摘　　要：在 TFTR及 TEXT等装置上观测到的边界电子冷脉冲的输运现象是通常基于局部热导的瞬态输运理论所无法解释的。利用一个与电子温度剖面不变性相容的且与在ρ =ρL(ρL ≈0 .7～ 0 .8)处的局部电子热导相关的非局部电子热导模型来描述边界冷脉冲引起的电子温度变化的瞬态过程 。The transport phenomena recently observed in the edge cold pulse experiments on TFTR and TEXT are hard to be understood from the usual transient transport theories based on the concept of local thermal conduction.In this paper,a non local thermal conduction model,which is consistent with the electron temperature profile consistency and related to the local thermal conductivity at the point ρ=ρ L (ρ L ≈0.7～0.8),is assumed to describe the transient response of the electron temperature to the edge cold pulse.And it is found that almost all of the main features of the edge cold pulse experiments can be qualitatively explained by this thermal conduction model.
