It will depend on the density of your points (see a few words on density), but a good recommendation is to start off with the simple range approach and then move up to the tier approach if need be.

这取决于点的密度(参见关于密度的简要说明)，但是我们建议首先采用简单的范围方法，然后在需要的时候提升到层方法。

DBSCAN is a spatial clustering algorithm based on density.

DBSCAN是一个基于密度的聚类算法。

The reason in our radial probability distributions we start -- the reason, if you look at the zero point on the radius that we start at zero is because we're multiplying the probability density by some volume, and when we're not anywhere 0 from the nucleus, that volume is defined as zero.

在径向概率密度里，我们开始,如果你们看半径的零点，我们从零点开始,因为我们用概率密,度乘以体积,而当我们，在离核子很近的地方,体积是，所以我们会在这里。

s And if we go ahead and superimpose the 3 s on top of the 3 p, you can see that the 3 s actually has some bit of probability density that gets even closer to the nucleus than the 3 p did.

如果我们继续将,重叠到3p上面，你们会看到3s事实上,有一点概率密度,距离原子核更近,比3p轨道。

You can see down here its affect on cholesterol levels: that the bad fats raise the LDL levels, the low-density lipoproteins levels, that's not good for you.
