So it's not a continuum of energy that we can have, it's only these punctuated points of energy that are possible.
我们得到的不是一个连续的能量，而是一些分立的可能的能量值。
-
Charge is quantized. And, secondly,he was able to measure the value of the elemental charge.
电荷是量子化的，第二，他能,测量出电荷基本的量值。
-
So since that's the easiest scenario, you can probably be sure it's not going to be too frequently that you're just given the energy, right, that might be too easy.
所以既然那是最简单的情况，你可以确信只给你提供能量值的,这种情况不太可能发生太多，对，因为那太简单了。
-
Well, the energy at infinity is zero -K and the energy in the ground state is minus K.
无限远处的能量值为,而基态能量值为。
-
Let's quantify the energy value. If you go through and solve for energy, you will get this equation.
我们来确定一下能量值，如果你试图寻找,解决能量问题，你能得到一个方程式。
-
And the closer it gets to the nucleus the greater the amount of energy, which means that you see this in the following manner.
而电子离原子核越近,能量值就越大，这就意味着你以下面的方式看到这些。
-
So, remember what we're talking about here is the amount of energy that's in each photon.
所以，记住我们这里谈论的是,每个光子的能量值。
-
Positive energy is repulsive, and negative energy is attractive.
正的能量值代表斥力，负的能量值代表引力。
-
What Einstein then clarified for us was that we could also be talking about energies, and he described the relationship between frequency and energy that they're proportional, if you want to know the energy, you just multiply the frequency by Planck's constant.
爱因斯坦阐述的是我们,也可以从能量的角度来谈论，他描述频率和能量之间的关系,是成比例的，如果希望知道能量值，你用普朗克常数乘以频率就可以了。
-
That is the ground state energy of atomic hydrogen.
同时也是氢原子基态的能量值。
-
So, the x axis is interatomic spacing, and the y axis is energy.
所以x轴是原子间距，而y轴是能量值。
-
And if we talk about electrons or photoelectrons, again we can describe it in terms of energy, we can talk about velocity, and from there, of course, you can figure out the energy from 1/2 m v squared, and actually we can also describe the electron in terms of wavelength.
如果我们谈论电子或者光电子，我们又可以从能量的角度来描述它，我们可讨论速率，从那里，当然，你可以计算1/2，m，v2得出能量值，而且事实上我们也可以,从波长的角度来描述电子。
