时角，是天文学中的一个重要概念，常用符号t表示。一个天体的时角定义为天子午圈与天体的赤经圈在北极所成的球面角，或在天赤道上所夹的弧度。 时角随地球的自转而变化，且与测者所在的子午圈有关。时角的单位通常采用相应的时间单位，以0~24时取代0°~360°。

You can also have angular notes, and when we talk about an anglar node, what we're talking about is values of theta or values of phi at which the wave function, and therefore, the wave function squared, or the probability density are going to be equal to zero.
我们也可以有角向节点，当我们说道一个角向节点时，我们指的是在某个theta的值,或者phi的值的地方，波函数以及波函数的平方，或者概率密度等于零。

In contrast when we're looking at a p orbital, so any time l is equal to 1, and you look at angular part of the wave function here, what you see is the wave function either depends on theta or is dependent on both theta and phi.
