摘　　要：对含多资料的分潮波模型的超定问题进行探讨，建立一种有限差分—最小二乘方法，该方法使得岸边资料直接进入了计算方程，并保证岸界法向流速为零条件。通过对渤海的四大分潮的试算，证实本方法可行。In this paper a finite difference- least square method is put forward to solve the overdetermined problem of tidal wave. The final equations can be obtained under such a condition that the error of general verdetermined equations is the least.The method makes the calculations of tidal wave and tidal currents conform to reality. The computing of the four princlpIe components of the Bohai Sea (M2,S2,K1,O1)and the tidal currents proves that this method is feasible.
