一、前言伴随着宇航科学的发展,失重现象越来越受到人们的重视。特别是1957年宇航的进展,失重行为的研究已成为科学和工程上的重要內容。“失重”、“零G”、“零重力”或“自由下落”有时作为同义语来应用。“失重”一词多少是一种“误称”,甚至在空间也仍然存在太阳或其它星球的重力吸引,真正的零重力场仅存在于地球和月球或其它天体之间的平衡点上。对于一个轨道宇航器来说,重力场不
I. Introduction With the development of aerospace science, weightlessness is gaining more and more attention. Especially in 1957 the progress of aerospace, weightless behavior research has become an important part of science and engineering. “Weightlessness”, “zero G”, “zero gravity” or “freefall” are sometimes used as synonyms. The word “weight loss” is a kind of “misnomer”, and even in space there is still the gravity attraction of the sun or other planets. The real zero-gravity field exists only at the balance point between the earth and the moon or other celestial bodies. For an orbiting spacecraft, the gravity field is not
