It's just kind of overwhelming." The modest Holcomb, a stocky man who sports a beard, said he is not the one who deserves all the credit in his black USA-1 sled dubbed "Night Train."

How do we know that everyone choosing 1 is the Nash Equilibrium in the game where you all chose numbers?
我们怎么知道在那个数字游戏中,选择1就是这个博弈的均衡呢
How much quantity would Firm 2 have to produce in order to induce Firm 1 not to produce at all?
公司2的产量达到多少时,公司1会选择停产呢
Harmony is indeed invisible in sense Number 1, you cannot see it with your eyes, but for all that, it can be destroyed.
和声用无形的第一种解读方式理解,确实是无形的,你看不见它,但是它可以毁灭。
All it is sigma 1 s, and then we have two electrons in it, so it's sigma 1 s squared.
所有的都是sigma1s,上面有两个电子,所以是sigma1s的平方。
And, likewise, there will be a test running from 1:05 to 1:55: two different tests of comparable difficulty. I did this last year, and the difference in the scores on all three tests 1% was less than 1%.
还有,测试的时间会是,从1点5分到1点55分,两个不同的测试,但是难度差不多,我去年这样做过,3个测试的分数的区别,不到。
They all died. And it was--not everybody, but in France 1,500,000 people died, and that's a huge demographic chunk, it's like a big shark took a big bite out of your basic pyramid of your demographic tree.
都死了,的确是,倒不是所有人,但是在法国有一百五十万人阵亡,这在人口比例中占很大一部分,就好像一个大鲨鱼照着,人口树的基底咬了一大口
b Star B in the last line of code now means find B, 1 2 3 all right, that's 1, 2, 3.
在最后一行的*b意思是查找,好的,那是。
That's just the those-- let me use my pointer that's just these two lines here. I checked the value, and in one case, I'm changing the last to be mid minus 1, which is the case I'm in here and I just call again. All right?
来看看ppt,这里有两条线,我检查了值,在一种情况下,我把last指向了中点减一,就是这种情况,我们再来调用一下怎么样?
And none of this has an S1 in it, so that all goes away.
1在这里面就都消掉了
If we look at our last structure here where we have nitrogen the middle, we can also figure out all those formal charges, and in this case we have plus 1 on the nitrogen, we have minus 2 on the carbon, and then we end up with a 0 on the sulfur there.
如果我们来看看最后一个结构,在中间的原子是氮,我们同样可以计算出所有的形式电荷,而在这种情况下,氮为正一,碳为负二,而最后硫为零。
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。
Remember, because that 1 s orbital is all the way down in terms of if we're thinking about an energy diagram, we're all the way down here, so we have a huge amount of energy we have to put into the system in order to eject an electron.
还记得吧,因为1,s,轨道在能量示意图里,是在最底部的,我们要一直到最下面,所以我们要向这个系统注入非常大的能量,才能打出一个电子。
