| 摘 要： | 讨论了由径向电场产生的剪切极向流对托卡马克中等离子体的约束的影响。采用考虑了剪切极向转动效应的新经典离子热输运系数模型，这种模型导致的热通量函数在相同的密度和温度下是多值的，将它用于电子与离子之间有碰撞的ＭＨＤ方程，数值结果显示了Ｈ模情形等离子体上边缘陡峭的离子温度梯度。

| Abstract: | Radical electric fields may play an important role in L H transition. The influence of sheared flows induced by radical electric fields on the confinement of plasma in Tokamak is discussed in this paper. A neoclassical ion heat transport coefficient model is adopted, in which the effect of sheared poloidal rotation is taken into account, and the heat flux function has multiple values with the same plasma density and temperature. This model is applied to MHD equations, with the numerical result showing that there is a sharp temperature gradient at the plasma edge in the situation of H mode. |
