So by using the tabulated data, we can really determined heats of formation for most reactions that you might contemplate, OK?
所以,使用这些表格,我们就能确定大多数,你可能碰到的反应的生成热?
But what you should be able to do is take a look at a list of answers for what we're saying z effective might be, and determining which ones are possible versus which ones are not possible.
但是你们应该能够做到的,是看一下这个可能的,有效电荷量的答案列表,并且确定哪些是可能的,哪些是不可能的。
You had to choose grades, so you had to choose Alpha and Beta, and this table told us what outcome would arise.
大家通过选择α和β来确定各自的成绩,这个表格列出了可能的结果
if we do introduce a third possibility-- I'm not sure this is the right thing.
如果确实加入这一种可能-,我不确定这是对的。
It is a much scarrier idea than saying I have this, I'm going to do it, I'm going to put it down there as opposed to being open to what may come and being uncertain whether that would be something good enough.
这和,我知道了,我要做这个,我想写这个,这种确定感相比,对可能的结果保持一种开放的心态,不知道,期待能否满足的未知感相比,更挑战一些。
a lot of focus is on what is the range of moderately probable outcomes.
将很多精力用于确定,可能性产出的合理范围。
And what the second point of Aufbau says is that as electrons begin to fill those levels the differences in energy may shift so that in an unoccupied state certain levels may be in the inverse order from how they are in the occupied state.
构造原理谈到的第二点是,当电子开始布满这些层时,能量差可能会有改变,所以在一个未占据的确定能级,可能与它们占据时,的排布顺序是相反的。
This particular website has this free nutrient analysis On the website people may choose to get involved in and there may be charges for those things, I don't really know, but there may be and then they may ask you for identifying information, but it's your option to do that.
网站的营养分析服务,在该网站,人们可以选择使用其他服务,当然,那些可能是收费的,我不是很确定,可能有收费服务,并要求验证个人信息,但这由你自己选择
In this case, I probably want to make sure I use absolute value of x before I carry it on. Yes ma'am.
在这个例子中,我可能想确定,在进行测试前我用的是x的绝对值,什么问题?
NO So that the more complete answer to the question is that no, we're never going to be able to observe that because of the uncertainty principle it's not possible to observe a velocity that's this slow for a macroscopic object.
所以这个问题的完整答案是,由于不确定性原理,我们不可能测量到这么慢的,宏观物体的速度,希望这个解释。
I might not be sure whether the opponent, whether my opponent, is choosing Left or Right.
我可能不太确定,我的对手会选择左还是右
So you can see that we're starting to have a very complicated equation, and it turns out that it's mathematically impossible to even solve the exact Schrodinger equation as we move up to higher numbers of electrons.
所有你们可以看到我们得到了,一个非常复杂的方程,结果是它在数学上是,不可能解出确定的,薛定谔方程,当我们考虑更高的电子数目的时候。
