| 摘 要： | 本文利用低混杂波电流驱动的准线性理论模型，研究了由于磁场的随机涨落而引起的快电子的反常输运对驱动电流分布和驱动效率的影响。结果表明，高能电子径向扩散将使驱动电流分布变平和展宽，同时驱动电流减小。

| Abstract: | By using the quasilinear Fokker-Planck model, radial diffusion effects on the drive current profile and driving efficiency of lower hybrid current drive (LHCD) in the HL-1M tokamak are studied with anomalous transport of fast electrons taken into account. It is shown that the radial diffusion of fast electrons leads both to a broadening of the driven current profile and to a reduction of the total driven current. |
