Damage stability curves of a series of damaged one - compartment respectively and combinations of damaged multi - compartments are needed in probabilistic method . systems of equation of floatation and stability may be divergent when damaged multi - compartments are calculated that may lead to programs stop . the reason is studied and that makes the programs can distinguish this case and eventurelly the probabilistic calculation of arbitrary damaged multi - compartments is carried out 在概率方法中，需要计算一系列的破舱组合下船舶的稳性曲线，由一舱破损、相邻两舱破损到相邻三舱破损再到相邻四舱破损等，由于这种破舱组合是由程序来实现的，多舱组合破损时计算过程中浮态与稳性的计算可能异常而导致程序中断。
