First through a low velocity core, and then through a high velocity shell, where their speed is increased before they are transmitted into the surrounding seawater.

它们首先通过一个低速的核心，然后通过一个高速的外壳，在它们被输送进周围的海水之前，它们的速度提高了。

Velocity refers to the speed requirement for collecting, processing, and using the data.

速度表示收集、处理和使用数据的速度需求。

youdao

There is a very big difference in physics between speed and velocity.

物理中速率和速度的概念,是泾渭分明的。

youdao

This is the starting speed, that's the rate at which it is gaining velocity, and that's how long it's been gaining it.

这是起始时的速度,这是速度的增长速率,这是加速的时间

What it means is if you'd release a rock at that location one second before with a certain speed that we can calculate, it would've ended up here with precisely the position and velocity it had at the beginning of our experiment.

它的意义在于,若在该处以特定速度抛出一个物体,这个速度可通过计算得到,一秒之后,物体会运动至我们设定的起点,并且速度为我们设定的初速度

This involves pitching the machine's nose up to reduce its forward velocity and increase the speed of rotation of the blades (and thus the amount of lift they provide) to soften the landing.

ECONOMIST: Monitor

They start businesses and buy foreclosures and speed the velocity of money around the economy with a gush of pent-up desire to consume after years in the desert.

FORBES: There is also some possibility that the world won't end, you know
