稳静的

The stability criteria on the hydrostatics theories are used to estimate whether aship in the heavy seas capsize or not,this method ignores the time domaincharacteristics, frequency characteristics and the randomicity of ship motions. Thecapsizing accidents occur now and then although ships are designed according tostability criterion. So, it is also the important problem for human beings to investigatethe nonlinear characteristics of ship motions and evaluate the survival ability of ships.
