| 摘 要： | "航天员从地球低轨道上裸眼能否看到长城",这个问题引起广泛关注和争论。争论焦点涉及如何正确认识人眼视觉原理等问题。应用国内外出版物中公开介绍的目视方面的军事科技理论和计算公式,从人眼视觉阈、视角阈等基本概念入手,通过理论分析、计算与实验,最终验证了"航天员从地球低轨道上裸眼看到过长城"的事实。

| Abstract: | The issue whether astronauts can see the Great Wall with naked eyes from the lower orbit round the Earth has been in dispute and focus. The major arguments include how human eyes work in principle. In this paper, military technical theories about human eyes and related formulas published both at home and abroad are analyzed and applied. Based on the concepts of visibility threshold and visibility angle, through theoretical analysis, calculations and experiments, the fact of "astronauts can see the Great Wall with naked eyes from the lower orbit round the Earth" is finally established. |
