mass velocity

基本解释

As an increase in mass velocity, critical heat flux increased but critical steam quality decreased.
随质量流速增加，临界热负荷增加，而临界干度下降；
If you ever want to move yourself to the center of mass, you will have to know what the center-of-mass velocity is.
你若想要移动,在重心体系中，你就必须知道,重心速度是多少。
On the basis of experiment of two-phase pressure drop, for air-water flow through horizontal tube, the effect of mass velocity on the two-phase pressure drop is analyzed.
在对空气-水在水平放置的圆管内流动时的两相压降实验的基础上，分析质量流速对两相压降的影响。

And this is just a Newtonian expression of momentum, the product of the mass of the electron times its instant velocity.
这只是牛顿学上关于动量的表达，用电子质量,乘以瞬时速度。

And in terms of equations that we use, it's sometimes easier to plug in the fact, since momentum is equal to mass times velocity.
在我们使用方程这方面，事实上有时是很容易代入的，因为动量等于质量乘以速度。

One is inertial mass, which is how much you hate your velocity to change, how hard you resist acceleration.
一个是惯性质量,它反映了物体速度改变的难易程度,即保持加速度的难易程度

Momentum is mass times velocity, but all electrons weigh the same, so measuring their velocity was enough.
