在人类进入太空之前,失重问题曾令人十分担忧。没有重力,人的身体——心理会发生什么问题呢?乘电梯下落时的感觉如果持续几天甚至几个星期,会不会引起终生恐慌症? 好在问题并没有那么严重。宇航员们发现,失重虽然有些令人讨厌,但是可以适应的。患有空间运动病(如晕车、晕船等)的人,只需忍受轻微恶心的折磨。2/3的宇航员在第一次太空飞行时都有典型的运动病症状。 The problem of weightlessness has caused great concern before humans can enter space. Without gravity, what happens to the human body-mind? What do you feel when you take the elevator down for several days or even weeks? Will it cause a lifetime panic disorder? Fortunately, the problem is not that serious. Astronauts have found that weight loss, while somewhat annoying, can be accommodated. People with space motion sickness (motion sickness, seasickness, etc.) suffer from minor nausea. Two-thirds of astronauts have typical symptoms of motion sickness on their first space flight.
