| 英文摘要 | Research shows that there is an asynchronous evolution process between the internal transport barriers (ITBs) formed in three channels (ion temperature, electron temperature, and density). Under the condition of a low toroidal magnetic field ( Bt similar to 1.6 T), the electron density ITB is the easiest to implement through the fueling effect of the first neutral beam injection with the least heating power. However, the ne ITB appears to be independent of heating power. The ion temperature ITB can be formed without reaching the threshold power under the condition of strong E x B shear flow, while maintaining ITBs in ion and electron channels simultaneously requires higher heating power. Moreover, the foot of the Ti ITB formed in the strong E x B shear case is located outside that in the fishbone case, while the ITB strength remains almost unchanged. The fishbone activities do not always occur prior to ITB formation, as our previous results have shown, suggesting that there may be no direct relationship between the physical process of ITB triggering and fishbone activities. |
