corotation

Partition setting winding corotation and kickback.

分段设定绕线正，反转。

The corotation circle acts as an interface that can either reflect or transmit these waves, allowing them to gain energy at the expense of the global rotational kinetic energy of the galaxy.

共同旋转圈作用，像个可以反射或透射这些面，让它们转换星整体转动动能能量。
