摘　　要：论述了船舶在整个横倾过程中不发生纵倾，浮心只在船体剖面内作二维移动时的 稳性。建立了波浪稳性力臂的表达式和浮态方程式．并对一艘灯光兼围网渔轮在随浪 波峰上的稳性进行了计算，计算结果是满意的。还讨论了船舶在随浪中自由纵倾的情 况；提出了纵倾浮态方程式和流体动压力修正，从而给计算船舶在随浪中的稳性提供 了一种方法。The stability of ship without trimming in all process of the transverse inclination is discussed, i. e. the centre of buoyancy is shifted only in a body plane. The formula for the lever of stability on waves and the equation of floating condition are constructed.The stability of a fishing boat on wave crest of following sea is computed. The computation result is reasonable. The conditions of ship with free trimming in following sea are discussed,and the equation of floating condition with trimming and the modification of fluid's dynamics are presented. Therefore the method to compute ship stability is proposed.
