The decaying isotropic turbulence starting with a typical initial energy spectrumwas numerically investigated by the spectral method for Reynolds numbers 50-500,using up to 128' grid points. The microscale Reynolds number reached at a fully devel-oped state was< 100. Only the periodic boundary condition was set on the surfacesof the cube which contained the turbulence. As a result, the Kolmogorov spectrumlaw and other interesting characteristics of the turbulence were found, including theperspective of intermittent strong-vorticity regions randomly distributed in a fully de-veloped turbulence.
