In other words, if we don't have to worry about entropy or volume equilibrium is achieved when energy is at a minimum.

换句话说，如果我们不担心熵,和体积的平衡,那么能量就得是最小的。

So what we're saying here is the incident energy, so the energy coming in, is just equal to the minimum energy that's required to eject an electron.

这里我们来讨论一下，入射能量正好等于,发射出一个电子所需要的最低能量的情况。

OK, so R minimum, the minimum separation occurs when the energy is at its minimum.

好的，所以R处是最小值，间距最小值出现在,当能量为最小的时候。

In some sense, that's one reason to associate this as a kind of energy, H just like mechanical energy u or enthalpy H, it's the minimum free energy state that is the equilibrium state under the relevant conditions.

在某种意义下，这是我们把这些物理量称为能量的原因，就像机械能U和自由焓，具有最小自由能的状态在特定的条件下,就是平衡态。

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。

Now this is a good place to start, because we are very familiar with ionization energy, we've been talking about it it's that minimum energy required to remove an electron from an atom.

现在这是一个开始下面内容的好地方，因为我们已经很熟悉电离能了，我们从很久以前就一直在讨论,它是从一个原子中,拿走一个电子所需要消耗的最低能量。

So if we're going to eject an electron using a minimum amount of energy, that's where it's going to come from.

因此，如果我们要用最少的能量,激发出一个电子，那这个电子一定是，2，p，轨道上的。
