等离子体中粒子与cavitons相互作用

THE INTERACTION OF PARTICLES WITH CAVITONS IN PLASMA

从Vlasov-Poisson方程组出发,我们导出了电子慢变分布函数δF_e,慢变场E_s和快变场E之间耦合的动力学方程组,并在一维稳态下解析求解了这一方程组,从而获得了粒子分布函数与soliton作用关系;进一步讨论了高维下δF_e,E_s,E塌缩运动和它们的多个cavitons行为。

Starting from Vlasov-Doisson equations, the coupled dynamics equations for slowly varying electron distribution function δF_e, slowly varying field E_3 and fast varying field E are derived and the system of above equations is analytically solved. Thus, the interactions of the particles distribution functions with solitons are revealed. Furthermore, the collapse motions of δF_e E_3. E for higher dimensions and their many cavitons behavior are discussed.
