摘　　要：根据宁波北仑海域的连续3a的实测风浪资料,讨论了在不同风速条件下波高分布和周期分布,以及两者的联合分布;通过与理论结果的比较,得出波高分布与Rayleigh分布基本符合,但有一些差异,周期分布与孙孚的理论周期分布较符合,而波高与周期的联合分布除了图形的形状以及大波对应的无因次周期的值与孙孚的理论值有差异外,两者吻合较好。According to the measured data of sea waves at Beilun sea area of Ningbo for three years in succession, the distributions of wave heights and wave periods, and the joint distributions of wave heights and periods, with differ ent wind velocities. Compared with the theoretical results, it is shown that the distributions of wave heights arc in keeping with Rayleigh's except a few differences, and the distributions of wave periods are identical with the theoretical results of Sun Fu. Apart from the figures and values of periods with no dimension corresponding the great waves, the joint distributions of wave heights and periods are quite consistent with Sun Fu's results.
