If you have an experiment and the outcome of the experiment is a number, then a random variable is the number that comes from the experiment.
如果你有一个试验,这个试验的结果是一个数,那么相对应的随机变量,指的就是这个试验结果所对应的那个数
Yeah, so for example, you get exposed to-- before there was a vaccine your brother or sister had chickenpox, and so you got exposed to chickenpox naturally through your contact with them.
举个例子来说,如果你生活在这样的环境里,兄弟姐妹们还没接种疫苗就得了水痘,而你通过与他们相接触,在自然情况下接触到了水痘病毒
Wouldn't a later writer have cleaned up this ancestral record if this were in fact something composed at a later period? Also, he notes that the representation of inter-ethnic relationships in the patriarchal stories does not accord with the reality of a later period.
后世的作者难道不会把祖先不光彩的记录抹去吗,如果事实上这故事是后来创作的话?同时,他还提出,宗族故事中所展示的种族间关系,与后世的现实是不相一致的。
And in either case if we first talk about constructive interference, what again we're going to see is that where these two orbitals come together, we're going to see increased wave function in that area, so we saw constructive interference.
在任何情况下,如果我们首先讨论相长干涉的话,我们同样会看到,当这两个轨道靠拢的时候,我们看到这个区域有波函数增加,所以我们看到的是相长干涉。
If you just compare the pattern between a typical control and Mike, you can see that Mike is missing a lot of the responses in the very centre of the visual field.
如果将控制组和迈克的模型相比较,大家能够看出,迈克的视野中心缺少许多反应。
If I asked you what magazines you read, it turns out people who are right wing read right wing magazines, people who are left wing read left wing magazines, because people don't as a rule enjoy getting information that disconfirms what they believe in.
如果我问你们,你们看什么杂志,我会发现右翼的会看右翼的杂志,左翼的会看左翼的杂志,因为一般来说,人不喜欢接收到,与他们信奉的相矛盾的信息。
So you should remember that any time we combine 2 s orbitals, what we're going to find is if we constructively interfere those two orbitals, we're going to form a bonding orbital.
你们要记住,任何时候我们组合两个2s轨道,我们会发现,如果我们把它们相长叠加,我们会得到一个成键轨道。
In contrast, if we have destructive interference, what we're going to form is a sigma 2 s star, and what does the star designate?
相反,如果我们是相消干涉,我们会形成sigma2s星,星代表什么?
If the forms are not physical objects, then Socrates thinks it follows they can't be grasped.
如果型相不是物理实体,那么苏格拉底认为他们不可被认知
If seeing things that participate in the forms remind me of the forms, it's got to be because I've met or been acquainted directly with the forms before.
如果我看到了,一种型相的物体能让我想到这型相本身,那么我之前一定直接见过,或者对那型相本身很熟悉
One of the things that I didn't mention before is that when you get this primary response and then the secondary response, if you looked at the antibodies that are generated during the primary response, again we're only looking at antibodies that bind to the particular antigen or vaccine that we have used for the priming.
还有一点我之前没有提及,当你获得初次免疫,以及再次免疫之后,如果你仔细观察抗体,观察那些在初次免疫中生成的抗体,这次我们同样只是观察抗体,那些与我们在初次免疫中所用到的,特定抗原或疫苗相结合的抗体
If you want to write a function that describes this line here, it's pressure as a function of volume related to each other with this constant.
如果要写出描述这条等温线的方程,它的压强和体积,就通过常数C相联系起来。
Whereas if the phases where mismatched, you would not get bonding.
如果两个相位不相符合,就不能成键。
If you compare the s orbital with the bottom lobe, these have a different sign so they're going to destructively interfere.
如果你们比较s轨道和下面这叶,它们正负号相反,所以它们相消干涉。
So, I want to contrast that with another concept that seemed to be opposing ideas, and that is thinking about not how far away the most probable radius is, but thinking about how close an electron can get to the nucleus if it's actually in that orbital.
我要将它和另外一个,看起来相反的概念相比较,我们不是考虑,最可能半径离原子核有多远,而是考虑如果电子在那个轨道上,能多接近原子核。
And we are invited to imagine the fate of, again finding ourselves in the bodies of other creatures and, if you can imagine this, this is because you are imagining what you are as separate from the body that you reside in.
在这里,作者再次邀请我们去想象,我们自己被困在其他动物身体里的场景,如果你能想象如此场景,那是因为你将自己当做了,与所依肉体相分离的心理实体
You can see if we combine the s with the top lobe of the p, they're going to constructively interfere because they have the same sign.
你们会看到如果我们把s轨道和p轨道的上叶结合,它们是相长干涉,因为它们负号是相同的。
I couldn't have told you, for example, if we look at a phosphate group, that that's going to be incredibly important in DNA, that it's also an incredibly important group when you're dealing with proteins and whether you're turning the function of a protein on or off.
怎么和化学反应相联系起来的,更不记得其它我更不感兴趣的规律,我不能告诉你,如果我们看磷酸盐,它们对于构成DNA十分重要,也是构成蛋白质的重要组份,它是否能打开或关闭一个蛋白质的功能。
