angular rotation

Is the state of the axial rotation of a rigid body at constant angular speed stable?

刚体的匀角速定轴转动状态是平衡态 吗 ?

Secondly, the principle of optical rotation due to the transfer of spin angular momentum and orbital angular momentum from light to birefringent particles is discussed by analyzing the interaction between the beam of light and birefringent crystal particles.

其次，从理论上分析了偏振光束与双折射晶体粒子的相互作用机制，并分别讨论了由于光束自旋角动量和轨道角动量向双折射晶体粒子的传递所导致的光致旋转效应的原理。

Rotation effect has the great influence on star in the former stage of main sequence and in the latter stage of Red Giant through the angular velocity and the change of rotational angular velocity; turbulent pressure in the stage of AGB star. ( 3).

自转效应通过自转角速度和自转角速度的变化对恒星在主序星前期和红巨星后期的影响较大，而湍流压在AGB星阶段的影响较大。

More precisely curl v measures twice the angular velocity, or maybe I should say the angular velocity vector because it also includes the axis of rotation.

更精确地，curv，v值为角速度的2倍，或许我应该说，角速度向量，因为它带有旋转轴。

Concretely, this curl gives you the angular velocity of the rotation, well, with a factor two but that doesn't matter, and the axis of rotation, the direction of the axis of rotation.

它给出了这个旋转的角速率，有一个因子2，但没关系，给出了旋转轴，和旋转轴的方向。
