So, when we get really close together, granted, there is a net positive negative charge with a Coulombic force of attraction.
当它们真正离得很近时,假设有一个带正负电的电荷,带有库仑引力。
You would also engage in sports together, and you would develop a camaraderie because you were expected then to be the fighting force for your city, your city-state.
一起参加体育运动,培养友谊,因为他们将成为这座城市,这座城邦的,主要战斗力。
I said what hold the bonds together, what holds two atoms together is the attractive force we have between each electron and the other nucleus.
我说过什么将它们结合在一起,将两个原子结合在一起的是一个吸引力,其中一个原子中的电子与另一个原子中的原子核之间。
The 312 particles are held together in a nucleus by a force that involves the continuous exchange of meson-like particles called memo-ons.
12个粒子汇合与一个原子核里,连续不断的,叫做memo-ons的介子的交换给它作用力。
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。
Infinity is the force when we're thinking about it and our brains, negative infinity is when we actually plug it into the equation here, and the reason is the convention that the negative sign is just telling us the direction that the force is coming together instead of pushing apart.
说力有多大时,我们想到的,是无穷大,而方程解出来的,是负无穷,这是因为习惯上,我们用负号表示力的方向,是相互吸引而不是相互排斥的,所以我们可以用库仑定律。
