N2 - A unified model theory of the anomalous transport of high temperature plasma, L mode and H mode, is developed. Self-sustained turbulence theory for the pressure driven mode is extended, incorporating the effect of inhomogeneous radial electric field Er(r) to cover two electrically bifurcated states. Strong reductions of heat and current diffusivities, viscosity, the fluctuation amplitude, and correlation length are predicted in nonlinearly sustained turbulence. A consistent radial width of Er(r) is obtained. A new stability window is also found.
