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。
-
Alpha particles are these helium nuclei, and they are the result of radioactive decay.
阿尔法粒子是氦核，它们是放射性衰变的产物。
-
So, what we've got here is a source of alpha particles.
我们已经有了一个阿尔法粒子源。
-
A tiny fraction of the incident alpha particles were deflected through large angles.
极小部分的入射的阿尔法粒子,发生大角度的偏转。
-
And there he was able to identify the alpha particle as the helium nucleus.
他证实了,阿尔法粒子就是氦核。
-
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。
-
This is the analogy to the alpha particle.
这和阿尔法粒子类似。
-
He shot alpha particles which have a charge of plus two.
他入射的阿尔法粒子带有两个正电荷。
-
On the other hand, when it came to penetrating solids, penetrating solids, the alpha radiation was poor at penetrating solids, whereas the beta radiation was very good at penetrating solids.
另一方面，当研究穿过固体的时候，嗯，穿过固体，会发现阿尔法射线很难穿过固体，然而贝塔射线,很容易穿过固体。
-
Majority of alphas transmitted, that means, when I use the term transmitted that means passing through in the direction that they were originally traveling, transmitted and some deflected through small angles.
阿尔法粒子大部分穿过去了，当我用穿透这个词,是说按照原来的方向,穿透过去,包括有些小角度的偏离的穿透。
-
Rutherford used alpha particles.
卢瑟福用的是阿尔法粒子。
