So, they thought about this, and they said, you know, this cannot make sense from the standpoint of the plum pudding model.
他们考虑到这一点,他们说,这是不可能的,如果从布丁模型来考虑的话。
And if you're not paying attention to that, the business doesn't succeed, it just falls down.
如果不考虑到这些的话,我们的企业便不会成功。
If you think about what happens when we go from hydrogen to helium, now instead of one electron, we have to describe two electrons, so now we have six position variables that we need to plug into our Schrodinger equation.
如果你们考虑,当我们从氢到氦会发生些什么,现在我们不是要描述一个电子,我们将要描述两个电子,所有我们现在将有6个位置变量,需要加入至薛定谔方程。
If I thought about that fact, it would just be overwhelming.
如果我考虑到这个事实,那真的会是让人无法抗拒的。
You get nineteen times your money over eighty-one years, but then if you take into account the inflation consumes a multiple of eleven and you're an institution like Yale that consumes only after inflation returns, putting your money into treasury bills really didn't get you very much.
1年后你的钱翻了19倍,但是如果考虑通货膨胀,在此期间侵蚀了11倍的收益,而且如果你是像耶鲁这样,减去通货膨胀调整到实际回报后再论支出,那么将钱投资于短期国库券,不会让你赚得多
A kind of consequence of this is if we're thinking about a multi-electron atom, which we'll get to in a minute where electrons can shield each other from the pull of the nucleus, we're going to say that the electrons in the s orbitals are actually the least shielded.
这样的一个后果就是,如果我们考虑一个多电子原子,我们等会就会讨论到它,电子会互相,屏蔽原子核的吸引,我们说s轨道电子,更不容易被屏蔽。
And I picked looking at methane so we could see if there are other factors that we're not considering, that we need to maybe tweak our model a little bit, and I think we'll find that we do if we take a look at a polyatomic molecule, methane, CH4 so c h 4.
我选择甲烷这个例子,我们可以看到,如果有一些我们没有考虑到的因素,我们需要修改一下我们的模型,我们看一看,甲烷CH4这个多原子分子,就会知道这一点,甲烷。
So, for example, we could talk about the n equals 2 state, so that's this state here, and it's also what we could call the first excited state. So we have the ground state, and if we excite an electron into the next closest state, we're at the first excited state, or the n equals 2 state.
例如,我们可以考虑n等于2的状态,它在这里,它也被称作是第一激发态,我们有基态,如果我们把一个电子,激发到它最近邻的态,那就是第一激发态,或者n等于2的态。
