摘要：

Characteristics of the internal transport barrier (ITB) were studied. The region of steep del T-i and del V-t, i.e. the ITB front, propagated from the core outwards. The thickness of the ITB front was about 3 cm. The ITB worked as a particle transport barrier as well as a thermal transport barrier for ions. The threshold heating power for ITB formation strongly increased with electron density and was independent of the toroidal magnetic field. ITB with tau(E)/tau(E)(ITER89-P) approximate to 2.6 was sustained for twice the global energy confinement time tau(E). A repetitive relaxation phenomenon at ITB was observed, which induced D-alpha spikes like ELMs but had a different poloidal distribution.
