z So, this is what we find the actual z effective is for an electron in the helium atom.
所以这就是我们得到了实际有效的,对于一个氦原子的电子。
And, I will go through the actual line by line derivation not because I want to do derivations in class.
我们要仔细讨论实际的线,和推导出来的线,并不是我想在这节课做推导。
It turns out we won't really using it, needing to identify it on the graph so much in chemistry.
结果是我们不会实际运用它,那样我们在化学中,将要在图中识别它很久。
So, clearly, if we remove this barrier mixing takes place and obviously you know that that happens from lots of experience.
所以很明显,如果我们拿走隔板,气体混合就会发生,我们从大量的实际经验中就可以知道这些。
So now that we begin to have this ability to express strings in memory, to understand what they are, we can start to apply actually real-world algorithms to them.
现在我们开始用这个技能来在内存中表达字符串,来理解它们是什么,我们可以开始,我们可以对其使用实际的,现实生活中的算法。
So he stays with the idea that our de facto actual empirical desires are the only basis for moral judgment.
所以他始终认为,我们的实际欲望是道德判断的唯一基础。
So we would say the real interest rate equals the nominal rate-- approximately equals--the nominal rate minus the inflation rate.
我们可以推出实际利率约等于,名义利率减去通货膨胀率
And then we try and get our simulation to match the past, and hope that that will help it predict the future.
尝试让仿真程序能和这一部分实际数据相符,并且希望它能够帮我们对未来进行预测。
Now let's take this information and put it in the context of what a day's fat and calorie intake might be like.
现在让我们把刚才的知识运用到实际中,我们一天脂肪和卡路里摄入量是多少
Now, it gets complicated because there are some cases where we do allow stereotypes to play a role.
但实际情况没有这么简单,因为有时候我们确实允许,把刻板印象应用到生活中。
These things that we discovered were meant for a practical usage in ways that I will tell you about in a little while.
而这些我们发现的东西,在某些方面是有实际用途的,稍后我会提到
In fact in spite of the way we tell our story we actually changed the assignment.
尽管实验的过程是这样,可我们实际做了些改变。
It matters in how we take games through to the real world, and we're going to see more of this as the term progresses.
把博弈理论运用到实际是很重要的,本学期我们会不断学习类似的案例的
some modern drugs, chemotherapy drugs, as well as certain antibiotics, are hazardous to our hearing.
现今的某些药物,化疗制剂以及抗生素,也危害着我们的听力,以上所说的实际是。
Even Humbert will tell us so. Just a few pages later, on page 175, he talks about his journey: We had been everywhere. We had really seen nothing.
即使是纳博科夫也会这么告诉你们,只是几页之后,在175页,他谈到了这次旅行:,我们到处每一个地方,实际却一无所览。
Well let's talk about some mechanisms for using this and I'll start with a simple example of how one can detect a gene in a fluid, in a blood sample for example, where that gene is unknown.
我们来说说这项技术在实际应用中的机制,先从一个简单例子着手,如何在一个血样中,侦测是否存在某段基因序列,某段未知基因序列
So if we think about what we would do to actually write out this configuration, we just write the energy levels that we see here or the orbital approximations.
如果我们考虑我们所做的去,实际写出电子构型,我们只是写出我们看到的能级,或者是轨道近似就可以了。
And one of the things that was useful here is, that we actually know that the set of primitives that you want to use is very straight-forward.
这儿有一个很有用的东西是,我们实际知道你想用的,一系列基本类型是非常明显的。
So what I want to point out is 3d2 what we said now is that the 3 d 2 is actually lower in energy, so if we were to rewrite this in terms of what the actual energy order is, 3d2 4s2 we should instead write it 3 d 2, 4 s 2.
所以我们想指出的是,我们现在所说的是,实际上能量比较低,所以如果我们重新的,写出实际的能量顺序,我们应该写出。
When we're doing something that is interactive, we have to cut down on the detail of what we're doing because we can't support that in real time, but nonetheless there're lots of things we can do interactively.
当我们在做一些,互动性的项目时,我们需要减少,正在做的细节,因为在实际时间里,我们并没有足够时间支持它,但是还有很多其他东西,可以做得具有互动性。
It also is a good lesson in how difficult it is, and we'll talk about this in a subsequent class, to actually measure what people eat.
同样这能很好的说明,实际评价人们的饮食有多困难,我们下节课会讨论这个话题
Now, if you're an engineer, and you use the ideal gas law to design a chemical plant or a boiler or an electrical plant, you know, a steam plant, you're going to be in big trouble.
比如说锅炉,蒸汽机,我们会遇到一个大问题:,我们设计的机器将无法运作,因为对大部分实际气体。
Put that aside. Let's be more cynical here.
先不论这个理由,我们更实际一点。
We have a nice theoretical framework, but the application of the framework to the real data is hard and it ends up with politics underneath it all; that's just the real world.
我们有清晰的理论框架,但实际运用理论知识却困难重重,最终还是政治支配一切,这就是现实社会
So in reality, we need to take into account a little bit more, and in particular, we need to take into account the abilities of players to hit the ball accurately and/or hard.
所以分析实际情况时要深思熟虑,比如说,我们需要把罚球队员的,射门力度跟精准度考虑在内
We're just going to go through it and execute it a little bit. And then we'll move on and talk about how we'd actually make some of these measurements of delta H and compare
对吧?我们会讲完它并,实际应用一下,然后我们会,继续讲一下实际上我们,是怎样测量△H并与
Well, we play with it, the way I've been playing with it and compare the results to some set of real data.
好啦,我们来试一下我们之前也做过,就是用我们得到的结果和实际结果相对比。
Well, all of that might in fact be the goal but it's when you start hearing things like this hopefully that you at least start to grimace a little bit.
这是我们的目标,但实际上当你开始听到这样的事情,你可能开始愁闷苦脸了。
So we do, in fact, have a dependence on what the angle is of the electron as we define it in the orbital.
实际上当我们定义电子在这个轨道,它的波函数的确是和角度有关的。
Somewhere in memory, back to back to back or all of the strings and with them can we store actual words and phrases.
在内存某处,紧邻的或者所有的字符串,我们用它们可以存储实际的单词,和短语。
