摘要
A model is presented based on the combined effects of m/n = I magnetic island dynamics, localized heat sources, large heat diffusivity along magnetic field lines, and plasma rotation, which may explain the multipeaked temperature profiles and transport barriers observed in tokamak plasmas heated by electron-cyclotron-resonant waves.
