Now I have lambdas associated with transitions between energy levels in atomic hydrogen.
现在我把波长和,氢原子中的,能级跃迁联系起来。
It's been shown that higher levels of education correlate with high voter turnout.
有研究显示,教育程度越高,选民的参与度越高。
What we're going to start with is discussing photoelectron spectroscopy, which is a spectroscopy technique that will give us some information about energy levels in multielectron atoms.
首先,我们将讨论,光电子能谱,通过这种技术,我们能够得到多电子原子的能级信息。
Many people said the problem with general levels of happiness or unhappiness rather, the cause is people have too high expectations.
很多人说,一般的快乐或不快乐水平,是由于人们有过高的期望。
And that is that the energy levels themselves change with electron occupancy.
就是能级本身,也会随着电子的排布发生变化。
Linguists can work at different levels of abstraction with language.
根据不同层面的基本单位,语言学家有不同的研究。
People do that with differing levels of efficiency.
人们存储能量的效率各不相同
And very interesting for positive psychologists, those concerned with wellbeing and happiness: their wellbeing and happiness levels were incredibly similar.
让积极心理学学者,和研究幸福和快乐的人,更感兴趣的是:,这些双胞胎的幸福和快乐水平非常相似。
So what we'll start with today is talking about the technique that's primarily used to actually experimentally figure out what these different energy levels are.
因此,我们今天首先要讨论的就是,最常用来在实验上,确定不同能级的技术。
So that's just a little bit of a check for yourself, and it should make sense because what you're doing is you're calculating the difference between energy levels, so you just need to flip around which you put first to end up with a positive number here, and that's a little bit of a check that you can do what yourself.
所以你们总要确保括号,离得这项是正的,这是你们自己,可以做的检查,这事很有道理的,因为你们做的是计算能量差,所以你需要调整顺序来保证一个正数,这是你们自己可以做的检查。
So, if we start instead with talking about the energy levels, we can relate these to frequency, because we already said that frequency is related to, or it's equal to the initial energy level here minus the final energy level there over Planck's constant to get us to frequency.
如果我们从讨论能级开始,我们可以联系到频率上,因为我们说过频率和能量相关,或者说等于初始能量,减去末态能量除以普朗克常数。
What has been found over the last 10 years and a little bit longer is the most effective way of actually dealing with a rising levels of depression in our culture, with individual depression or anxiety is actually not to that is important as well.
过去10年多时间的研究发现,处理我们不断增加的抑郁病例,个体的抑郁或焦虑,最有效方法是,这点也很重要。
