本文用摄动方法导出了均匀水底上精确至二阶的二维随机波动解。依据此解并将二阶谱定义为三阶矩函数的Fourier变换,首次给出了精确至二阶的二维随机波面二阶谱的理论表达式并简略地考虑了它的各个组成部分的物理意义。
In this paper, the perturbation method is used to derive the exact second-order two-dimensional stochastic volatility solution on a uniform underwater. According to this solution and the definition of second-order spectrum as the Fourier transform of the third-order moment function, for the first time, the exact second-order two-dimensional stochastic two-dimensional spectrum of the theoretical expression and briefly consider its various components of the physical significance.
