In this work , we considered 2 schemes ( a high-rigidity break in primary source injections and a high-rigidity break in diffusion coefficient ) to reproduce the newly released AMS-02 nuclei spectra ( He , C , N , O , Li , Be , and B ) when the rigidity larger than 50 GV .
The fitting results show that current data set favors a high-rigidity break at \sim 325 \mathrm { GV } in diffusion coefficient rather than a break at \sim 365 \mathrm { GV } in primary source injections .
Meanwhile , the fitted values of the factors to rescale the cosmic-ray ( CR ) flux of secondary species/components after propagation show us that the secondary flux are underestimated in current propagation model .
It implies that we might locate in a slow diffusion zone , in which the CRs propagate with a small value of diffusion coefficient compared with the averaged value in the galaxy .
Another hint from the fitting results show that extra secondary CR nuclei injection may be needed in current data set .
All these new hints should be paid more attention in future research .
