计算了理想内弯折模的稳定性，考虑了外区和奇异层中热离子的动力学响应。通过扩展无碰撞色散关系，包括平衡径向电场，它被发现的内部扭结模式的稳定性敏感地依赖于剪切环形等离子体旋转。剪切环形等离子体旋转可以增加内部扭结模式位移的临界压力通常由一个因素的两倍。
The stability of the ideal internal kink mode is calculated, taking into account the kinetic response of thermal ions in the external region and the singular layer. By extending the collisionless dispersion relation to include the equilibrium radial electric field it is found that the stability of the internal kink mode depends sensitively on sheared toroidal plasma rotation. The sheared toroidal plasma rotation can increase the critical pressure for internal kink mode displacements typically by a factor of two.
