在理想双绝热磁流体力学方程组的框架内，研究了具有环向流和极向流的轴对称等离子体的稳态平衡问题。这个问题被减少到一个非线性偏微分方程的极向磁通量函数，包含六个表面功能，加上一个非线性代数伯努利方程定义的等离子体密度。在小β极限下讨论了椭圆性条件及其解的分支，适用于托卡马克平衡。与L-H过渡的可能连接的建议。
The stationary equilibrium of an axisymmetric plasma characterized by toroidal and poloidal flows is considered within the framework of ideal double adiabatic magnetohydrodynamic equations. The problem is reduced to a nonlinear partial differential equation for the poloidal magnetic flux function, containing six surface functions, plus a nonlinear algebraic Bernoulli equation defining the plasma density. Ellipticity conditions and bifurcations of its solutions are discussed in the limit of small beta, appropriated for tokamak-like equilibria. Possible connections with the L-H transition are suggested.
