基于停船视距和船舶领域理论,根据动力学原理,推导出船舶制动减速过程表达式,在此基础上采用变量分离方法对制动距离进行积分求解,给出了船舶领域新的计算公式,并就其影响因素和具体应用进行了探讨。研究表明:船舶领域是关于船舶速度的增函数;对于进江海轮,航行速度通常限制在5~7 m/s,其船舶领域计算值为3~5倍船长;在开阔海域航行的海轮,船速可达20~25 kn,船舶领域计算值为6~8倍船长。

Based on stopping visual range, ship domain and principle of dynamics, we deduced an expression of ship braking deceleration process. Then by using separation of variables to integrate braking distance, we given a new calculation method of ship domain and discussed its influence factor and specific application. The research shows that the ship domain is an increasing function of ship speed. To seagoing vessels, the sailing speed in the Yangtze River is 5-7 m/s under speed limits and the ship domain is 3-5 times the skipper. The speed of seagoing vessel in the open sea area may be up to 20-25 knots and the ship do-main is 6-8 times the skipper.
