In this study, we systematically investigate the α decay preformation factors, Pα, and the α decay half-lives of 152 nuclei around Z = 82, N = 126 closed shells based on the generalized liquid drop model (GLDM) with Pα being extracted from the ratio of the calculated α decay half-life to the experimental one. The results show that there is a remarkable linear relationship between Pα and the product of valance protons (holes) Np and valance neutrons (holes) Nn. At the same time, we extract the α decay preformation factor values of the eve...
