本文用协方差函数法探讨了海浪谱的估计方法。黄海A站海浪谱系由441B—Ⅲ型电子计算机算出的。本文论述了下列一些问题:1.据一系列离散采样资料计算协方差函数和海浪谱;2.用Hanning权函数平滑协方差函数和用Hanning谱窗函数平滑海浪谱;3.计算海浪谱的置信区间;4.提出了海浪谱的无因次公式及其参数值;5.其他。 In this paper, the covariance function method to explore the wave spectrum estimation method. Yellow Sea Station A wave spectrum by the 441B-Ⅲ type of computer calculated. This article addresses the following issues: 1. Computes covariance and sea wave spectra from a series of discrete samples; 2. Smooths the covariance function with the Hanning weight function and smoothes the wave spectrum with the Hanning spectral window function; 3. Calculates the confidence of the sea wave spectrum Interval; 4. Proposed a no-dimensional formula of the wave spectrum and its parameter values;
