在磁轴附近分析了电阻气球模。有两个模式分支，一个连接到通常的撕裂模式，另一个连接到磁流体动力学气球模式。不稳定模满足广义撕裂色散关系。电阻气球模式在很宽的β范围内可能是不稳定的，但可以通过交换效应和有限的声速来稳定。分析结果与低模态数值解定性一致。
Resistive ballooning modes are analyzed in the neighborhood of the magnetic axis. There are two mode branches, one connecting to the usual tearing mode and the other to the magnetohydrodynamic ballooning mode. Unstable modes satisfy the generalized tearing dispersion relation. Resistive ballooning modes can be unstable for a wide range of beta, but may be stabilized by interchange effects and finite sound speed. The analytic results are in qualitative agreement with low mode number numerical solutions.
