I mean we can, we can sort of understand why OK, the total energy, if we measure it, we measure a process which is not reversible.

例如我们易于理解为什么，当试图测量一个不可逆系统的总能量，给出的或许。

The total energy of the system, which we are going to get from postulate number four, which says the energy of the electron, which is the energy of the system, is the sum of the kinetic and the potential energy.

这个系统的总能量，也就是我们将从第四个假设中算出的能量，也就是电子运动产生的能量，也就是整个系统的能量，是动能和位能的总和。

So, therefore, we can rewrite our equation in two ways. One is just talking about it in terms only of energy where our kinetic energy here is going to be equal to the total energy going in -- the energy initial minus this energy of the work function here.

所以我们可以把方程,写成两种形式，一个是,只考虑能量，动能等于总的,入射能量-初始能量减去,功函数的能量，我们如果想解决,比方说，我们想知道。

Let this represent the total energy of the incident electron.

让这个来表示入射电子的,总能量。

And thanks to Professor Hess, I can now say that the total energy delta H In other words, delta H formation of sodium chloride should be independent of paths.

感谢道盖斯教授，我们可以认为，这整体过程,氯化钠的化合能,与路径无关。

And we know that n describes the total energy, that total binding energy of the electron, so the total energy is going to be equal to potential energy plus kinetic energy.

我们知道，n是描述总能量的，电子总的结合能，所以总能量，等于,势能加动能。

So, what we can do is figure out what we would expect the binding energy of that electron to be in the case of this total shielding.

完全屏蔽的案例中,期望的电子结合,能再次记住,结合能物理上来说是。
