摘要：

In order to reveal the underlying statistics properly describing fully developed turbulence, the probability density function of the local dissipation is determined by taking the extreme of a generalized entropy (Tsallis entropy). With the density function, the scaling exponents zeta (m) of the velocity structure function are derived analytically. It is found that these scaling exponents are consistent with experimental data. The asymptotic expression of zeta (m) for m >> 1 has a log term.
