Finally, for the spectral radius of a graph with a cut vertex, we give an inequality concerning the spectral radius of the graph and its subgraphs.

最后，对于有割点的图的谱半径给出一个与子图的谱半径有关的一个不等式。

We can graph out what this is where we're graphing the radial probability density as a function of the radius.

我们可以，画出它来，这是径向概率密度，作为半径的一个函数图。

So, the example that we took on Monday and that we ended with when we ended class, was looking at the 1 s orbital for hydrogen atom, and what we could do is we could graph the radial probability as a function of radius here.

周一我们,最后讲到了，粒子是氢原子１ｓ轨道，我们可以画出,这幅径向概率分布曲线。

And what here is just a graph of the 1 s wave function going across some radius defined this way, and you can see that the probability - well, this is the wave function, so we would have to square it and think about the probability.

这里是,1s波函数,沿这个方向的图，你们可以看到概率,这是波函数，所以我们可以把它平方,并想成是概率。
