摘要
OVER three decades, since the wide applications of the soliton phenomena in almost all the physical fields, the theoretical, experimental and applied studies of the soliton have become an active research topic. The direct macro-observation of the soliton phenomana is one of the important problems. Since the observation of Wu et al. on the nonpropagating fluid solitons in 1984, the nonlinear systems on the vibratmg table have offered us a good experimental field. Some nonlinear excitations of the macro-monatomic lattice have been observed by Denardo et al. Ref. reported the observation of the localized structure of the granular sys-
