〔spin〕The intrinsic angular momentum of a subatomic particle. Also called spin angular momentum 转动惯量：亚原子粒子的自旋角动量 也作 spin angular momentum〔spin〕The total angular momentum of an atomic nucleus.原子核的角动量之总和〔gyrocompass〕A compass with a motorized gyroscope whose angular momentum interacts with the force produced by the earth's rotation to maintain a north-south orientation of the gyroscopic spin axis, thereby providing a stable directional reference.陀螺罗经：一种装有机动陀螺仪的罗盘，由于陀螺仪的角动量与地球的自转产生的力相互作用，使陀螺转轴一直保持南北方向，从而提供一个稳定的方向指示〔spin〕A quantum number expressing spin angular momentum.量子数：表示自旋角动量的量子数 |
