本文对船舶在波浪中的非线性横摇运动研究的现状进行了小结，讨论了所存在的一些问题及其发展趋势。对横摇非线性问题的产生以及导致非线性的因素作了简述后，从大幅非线性横摇运动、横摇－垂荡耦合运动、横摇－纵摇耦合运动三方面，详细综述了国内外关于船舶在波浪中的非线性摇摆研究工作中采用的各类典型数学模型，以及主要成果和进展。最后讨论了船舶非线性动力学中几个有待深入研究的问题。

A summary of the recent research situation and the discussion on the recent problems and the tendency of development for nonlinear rolling of ships in waves are presented in this paper. Firstly, the causes and the factors leading to the nonlinear ship motion are stated briefly.Then the typical analytical models employed, the principle achievements at home and abroad and the prospects of the research works on nonlinear ship rolling are reviewed in detail in three aspects: large amplitude ship rolling; the coupling of rolling and heaving, and the coupling of rolling and pitching. Finally, the topics that should be studied and explored in depth in future researches on the nonlinear dynamics of ships in regular and random waves are suggested.
