研究了m/n = 2/1新经典撕裂模式的发生条件，包括新经典驱动、触发不稳定性和在球形环面NSTX中的环面旋转或旋转剪切（Ono m . et al . 2000）。Fusion 40 557)。这些模式有三种典型的开始条件，按照模式开始所需的新古典驱动的增加顺序给出：由高能粒子模式触发，由边缘局域模式触发，以及模式似乎在没有触发的情况下生长。在所有情况下，所需的驱动增加了环面旋转剪切，这意味着剪切的稳定效果。
The onset conditions for the m/n = 2/1 neoclassical tearing mode are studied in terms of neoclassical drive, triggering instabilities, and toroidal rotation or rotation shear, in the spherical torus NSTX (Ono M. et al 2000 Nucl. Fusion 40 557). There are three typical onset conditions for these modes, given in order of increasing neoclassical drive required for mode onset: triggering by energetic particle modes, triggering by edge localized modes and cases where the modes appear to grow without a trigger. In all cases, the required drive increases with toroidal rotation shear, implying a stabilizing effect from the shear.
