And what we predict as an energy difference between two levels, we know should correspond to the energy of light that's either emitted, if we're giving off a photon, or that's absorbed if we're going to take on a photon and jump from a lower to a higher energy level.

我们预测，两个能级之间的能量差，我们知道，它要么和发出的光有关,如果它发出光子的话，要么它吸收光子,从低能级跃迁到，更高能级上去。

As you may well have gleaned from your reading, the first books of the poem are particularly absorbed with the idea of forgetting, because more than any other part of Paradise Lost they display so ostentatiously the remarkable scope of Milton's own memory.

可能你们从阅读中也已经得知，这部诗的第一册,尤其表现了“遗忘“这一理念，因为相对于《失乐园》的其他部分,它们如此夸耀地展示了,弥尔顿自身记忆范围的宽广。

And there is a relationship here, and that is that the number of photons absorbed by the metal are related to the number of electrons ejected from the metal. So, in this figure here what I'm actually showing is these little sunshines, which let's say are each one individual photon.

这里有一个关系是，被金属吸收的光子,和被金属逐出的电子是相关的,所以，我展示的这个图,是这些小太阳，我们这里代指每一个独立的光子。
