| 摘 要： | 针对海道测量中在同一验潮点人工水尺与压力式水位计同步水位观测所得不同的潮位数据,分别绘制潮位曲线,从两条相关的曲线数据中应用三次样条和拟合数学函数模型,利用计算机程序确定曲线间的线性关系,从而根据压力式水位计测得的数据确定的关系得出真实的潮位数据。

| Abstract: | Based on the tidal data gained synchronously both form manual water level gauge and pressure type water gauge in the same observing station,this paper respectively puts out different curves.Cubic spline function and fitting mathematic function model are used in data process of the two related curves.The linear relationship of the curves is determined by using computer program.Thus,according to the data from pressure type water gauge,the relationship and the real tidal data are obtained. |
