摘　　要：本文根据劳斯判据分析了小水线面双体船（SWATH）静水纵向运动方程的稳定性，给出了适合于工程应用的纵向运动稳定性简化判据和临界巡航速度的计算方法。通过对三艘SWATH的实例计算，讨论了船形以及鳍的尺度、纵向位置和组合形式的变化对纵向运动稳定性的影响，提出了一种较完善的提高SWATH纵向运动稳定性的途径。The stability of longitudinal motion equation of SWATH ships in still-water is analysed in this paper according to the Routh criterion. A simplified method to determine longitudinal motion stability and to calculate critical cruising speed for engineering purpose is given. The effect of hull form and fins on longitudinal motion stability of SWATH ships is discussed. An available measure for improving the longitudinal motion stability of SWATH ships is also put forward.
