剖面不变性、反常电子热导及托卡马克装置约束性能分析

PROFILE CONSISTENCY, ANOMALOUS ELECTRON THERMAL CONDUCTION AND ANALYSIS OF CONFINEMENT OF TOKAMAK DEVICES

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。

Assuming that there exists a position in the tokamak plasma where the energy transport is dominated by local anomalous electron thermal conduction and taking advantage of the basic experimental result usually called as profile consistency, we obtain a more convincing approach to the describtion of the confinement property of tokamak devices without touching upon the physical mechanism of global plasma energy transport.
