So here, what I'd like you to do is identify the correct radial probability distribution plot for a 5 s orbital, and also make sure that it matches up with the right number of radial nodes that you would expect.

这里，你们要辨认,哪个是５ｓ轨道的正确概率分布，并且确保它和你们,预期的节点数相符合。

Now what we do is to record the number of those action potentials in some period of time, and plot them on the graph below.

现在，我们要做的是记录,在一定时间内可能做出的动作，在图表中设计出来。

So, if language seems exhausted because it's always preceding you, everything has always already been said, there's no new plot to be had, the world is full of stock phrases, how do you use them to embody an experience that seems fresh to you?

所以，如果因语言，在你之前就存在，而它就显得枯竭，如果一切都已经被说过，如果已没有新的情节可供创造，如果世界一直充满陈腔旧调，你如何能够用它们,呈现出一个崭新的体验？

It looks like we hit zero, but we actually don't remember that we never go all the way to zero, so there's these little points if we were to look really carefully at an accurate probability density plot, And then, for example, how many nodes do we have in the 3 s orbital?

但其实没有，记住，我们永远不会到零,如果我们，在概率密度图上,非常细致的看这些点的话,它永远不会到零，在3s轨道里，有多少个点呢？，2个，正确？
