| 摘 要： | 在对不同海域、不同海况和不同水深下测的大量海浪水压场数据分析的基础上,采用Epps-Pulley检验方法对海浪水压场信号的正态性进行了检验,进而利用Box-Jenkins方法对海浪水压场信号服从何种线性模型进行了辨识。结果表明,在100 s时间内,海浪水压场信号服从或近似服从正态分布,并可利用AR模型对其进行描述。 |

| Abstract: | Based on a large amount of the ocean wave hydrodynamic pressure field signal measured in South China Sea and Bohai Sea, the normality of the signal was tested with Epps-Pulley method. The result shows that the signal follows the normal distribution in a short time. Then, the linear model of the signal was identified by Box-Jenkins method, which proves that the signal can be described by the auto-regression model. |
