首次将列率谱分析的两种谱估计方法：并矢周期图法和并矢相关法引入到随机海浪的研究。文中就不同环境条件下实验室资料，对两种谱估计方法进行了比较，结果表明：两种谱估计方法所得结果非常吻合。
For the first time, two spectrum estimation methods of column rate spectrum analysis are introduced: the parallel cycle diagram method and the parallel correlation method are introduced into the study of random wave. In this paper, we compare the two spectral estimation methods with laboratory data under different environmental conditions. The results show that the two spectral estimation methods are in good agreement.
