摘要: In this paper, we elaborate the electric field excitation mechanism during L–H transition in JFT-2M tokamak. Using time derivative of Poisson's equation, models radial is examined. The sum loss-cone loss current and neoclassical bulk viscosity found to behave as experimentally evaluated that excites field. turbulent Reynolds stress only plays a minor role. wave convection produces negative at edge can be important explain ambipolar condition L-mode.
