title: [Temperature environment and the heat exchange of astronaut in the emergency landing areas].
abstract: OBJECTIVE
  To analyze the temperature environment of different emergency landing areas and discuss the heat exchange between astronaut and the temperature environment. In addition, countermeasures against the emergency temperature environment were discussed.
  
  
  METHODS
  Heat exchange equation between man and environment was built using the law of energy conservation, and factors that affect the heat balance of human body were discussed.
  
  
  RESULTS
  It was found that temperature, humidity, air pressure, velocity of wind and solar radiation are factors affecting the thermal balance of the astronaut.
  
  
  CONCLUSIONS
  It is important for an astronaut to act properly and use the living devices and the environment conditions correctly during the emergency landing.
