研究了任意截面有限剪切托卡马克的气胀不稳定性。这些方位角定域的理想磁流体动力模态具有较大的环面模态数，但沿磁场和通量面变化有限。在适当的边界条件下，通过求解每个通量表面上的二阶常微分方程来确定稳定性。定性一致与普林斯顿害虫稳定性规范。
We studied ballooning instabilities in tokamaks of arbitrary cross section and finite shear. These azimuthally localized, ideal magnetohydrodynamic modes have large toroidal-mode numbers, but finite variation along the field and across the flux surfaces. Stability is determined by solving a second-order ordinary differential equation on each flux surface, subject to the proper boundary conditions. Qualitative agreement is achieved with the Princeton pest stability code.
