How do we go from that experiment to H the terms that we're trying to get, these slopes.
我们怎样从实验得到我们想要的量?,记住,我们想要得到Δ
I also think that if you were to go a little bit lower than that in terms of like...
我还想,如果你想要比它稍微档次低点儿的,比如……
And from there, I go to... saying well, what can we do in terms of global poverty?
由此,我想到,我们可以为全球的贫困问题做些什么呢?
What made things go so awry that people and food used to be more in sync in terms of health and well-being, although there were problems in some ways.
是什么让一切偏离正轨,尽管有些方面存在种种问题,过去人与食物的关系,就健康方面而言,要比现在更为和谐
One is in terms of how you deliver the molecule so it goes where you want it to go and not where else you want it to go.
其一是如何精确输送这种分子,到你想要的部位
If we go to the oxygen atom, now we're talking about starting with 6 in terms of valence electrons again, but instead of 2, you can see we have 6 lone pair electrons around the oxygen minus 1/2 of 2, so we have minus 1 is our formal charge.
如果我们分析氧原子的话,现在我们讨论的还是,从六个价电子开始,但孤对电子不再是两个了,你会看到氧周围,有六个孤对电子,再减去二的一半,因此我们有一个负的形式电荷。
in terms of quality. I know, for instance, that I wanted to go to see an exhibit last April,
就质量而言。例如,去年四月我想去看展览,
We decrement so to speak the variable and then where will we go next in terms of the flow control, the flow of this program.
可以这么说,我们递减这个变量,然后按照控制流,即程序流进入到下一语句。
There are two principles that I want to go through very quickly in terms of Socrates.
苏格拉底有两条原则是我想,快速介绍一下的。
Now, we're going to go back to Roger Ibbotson at the School of Management. He did some path breaking work in terms of describing capital markets returns over reasonably long periods of time.
先讲回到管理学院的罗格·伊博森,所进行的开创性研究,描述了在相当长的时期内,资本市场的收益情况
So the point of this is: once you get these kind of progressions locked in your ears, you go to a concert and you can begin to chart what the piece is doing in terms of its harmony.
这里的重点是,一旦你的耳朵牢牢记住了这些进程,你去听音乐会的时候就能开始分析一部作品的和声了。
It's always a good first approximation, because you need to start somewhere in terms of drawing Lewis structures, but then if you go and figure out the formal charge and you just have lots of charge separation or very high charges, like a plus 2 and a minus 2 and a minus 1 all different places in the atom, what it should tell you is maybe there's a better structure.
它总是一个好的第一近似,因为在画路易斯结构的时候,你总需要一个起点,但是如果你在算出形式电荷之后,发现有很多电荷分开了,或者说有很高的电荷,比如有一个正二,一个负二,还有一个负一1,在原子的各个地方,这应该就是在告诉你,或许还有一个更好的路易斯结构。
All right, so we can go to today's notes, and in terms of the notes, what we're going to start with is finishing material that's going to be relevant for exam 1, and I told you on Wednesday that actually I'd give you some information today in terms of what you need to do to prepare for exam 1.
好,下面我们进入今天的讲义内容,而依照讲义,我们今天首先,要把第一次考试要求的最后一部分内容讲完,而且我周三曾经告诉过大家,我会在今天把一些信息告诉大家,是关于如何准备第一次考试的。
And also I wanted to mention in terms of checking your Lewis structures, regardless of what they are, you should always go back and I had 10, and then count 2, 4, 6, 8, 10, because you always need to make sure you have the same number of valence electrons that you calculated in your actual structure.
我还想提一点关于检查,你的路易斯结构的建议,不管它们是什么,你总是应该回去检查一下,我有十个,然后数一数,二,四,六,八,十个,因为你总是需要确保实际价电子的数量,与你在结构中算出的数量相等。
Often a good thing to start with is to put the lowest ionization energy atom in the middle, and if you don't have charge separation then go with that structure, but if you do find you have a lot of separation, such as the case in negative 2, positive 2, and minus 1, then you want to say wait a second, this is really bad in terms of formal charge, let me go ahead and see what other options I have here.
通常一开始把电离能最低的原子,放在中心位置就很好了,如果你发现电荷没有分开,那么这个结构就没问题了,但是如果你发现有很多分开的电荷,比如这种情况,有负二,正二和负一,那么你会想要说等一下,从形式电荷来看这很不好,让我去看看其它可能的选择。
It's a little bit of a digression, but one of the things that I've witnessed over the past twenty years is that the leakage of the -the leakage from the system in terms of the returns that go to the owners of capital -leakage has increased enormously.
讲一点稍稍离题的内容,我发现,过去的二十年中,这种损耗,这种减损资本所有者收益所得的,系统性损耗,有相当巨大的增长
