There's a name for a thing like that in graphs.

有个专门的词可以形容你说的那个东西
It's the inflection point.

拐点
It's when the curvature changes from being this way,

就是当图线从这种形态
like Hooke's law,

就像胡克定律的那种图线一样
to being this way.

变到这种形态的时候所经过的那个点
So when the inflection points cross, then the chain pops.

当图线中出现拐点时链就断了
Okay, so force laws are going to make a lot of difference

所以力学定律对理解原子的行为至关重要
in how atoms behave, and if really knew the force law

如果我们把力学定律搞通透了
we'd be in a great position or understanding chemistry.

化学就会好理解得多
It snaps at the inflection point where it changes

链在拐点出现处断掉越过这点
from a direct to an inverse dependence on distance for force.

力的大小对距离的关系由正向变到反向
Okay, but what are bonds?

不过究竟什么是化学键呢
