摘　　要：研究半无限通道中,时变粘性流体Stokes流动时的空间衰减限和衰减率.得到了一个近乎最优的衰减率,且与Reynolds数无关.修正了Lin和Song的分析,选用更佳的任意常数得到衰减率为1.328,明显地改进了Lin得到结果0.91.Spatial decay bounds and a decay rate for the lime-dependent Stokes flow of a viscous fluid was investigated in a semiinfinite channel. It is shown how to obtain a near optimal decay rate that is independent of the Reynolds number. It is also shown that a modification of the analysis given by LinSong and a somewhat better choice of arbitrary constants yield the decay rate 1.328 which clearly improves upon that 0.91 obtained by Lin.
