The random waves, non-linear damp and ship non-linear restore moment are taken into consideration and the ship rolling non-lineardifferentialequation is established.

In This paper, linear steady analysis is Made from the solution of non-lineardifferentialequation and Luther, the situation of steady state or non-steady state is discussed.
本文从非线性微分方程的解过渡到线性稳定分析，从而讨论出稳定态与非稳定态的情况。
