摘　　要：Drift mode linear growth rate and quasi-linear ion thermal transport in the reversed magnetic shear plasma are investigated by using the two-fluid theory,previously developed by Weiland and the Chalmers group[J.Nucl.Fusion,29(1989)1810;ibid.30(1990)983].The theory is here extended to including both the radial electrical field shear(d E_(r)/dr)and the electron fluid velocity(V_(e))in the sheared coordinate system.Here,Ve describes the coupling between the safety factor q and the E_(r) × B velocity VE.Their influences on the growth rate and associated ion thermal transport are obtained numerically,In addition,the ion heat pinch in the reversed shear plasma is observed.Qualitatively,the present conclusions are in good agreement with the experimental results.
