在這篇論文當中，我們引用`海岸綠堤--水筆仔'網站上的研究資料並且藉由Matlab程式軟體的幫助建構數學模型，我們討論以下的二階非線性微分方程
(i) u''(t)=f(u(t)), u(t_0)=u_0, u'(t_0)=u_1.
(ii) u''(t)=f(u'(t)), u(t_0)=u_0, u'(t_0)=u_1.
我們比較拋物線函數，立方函數，傅立葉和函數，正弦和函數並且從這些函數中選出最好的一個當作我們的模型，我們得到一些主要的結果。 / In this paper, we use the real data from website of `Seacoast Green Bank--Kandelia' and construct mathematical models with the help of Matlab, we discuss the following nonlinear 2nd order differential equation
(i) u''(t)=f(u(t)), u(t_0)=u_0, u'(t_0)=u_1.
(ii) u''(t)=f(u'(t)), u(t_0)=u_0, u'(t_0)=u_1.
We compared with the functions of parabolic, cubic, Fourier summation, sum of sine and choose the best one from them as our model, we have obtained main results.
