So, we know now that we have charged particles. Are these negatively or positively charged based on this evidence?

弯曲的角度,现在我们知道,阴极射线是带电粒子,但从这个实验？

Basically what he did is he took a very thin metal foil and he bombarded it with charged particles.

简单的说他做的工作是,用一张非常薄的金属箔,然后用带电的粒子轰击它。

So, what we're looking at here is the force when we have two charged particles, one positive one negative -- here, the nucleus and an electron.

我们现在研究的是,一正一负俩个带电粒子之间的,作用力-在这里。

PROFESSOR: Yeah, that's right. So, what we have here, cathode rays we now know are negatively charged particles. And, in fact, he named these negatively charged particles. Does anyone know what he named them? No, not electrons - very good guess. He named them corpuscles.

学生：负电，教授：是的,我们现在知道，阴极射线是带负电的粒子,实际上他还给这些,带负电的粒子去了一个名字,有谁知道叫什么吗？

And what was known about alpha particles at the time is that they were these charged particles and that they were very heavy.

当时对alpha粒子的理解,是它们是带电的而且非常重，有谁知道的,比Rutherford时代的多吗。

So, what he could conclude thus far was that this was really consistent with the Plum Pudding model. All of his heavily-charged alpha particles were going right through this thin layer of gold atoms.

和布丁模型是吻合的,所有的重alpha粒子,都穿过金原子,你们也许会觉得,他可以就此。
