摘　　要：By means of the Dirac procedure, we re-examine Yang＇s quantized space-time model, its relation to Snyder＇s model, the dS special relativity and their UV IR duality. Starting from a dimensionless dS3-space in a （5＋1）- dimensional Mink-space a complete Yang model at both classical and quantum level can be presented and there really exists Snyder＇s model, the dS special relativity and the duality.By means of the Dirac procedure, we re-examine Yang＇s quantized space-time model, its relation to Snyder＇s model, the dS special relativity and their UV IR duality.
