为了找出扰动磁场的大小对托克马克等离子体物理中增强的热导率及其径向分布的影响，数值研究了电子在随机磁场中的扩散。为此，我们选择了非局域随机磁场作为研究对象。从数值结果可以看出，无论是单岛磁场还是全随机场，扰动磁场大小对提高电子热输运电导率的影响都是主要的参数。给出了理论分析，并与数值结果进行了比较。
Electron heat diffusion across stochastic magnetic fields is studied numerically in order to find out how the magnitude of perturbed magnetic field affect the enhanced heat conductivity and its radial profile in tokomak plasma physics. For these purposes, non-local stochastic magnetic fields are chosen as research objects in our simulation work. From our numerical results, we can find that the effects of the perturbed magnetic field magnitude are dominated parameter on the enhance electron heat transport conductivity wherever the magnetic field is single island or full stochastic field. Also, a theoretical analysis is provided and compared with numerical results.
