DIAGRAM-ADDITION METHOD IN TURBULENT-PLASMA THEORY

摘要: This article suggests using for plasma-turbulence description a diagram technique analogous to the one suggested by Wyld hydrodynamic turbulence Such an approach enables abandon perturbation-theory limits used study of weakly turbulent pulsations and obtain approximate equations with aid which γ ≈ ω can be investigated.With this purpose in mind, precise solution Vlasov equation has been found some types turbulent-plasma magnetic field without assumption smallness pulsation amplitud. appearance infinite series powers potential electric field. Each term corresponding graphical picture. The further procedure obtaining plasma is many respects similar that ref. 1: expansion performed respect random as well averaging products potentials over Gaussian statistical ensemble addition subseries. resulting represent system number integral order functions. By way or another reasonable dis-continuity equations, closed finite finite-order obtained. In these approximate-equation systems constructed, representing certain analogy Kraichnan.
