speed of escape的意思|示意

Also, because the molecular motion of a gas depends on temperature, at the low temperatures of the Jovian planets even the lightest gases are unlikely to acquire the speed needed to escape.

此外，由于气体的分子运动依赖于温度，在木星行星的低温下，即使是最轻的气体也不可能获得逃逸所需的速度。

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。

Eleven point two kilometers per second, at which satellites can be freed from the gravitation of the earth, is called "escape speed".

卫星以11.2千米每秒的速度前进可以脱离地球引力，这被称为“逃逸速度”。
