critical speed

基本解釋

And this is the critical speed, which has a 1-over-r relationship.
這是臨界速度，是1>r的關(guān)系。
Well, this critical speed for a small ball bearing would be some hundred meters per second.
小滾珠的臨界速度,也許是每秒幾百米。
Now you could say, "Well, what is the meaning of this critical speed here if they never reach that speed anyhow?"
現(xiàn)在，你可以問，如果不可能達(dá)到那個(gè),速度，那么臨界速度,在這里的意義是什么

For all retailers, efficiency is critical and speed of delivery is nearly as important as the cost of the goods sold.
