1·I mean, that's the whole point of escape velocity, right?

我的意思是，这是逃逸速度的全部意义所在，不是吗？

2·Simply stated, a gas molecule can evaporate from a planet if it reaches a speed known as the escape velocity.

简单地说，如果气体分子达到逃逸速度，它就能从一颗行星上“蒸发”。

3·So we are burning up an enormous amount of fuel at every launch just to get the rocket up to what's known as escape velocity.

所以每一次发射我们都要耗费大量的燃料来让火箭达到所谓的“逃逸速度”。

4·Escape velocity is simply the speed of an object that's shot out of a cannon the minimum initial speed so that the object could later escape Earth's gravity on its own.

逃逸速度就是一个物体的速度，比如说，从加农炮中射出的最小初始速度，这样这个物体以后就可以自己脱离地球的引力。

5·Pendulum return, loop-the-loop, escape velocity.

钟摆回摆；转圈圈；逃逸速度。

6·Well, the answer lies in evaluating the escape velocity.

答案，是因为，逃逸速度的计算。

7·And so this term is the same as this term for your escape velocity.

这一项和这一项，逃逸速度相等。

8·At the event horizon, the escape velocity is equal to the speed of light.

在活动视界里，逃逸速度等于光速。

9·The buildup of pressure would force gas outward at speeds far above escape velocity.

压力的增加，将迫使气体以远高于脱离速度的速率向外逃逸。

10·A spaceship that reaches escape velocity is moving fast enough to break free of a planet's gravity.

太空船之所以能飞出地球，是因为其飞行速度很快，足以挣脱地球的引力。
