| 摘 要： | 本文介绍低杂波电流驱动模拟计算编码中福克－普朗克方程的数值求解。考虑了螺距角散射造成的高垂直温度效应（二维效应）和相对论效应。同时．福克－普朗克方程中包括了描述尾部电子约束的项。数值结果表明，二维效应和相对论效应的加入均能提高电流驱动效率。驱动电流随尾部电子约束改善而增加。

| Abstract: | A Fokker-Planck simulation model of lower hybrid current drive is presented. The high perpendicular temperature effect due to pitch angle scattering and the relativistic effect are taken into account. Also, a term describing the confinement of electron tail is included in the Fokker-Planck equation. The numerical results show that both the two-dimensional effect and the relativistic effect result in a higher current drive efficiency, and the driven current increases with the improved confinement of the electron tail. |
