摘要：

Hydrogen bubble techniques were improved to get information about the vorticity transfer. In particular, the method to see qualitatively the distribution of vorticity and the method to determine the vorticity in the vortex region were developed. By use of these methods, the mechanism of vorticity produced on the surface of the cylinder and fed to the vortex region and the mechanism of onset of turbulence in the vortex region were made clear in relation to the vorticity distribution and the flow patterns.
