摘　　要：We investigate the nonergodic Brownian dynamics in a collinear particle-coupled harmonic chain model,in which the chain is free at one end and fixed at the other end.The behaviors of the particle are mainly studied:the velocity thermalizes faster than the coordinate,and the asymptotic result depends on its initial coordinate preparation which is indeed a kind of the nonergodic behavior.
