利用描述俘获粒子运动的四流体模型推导出包含俘获粒子效应、离子反磁漂移、有限电阻及反常电子粘滞效应的ｍ＝１的内扭曲模本征方程和色散关系，并在等离子体芯部存在与不存在高能粒子的两种情况下，讨论了俘获粒子效应和各种耗散效应对内扭曲模的影响 A four-fluid model describing the motion of trapping particles was used to deduce the internal torsional mode eigenvalue equation and the dispersion relation of m = 1 with capture particle effect, ion diamagnetic drift, finite resistance and anomalous electron sticking effect. In both cases, the presence and absence of energetic particles, the effects of trapped particle effects and various dissipation effects on the internal twist modes are discussed
