实测混合浪波高分布特征值分析

Analysis of Characteristic Values for the Wave Height Distribution in Observational Mixed Waves

把实测混合浪波高分布特征值H(1/(10))/H和H(1/3)/H由瑞利分布得到的波高分布相应特征值(称理论值)比较,发现两者的差值与混合浪中涌、风浪波高之比有关.当比值较大时,实测混合浪波高分布特征值大于理论值;比值较小时,接近理论值。无因次波高的经验频率和理论频率以及平均波高的变化趋势都与比值大小有关。

In the paper , by comparing the statistical characteristic values of wave height distri-bution with the calculative characteristic values of wave height distribution, we have obtained the following results: When the specific value of surging wave height and wind wave, height in a mixed wave is larger, the empirical characteristic value of height distribution in the mixed wave is larger than the theoretical value. And when the specific value is smaller, the both are almost the same. The empirical frequency and the theoretical frequency of nondimension height distribution and the changing tendency of average height are in relation to the theoretical value.
