英文摘要	The pedestal structure of the high-confinement mode (H-mode) operation strongly impacts global confinement and fusion performance in tokamak devices. Studies of the pedestal structure also play an important role in better understanding the characterization of H-mode plasma discharges with type-I edge localized modes on the Experimental Advanced Superconducting Tokamak (EAST). The EPED model has been widely validated to predict the pedestal structure of several tokamak devices. The mean pedestal width Delta(psi) correlates with the square root of the poloidal pedestal beta beta(1/2)(p,ped) and is in good agreement with Delta(psi) = 0.12 beta(1/2)(p,ped) from experimental observations. It is also found that the scaling coefficients of Delta(psi) and beta(1/2)(p,ped) may have no dependence on the heating schemes. The comparison of predictions with measurements indicates that the REPED model could be used to predict the pedestal height for a range of experimental pedestal pressures (1.7 < p(ped) < 2.6 kPa) on EAST.
