摘　　要：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。Starting from the four fluid equations which can simply and effectively describe the motion of trapped particles,the eigenmode equations and the relevant dispersion relation for the m=1 internal kink modes are derived,which include the effects of trapped particles,diamagnetic drifts,finite resistivity and anomalous electron viscosity.Using the above results,the influence of the trapped particles and various dissipative effects on the instabilities of the m=1 internal kink modes are analyzed in the cases with and without energetic alpha particles in the plasma core.
