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。

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。

And this is exactly what happened with Marsden who discovered that when he shot the alpha particles at the gold foil he detected something on his detector that click, click, click went a little bit faster.

而对于Marsden来说,就是这样，他发现当他用alpha粒子,轰击金箔的时候，探测器哒哒哒得更快了,他发现一分钟。
