So, that's the second quantum number.
这就是第二个量子数。
And I promise, this is the last quantum number that we'll be introducing.
我向你们保证，这是我们最后遇到的一个量子数。
And our equation for total nodes is just the principle quantum number minus 1.
总节点数等于，主量子数减1。
And each one of these energies, if it's a molecular energies, can be indexed by a quantum number of some sort.
每一项能量，可以用某个量子数标记。
So we can have, if we have the final quantum number m equal plus 1 or minus 1, we're dealing with a p x or a p y orbital.
所以如果我们有,磁量子数m等于正负1,我们讨论的就是px或者py轨道。
When the rotational quantum number J is greater or smaller than 16, the absorptivity almost exponentially decreases with the increase or decrease of the J.
当转动量子数J大于或小于16时，吸收值随J值的增大或减小几乎成指数减小。
But at the time, they didn't have a well-formed name for it, they were just saying OK, there's this fourth quantum number, there's this intrinsic property in the electron.
但在那时，人们没有给它取名，他们只是说ok，这是第四个量子数，这是电子的本征性质。
The cranking term breaks the time reversal symmetry, and the projection of the single particle angular momentum on the intrinsic symmetric axis is no longer a good quantum number.
推转项的引入破坏了时间反演对称性，单粒子角动量在内禀对称轴上的投影量子数已不再是好量子数。
In our case, the two modes differ in the internal quantum number, and are a clearly distinguishable subsystem. We can thus regard the two coupled BECs as a bipartite system of the modes.
由于单个玻色原子不是可区分的子系统，我们把系统看成一个两模系统，用冯诺依曼熵来度系统的量子纠缠。
It is pointed out that the relation has something to do with the principal quantum number and the angular quantum number, but nothing to do with the nuclear electronic number and reduced mass.
发现此关系式与主量子数和角量子数有关，而与核电荷数以及折合质量无关。
So if we're talking about the fourth excited state, and we talk instead about principle quantum numbers, what principle quantum number corresponds to the fourth excited state of a hydrogen atom.
如果我们说的是，第四激发态，我们用，主量子数来描述，哪个主量子数对应了，氢原子的第四激发态？
