采用正交响应法将华南地区TOPEX/Poseidon卫星高度计数据（6年248个周期）数据同化为潮汐模型。给出了最佳开放边界条件和底部摩擦系数，以及m 1 和M 2 的潮汐图。与59个验潮站数据结果相比，m 1 分量的振幅和相位滞后计算值与实测谐波常数的平均绝对误差分别为4.8cm和8.7°，M 2 分量的平均绝对误差为4.3cm和11°。数值模拟的结果与验潮仪的结果一致。说明该方法是有效的。
Assimilated the data, which from TOPEX/Poseidon satellite altimeter data (248 periods lasting six years) in the South China basing upon orthogonal response method, into tides model by using adjoint method. Optimal open boundary conditions and bottom friction coefficient were given, the cotidal charts for m 1 and M 2 as well. Compared with the result from the data of 59 tide gauge stations, the average absolute error for m 1 constituent between the computed and the observed harmonic constants are 4.8cm and 8.7° for amplitudes and phase lags respectively, there are 4.3cm and 11° for M 2 constituent. The results in the numerical simulation coincide with tide gauges. It shows that the method is valid.
