摘要: A new idea of scaling for transient phenomena near the instability point is proposed. This theory based on a generalized scale transformation time and very useful in discussing relaxation fluctuation non-equilibrium systems asymptotically unstable point. The whole range divided into three regions: initial regime which ordinary £-expansion valid, enhance ment occurs evolution equations functions are obtained, final system approaches equilibrium state. As an example, nonlinear Fokker-Planck equation studied by help present theory. possibility applications this general to various kinds pointed out.
