摘　　要：近年海上事故调查结果表明很多海难事件都与畸形波袭击有关。随着我国经济进步,海上经济和军事活动越来越频繁,畸形波对上述海事活动具有严重威胁并可能造成重大人员和财产损失。现有的数值或经验海浪预报方法不能有效地预报这种灾害性海浪,亟需开发一种可靠的畸形波预报方法,这是海浪研究中面临的新课题。本文将对畸形波的实验和理论研究现状进行简要回顾,并介绍目前畸形波生成条件预报方法的研究进展。Results of marine disaster research show that many shipwrecks were closely related to the attacks of freak waves.With the development of our country,the marine activities of economic and military became frequently.Consequently,the possibility of ships and drilling platforms threaten and destroyed by these disastrous waves is increasing.However,the traditional numerical and empirical methods are not able to forecast these extreme sea states.So,a reliable method of forecasting these events is required to be developed,which is a tough task for sea wave research.The results of experimental and theoretical research are reviewed briefly in this paper.The methods of freak wave conditions forecasting are also presented.
