我们已经有了一个阿尔法粒子源。

So, what we've got here is a source of alpha particles.

他证实了，阿尔法粒子就是氦核。

And there he was able to identify the alpha particle as the helium nucleus.

这和阿尔法粒子类似。

This is the analogy to the alpha particle.

And, so the experiment was to bombard the foil with these alpha particles, and that measure what happens to them.

因此用这些阿尔法粒子,去轰击金箔，将会发生什么事情呢。

First of all, the majority of the alpha particles were transmitted through the screen, OK, majority, vast majority.

第一点，大部分的阿尔法粒子,全都从屏幕穿透过去了，嗯，大部分的，绝大部分的。

OK, so tiny fraction, tiny fraction of alphas, tiny fraction of incident alphas, tiny fraction of incident alphas deflected through large angles.

这一小部分，极少的阿尔法粒子，极小部分的入射阿尔法粒子，小部分的入射阿尔法粒子,以大角度偏转。
