velocity n. 1.迅速;快速。 2.速度,速率。 3.周转率。 at a velocity of 100 miles per hour 用每小时一百英里的速度。 dart off with the velocity of a bird 像鸟一样迅速飞跑过去。 drag-free velocity无阻力飞速,真空飞速。 escape velocity(克服地球引力的)第二宇宙速度,逃逸速度。 final velocity (发射物的)终速。 initial [muzzle] velocity(发射物的)初速[腔口速度]。 uniform [variable] velocity匀[变]速。
Generally optimum operating velocity range ( see note ) 一般优化的运行流速范围(参阅注释)。
Note : there is an intermediate operating velocity within this range at which the disc may become unstable 注释:存在着一种中间运行流速,在这个范围内阀瓣变得不稳定。
In this paper, the relation among highway alignment, vehicle operating velocity, vehicle fuel consumption and vehicle dynamics is discussed synthetically . to evaluate and optimize the design of highway alignment, a " high alignment-vehicle move and system dynamic response " model has been established . by using the computer program of the system, which is written with visual c + + 6.0, one could easily draw out the variation curves of vehicle operating velocity, vehicle fuel consumption and some certain vehicle dynamics index 公路线形设计以汽车行驶规律为出发点,本文尝试以汽车系统动力学的观点研究道路线形设计问题,针对目前设计中存在的一些问题,建立了“公路路线??汽车运行响应模型”,分为行驶速度、耗油量预测和动力学响应计算两大模块,主要是为了克服传统汽车理论在指导公路路线设计时过于简化汽车,只考虑计算行车速度的弊端,力图通过建立“路线方案??行驶车速??力学响应”相互之间的量化关系模型,为公路线形指标的选取和优化提供一定的参考价值。
