摘要：

A fast transport modelling code is applied to the transport profile database recently assembled by the ITER Transport Modeling and Database Group. Five published transport models currently in use are tested against a subset of DIII-D, JET and TFTR L and H mode discharges. The database provides little discrimination between the best fitting and the worst fitting models. Allowing for the fact that given experimental boundary conditions are critical elements of the models, it is shown that the present one dimensional transport models give only marginally better predictions than the ITER89P and ITER93H global scaling laws (GSLs). The difficulty of distinguishing the relative gyroradius (pr) scalings of transport models is discussed by focusing on the DIII-D dimensionally similar discharge pairs. There is a considerable difference in how the models project to ignition in ITER.
