摘　　要：通过求解二维Fokker Planck方程 ,得到了HT 7托卡马克低杂波驱动电流随时间的演化关系及其空间分布 ,理论值与实验结果基本符合 ,为HT 7托卡马克实验提供了理论依据 .通过解电流扩散方程 。Resolving the two dimensional Fokker Planck equation, evolutions of the driven current and its profile on HT 7 tokamak are obtained. The simulated results are nearly in agreement with the experimental data, which supplies a theoretical guidance for lower hybrid current drive (LHCD) experiments on HT 7 tokamak. In addition, the effect of radial diffusion of fast electrons on the driven current during LHCD is considered by means of solving the current diffusion equation.
