angular rotation

The boundary layer is a very narrow region between an accretion disk and an accreting star, in which with the disk material approaching the surface of the star its angular velocity drops from the Keplerian value to the angular rotation velocity of the star.

边界层是介于吸积盘和吸积星之间的非常狭窄的区域，在该区域中随着盘物质接近星面，它的角速度从开普勒角速度下降至恒星自转角速度。

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。
