摘　　要：当空间发生旋转时,自旋算符沿某方向的投影和其本征态都会发生变换,但是变换后的自旋态应该还是变换后的相应算符的本征态.本文利用这一原理讨论了空间旋转引起的自旋态的变换,得到了与轨道波函数类似的变换公式.最后还讨论了空间旋转引起的一般角动量的变换公式.When space undergoes rotation,both the projection of the spin operator along a certain direction and its eigenstate undergo transformation,but the transformed spin state should still be the eigenstate of the corresponding operator after transformation.This article uses this principle to discuss the transformation of spin state caused by spatial rotation,and obtains a transformation formula similar to the orbital wave function.Finally,the transformation formula of general angular momentum caused by spatial rotation is discussed.

关 键 词：自旋 自旋算符 自旋态 空间旋转
