摘要
应用粒子输运的模式来研究Fokker-Planck方程求解电子分布函数的关系,得到了电子输运分布函数与扩散系数以及边缘损失的情况。计算表明:当扩散系数增大时,边缘损失,电子分布剖面都在相应的增大,在离轴加热时,其相应的剖面峰值在减小。
A distribution function of electron is researched with Fokker-Planck equation. The distribution of electron, diffusion coefficient and edge losing are gained. It is shown profile will be enlarge with the diffusion coefficient enlarge, its'peak that the edge losing and electron distribution profile is minished with off-axis fueling.
