The fine structure of the isotropic turbulence, which has recently been realized in asupercomputer by the authors, is studied at its fully-developed state. The geometricalrelationship between vorticity-concentrated regions and high-strain regions and avariety of mutual orientations of the velocity and vorticity vectors in these regions areillustrated. A common exponential nature and a delicate difference of the spacedistributions of the velocity (longitudinal and lateral) gradients, along with themagnitude of vorticity and the square-root of local dissipation, are exposed.
