Study on the stabilityofship is divided into two aspects, initial stability and stability at large angles of inclination.
对稳性的研究主要分为两个方面，即是船舶的初稳性研究和大倾角稳性研究。

A lot of accident ofship capsizes indicate that stabilityofship is good in still water, but stabilityofship is bad in waves.
国内外大量的船舶倾覆事故，已经说明了一个事实，静水中稳性好的船舶在波浪中稳性未必好。
