利用无粘、不可压涡旋流的稳定性分析的理论结果，计算了破碎涡内部流动的振动频率，与实验值相符合。
By using the theoretical investigations of the stability of a incompressible swirl flow, the oscillating frequency is calculated. The result is in a good agreement with experiments.
充分说明龙卷风由涡旋流和急流这两种流叠加而成，涡旋流是由惯性离心力造成的，急流是由水平辐合辐散而引起的强对流。
The vortex flow is resulted from inertial centrifugal force and the jet flow is from strong convection by the horizontal convergence.
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。
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.
