Besides the anomalous phenomenon on electron temperature profile, acceleration of the core toroidal rotation is also observed during the non­local transport process. The threshold of plasma density above which NLT disappears is also found related with LOC­SOC as other tokamaks. To understand the physic of NLT, some more signals are focused, including the radiation, magnetic fluctuation, temperature fluctuation. They are compared for the discharges with or without NLT, even for LOC and SOC. Some interesting phenomenon have been discovered, especially for the magnetic fluctuation. They may show the potential effect for NLT.
