海浪的条件特征周期
Conditional characteristic periods of sea waves

摘要: 在海浪波面高度为正态分布的假定下,导出一种以给定波高为条件的条件周期概率密度函数.与风浪槽中测量数据比较,结果表明,在窄谱情况下此概率密度函数与实验室风浪的实际符合良好.根据此密度函数定义了3种条件特征周期,并导出它们与平均周期的关系式.根据这些关系对有关海洋工程上的一些问题作了解释和讨论.

Abstract: A conditional probability density function of wave period,assuming wave height,is derived on the basis of normally distributed waves.Comparison between the density function and the data measured in a wind-wave tank shows a favorable agreement for waves of narrow-banded spectrum.Three conditional characteristic periods are defined and the relationships between them and the average period are derived from the density function.Interms of these relationships,some problems concerning ocean engineering are explained and discussed. -
