相对论性非广延分布等离子体自生磁场方程

Equations of self-generated magnetic fields in relativistic plasmawith non-extensive distribution

磁场是等离子体中重要的非线性结构。有关等离子体中磁场的产生机制是等离子体物理学研究的重点课题,在激光等离子体及核聚变物理中有重要应用。近年研究结果表明,非广延分布函数在描述等离子体系统时更具优越性,现已成为国际研究热点。考虑波-波、波-粒相互作用,从弗拉索夫方程及麦克斯韦方程组出发,利用自生磁场理论,建立起相对论非广延分布等离子体中的低频磁场控制方程。

Magnetic field is an important nonlinear structure in plasma. The investigationon the generation mechanism of magnetic field is a key research topic in plasma physics,which can be applied in laser-plasma and nuclear fusion. The recent research demonstrated that the plasma with non-extensive distribution ha- dits superiority in describing the plasma system. It has become a hotspot in the international research field in recent years. The wave-wave and wave-particle interactions were considered.. equation and Maxwell equations, it established the low-frequency magnetic field sire distribution plasmaaccording to the self-generated magnetic field theory.
