基于任意截面托卡马克的正则截面理论，建立了描述电子和离子等离子体温度的输运模型。与8种不同托卡马克实验数据的比较表明，该模型能够很好地模拟等离子体放电。基于对实验数据的分析和数值计算的结果，建立了等离子体小半径一半处相对温度梯度行为的标度。
A transport model for describing electron and ion plasmatemperatures is developed on the basis of the canonical profile theory for a tokamak with an arbitrary cross section. A comparison with the data from experiments on eight different tokamaks shows that the model is capable of adequately simulating plasma discharges. A scaling for the behavior of the relative temperature gradient at half the plasma minor radius is constructed based on both an analysis of the experimental data and the results of numerical calculations.
