Because we've just sat in lecture and you've told us we're not being rational if we pick a high number.
因为我们刚刚上过课,你告诉我们选大数的人是不理性的
So part of it is, you yourselves have figured out, some of you, that you shouldn't choose a high number.
这对了一半,你们都明白了,不应该选择一个较大的数
Well, we're talking about a pretty high number here, so to make counting easier, we'll just say 10 lone pairs, because 20 lone pair electrons is the same thing as 10 lone pairs.
好吧,我们这里讨论的是一个挺大的数,为了数起来更容易,我们就说有十对孤对电子,因为二十个跟十对是一个意思。
And then the repulsive term, some positive coefficient r and r to a very high number.
然后排斥力,一些正系数,以及具有很大数值的。
It turns out to be a very high number.
结论显示有很大一部分人存在这个问题
If they tend to move together, when x is high and y is high together at the same time, then the covariance will tend to be a positive number.
如果x和y同向变动,当x值和y值同时都很大,协方差的结果将会是一个正值
And this is a very high number because it depends upon electron-electron repulsion.
这个数很大,因为这取决于电子电子之间的排斥力。
And that is why this is such a high number.
为什么会有这么高的数字。
Why is it a high number?
为什么是一个很大的数字?
This is a pretty alarming number because the rates so high already, one can't imagine it going up by another third.
这个速率是如此之高,确实值得引起警惕,人们无法想象这个数字要增加1/3
So, basically any time we have a really high positive number of electron affinity, it means that that atom or ion really wants to gain another electron, and it will be very stable and happy if it does so.
因此,基本上无论什么时候,只要我们有一个很大的正的电子亲和能,这就意味着这个原子,或离子非常希望得到一个电子,如果它得到了,会变得更稳定更开心。
They would bomb it, they would burn it, they would put it in this container inside water, and see how high the water temperature raises and that would give you a sense of the number of calories that it has.
研究人员会燃烧它,放入浸在水里的量热器,然后观察水温上升了多少,我们就对这种食物热量有所了解了
And, it's a very high number.
它是一个很大的数字。
Point number two is that ionic solids at high temperatures make ionic liquids.
第二点是离子固体,在高温下会变成离子液体。
