And I want to stress this, we're going to come back to it later on in the term, so the way I'd like you to think about it for now, is that somewhere in the machine, there's a big space that contains all possible values.
我想要强调一点,我们在晚些时候,还会回头来讲这一点,因此现在,我需要你们形成这么一个观点,就是在计算机的某处,有一个包含了所有可能值的,很大的空间,好。
But they're accountable and we can list all possible values when they're discrete and form a probability weighted average of the outcomes.
但随机变量是离散的话,我们可以把所有的可能值列出来,然后算出加权平均值
So, we end up with a total of six electrons that are possible that have that 2 p orbital value.
所以我们最后,总共得到了6个电子,在所有可能的“2p“轨道值中。
Right. It's a slight lie, it doesn't have all possible values, but you get the idea. It has, if you like, intellectually, all possible values.
我撒了个小谎,这个空间并没有包含所有的可能的值,你们懂的,理性点说,如果你喜欢,我这么说的话,它包括了所有可能的值。
You can find values of all of these if you look at your Table of Constants.
如果你在你的常数表中仔细找一下,可以找到所有这些常数的值。
I'm assuming all the components are positive.
我现在已经假设所有值都是正的
And here d, of course, can take the values from plus three down to minus three.
而d层,当然,能够包括从+3到-3的所有值。
The green line is the building costs and you can see that building costs, since 1890, in real terms-- everything is corrected for inflation -have gone up a little bit since 1890, but not a whole lot.
绿线表示了建筑成本,你可以看到建筑成本,自1890年来,以实际值计算,所有的数据均进行了通胀修正,从1890年开始有一点点上涨,并非是大幅度上涨
For an angular node, we're just talking about what the l value is, so whatever l is equal to is equal to the number of angular nodes you have.
对于角向节点,我们其实就是在讨论l,的值是多少,因此不管,l,的值等于几,它就等于你所有的角向节点的数目。
And when we talk about l it is a quantum number, so because it's a quantum number, we know that it can only have discreet values, it can't just be any value we want, it's very specific values.
当我们讲,l是一个量子数时,因为它是量子数,我们知道,它只能去分立的值,它不能取到所有的数,它取一些确定的数。
