摘　　要：从通常的局部输运模型的角度分析 ,托卡马克等离子体中有相当多的输运现象会被视为“奇怪”的或“反常”的 ,既难于被正确地理解 ,也难于给出统一的描述方式。基于温度剖面不变性的—这里称之为相容热导模型的描述方法 ,在不涉及非局部输运任何具体物理机制的情况下 ,给出了包含非局部效应的热导系数及其与局部反常热导系数的关系。利用这种相容热导模型统一地描述并分析了一些看似奇怪或反常的输运现象。Quite a few transport phenomena in tokamak discharges are looked upon as 'strange' or 'anomalous' ones from the viewpoint of the traditional local transport models,and,thus,are hard to be understood correctly and described concertedly in the scope of this kind of models.With the so-called,here,compatible model of the thermal conduction,which is based on and compatible with the temperature profile consistency,non-local transport effect and its connection with local anomalous thermal conduction can be given without touching upon any particular physical mechanism.Using the compatible model of the thermal conduction,some 'strange' or 'anomalous' transport phenomena in tokamak plasmas are described and analyzed concertedly.
