It is found that the growth rate of the current diffusive ballooning mode is decreased by the reduction of the geodesic curvature driving force. The reduction of thermal conductivity in the limit of very weak shear or negative shear in comparison with standard shear is also shown.}, title = {Current Diffusive Ballooning Mode in Seecond Stability Region of Tokamaks}, year = {1993} }
