It's somewhat different when we're talking about the p or the d orbitals, and we won't go into the equation there, but this will give you an idea of what we're really talking about with this radial probability distribution.
当我们讨论p轨道或者,d轨道的时候会有些不同,我们那时不会给出方程,但它会给你们一个,关于径向概率,分布的概念。
OK, here we go, here we go, you see, I'm doing it down here, I can't see it, does that-- ah, I hear his sighs of relief, OK, good. There we go. Better. All right.
好,我们开始,大家可以看到,我在这里写这个程序,我看不见,这是不是-啊,我听到大家放松的叹气了,好,让我们开始吧,好多了,好。
So, when the voltage difference between the plates is zero, or when we just don't have the plates there at all, the cathode rays are not bent, they just go right in a straight line, and they can be detected on this screen.
拐弯来测试它们是否带电,当两板之间电压为零,或者根本就,没有这两个板时,阴极射线是一条直线,它可以在屏幕上。
But again for all our purposes, we don't have to go there.
但就我们的目的而言,我们不需要讨论这个。
There were words in there--they said something--of course, we cannot guarantee that they won't go up in value but historically they have always done it or something like that.
他们在文中吹嘘...当然,我们不能保证金币不会升值,但金币的历史行情趋势始终向上
If we can't take the city, we ought to go home and there's a lot of spirit that says we ought to go home. And so a dream comes to Agamemnon.
如果他们不能攻下城池,就得打道回府,并且很多人心里,都觉得应当回去,于是阿伽门农做了个梦
For our purpose I think we won't have to go there.
根据我们的目的,我们不需要讨论这个。
I think that at least for many of us, there is a sort of logical conundrum we go through and that is, if good people don't vote then we'll be in a bad world; so I have to vote to prove that good people vote, then maybe it will happen.
我想,至少对大部分人来说,必须面对一个逻辑上的难题,就是,如果好人不投票,那我们将会生活在坏人操纵的世界里,所以我必须要投票,来证明好人会投票,那未来的国家将会由好人掌控
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?
