So, what we would expect is that there is a relationship between intensity in kinetic energy because it was understood that however intense the light was, if you had a more intense light, it was a higher energy light beam.

光强和能量之间,应该有一定的关系,因为在我们的理解中,不管光强是多少，光的强度越大,光束能量越高。

The next thing that they wanted to look at was the actual intensity of the light and see what the relationship of intensity to kinetic energy is.

下一而他们要研究的是光的强度,看一下光强和能量之间的,关系是怎样的，我们预期。

So if I worry about energy I have a pretty good chance of extracting out these heat capacities, right, and I don't have to worry about exactly which path and I can really mix things up.

而能量与热容有密切的关系,从能量就可以就算出这两个热容，我不需要考虑到底是哪一条路径,可以随意计算。

You can see low voltage, low energy, high voltage, high energy. It is a linear function.

你会看到，低电压，低能量，高电压，高能量，这是种线性关系。

The other thing that we know, which is what we were just discussing when we were going through the table is how this all relates to energy.

另外一个我们知道的事情就是，我们看这张图表的时候,我们讨论了,它和能量之间的关系。

That is, it gives us the relationship between energy and work and heat.

热力学第一定律阐述了,能量，功和热之间的关系。

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。

And, as you know, Einstein made many, many, many very important contributions to science and relativity, but he called this his one single most important contribution to science the relationship between energy and frequency and the idea of photons.

于这些波包里，你们也知道，爱因斯坦在科学和相对论上,做出了非常非常非常多的贡献,但它把这个叫做他对科学,最重要的贡献，就是能量和,频率之间的关系以及光子的概念。
