氣質是可以修煉的,你也可以,從現在開始,你也可以優雅如鹿。
Some of the excited atoms undergo radiative deexcitation.
然後閉上眼睛,再睜開眼睛,告訴自己,我終於重生了。
Being very high intensity, this focus induces a population inversion in the oxygen atoms, ensuring that there are more excited than non-excited atoms.
The boundary radii of excited atoms are defined by the classical turning point of the electron moving in an atom.
