| 摘 要： | 应用改进后的程序详细计算了不同径向扩散系数对低杂波电流驱动剖面分布的影响。通过计算发现:考虑径向扩散效应后，驱动电流分布变平展宽，电流驱动的分布随着扩散系数的增大逐渐向外层移动，由局域性分布演化成非局域性分布；驱动电流的大小和效率随着扩散系数的增大而降低。

| Abstract: | The modified code is used to calculate the radial diffusion effect on the lower hybrid current drive (LHCD) profile. The results indicate that the LHCD profiles are broadened and become flatten owing to the radial diffusion, and they move toward the edge region of the plasma and change from local to non-local profile with the increasing efficient of radial diffusion, but the driven current and the efficient of LHCD decrease as the efficient of radial diffusion increases. |
