摘要
本文提出了研究Transition区谱分布的静电模型,并按等离子体弱耦强湍理论对其重正化得到了谱方程.对谱方程作适当近似后,证明了该近似谱方程存在扰动密度谱为k^(-5),扰动电场谱为k^(-3)分布的解,从而定量解释了Transition区的实验谱分布结果.
In this paper, an electrostatic model for transitional domain of ESF is derived from plasma two-fluid equations, then, its spectrum equation is obtained according to the weak coupling approximation formalism of plasma turbulence. It is shown that this model has k-5 and k-3 type spectrum for plasma density fluctuation and electric field fluctuation respectively which agree well with the ESF transitional domain's experimental results.
