航天服是保障航天员的生命活动和工作能力的个人密封装备,它可防护空间的真空、高低温、太阳辐射和微流星等环境因素对人体的危害.在真空环境中,人体血液中含有的氮气会变成气体,使体积膨胀.如果人不穿加压气密的航天服,就会因体内外的压差悬殊而发生生命危险.航天服是在飞行员密闭服的基础上发展起来的多功能服装.早期的航天服只能供航天员在飞船舱内使用,后
Spacesuit is a personal seal that protects the life activities and working abilities of astronauts. It protects the human body from environmental factors such as vacuum, high and low temperature, solar radiation and micro-meteor. In a vacuum environment, the human body contains Nitrogen will turn into gas, so that the volume expansion.If you do not wear a pressurized airtight spacesuit, it will be due to the great pressure difference between the body and the outside and life-threatening. Space suit is developed based on pilots in the closed clothes and more Functional clothing. Early space suits can only be used by astronauts in spacecraft cabins
