When the frequency of laser standing wave is higher than the resonant frequency of atoms, the atoms will be focused on the wave node of the standing wave.

当激光驻波场的频率大于原子的共振频率时，原子由于受到偶极力的作用将被会聚到驻波的波节处。

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。
