分布密度亦称“概率的分布密度”。设某连续随机变量落在某区间内的概率为P,△x>0是区间的长度,则P/△x的比值叫做随机变量在该区间上的“平均概率分布密度”,如果当区间长度△x→0时,比值的极限存在,则这极限叫做随机变量在点x处的概率分布密度,简称分布密度。

We'll start with talking about the shape, just like we did with the s orbitals, and then move on to those radial probability distributions and compare the radial probability at different radius for p orbital versus an s orbital.
