Abstract： We investigate the collapses and revivals of the interacting Bose--Einstein condensate based on the coherent state description of the condensate. Our research shows that the revival time is larger than the previous predication [Phys.Rev.Lett.77(1996)2158] when the high-order expansion of the chemical potential is considered. In particular, we predict an obvious damping effect in the process of collapses and revivals of the condensate.
