| 摘 要： | 在应用能量线性叠加计算港内不规则波绕射系数时^1,2]，通过假设不同的计算点具有不同的方向谱，从而增加单源点法考虑地形变化的能力。其中各计算点的方向谱由逆波向线追踪方向确定。本文由此观点建立数学模型。并通过实例计算。来验证这个想法。

| Abstract: | By assuming that different points in a harbor have varied spectra, a singularity distribution method has been proposed which could take underwater topography difference into account in calculating diffraction coefficient of irregular wave in a harbor by linear superimposing diffraction coefficients of composing waves on energy weight, in which the spectrum at computing points is given by the back tracing method. From this viewpoint, a mathematical model was established, and then verified with an example. |
