Just like we see destructive interference with water waves or with light waves, we can also see destructive interference with orbitals.

就像我们看到水波,和光波的相消干涉，我们也可以看到轨道的相消干涉。

And so there are only two kinds of waves that can exist on this violin string, standing or traveling.

由于这只有两种波,可以存在在这条弦上，驻波或行波。

Satan's described initially here as the wind god Orion, a classical figure who vexed or tossed the waves of the Red Sea, ; just as Satan is rousing and inspiring his fallen host of angels; but Milton continues to complicate the simile.

撒旦在这里最初被比作风神猎户，这是一个在红海上呼风唤浪的古典形象，就像撒旦在他的天使随从面前充满了威严;,但是弥尔顿接下来又使这个比喻复杂化了。

But first, I just want to remind you when we're talking about molecular orbital theory, this is treating electrons as waves, so what we're actually able to do is either constructively or destructively combine atomic orbitals to form molecular orbitals.

但首先，我要提醒你们,当我们讨论，分子轨道理论的时候，我们把电子看作是一种波,所以我们可以相长叠加,或者相消叠加这些原子轨道来组成分子轨道。

So, for example, we have this average level, and then it can go high where we have the peak, or it can go very low. We can also discuss sound waves, so again it's just the periodic variation of some property -- in this case we're talking about density, so we have high density areas and low density areas.

例如这是平均位置，在峰的位置水位高，在谷水位低，我们也可以,讨论声波它也是某种,量的周期变化，在这里我们,讨论的是密度,我们有高密度区和低密度区。
