摘要：

The inertial range scaling exponents zeta(p) for the velocity difference moments [[u(x+r)-u(x)](p)] in high Reynolds number turbulence are considered for large values of p. Two different models are considered. In the first the asymptotic behavior of zeta(p) is 1.440(1/2), and in the second it is (p/9). It is shown that these two models are indistinguishable experimentally for p<100, but that the underlying dynamical assumption about the most intense turbulent events in the two models is essentially different.
