This article gives an overview of the significance of polymer science, course and the development of current researches at home and abroad. The adsorbed ring polymer chains have special performance and behavior because of its special structure. The work bases on the simple cubic lattice model and enumeration calculation method to calculate the mean-square radii of gyration, the heat capacity, the average Helmholtz free energy and the shape factor of the adsorbed ring polymer chains, and then obtain the shape, size, thermodynamic properties as a function of temperature and the phase transformation for adsorbed ring polymer chains.
