经典物理中的轨道角动量和自旋角动量

Orbital Angular Momentum and Spin in the Classical Physis

从经典力学中质点系的角动量导出轨道角动量和自旋角动量的概念,并给出如地球运动的自定轴运动刚体的轨道角动量和自旋角动量,以及一般运动刚体的轨道角动量和自旋角动量.

Derived the concepts of orbital momentum and spin from the angular momentum of the particles system in Classical Physics, and gotten the orbital momentum and spin of the self - fix - axis movement of a rigid body resemble with the movement of the Earth, and further derived out the orbital angular momentum and spin of the general movement of a rigid body.
