface.

是的，事实上，这里的光子没有足够的能量,去从锌表面逐出一个电子。

And then the potential energy, the energy is stored here due to the coulombic force of attraction between the electron and the nucleus.

然后说势能,位能其实就是,由电子和原子核之间的库仑引力而形成的能量。

That is, you minimize potential energy and you see things falling under the force of gravity and so forthgoing to potential energy minima in conformance with this result.

换句话说，你使得势能最小化,然后发现我们关注的东西,在重力或者其他力的作用下下落,直到势能最小的地方,这和我们刚才的结果是一致的。

Spirit is merely a kind of bodily form of energy, and God at the beginning of time infused this energy into the entirety of the material world at the Creation.

灵魂不过是能量的一种物质形式，上帝在时间之始创世纪之际将这能量,注入到了整个物质世界之中。

So it's very difficult, but what I come down to is that you just have to place your energy on your breath, and every time you notice your awareness drifts to somewhere else, you have to recognize this drift and let it go.

因此这很难，但我总结的方法是,只需要把能量集中到呼吸上，每次注意力不集中,飘到别处时，要意识到意识的涣散，并放手不管。

With the United States quite isolated, not reaching out to Canada and Mexico, which is one thing we need to be doing for energy and economic reasons.

而美国则被孤立了，不和加拿大，墨西哥打交道，事实上这是我们现在该做的,为了能源问题和经济发展。

That is a maximum If you are sharing your time and energy during this period on Tuesday afternoons, or the arch-field don't work so think carefully about that.

让大家充分发挥自己的能力,如果每周二下午这段时间,你都有时间，精力也很充沛，就可以来上这门课，不过这样你就没时间参加实践活动了,所以请仔细考虑吧。

One major difference between electron affinity and ionization energy is that when we talked about ionization energy, remember ionization energy always has to be positive.

电子亲和能,与电离能之间最大的不同就在于,当我们提到电离能的时候，记得电离能总是正的。

As we go across the row what happens is that the ionization energy actually increases, and we can think about logically why it is that that's happening.

当我们沿着行,向右走的时候，可以发现电离能是逐渐升高的,我们可以从逻辑上思考一下为什么会这样。

If the bonding energy is very strongly negative, thermal energy isn't great enough to disrupt those bonds and allow those bonds to be broken and then have fluidity.

如果键能非常强，热能并不足以,打破这些化学键,破坏这些化学键,并使它们液化。

And the other thing to point out is that the energy that an anti-bonding orbital is raised by, is the same amount as a bonding orbital is lowered by.

另外一个要指出的事情是,反键轨道引起的能量升高，和成键轨道引起的能量降低是相同的。
