PROFESSOR: All right. Good. So we can fully believe what our calculations were now, which is a nice thing to do.
教授:好了,我们现在可以,完全相信我们的计算结果了,多么美妙的一件事。
and then we're going to use the results of the experiment to write a lab report
然后我们根据实验结果来撰写实验报告,
And all this is, is saying that when you take a mixed second derivative, it doesn't matter in which order you take the two derivatives.
麦克斯韦关系的本质是,当你考虑混合的二阶导数时,求导的顺序不影响最后的结果,现在,我们利用这些关系。
It turns out that it's going to be a little bit different when we're talking about positive ions here.
结果是当我们讨论阳离子时,有一些不同。
Okay. Now ultimately what happens with this is that we begin to take this stream and organize it into different patterns.
好了,这最后的结果,是我们开始把一段无序的节拍流,组合成了不同的模式
And let's just run a couple of examples to remind you of what happens if we do this.
让我们跑一些例子来提醒,你我们这么做有什么结果。
And that's essentially what we saw people have more nucleus accumbens activation priority choice " they are more likely to choose that stock.
这就是我们得到的结果,在作出选择时,受试者的伏隔核活动越多,他们就越有可能选择“股票。
True, true, so I guess one result of our neglect in Afganastan was that the insurgence network has grown by leaps and bounds.
是,是,我想我们对阿富汗的忽略的一个结果就是,暴动组织急速地增长了。
But it turns out that as we'll see that functions absolutely take arguments, right?
但结果是我们将看到,函数绝对是有参数的,对不对?
The financial situation is not as bad as it was in the 1930s but it's getting bad and as a result we're starting to see proposals for big change.
现在的金融衍生工具已经不像当年那么拙劣了,但是它却开始走下坡路,所以最后的结果是,我们不得不准备着新的变革。
First, it's going to give us an outcome that we believe.
首先,它将给我们一个更可信的结果
What the clicker is is a little device that will allow you to enter responses to questions that will then get entered into my computer and we can show immediate poll results from the class.
表决器是一种小型设备,你可以通过它回答问题,这些答案会传进我的电脑,我们就可以迅速地得到投票结果
What does come out, which is very useful is, if you do run the reaction, here's how much heat comes out.
能得到的结果是,如果我们进行这个化学反应,有多少热量放出,当然这也是很重要的。
And it turns out that the first kinetic energy that we would see or the highest kinetic energy, would be 12 32 electron volts.
结果是我们最先观测到的动能,也就是最大的动能,将是,1232,电子伏,那。
That for an ideal gas it has to be the case that there's no volume dependence of the energy.
我们可以直接推导这个结果,即证明对理想气体,内能和气体体积无关。
That is, you minimize potential energy and you see things falling under the force of gravity and so forthgoing to potential energy minima in conformance with this result.
换句话说,你使得势能最小化,然后发现我们关注的东西,在重力或者其他力的作用下下落,直到势能最小的地方,这和我们刚才的结果是一致的。
So if we look at what we've got here, we've got something rather peculiar, right? What's peculiar about what this computer is now printing for us?
那么如果我们看看,现在我们得到的,结果的话,结果相当奇怪,对不对?计算机现在显示的结果?
And what it turns out is experimental evidence tells us that these two structures are equivalent.
而实验结果也告诉我们,这两种结构是等价的。
Second, we take it very seriously that we need to translate the work we do to humans.
第二,我们是经过慎重考虑的,我们需要将试验的结果应用于人类。
OK, so here is just an engine like what we've already seen, and I'm going to specify that this is a Carnot engine which is to say all the results that we just derived hold for this case.
这一个热机,跟我们以前见过的差不多,我们把它确定为,卡诺热机,所以我们之前得到的结果都对它适用。
And you might every once in a while get this, at least as we've done it in this case, this large move out at the end.
一旦你得到了这个结果,至少像是我们在这个例子中得到的结果,最后有一个很大的唯一变化。
And we must know what the result is supposed to be. Typically when you run an experiment, you say, and I think the answer will be x.
这样我们可以来查看代码的进程,我们还必须清楚结果应该是怎么样的,比如当你运行一个实验的时候。
So we end up having 10 valence electrons.
结果是我们总共有十个价电子。
All right, so that's good.
好吧,我们的结果还是很好。
Let's look at it again. All right it's time to interrupt the world, and we'll just type into the shell.
好,让我们再来看看,好,我们输入shell命令,看结果怎么样。
Which is, and we're going to do some examples of this, initially we just typed in expressions Python into the interpreter; that is,directly into Python And as I suggested last time, the interpreter is actually a program inside of the machine that is basically following the rules we're describing here to deduce the value and print it up.
也就是,我们将会对这一点讲解一些例子,一开始我们只是简单的把表达式输入,到解释器里面去,也就是直接传给,我上次跟大家讲过,解释器实际上是,机器内置的,按照我们描述的规则,来推算出结果值并把值显示出来的一个东西。
Again, wow.
我们显示结果为奇数,然后我们继续。
All right, so it looks like we weren't showing the percentages here, but it looks like hopefully most of you were able to get the correct answer of H2 being the limiting reactant.
看来我们好像没办法,显示结果的比例,但看起来大部分人,都能得到正确的结果,那就是H2是受限制的反应物2,看来现在我们还没搞明白。
it turns out, that this will be a bug, and I want you to think about why it's wrong for me to put this check here.
结果表明我们这儿有一个漏洞,我希望你们去想一想为什么,我把这个check放在这儿就出现漏洞了。
And it sure enough prints what we expected it to print.
现在如果我显示下ivys的内容,它肯定会显示出我们期待的结果。
