化学氧在封闭空间生命保障系统中的应用试验

 为了研究化学氧在封闭空间生命保障系统中的应用，本文选择了超氧化钾进行实验。研究内容包括封闭空间内的温度、湿度和二氧化碳浓度对超氧化钾反应的影响以及超氧化钾在真人存在下的封闭空间内的反应状况。首先利用小型封闭空间模拟装置进行试验，实验结果表明湿度越大，越有利于超氧化钾反应；温度越高，越有利于超氧化钾反应；二氧化碳浓度越大，越有利于超氧化钾反应。然后进行了2人24小时和8人120小时的封闭空间试验，通过真人试验证明了超氧化钾在封闭空间内制氧是一种可行的制氧方式。

The application test of chemical oxygen in an enclosed space life support system

In order to study the chemical oxygen in the life support system of an enclosed space，this article we choose KO2 for studying. The research includes how the temperature, humidity and carbon dioxide influence the reaction of KO2 as well as the reaction of KO2 in the enclosed space condition with people. First, we use a small enclosed space simulation for testing, the experimental results show that the higher the humidity is, the more conducive to the reaction of potassium superoxide, the higher the temperature is, the more conducive to the reaction of potassium superoxide; the higher the carbon dioxide concentration is, the more conducive to the reaction of potassium superoxide. Then we make the experiment with 2 people in 24 hours and with 8 people in 120 hours in the closed space, it is proved that KO2 is an available method for producing oxygen in an enclosed space.
