这些粒子主要是质子、电子和氦原子核,并且当他们与地球高层大气中的原子核碰撞,就能产生次级粒子簇射。
The particles are generally protons , electrons and helium nuclei and when they collide with nuclei in the Earth's upper atmosphere they can produce shower s of daughter particles.
如果大型强子对撞机LHC以7万亿电子伏全力运转,碰撞粒子的能量就相当于你吃0.00013微克糖得到的能量。
If the LHC was operating at its full 7 trillion electron volt capacity, the colliding particles' energy would equal what you'd get from eating 0.00013 micrograms of a candy bar.

If we get the pressure in there just right, we will allow for gas electron collisions and then we get the glow that ultimately was sent through the slits.
如果我们把气压设置在一个适当程度,把气体电子碰撞也算在里面,我们得到的炽热,最终将通过裂缝传送。
If we have too much gas in here, in other words, if the gas is at too high a pressure, the collisions with the gas molecules will consume the energy of the electrons and, again, we will see nothing.
假设这里有过多气体,换句话说,如果气体处在一个高压状态下,气体分子间的碰撞将会消耗,电子的能量,同样,什么也没有。
So what happens almost instantaneously after the collision, the electron up here falls back down.
所以在碰撞后,几乎同时,在这儿的电子又回去了。
