以给定的闭合磁力线为磁轴，解析计算了闭合磁力线附近的磁力线。存在性的平衡，其旋转变换的磁轴是一个整数倍的½。将所得结果应用于主场扰动的托卡马克装置、φ = 2的仿星器、转动变换为零的平衡态的稳定性以及无净纵向电流和小转动变换的平衡态β值的标度。
Magnetic field lines near a given closed field line which is taken as a magnetic axis are calculated analytically. Existence properties are obtained for equilibria whose rotational transform on a magnetic axis is an integer multiple of ½. The results are applied to a tokamak with a perturbation of the main field, the ℓ = 2 stellarator, the stability properties of equilibria with vanishing rotational transform, and the scaling of the equilibrium β-value in configurations without net longitudinal current and with small rotational transform.
