非线性Schrödinger （NLS）方程是一种流行的、相对简单的模型，被广泛用于描述非线性水波群的演化。它经常被用来形容海洋中极其陡峭（怪异或流氓）的波浪。本文在定量和定性对比实验的基础上，考察了NLS方程适用性的局限性，特别是模型对异常涌浪的相关性。
The nonlinear Schrödinger (NLS) equation is a popular and relatively simple model used extensively to describe the evolution of nonlinear water-wave groups. It is often applied in relation to the appearance of extremely steep (freak, or rogue) waves in the ocean. The limits of the applicability of the NLS equation, and in particular the relevance of the model to rogue waves, are examined here on the basis of quantitative and qualitative comparison with an experiment.
