The radiation is due to the motion of change and has nothing to do with the spin of the electron . 因为辐射是由于电荷的运动所产生的，而与电子的自旋无关。
Further, in this case the wave functions can be factored into a space and a spin portion . 此外，在这种情况下，波函数可以分解成一个空间部分和一个自旋部分。
The main point we shall be interested in is the influence of the total electron spin on the energy of the system . 我们将感兴趣的主要之点，就是电子总自旋对系统能量的影响。
Doublet fine structure results from spin-orbit coupling and the two possible relative orientations of s and l . 双重精细结构起源于自旋一轨道耦合以及S和L的两个可能相对取向。
A spin polarizer is a device that allows atoms of only one definite spin orientation to pass through it . 自旋偏振器是这样一种装置，它只允许具有某一确定自旋取向的原子通过。
As the electron carries nature's smallest unit of electric charge, it also carries the indivisible unit of spin . 因为电子是携带电荷的天然最小单位，所以电子也携带不可分的自旋角动量单位。
The transition from ferromagnetism to paramagnetism involves a transition from ordered to disordered orientations of electron spins . 由铁磁性转变为顺磁性涉及到电子自旋的取向由有序向无序转变。
Spin-orbit coupling is the interaction between the spin magnetic moment of an electron and magnetic field generated by its orbital motion . 自旋-轨道耦合是电子的自旋磁矩和由轨道运动产生的磁场之间的相互作用。
If the spins are in the same direction, the state is called orthopositronium; if they are opposite, we speak of parapositronium . 若方向相同，则称该自旋态的电子偶素为正电子偶素；若方向相反，则称为仲电子偶素。
A strong magnetic field in a resonant cavity is an ideal circumstance for initiating the spins and orbital motions of electrons and nuclei in solids . 谐振腔中的强磁场是激发起固体中电子和原子核的自旋和轨道运动的理想环境。
