摘要：
A multifractal-like representation for multi-time, multi-scale velocity correlation in turbulence and dynamical turbulent models is proposed. The importance of subleading contributions to time correlations is highlighted. The fulfillment of the dynamical constraints due to the equations of motion is thoroughly discussed. The predictions stemming from this representation are tested within the framework of shell models for turbulence. (C) 1999 Elsevier Science B.V. All rights reserved.
