periodic oscillation

This paper,by means of the determination and error analysis of the initial stability of the general ship on passage,explains the relationship between the rolling period and the initial metacentric height,and tries to find the method of raising the accuracy in determining the initial stability in order to guarantee ship s navigation safety.
