Abstract：A mo del of ring polymer chains, whose ends are physical adso rbed or chemical combined by some impermeable w alls, w alk randomly on lattice is made .The generation probability PN of ring polymer chain is theoretical analy zed and computer simulated.The relation between the av erage ring chain length < N > and the max imum ring chain leng th Nmax of ring polymer chain is discussed .The results show that the generation probability can be ex pressed approximately as PN a ·N-1 .5 and the averag e ring chain leng th is linear with the maximum ring chain leng th .
