One is a little bit higher and one is a little bit lower than they are in the atomic situation.
一个有点高,一个有点低,相比他们是原子状态的情景而言。
And then there's means tested where if you have a lower household income,
然后,还会有一个测评,如果你有很低的家庭收入,
So do you think noble gases would have a high positive electron affinity, a low positive, or negative electron affinity?
那么,你认为稀有气体的电子亲和能,应该是一个高的正值,一个低的正值,还是一个负值?
In fact, if that person has a 48 and the first person who had the weaker score has a 46, I could still pass the person with the 46, and fail the person with the 48.
事实上,如果这个人得了48分,而第一个人,得分低一点,是46分,我还是会让46分的人通过,而让48分的人挂科。
One of the hypotheses that was being tested in this particular study was that a low-fat diet would reduce a woman's risk for breast cancer.
其中一个,在研究中被检验的假设是,低脂膳食,有助于降低妇女患乳腺癌的风险
There are lots of costs, so you want to have a loan-to-value ratio, which is sufficiently low, that the collateral will cover the value of the loan.
那是一大笔开销,因此你要设定一个足够低的,贷款价值比率,使得抵押物价值能够为贷款提供保障
He returns us to the lowly perspective that Galileo had when he set up his telescope in that other valley, Valdarno, and it's this lowly vantage point that's beautiful in part because it's a fallen perspective, not in spite of the fact that it's a fallen perspective.
他让我们回到伽利略和他在另一个村庄,瓦尔达诺设置望远镜的较低的层面,这个低下的认为这个层面存在美感的观点,是因为这是一个堕落的观点,而不是因为堕落的事实。
You--By not randomly assigning people to these two conditions, you may be capturing just individual differences in the kind of person who, when there's a perfectly stable, safe, low bridge, says, "Huh uh. I won't want to go on that bridge.
如果两种情况下的受试者不是随机安排的,或许你所捕捉的,只是一类人中的个体差异,这类人,当看到一个更稳定,更安全,更低的桥,会说,“啊哈,我不走那座桥。
We're singing below middle C and the ladies are singing up an octave but that's still monophonic texture-- those notes have the same names.
我们唱得比中央c低,而女士们高了一个八度,但这还是单音织体,这些音的音名是一样的
The payoffs are lower, Okay. So here's an abbreviated version of that, I mean it's perhaps a little bit longer.
回报较低,我有一个比较简约的说法,我是说可能有点长
So, in contrast, if it has a low electronegativity, this then is going to be an electron donor.
那么,相反地,如果它的电负性很低,它将会是一个电子的施主。
So specifically, what we're asking here is as we go across the periodic table, we want to consider which has the smaller ionization energy.
具体地说,我们这里要问的是,从周期表来看,你认为,哪一个元素的电离能更低。
We start at this lower energy state and go up that means we need to absorb a photon, we have to take in energy.
我们从一个低能级开始,到一个高能级去,这意味着需要吸收一个光子,我们要获得能量。
That makes sense because we're losing energy, we're going to a level lower level, so we can give off that extra in the form of light. And we can actually write the equation for what we would expect the energy for the light to be.
这很合理,因为我们在损失能量,我们要到一个更低的能级去,我们要以光的形式给出额外的能量,我们可以写下光能量的方程。
A much smaller peak, a much less rapid decline after the peak occurs.
一个较低的峰值,最大值出现后下降速度也较慢
They put it in a pretty low impact paper.
他们把它发表在一个影响力很低的杂志上。
% Some people, the next most popular answer with 5%, which is a nice low number, wanted to put two in the 2 p x before they moved on.
下一个更多的选择占了,是一个比较低的数字,想要将两个电子在移动之前放入2px轨道,记住在我们双倍填充之前。
Another way to say that it's going to be less, so you don't get confused with that the fact this is in the numerator here, there is that negative sign so it's less energy but it's a bigger negative number that gives us that less energy there.
另一个方式去说它将会变得很低实用,你们不用在这里的计算器的事实感到迷惑,这里有一个负号实用,它是更少的能量,但它是一个更大的数字,这里了它给了我们更少的能量。
Absorption is just the opposite of emission, so instead of starting at a high energy level and dropping down, when we absorb light we start low and we absorb energy to bring ourselves up to an n final that's higher.
吸收就是发射的逆过程,与从一个高能量到低能量不同,当吸收光时,我们从低能量开始,吸收能量到一个更高的能量。
This intuitively should make a lot of sense, because we know we're trying to minimize electron repulsions to keep things in as low an energy state as possible, so it makes sense that we would put one electron in each orbital first before we double up in any orbital.
这个直观上讲得通,因为我们知道尝试去最小化电子排斥力,从而尽可能的保持处于一个较低的能态,所以它讲得通,在我们在同一个轨道放入两个电子之前,我们首先把电子放入每一个轨道。
If a company--if its stock sells for less than its assets are worth then the company maybe should be broken up and the assets taken and given somewhere else because the low stock price indicates a problem.
如果一家公司---如果它的股票卖的,比它的资产价值低,那么这家公司也许就应该破产,并且,它的资产就应该被占用或分配到其他地方,因为低的股票价格预示着一个危机。
So here we have energy increasing on the y-axis, and you see this straight line at the bottom here is lower down on the graph, and that's the energy of a bound electron, so that's going to be a low stable energy.
这里我们看到能量沿着y轴增加,而且在这张图片上,这条直线在底部是降低的,那是一个束缚电子的能量,所以那是一个低稳态能量。
The z effective is lower, so we have to put less energy in to get an ion out.
它的有效核电量更低,所以我们只需要更少的能量就能打出一个离子。
Buying them tends to push up the price; that tends to influence the yield down so it encourages a lower level of interest rate.
买进它们,导致价格上升;,导致参数降低,所以它鼓励一个低的利率水平。
So this means nitrogen has low electron affinity, it doesn't actually want to gain an electron.
这意味着氮的电子亲和能很低,它实际上并不愿意得到一个电子。
So, if you use a black lamp or something and you excite something up to a higher energy level and then it relaxes back down to its lower energy state, it's going to emit a new wavelength of light, which is going to be visible to you.
如果你用一个紫外灯或别的,东西把某种分子激发到,更高的能级,然后它会掉回,到低能级,它就会释放,一个新的波长的光,这个光是可见的。
I believe that we have quite a low risk portfolio.
我相信耶鲁因此才有一个低风险的组合
So in other words a very low energy is what we're going to have when we talk about the orbitals -- the energy of the 2 s orbital is going to be less than the energy of the 2 p orbital.
换句话说一个非常低的能量,是我们将会得到的当我们谈论轨道时,2s轨道的,能量比2p轨道,的能量低。
So if we don't have to hybridize one of the p orbitals, we can actually end up with a lower energy situation, because now these s p 2 orbitals are 1/3 s character, and only 2/3 p character, instead of 3/4.
我们的杂化轨道就有更多的p轨道成分,所以它们的能量更高,如果我们不杂化这个p轨道,我们可以得到一个能量更低的情况。
That's not a way that we really think about it, but I do believe that the risk level of the University's portfolio is really quite low in statistical terms -much lower than the risk level that you'd have if you had a traditional portfolio dominated by marketable securities.
这一般不是我们考虑的关键,但我相信,耶鲁投资组合的风险水平,在统计数字上是非常低的,远远低于,持有一个传统的可交易证券主导的,投资组合的beta系数
