采用最小二乘法,先对越南从北至南的33个沿海验潮站的长期观测资料(最少是5年,最多是53年)进行潮汐调和分析得到各站的调和常数,再根据分潮O1、K1、H1的振幅值计算V=(HO1+HK1)/HM2,然后结合各站的V值和实际观测资料,指出:越南北部沿岸潮汐性质为正规全日潮,潮汐振幅在2.5~4.5 m范围内;越南中部沿岸潮汐性质较复杂,该海岸具有3种潮汐类型,潮汐振幅较小大概0.5~2.5 m范围内;越南南部沿岸潮汐性质为不正规半日潮,潮汐振幅是3.0~4.0 m左右;越南西南部沿岸潮汐性质为不正规日潮,潮汐振幅大概是1.0~2.0 m范围内。
Based on the least squares method, the harmonic constants of each station are obtained from the long-term observation data of 33 coastal tide gauge stations from north to south in Vietnam (minimum 5 years and maximum 53 years) , K1 and H1, V = (HO1 + HK1) / HM2, and then combined with the V values of each station and observed data, it is pointed out that the tidal properties of northern coast of Vietnam are normal full tide and the amplitude of tidal range is 2.5-4.5 m The tidal properties of the central coast of Vietnam are more complicated. The coast has three types of tides with tidal amplitude of about 0.5-2.5 m. The tidal properties of the south coast of Vietnam are irregular semi-diurnal tidal amplitude of 3.0-4.0 m. The tidal properties along the southwestern coast of Vietnam are irregular diurnal tide, and the tidal amplitude is about 1.0 ~ 2.0 m.
