通过原子上能级与光子频率带隙边缘的相对位置或者光子态密度，可以抑制或增强原子的自发辐射。

Spontaneous emission can be totally suppressed or strongly enhanced depending on the relative position of the resonant frequency from the edge of the photonic band gap and the photonic mode density.

普朗克—爱因斯坦关系式用光子的频率来描述每个光子的能量。

The Planck–Einstein relation describes the energy of each photon in terms of the photon's frequency.

So this means that we can go directly from the energy between two levels to the frequency of the photon that's emitted when you go between those levels.

这意味着我们可以直接,从两个能级的能量得到它们之间,跃迁发射出光子的频率。

Any frequency can't have an energy, you have to -- you don't have a continuum of frequencies that are of a certain energy, it's actually punctuated into these packets that are called photons.

任何频率不能有个能量,你必须要-对某一个能量上,你不会有连续的频率,光子实际上分立的存在。

So, the take-home message is whether you have three photons or 3,000,000 photons that you're shooting at your metal, if you're not at that minimum frequency or that minimum energy that you need, nothing is going to happen.

所以，这里表明的信息是,无论是向金属发射3个光子,还是300万个光子,如果没有达到所需的最低频率,或者最小能量,什么事情都不会发生。
