摘　　要：　用有限差分隐式方向交替(alternatingdirectionimplicit,ADI)法求解潮波方程,并进行数据同化的数值试验,与未经同化的ADI法计算值相比有较好的效果.结果表明,采用数据同化系数1 12×10-4s-1为最佳选择.ADI (Alternating Direction Implicit) method is used to solve tidal wave equation and data assimilation numeric trial experimentation is performed. Compared with the results obtained by ADI method, the assimilated results have better improvement. It is shown that the optimal choice of the assimilation coefficient is 1.12×10^(-4) s^(-1).
