摘      要：The Alfvenic cascade(AC ) mode is a branch of sheared Alfvenic modes localized at the magnetic surface with minimum safety factor(q ).Usually,a strong gradient region so-called internal transport barrier(ITB ) appears around the minimum q surface[1].The effect of pressure gradient on AC modes has been investigated by different authors,but their conclusions are contradictory to each other[2,3].In this
