And, in fact there's a technique of analysis used today that's called Rutherford back scattering where people actually saw that this is a means of identifying the substance, the sample.

事实上这是现在用的一种分析技术,称作卢瑟福背散射,就是人们实际上看到的那样,这是鉴别物质样品的一种方法。

I'm going to give you the data set of the scattering angles of the atoms.

我会把,这些原子散射角的数据发给你。

I know table salt is white, but that is because you have power and you have multiple surfaces scattering, but a large crystal of sodium chloride is clear and colorless.

我知道食用盐是白色的，但这是因为你让它成了粉末,因为有了多个散射面，但是一个大的氯化钠晶体,是无色透明的。

For, as Rutherford has shown the assumption of the existence of nuclei, as those in question seems to be necessary in order to account for the results of the experiments on large angle scattering of the alpha rays.

因此卢瑟福,提出了原子核存在的假设，这些关于问题的假设对于,解释阿尔法粒子的,大角度散射是有必要的。

So, introduction, "in order to explain the results of experiments on scattering of alpha rays by matter, Professor Rutherford," and there is a footnote to the Rutherford model.

嗯，绪论，为了解释实验的结果,关于物质的alpha散射，卢瑟福说“,这儿有一个卢瑟福模型的脚注。
