He could divide all of that by the absolute value of the charge of the positive particle, all over the mass of the positive particle.

他可以把这整个，除以正电粒子的，电荷绝对值除以，正电粒子的质量。

A proton is an elementary particle of matter that possesses a positive charge.

质子是带正电荷的物质的基本粒子。

《柯林斯英汉双解大词典》

It will be a particle with a positive charge and a positive mass.

它将是一个带着正电荷和正质量的粒子。

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。

In addition, the standard model says the particle also should have positive parity, which is a measure of how its mirror image behaves.

However, if the new particle doesn't have positive parity, then things get a lot more interesting at least from a physicist's point of view.

WSJ: New Data Boosts Case for Higgs Boson Find

The latest CERN data suggests that the newly discovered particle appears to have no spin and positive parity.
