因此，它就是度量一个给定原子有多么，想把电子密度拉过来，可以说，从相邻的一个原子那里。

So it's just a measure of how much does one given atom want to pull away electron density from, let's say, an adjacent atom.

它依赖于您对度量值的概率密度函数(probability density function, PDF)的认识。

Well, it depends on what you know about the measurements' probability density function (PDF).

并且它还是仪器校准的标准程序之一，甚至作为度量单位使用，“millicrab”译注：即千分之一的蟹状星云辐射密度。

It's routinely used for instrument calibration and even as a unit of measure, the "millicrab."
