摘　　要：In this paper, the Large-time problem of generalized Burgers equations in twodimensions is considered, semidiscrete and completely discrete spectral approximations are constracted, and error estimates of optimal order that hold uniformly onthe unbounded time interval 0 ≤t＜ are obtained.In this paper, the Large-time problem of generalized Burgers equations in twodimensions is considered, semidiscrete and completely discrete spectral approximations are constracted, and error estimates of optimal order that hold uniformly onthe unbounded time interval 0 ≤t＜ are obtained.
