n.名词
C 速度speed
Noun:
distance travelled per unit time
n.名词
velocity, speedspeed指运动的速度,既可指快速,也可指慢速; velocity表示沿一定路线运动的速度,通常指直线、弧线或圆周运动的速度,这个词可与speed通用,但多用于科学技术方面。例如: The velocity of sound falls far short of the speed of light.音速远不及光速快。speed，rate，velocity，pace这些名词均含“速度、速率”之意。 speed普通用词，指单位时间内行进的固定速度或速率，也指可能达到的最高速度。 rate作“速度”讲时，与speed同义，可换用。作速率解时，指相对增长的速度，也指两种相比较而得出的标准速度。 velocity技术用词，指物体沿着一定方向运动时的速率。 pace普通用词，指步行的速度，常引申指活动的进度或生产率。 final velocity最终速度…normal velocity正常速度absolute velocity绝对速度velocity pressure速度压力critical velocity临界速度average velocity平均速度muzzle velocity初速度sedimentation velocity沉积速度flow velocity流速velocity profile速度剖面,速度分布图…velocity head速位差,速度头,动压…relative velocity相对速度peripheral velocity圆周速度velocity gradient速度梯度velocity potential速度势apparent velocity视速度,表观速度…terminal velocity终速,自由沉降速度…velocity ratio传动比,潮流振幅比…particle velocity质点速度velocity modulation蒂,速调系统,速度灯…
