The most significant feature in the cosmic-ray (CR) nuclei spectra is the spectral hardening at a few hundred GV. It is important to know whether the hardening of different nuclei species is the same or not for constructing CR sources and propagation models. In this work. we collect the recently released AMS-02 CR nuclei spectra of primary species (proton. https://citylocers.shop/product-category/mario-lopez/
