第三宇宙

按照力学理论可以计算出第三宇宙速度V3＝16.7公里／秒。

In accordance with the mechanical theory of the universe can be calculated in the third speed V3 = 16.7 km / sec .

全方位第三宇宙速度矢径，构成一个半径为43.5km/s的球面为基础的蛋形曲面。

The radius vectors of third cosmic velocity in every directions form a curved surface as egg . Itis based on a ball surface which radius is 43.5Km/s .

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。

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 .
