摘　　要：本文对于在二维不规则波上随浪航行的船的稳性提出了三种检验计算方法:横摇运动的直接数值求解检验、均方渐近稳定判别和拟规则波处理检验;并给出了相应的计算公式及数值计算实例。本文所得出的计算结果与有关的研究结论相比较是符合的。The evaluation of the stability for ships in two dimensional irregular following waves can be made with three wethods. The first one is the numerical computation with the rolling motion equation derived with Runge-Kutta method. The second one is to discriminate whether the rolling motion satisfires the condition of asymptotic mean square stability. The third one is to examine the stability by assuming that the raudom term of the restoring moment in the rolling motion equation caused by the irreqular waves is a periodie motion. The calculated results and conclusion obtained with present methods coincide well with the relevant research works of the other investigators.
