In order to solve the problem of poor mirror polishing effect of steel used in plastic die， the polishing efficiency of die steel is improved by optimizing smelting process. The results showed that the mirror effect was closely related to the purit

This paper explores the fundamental cosmological principle, with a specific focus on the homogeneity and isotropy assumptions inherent in the Friedmann model that underpins the standard model. We propose a modified redshift model that is based on the
