Even in the case of this spring, when you pull it, if you pull it to the right by some force.
甚至是在这样的弹簧问题中,当你拉它的时候,如果你用力向右拉
In the opposite case, if you have a compression, then it's the opposite of expansion.
绝热压缩,的情况,与此相反。
Then you make money if the price of the stock rises above, in that case, $11 a share.
如果股票的价格高于十一美元,你就能够盈利
So we see that we do not eject electrons in the case of the laser pointer, even if we have this intensity, it is still not related to the energy of an individual photon, so we won't see an effect.
所以我们看到我们用激光笔,还是没有逐出电子,即使我们有这样的强度,它仍然与一个单个的光子能量无关,所以我们不会看到光电效应。
If a case of polio emerged in the community, the chances that it could spread to other children or to your child were high; so, great interest in this in the early part of this century.
如果在某个社区出现一例脊髓灰质炎患儿,那么你的孩子或者更多别的孩子,被传染的几率非常高,所以 二十世纪初的科学家们,热衷于研究脊髓灰质炎
If the body view adds the no branching principle, then we can say,look,in the case of this sort of splitting-- This example is known in the to philosophical literature as fission, like nuclear fission when a big atom splits into two.
如果肉体理论加入无分支原则,我们就能说,在这种分裂的情况下-,这种分裂在哲学文献中叫做裂变,就像原子一分为二的核裂变。
Basically if you have a number that's P in this case, than the number is lower then that shows increasing level of statistical significance.
基本上如果P,这幅图里的数比0.05更小,数字越小,表示统计学显著性越大
I've got to test to see if I'm in the base case, and if I'm not, then I need to move a tower of size n minus 1, I need to move a tower of size 1, and I need to move a second-sorry about that a second tower of size n minus 1.
首先我看看我是不是在最基本的情况,如果不是的话,我得先做一个N-1个,圆盘的移动,移动一个圆盘,然后再做一次N-1个圆盘的移动。
How many moles of gas are there in each case, in reactants and products? If that changes, of course you know that the pressure in there is going to change at constant volume if the amount of gas in there is changing.
在反应物和生成物中,各有多少摩尔的气体?,如果它发生了变化,当然在等体条件下,如果气体的总量,发生了变化,压强也会发生变化。
And if we talk about chlorine, and both of the chlorines are the same in this case, we start with a valence number of 7 for chlorine, and then we subtract 6, because it had 6 lone pair electrons around each of the chlorine atoms.
而如果我们讨论氯的话,在这个例子中两个氯的情况都是一样的,从七个价电子开始,然后减去六,因为每个氯原子周围,都有六个孤对电子。
So for example, if you look at the 1 s orbital here, you can see that actually it is lower in the case of the multi-electron atom than it is for the hydrogen atom.
所以举例来说,如果你看到这里的1s轨道,你可以看到实际上,多电子原子情况的。
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。
