First, about the applications of the theory of random fields. One of the issues which we found interesting is the problem of non-universality of the local structure of turbulence. It is connected with the phenomena of intermittency, described in terms of break-down coefficients and multifractals. Special attention should be paid to the logarithmically periodic modulation (lacunarity) and to a physically distinguished scale factor (see E. Novikov, 1990, Phys. Fluids, A2 (5), 814). This scale factor leads to a generalisation of the concept of similarity and potentially to a deeper understanding of the internal mechanism of turbulent flows.
