Abstract反常输运现象是实验室等离子体和空间等离子体中的重要过程,该文运用量纲分析方法研究了无碰撞磁化等离子体的反常输运性质,得出反常电导率,反常扩散系数,背景物理量之间的明显关系式,结果表明,反常扩散系数具有玻姆扩散系数形式,反常热导系数具有NaTa/eB形式,电导率表达式也符合实验结果.
Other AbstractAnomalous transport phenomena are important processes in laboratary,astrophysics and space plasmas.Using quasilinear theory this article has studied the anomalous transport properties of the collisionless magnetized plasmas and obtained the matrix formula of the Anomalous resistivity,particle diffusion and heat diffusivity.Applying dimension method,the explicit relationships between Anomalous transport coefficients and background physical variables are made out.It is found that.Anomalous particle diffusion and heat diffusivity have the form of which agree with observations.
