Nondimensional parameter dependence of heat transport between edge localized modes (ELMs) is examined for H mode plasmas. The electron heat diffusivity between ELMs is reduced to the level of ion neoclassical transport in the plasma edge region which is affected by ELM burst. At lower edge collisionality, the heat flux assigned to the heat transport between ELMs is reduced and the ELM loss power is enhanced. During the inter-ELM phase, the energy confinement time becomes larger with decreasing the edge collisionality and poloidal Larmor radius.
研究了H模等离子体中边缘局域模（ELM）之间热输运的无量纲参数依赖性。ELM之间的电子热扩散率降低到等离子体边缘区域受ELM爆发影响的离子新经典输运水平。在较低的边缘碰撞率下，分配给ELM之间热输运的热通量降低，ELM损失功率增强。在ELM间隔阶段，能量约束时间随着边缘碰撞率和极向拉莫尔半径的减小而增大。
