摘要
本文计算出从地球上发射物体使其能飞出太阳系所需的最小速度,即第三宇宙速度,为13.8km/s,与一些传统教科书中给出的16.7km/s有较大的差异.文中对产生差异的原因进行了分析.
In this paper, the third cosmic velocity i.e., the smallest velocity needed for launching an object from the earth into the space out of the solar system, is found to be 13.8km/s, quite different from 16.7km/s given in some traditional text books. Discussion is presented on the matters leading to the difference.
