Actually, what I did was used 107kJ/mol a different source so I have 107.
事实上,我使用了另一个路径,计算得到了。
So really what we'll probably do is instead either give you the wavelength or the frequency and you'll go ahead and calculate the energy from there.
所以实际上我们可能的做法是,给你波长或者频率,然后你可以通过他们计算得到能量。
It was as if, when we went through this search tree, we never remembered what we got at the bottom, and we just re-computed things over and over.
如果当我们遍历完这棵树,我们不可能,记得我们在最下面得到什么结果,我们只是不断地重复计算,所以这让。
So we have this condition that's established in a quantity that we know how to calculate.
在种种条件下,我们得到了一个我们知道如何计算的物理量。
This one is calculable by the Bohr model because lithium 2plus is a one electron system.
这个可以通过波尔模型计算而得到,因为锂2+是单电子系统。
With an indexed bond you don't have to do this calculation to get the real rate.
对于物价指数债券,你无需,通过以上计算得到实际利率
What it means is if you'd release a rock at that location one second before with a certain speed that we can calculate, it would've ended up here with precisely the position and velocity it had at the beginning of our experiment.
它的意义在于,若在该处以特定速度抛出一个物体,这个速度可通过计算得到,一秒之后,物体会运动至我们设定的起点,并且速度为我们设定的初速度
The first thing to do is to go over here where it says, My Plate Calorie Counter, you'll actually get more information than just calories, but if you go over here, click on this, then the next version you'll see will be something like this.
首先你要看一下这里,写着,我每餐的卡路里计算器,你可能得到的不只是卡路里的信息,如果点击这里,接下来你会看到这个画面
But that's not enough because computers at the end 1 of the day only understand 0s and 1s and what you and is clearly not a collection of 0s and 1s.
但是仅仅这样是不够的,计算机,最终只会认识0和,你现在得到的,c的文件显然不是0,1的合集。
Our goal is to take problems and break them down into these computational steps, these sequence of instructions that'll allow us to capture that process.
我们的目标是得到问题,然后将问题分解为这些计算步骤,这些指令集,可以让我们看到这个过程。
So, what he did was kind of impose a quantum mechanical model, not a full one, just the idea that those energy levels were quantized on to the classical picture of an atom that has a discreet orbit.
还不是完整的,只是这些能级,是量子化的概念,作用到原子有分立轨道的经典原子模型上,当他做了一些计算后,他得到有个半径,他算出来。
That is the final aspect of the efficient portfolio calculations.
那是计算有效资产组合所得到的最终结果。
They would pull out your entire life history of contributions-- they had it because you had filed it all at the post office and everything was bureaucratic and efficient-- and they calculated, according to a formula, what you would get.
政府会取出你这一生的交保记录-,这是由你自己在邮局填写的,所有的一切都行之有效-,然后他们根据公式计算你能得到养老金。
And, that gives you a number for the fluorine, minus 0.29. Now, if you do the same for the hydrogen, you'll come up with the same number.
然后给出F的数字,负的0。29,如果同样的用H来计算,你会得到一样的答案。
If you go and work that out, log2 log of two and you have two log two, by math you can show that for the line r series m 2*log2 is equal to two natural log of two, which is 1 1.386 which is greater than one.
如果你把它计算出来,这二者的对数,你会得到2个,通过数学,你会得到第r列,第m个值,等于,也就是1。386,这大于。
And it turns out that if we have a, for example, for s, a very large z effective or larger z effective than for 2 p, and we plug in a large value here in the numerator, that means we're going to end up with a very large negative number.
结果是如果我们有一个,举例来说对于s一个很大的有效电荷量或者,比2p大的有效电荷量,并且我们将一个较大的值代入计算器,那意味着我们最后会得到,一个非常大的负数。
