摘要
文章运用权械能流的观点，计算了宇宙飞船途径行星时所摄取的能量，并给出使飞船获得最大加速的条件。此外，文中还指出，天体之间的机械能流可能是太阳系中天体碰撞的重要原因之一。
Applying the point of mechanical energy flow the paper has calculated the energy abtained by spaceship from the planet and given the condition making spaceship abtain the maximum velocity. Besides, the paper also points out the mechanical energy flow between celestial bodies is probably one of the important reasons why celestial bodies happen to collide in the solar system.
