excited atom

基本解釋

Both interactions of a two-level atom with a vacuum field and a excited atom with a coherent field, as examples, are discussed in detail.
作爲(wèi)例子，詳細(xì)討論了二能級(jí)原子與真空?qǐng)龅南嗷プ饔靡约皠I於激發(fā)態(tài)的原子與相乾場(chǎng)的相互作用。
Quantum electrodynamics formulas are applied to calculate the spontaneous emission rate of an excited atom in the vicinity of a perfect reflecting mirror.
利用腔量子電動(dòng)力學(xué)計(jì)算了原子在全反射鏡麪附近的自發(fā)輻射率。
The spontaneous emission phenomenon of an excited atom is one of basic processes in quantum optics.
激發(fā)態(tài)原子的自發(fā)輻射現(xiàn)象是量子光學(xué)領(lǐng)域是最基本的過程之一。

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.
如果我們說的是,第四激發(fā)態(tài)，我們用,主量子數(shù)來描述，哪個(gè)主量子數(shù)對(duì)應(yīng)了,氫原子的第四激發(fā)態(tài)？

So, what we know is happening is that were having transitions from some excited states to a more relaxed lower, more stable state in the hydrogen atom.
我們知道，這裡所發(fā)生的是,氫原子從激發(fā)態(tài)到更低更穩(wěn)定的態(tài)的躍遷，而我們用眼睛可以探測(cè)到的。

So another way to say that is, in a sense, if we're thinking about the excited state of a hydrogen atom, the first excited state, or the n equals 2 state, what we're saying is that it's actually bigger than the ground state, or the 1 s state of a hydrogen atom.
換句話說，如果我們激發(fā)一個(gè)氫原子，第一激發(fā)態(tài)或者說ｎ等於２的態(tài)，我們說它比氫原子基態(tài),或者說１ｓ態(tài)要大。

Once that is done, another laser pulse will jostle the virus from its ground state into an excited state, just as a single atom is excited by moving one of its electrons from a lower to a higher orbital.
