摘要: 定量讨论了自由降落升降机中实际液滴的形状。结果表明,在地球附近,液滴大小在1m数量级时呈现明显的非球形,并与静态海潮形成的海洋表面形状相似,提供了一种在普通航天飞机中观察引力场非均匀效应的方法;给出了一种制造空间弯曲测量仪的设想。

Abstract: The shape of a liquid globule in a flee-falling elevator is calculated. The result shows that the shape of the globule near the Earth obviously departs from sphericity when it is about two or three meters, and its shape is similar to the shape of the bulgy ocean water caused by static tides. The methocks to olaserve the non-even effect of gravitational fields and to make apparatuses that can measure the curvature of curved space are given.

Key words: tidal force, shape of a liquid globule, local inertial frame, principle of minimum potential energy
