本文详细计算了不同径向剖面的圆柱托卡马克中线性撕裂模的稳定性和径向分布。在趋肤电流分布的情况下，发现了径向磁场扰动中具有两个不连续点的“双撕裂模式”，并推导了一种分析方法，用于比较不同径向分布的稳定性。它进一步表明，撕裂模式可以驱动有限的电子粘度，以及通常的有限电阻率机制。
Detailed computational results are presented on the stability and radial distribution of linear tearing modes in cylindrical tokamaks of various radial profiles. In the case of a skin‐current profile, a “double tearing mode”, with two points of discontinuity in the radial magnetic field perturbation is found. An analytical method is also derived for comparison of the stability of different radial profiles. It is further shown that the tearing mode can be driven by finite electron viscosity, as well as by the usual finite resistivity mechanism.
