本文根据电子温度剖面不变性这一基本实验现象,通过分布量决定的广义对流能流的引入及其与局部量决定的局部反常电子热导关系的分析,在不涉及等离子体整体能量输运物理机制的情况下,给出了托卡马克装置约束性能更可信的描述方式。 Based on the basic experimental phenomena of invariance of electron temperature profile, the introduction of generalized convective energy flow, which is determined by the distribution, and the analysis of the relationship between local anomalous electron thermal conduction and local anomalies, Mechanism, a more credible description of the constraint performance of tokamak devices is given.
