摆脱重力的束缚,自由自在地飞翔,是很多人的梦想。这种感觉确实奇妙,参加过失重飞机训练的大多数人,都以赞美的语言描述他们这种独特的体验。但是,如果人类长期处于失重状态,身体就会发生一系列的适应性变化。如果没有相应的对抗措施,就会危害人体健康,当返回地球后,人体很难再次适应重力环境。 Get rid of the shackles of gravity, flying freely, is the dream of many people. It was a fantastic feeling that most people who participated in negligent aircraft training described their unique experience in a complimenting language. However, if humans are permanently in a state of weightlessness, the body undergoes a series of adaptive changes. If there is no corresponding countermeasures, it will endanger human health, when returned to Earth, the human body is difficult to adapt to the gravity environment again.
