摘要
证明了在一个适当稠密但却有限的结点集上，若已知阻尼ＲＬＷ方程周期解的渐近性，则这个解自身的渐近性可被完全确定．并给出了确定解的渐近性所需结点数目的一个上界估计．
It is proved that if the asymptotic behavior of the periodic solution for damped RLW equation is known on a sufficiently dense set(but finite),then the asymptotic behavior of the solution itself is totally determined.An upperbound is given for the number of nodals needed to determined the asymptotic behavior of the solution.
