density function

基本解释

This cartoon shows the probability density function of 1s.
下面这个动画表示了,数1s轨道的概率密度函数。
Well, it depends on what you know about the measurements' probability density function (PDF).
它依赖于您对度量值的概率密度函数（probability density function，PDF）的认识。
Figure 1 shows a typical normal probability density function, so called because most observations fall into this sort of distribution.
图1显示了一个典型的正态概率分布函数，这样命名是因为绝大多数值都属于这个分布范围内。

This cartoon shows the probability density function of 1s.
