We know what an electric field is, it's just a space through which a Coulomb force operates.

我们知道，电场不过，是库仑力的作用空间。

We can use the Coulomb force law to explain this where we can describe the force as a function of r.

我们用库伦定律解释它，力作为距离r的函数，让我们考虑一下。

The conventional inter-particle force model, including van der Waals force, Coulomb force and image force, could not explain these interaction behaviors.

受力分析表明，包含范德华力、静电库仑力和电像力的传统颗粒间作用力模型不能解释这种相互作用行为。

So, remember when we talk about Coulomb force, what's holding the nucleus and the electron together, there's 2 things we need to think about.

还记得我们在讨论库仑力的时候，提到是什么将原子核与电子束缚在一起时，有两点需要考虑。

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.

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。
