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