摘要：

The q-th. order intermittency exponents and generalized dimensions of isotropic turbulence are calculated for │q│≦30 from the data of the direct numerical simulation, which was recently executed on the 1283 grid of a supercomputer to investigate a decaying isotropic turbulence. These values are compared with the theoretical and experimental values so far known. The corresponding f-α spectrum is also presented. © 1990, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
