The phenomenon of aliasing is examined by supposing the samples are taken at intervals of exactly 6 lunar hours. The constituents with frequencies satisfying the relation(σ_1±σ_2)=2σ_(M_2) are inseparable and the coefficient determinant of the normal equations will be singular if the heights only are used.

With the application of electronic computers, the extraction of harmonic constants from high and low waters becomes an extremely simple process compared with Doodson's technique. The phenomenon of aliasing is examined by supposing the samples are taken at intervals of exactly 6 lunar hours. The constituents with frequencies satisfying the relation(σ_1±σ_2)=2σ_(M_2) are inseparable and the coefficient determinant of the normal equations will be singular if the heights only are used. When the values of the first derivatives and the irregularity of the sampling are taken into consideration the condition of the determinant is improved. Large diurnal tides can cause irregularity of sampling and so we are in favour of the separation of the aliased constituents. For tidal current data, if the slack times are available, the results of analysis can be much improved. The results far major constituents derived from the observed high and low waters agree satisfactorily with those from hourly data.

本文给出了由高、低潮数据计算潮汐调和常数和由最大流速及转流数据计算潮流调和常数的方法。文章还讨论了不同频率分潮间的混淆效应,指出本方法用于混合型和全日型潮汐可获得比半日型潮汐好的效果。对两个港口实测高、低潮数据分析表明,所得调和常数与由逐时潮高分析所得的数值一般较接近,但对长周期分潮较差。本方法所得调和常数用于预报高、低潮或最大流速和转流时可得到很好的结果。
