摘要：

It is shown that the probability density functions of velocity increments at small scale in turbulent flows turn to an universal (Gaussian) shape when conditioned to a precisely defined energy transfer rate epsilon(l). The standard deviation sigma(epsilon(l)) of this distribution depends on epsilon(l) following a Kolmogorov like relation sigma3 = C(epsilon(l)).l with a Reynolds number dependent coefficient C.
