So, one difference between photoelectron spectroscopy and, for example, the photoelectric effect is that in this case, we're not just looking at one energy level, which is what we were looking at from the surface of a metal, now we're talking about this gaseous atom.
光电子能谱与光电效应的不同点在于,以这种情况为例,我们不只关心一个能级,就像原来在金属表面那样,现在我们研究的是气体原子,所以,我们可以从原子中。
"We know that surface use of dispersants decreases the environmental risk to shorelines and organisms at the surface and we know that dispersants break down over weeks rather than remaining for several years as untreated oil might."
