摘要
研究磁化等离子体中短波漂移阿尔芬波涡旋结构．采用涡旋气体动力学模型，估计出等离子体涡旋湍流谱，并求出反常扩散系数．研究结果表明，涡旋湍流产生的反常扩散系数与扰动场振幅的平方根成正比．
The vortex structures for the short-length drift Alfven waves in magnetized plasmas are investigated.The turbulence spectra of Plasma vortex are estimated,and the anomalous diffusion coefficient is found using the dynamic model of plasma gas. The results show that the anomalous diffusion coefficient caused by the vortex turbulence is proportional to the square of the potential amplitude of the perturbation.
