  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.
