velocity n. 1.迅速;快速。 2.速度,速率。 3.周轉(zhuǎn)率。 at a velocity of 100 miles per hour 用每小時(shí)一百英里的速度。 dart off with the velocity of a bird 像鳥一樣迅速飛跑過去。 drag-free velocity無阻力飛速,真空飛速。 escape velocity(克服地球引力的)第二宇宙速度,逃逸速度。 final velocity (發(fā)射物的)終速。 initial [muzzle] velocity(發(fā)射物的)初速[腔口速度]。 uniform [variable] velocity勻[變]速。
Generally optimum operating velocity range ( see note ) 一般優(yōu)化的運(yùn)行流速范圍(參閱注釋)。
Note : there is an intermediate operating velocity within this range at which the disc may become unstable 注釋:存在著一種中間運(yùn)行流速,在這個(gè)范圍內(nèi)閥瓣變得不穩(wěn)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 公路線形設(shè)計(jì)以汽車行駛規(guī)律為出發(fā)點(diǎn),本文嘗試以汽車系統(tǒng)動力學(xué)的觀點(diǎn)研究道路線形設(shè)計(jì)問題,針對目前設(shè)計(jì)中存在的一些問題,建立了“公路路線??汽車運(yùn)行響應(yīng)模型”,分為行駛速度、耗油量預(yù)測和動力學(xué)響應(yīng)計(jì)算兩大模塊,主要是為了克服傳統(tǒng)汽車?yán)碚撛谥笇?dǎo)公路路線設(shè)計(jì)時(shí)過于簡化汽車,只考慮計(jì)算行車速度的弊端,力圖通過建立“路線方案??行駛車速??力學(xué)響應(yīng)”相互之間的量化關(guān)系模型,為公路線形指標(biāo)的選取和優(yōu)化提供一定的參考價(jià)值。
