摘要 对带Dirichlet边值条件的线性热传导方程初边值问题采用两层差分离散格式生成的离散动力系统,证明了离散系统在L2(Ωh)和H10(Ωh)上吸引集的存在性,并得出离散系统解的长时间稳定性与收敛性. In this paper, the descrete dynamic system for the initial-boundary value problem of one-dimensional heat conduction equations is generated by utilizing two level difference schemes, the existences of the attractor sets in L^2(Ωh) and H0^1(Ωh) for the descrete system are proved. Then the longtime stability and the longtime convergence are obtained for the descrete system.
