摘　　要：通过对船舶载重线勘划适用的比重计和商业计重使用的水尺检验员比重计的工作原理进行比较,阐述了引起船舶超载的一个重要原因--计量海水密度时使用不同比重计而产生超载.对于一般船舶这种差别可以忽略,而对于超长的超大型船舶则会引起多达3～4 cm吃水的误差.一个值得思考的问题就是对载重线公约和其他国际公约要从原理上去学习理解.By comparing principle of Ioadline hydrometer to surveyor hydrometer＇s, this paper tells us that capesize ship＇s overload is oftenly produced by using different type of seawater density measurement means. It could be disregarded for ordinary size ship, but it will generate up to 3-4cm difference of ship＇s draft by using different type of hydrometers- One conclusion is generated, that we must study and master the princles of loaclline convention and other international convertion carefully.
