摘要：

It is pointed out within the framework of Kolmogorov and Obukhov's refined similarity hypothesis that the 1D surrogate of energy dissipation rate in isotropic turbulence, which has been conventionally used by many experimentalists to investigate intermittency in isotropic turbulence, leads to an unrealistic prediction of the probability density function of velocity gradient. This suggests that any discussion of intermittency of turbulence based on the 1D surrogate may be of a more or less qualitative nature.
