主　　题：isotropic turbulence structure function EES scaling exponent 

摘      要：Theoretical results on the scaling properties of turbulent velocity fields are reported in this *** on the Kolmogorov equation and typical models of the second-order statistical moments (energy spectrum and the second-order structure function),we have studied the relative scaling using the ESS *** is found that the relative EES scaling exponent Sis greater than the real or theoretical inertial range scaling exponentξ,which is attributed to an evident bump in the ESS range.
