摘　　要：本文列出了用19年以上验潮资料计算的中国和日本沿海的交点分潮和半交点分潮以及周期为三分之一太阳年分潮的振幅和迟角,分析了这些分潮在中国和日本沿海的分布特征。得出了以下结论:在中国和日本沿海交点分潮的振幅随地理纬度的增大而增大,半交点分潮在中纬度海域最大;三分之一太阳年分潮在中国沿海随地理纬度的减小而增大,日本西海岸振幅小于东海岸。从分析的交点分潮和半交点分潮可看出,在日本的南方某些岛屿的水位受到黑潮流量的影响,使得年和月的平均水位会出现异常。The harmonic constants of MN, MSN and Sa3 along the coast of China and Japan are obtained by analysing a set of tidal data for two decades. The amplitude of MN gets larger while the latitude increases; the amplitude of MSN is largest at middle latitude along the coast of China and Japan. The amplitude of Sa3 at China coast decreases as the latitude increases and it is smaller at Japan's west coast than east coast. Owing to the effects of Kuroshio on the sea level measurement at some islands in southern Japan, the annual-and monthly-MSL value may be abnormal as derived from short period data obtained from the area.
