这个角度是φ，它是从z轴偏转的角度。

That's phi is the angle downwards from the z axis.

我们需要计算偏度系数来衡量偏转的程度。

We need to calculate the coefficient of skewness to measure the degree of deflection.

为妨碍'的'和'使'后缀偏转的增加机会。

Increased chances for 'of blocking' and 'of deflecting' suffix.

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。

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。

The first, which I just stated, is that the deflection of that negative particle was just far and away more extreme, much, much larger than that of the positive particle. The other assumption that he made here is that the charge on the two particles was equal.

为了这么做，他又做了更多的观察,首先，像我之前已经说了，测到的负电粒子,偏转要远远,大于正电粒子,另外一个他做了一个假设。
