研究课题的由来在航运史上,全世界每年都会发生客轮沉没、渡船倾覆等海难事件。判断失误、气象预报不准确、导航与驾驶装置失控等人为与技术因素往往会引发轮船触礁、撞冰山等事故,而恶劣气候下的狂风巨浪是造成海难事件中人员惨重伤亡的主要原因。在海洋上一般无风也三尺浪,在陆地上刮二、三级风时,人们的感觉只是微风拂脸撩发,而海洋上的波浪已有一、二米 The origin of research topics In the history of shipping, shipwrecks, ferry capsized and other shipwrecks occur every year in the world. Man-made and technical factors, such as misjudgment, inaccurate meteorological forecast, out-of-control navigation and driving devices, often lead to accidents such as the ship reaching the rocks and colliding with icebergs. The huge winds and waves in adverse weather conditions are the main causes of heavy casualties among shipwrecks. In the ocean, there is no wind but also three feet of waves. On the land, when the wind blows two or three winds, the feeling of people is just a gentle breeze, while the waves on the ocean have one or two meters
