摘　　要：用普遍能量原理分析了托卡马克中具有各向异性高能飞行粒子成分等离子体对m=1,n=1内扭曲模的稳定性,发现刚刚飞行的高能粒子对此模能提供稳定作用,并比较了高能俘获粒子和高能飞行粒子对内扭曲模稳定作用的异同及其物理图象。The stability of m = l n = l internal kink mode in tokamak plasma with anisotropic energetic circulating particle component is analyzed by using the generalized energy principle. The stabilizing effect from the barely circulating particles is proved. The similarity and difference of the stabilizing effect on the internal kink mode from the energetic trapped particles and energetic circulating particles are compared, based on physical picture.
