1.速度,速率
2.周转率
3.迅速;快速
1.the speed that something moves at in one direction
1.If that were true for galaxies, the most distant visible objects in the sky would be receding at velocities just shy of the speed of light.
如果这对于星系也是正确的，那麽天空中可见的最遥远物体，就会是那些远离速度仅仅略小于光速的天体。
2.The extreme youth of at least one of these stars is indicated by the presence of a stream of gas moving at high velocities.
其中至少有一个非常年轻的恒星因高速运动的气体流而被暴露出来。
3.The suspended sediment of natural streams is usually made up of grains with a broad spectrum of sizes and fall velocities.
天然河流的悬沙，通常系由各种大小尺寸和沉速的粒子组成。
4.Despite these lower velocities, there appeared to be evidence for the operation of impact-abrasion phenomena in such situations.
尽管有这些速度低，出现了以证据为操作冲击磨损现象，在这种形势。这些证据分为若干领域，下面讨论。
5.All this comes out of Doppler shift measurements: the velocities, the radii, the periods and even the masses of these objects.
顿移测量法得到，速度，半径：，周期，以及，这些物体的质量，如果作为观察者。
6.We can measure the speeds of these galaxies, their orbital velocities, and figure out how much mass is in this cluster.
我们可以测量这些星系的速率，它们的轨道速度，并算出星系团中有多少质量。
7.Changes in sensory conduction velocities across the wrist appear to be the most sensitive electrophysiologic indicators of the condition.
变化的感觉传导速度在手腕似乎是最敏感的电生理指标的状况。
8.If widespread, such large space velocities could make a distribution typical of young stars mimic that of old stars.
如果广泛存在，这样大的空间速度，就可能使年青星的典型分布与老星分布相似。
9.From the experiment results and the normalization results, the surface recombination velocities of silicon pn junction were obtained.
通过测量结果和计算结果的归一化比较，获得了其表面复合速率。
10.As a whole, the groups with BRGs tended to have more galaxies which were more luminous, and had a greater variety of velocities.
总的来说，含有BRG的星系群倾向于含有更多的明亮星系，在周转速度上的差异也更大。
