一个带负电的粒子之间，的作用力,这本质上就是库伦力，我们可以把它，描述成一个引力。

So, if we think about the force that occurs between a positively and a negatively charged particle, what we have is essentially a Coulomb force, so we can describe this as a force of attraction.

在电极之间用一个电压同时会使块上胶囊的粒子上产生一个位移，这样就改变了它的颜色。

Applying a voltage between the electrodes causes a simultaneous shift in the particles in all the capsules in a block, thus changing its colour.
