非均匀等离子体湍流的重正化准线性理论(Ⅰ)——Misguich-Balescu理论的推广

本文将Misguich和Balescu的理论推广到非均匀等离子体的情形,导出了包括非均匀性效应的扩散方程与扩散张量的表式以及色散关系。指出Pelletier等人对等离子体湍流可作马尔科夫近似处理的论证完全不适用于非均匀等离子体湍流的问题。 关键词：

RENORMALIZED QUASI-LINEAR THEORY OF TURBULENCE IN NON-UNIFORM PLASMA (Ⅰ)——GENERALIZATION OF MISQUICH-BALESCU THEORY

In deriving the diffusion equation, diffusion tensor and dispersion relation in respect of the inhomogeneity in plasma, the Misquich-Balescu's theory on turbulence in uniform plasma can be generalized to the case of non-uniform plasma. It is indicated that the method given by Pelletier et al. in considering the plasma turbulence as a Markov process is now inadequate to describe the turbulence in non-uniform Plasma.
