It is the value of the radius of the ground state electron orbit in atomic hydrogen.

它就代表氢原子基态电子,的轨道半径。

Let's look first of all at the radius of the orbit.

首先是轨道半径。

n So the velocity is given by this product of the quantum number n Planck constant 2 pi mass of the electron time the radius of the orbit, which itself is a function of n.

速度是量子数,普朗克常数2π乘以轨道半径的值,它自身也是n的函数。
