escape velocity 释义 逃逸速度:一个运动物体(如火箭)必须具有的最小速度,才能逃离天体(如地球)的引力场并向外进入太空。 例句 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”。
