摘　　要：研究半空间中具有一般边界条件的广义BBM-Burgers方程在流函数是一般非线性光滑函数且初始扰动大的条件下边界层解的渐近稳定性,并导出此初边值问题的解渐近收敛到边界层解的一个指数收敛率,从而澄清了一般边界条件对收敛率的影响.Asymptotic stability of boundary layer solutions for generalized BBM-Burgers equation with general boundary data and general smooth nonlinear flux function in a half space under the condition of large initial perturbation is concerned. An exponential time decay rates of solutions toward boundary layer solutions is derived for this initial boundary value problem. This clarifies the effect of general boundary data on the convergence rate.
