Around the dark core of an optical vortex, the energy flow carried by the light beam is like a spiral staircase, flowing in a clockwise or counterclockwise direction.
绕着光涡旋的黑暗中心，光束携带的能量流就像螺旋梯，沿着顺时针或者逆时针方向流动。

As in the incompressible flow, the Field and Matter Bicharacteristics of Vortex also have been demonstrated.
如同不可压流动，在可压缩流动中旋涡同样具有场与物质两重特征。

The flow rule and energy separation phenomena happened invortex tube are unconventionally complex.
