本文证明了：（a）描述具有纯极向流和任意截面形状的圆柱形等离子体平衡态的理想磁流体动力学方程[G. N. Throumoulopoulos和G. Pantis，Plasma Phys.Controlled Fusion 38，1817（1996）]，对于轴向速度分量为自由表面量的不可压缩平衡流也是有效的，并且（B）对于等温不可压缩平衡的情况，磁性表面必须具有圆形横截面。
It is proved that (a) the solutions of the ideal magnetohydrodynamic equation, which describes the equilibrium states of a cylindrical plasma with purely poloidal flow and arbitrary cross-sectional shape [G. N. Throumoulopoulos and G. Pantis, Plasma Phys. Controlled Fusion 38, 1817 (1996)], are also valid for incompressible equilibrium flows with the axial velocity component being a free surface quantity and that (b) for the case of isothermal incompressible equilibria the magnetic surfaces necessarily have a circular cross-section.
