当它被设置为对数或线性类型时，如果你修改音量距离函数，类型将自动更改为自定义衰减。

If you try to modify the volume distance function when it is set to Logarithmic or Linear, the type will automatically change to Custom Rolloff.

度量的距离函数是基于概率事件结构达到一致的最长因果集束链的长度。

The distance function of the metric is based on the length of the longest bundle chain in probabilistic event structures.

So, essentially we're just breaking it up into two parts that can be separated, and the part that is only dealing with the radius, so it's only a function of the radius of the electron from the nucleus.

所以本质上我们把它写成,两个可分离的部分，这部分，只与半径有关，它仅仅是，电子,到核子距离的函数。

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。

So, we can use Coulomb's force law to think and it does that, it tells us the force is a function of that distance. But what it does not tell us, which if we're trying to describe an atom we really want to know, is what happens to the distance as time passes?

来考虑这两个粒子之间的,它告诉我们力随距离的函数关系,但它不能告诉我们，而我们如果要描述,原子又非常想知道的是,距离随时间的变化时怎样的？
