| 中文摘要: |
| 采用实验粒子模拟方法,研究了同等振幅条件,不同斜传角度下,斜传低频阿尔芬(Alfvén)波的加热；分析了加热过程中,质子动力学温度随斜传角度的变化,以及X、Z方向上粒子运动规律.模拟结果表明:低频阿尔芬波斜传角的增加会强化相混,从而有利于加热效率的提升；相混的提升是由于斜传加热在平行方向上产生的不均匀性导致的. |
| 英文摘要: |
| In this article,we use test particle simulation by the heating of magnetized plasma obliquely propagating low frequency Alfvén waves in different angle and with the same amplitude.During the heating process,we analyze the proton kinetic temperature and particle situation in X and Z direction with the change of propagating angle.It shows that:With the evolution of heating,obliquely propagating low frequency Alfvén wave will strengthen phase randomization process and cause the heating efficiency improvement.The reason for phase randomization improvement is that obliquely propagating low frequency Alfvén wave will turn to asymmetry in parallel direction. |
