本文导出了常水深重力波非线性频散关系的两个表达式，一个是振幅谱离散的波场，另一个是波数能谱连续的波场。给出了四重波和二维Pierson-Moskowitz谱的数值例子，并讨论了一个重要的可能应用。
Two expressions for the nonlinear dispersion relation for gravity waves on water of constant depth are derived, one for wave fields with discrete amplitude spectra, the other for wave fields with continuous wavenumber energy spectra. Numerical examples for wave quartets and for two-dimensional Pierson–Moskowitz spectra are given, and an important possible application is discussed.
