| 摘 要： | 根据海洋负荷潮理论，海潮位移改正的计算取决于海潮模型和格林函数的选取，因此，针对不同的海潮模型和不同的格林函数分别计算了海潮位移改正，并且比较和分析了它们对海潮位移改正所带来的影响。结果表明，不同海潮模型和不同格林函数对海潮改正的计算值有一定的影响，而且相对来说，不同海潮模型所引起的差别较大，但是这种差别对GPS数据处理的最终结果影响不大。

| Abstract: | On the basis of theory of ocean loading tide, the computation of ocean tidal displacement corrections is dependent on the selection of ocean tide model and Green's function. Hence, with different ocean tide models and different Green's functions some ocean tidal displacement corrections are calculated and their effects are also compared and analyzed. The results show that different tide models and different Green's functions do have some effects on the calculation result. And comparatively, the difference caused by different tide models is greater than with different Green's functions. However this difference has little effects on the final result of GPS data processing. |
