本文讨论了天文潮主要分潮Ｍ_２、Ｓ_２、Ｋ_１、Ｏ_１对风暴潮和天文潮相互作用所引起的非线性效应水位的影响以及各种非线性项所作贡献．在天文潮和风暴潮都大的海域，天文潮分潮的影响是显著的；非线性项中以浅水效应项、风－水位效应项、底摩擦项对浅海风暴潮和天文潮相互作用中非线性效应水位的贡献比较明显，而平流项、气压梯度项的作用甚微．从数值研究的角度给出了一些新的结论和定量地证明一些已有的重要结论．
In this paper, we discuss the effects of the main tidal wave M_2, S_2, K_1, O_1 of the astronomical tide on the non-linear water level caused by the interaction between storm surge and astronomical tide as well as the contribution of various nonlinearities. In astronomical and tidal waves, the influence of astronomical tidal wave is significant. In the nonlinear term, the shallow-water effect, the wind-water effect and the bottom-friction term interact with shallow-sea storm surge and astronomical tide in central Africa The contribution of linear effect water level is obvious, while the advection term and pressure gradient term have little effect. From the point of view of numerical research, some new conclusions are given and some important conclusions have been proved quantitatively.
