摘要：

It is shown that toroidal-magnetic-field ripple-induced particle flux can drive poloidal E x B speed to bifurcate over the local maximum of the nonlinear poloidal (or parallel) viscosity. Here, E is the electric field, and B is the magnetic field. This mechanism, together with the turbulence suppression due to the radial gradient of the E x B and diamagnetic angular velocity, is employed to explain the enhanced reversed shear mode observed in the core region of tokamaks.
