Maneuverability is one of the most important performances of navigation,which has a great influence on ships transport safety.

操纵性是船舶航行的重要性能之一，其对航运安全有非常大的影响。

With the fast development of the world trade and the technology of navigation, a vessel is becoming larger in size, higher in speed, more specialized in use and automatic in manoeuver; the seamen are much more multinational, and some sea areas are undergoing a heavier transportation pressure. All of these make the navigation environment worse and svessels manipulating ability lower, especially in those narrow channels.

但是，随着现代世界贸易和航海技术的飞速发展，船舶向大型化、高速化、专用化、自动化发展，船上配员向多国籍化发展，局部地区交通运输日益繁忙，尤其是在狭水道操纵安全，使得船舶航行环境变的恶劣和船舶运动性能也有所降低。

This is why old people are always the phenomenon as a "Maracaibo Beacon" for vessel traffic.

这就是为什么老人们总是将该现象当作"马拉开波灯塔"，用于船只航行。

According to Floquet theory and transition curves of Mathieu equation, two different modified strained parameter methods are compared on precision of periodic solutions.

中文摘要：为研究参数横摇对船舶运动和倾覆的影响，通过对船在规则波上随浪航行时，恢复力矩中出现的1个以正余弦规律变化的强参数激励项进行适当的变量置换，将船舶的横摇运动方程转换成标准形式的Mathieu方程。

In order to study the effects of parametrical rolling on the ship movement and tilts, in allusion to ship's navigating in regular following waves, the equation of ship rolling motion is transformed into normal Mathieu equation by proper variable replacement when strong parametrical excitation in restoring moment varied according to sine or cosine wave.
