1) in-motion waterline
航行水线
2) run
[英][rʌn] [美][rʌn]
艉水线,航行,航程
3) waterline in the lightest seagoing condition
最轻载航行水线
4) flying waterline
水翼航行状态水线
5) non-streamline submerged body
非流线型水下航行体
1.
Taking a non-streamline submerged body as a model, its drags under the natural condition and artificial ventilated condition are numerically simulated using mixed homogeneous flow theory and realizable κ - ε turbulence model.
针对某水下非流线型航行体的试验模型,采用混合均质流理论、Realizableκ?ε湍流模型进行了自然状态和通气产生超空泡状态下阻力的数值模拟,通过对流线型航行体的数值模拟和经验公式的比较验证了采用方法的适用性,得到了自然和通气状态下非流线型水下航行体的阻力变化规律。
6) feasible routes
可行航线
1.
Firstly,all feasible routes are generated,solving the problem of "feasible routs with time and carrying capacity restriction";Secondly,recoumended routes are selected from the feasible routes,aiming to minimize the total transportation cost on the basis of satisfying each port′s demand.
以长江集装箱班轮运输系统为研究对象,采用两阶段分析方法:第一阶段,寻找可行航线,解决“寻找满足时间、运量约束的可行流问题;”第二阶段,航线优选,对第一阶段的“可行航线”进行优选,在保证各港口都被访问、满足其运量需求的基础上,实现整个班轮运输系统总成本最低,得到内河班轮运输航线的优化设置。
补充资料：流线型
前圆后尖，表面光滑，略像水滴的形状。具有这种形状的物体在流体中运动时所受阻力最小，所以汽车、火车、飞机机身、潜水艇等的外形常做成流线型。
