摘要 考虑一维空间对流扩散方程(c)/(t)+u(c)/(x)=Dc_(xx)+c_(xt)-(c^2)_x解的L_p(2≤p≤∞)衰减估计,利用格林函数、频谱分析、能量估计等方法得到了解有与热核算子相同的衰减速度. This paper investigated the Lp estimates of solutions to one-dimensional convection-diffusion equationsc/t + uc/x= Dc(xx) + c(xt)-(c^2)x,using Green's function method,frequency decomposition and energy estimates.We found that the decay rate of the solution is the same as that for heat fusion operator.
