摘要
Recent progress in experimental investigations, related to the determinant variables of the GH transition, is reviewed in this paper. In particular, it is put forward that the 'wall effect', which often produces spurious contributions to the various parametric dependences of the H-mode threshold power, may be an embodiment of the atomic processes, involving the edge neutrals as a 'hidden' variable. In addition, relations between the edge plasma quantities and threshold scaling are emphasized, quoting the ostensibly different observations in various tokamaks.
