<正> 一、引言 本文提出的潮汐分析方法是在半图解法基本原理的基础上发展起来的一种方法。它利用34天的潮汐资料,依据坐标公式在“潮汐波面”上计算出720个非整点的潮高值,对这些潮高值分族后再按照严格的最小二乘法求得75个分潮的调和常数,得到了比较好的结果。

The method of the tidal analysis presented by this paper is the method which is developed on the basis of the semi-graphic method, making use of tidal data during 34 days. There are the magnitudes of tidal heights at 720 non-integral hours, which are taken off from the tidal "wave-surface" for the analysis. These magnitudes of tidal heights have been calculated in accordance with the coordinates of these points and by means of formula of the interpolation. At first, the magnitudes of tidal heights are divided into the species of the tide and then the harmonic constants for 75 constituents have been calculated strictly in accordance with means of the least squares method. According to this method analysed, the better results are given, for example, the mean squared error is calculated to be 5.78cm at Ogidigbe station.
