And so, the radial probability density at the nucleus is going to be zero, even though we know the probability density at the nucleus is very high, that's actually where is the highest.
所以径向概率密度,在核子处等于零,虽然我们知道在,核子处概率密度很大,实际上在这里是最大的,这是因为。
They want to make sure that there's a significantly high probability-- sufficiently high probability-- that even if they get a bad draw and there are a lot policies that require paying out, that these reserves will satisfy.
他们想要确保,即使保险公司遇上严重事件,面临大量的保单赔付,他们仍然有充分能力,来应付这种状况,也就是说准备金必须足够多
So, this is an absolutely outstanding discovery, even though, if we think about it, what is the probability that this happened, how often did this happen?
0个alpha粒子,这绝对是一个,很了不起的发现,虽然我们仔细想想?
But Ian Hacking, being a good historian, thought that someone must have had some concept of probability going before even if they didn't quote it as a number the way-- it must have been in their head or in their idea.
但是这位优秀的历史学家伊恩·哈金认为,一定有人在更早时候就用过概率这个概念,即便他们没有用数字来表述,但他们一定有过类似的想法
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。
