“奋斗者”号全海深载人潜水器使用氧烛作为应急情况下的供氧手段，期间3名乘员在载人舱内生存。氧烛是一种化学产氧手段，受工作原理所限，其产氧过程中有可能会产生微量CO，人体自身新陈代谢时亦会有CO排出。一氧化碳是一种毒性很强的有害气体，出于安全性考虑，有必要对氧烛供氧条件下载人密闭空间内一氧化碳浓度进行评估，确认其是否处于安全范围。为此，“奋斗者”号进行了一系列试验，对氧烛供氧条件下载人密闭空间内的一氧化碳浓度进行测量。本文对这些试验进行介绍，对试验的结果进行分析并给出结论。
The chemical oxygen generator is used as one of the means of oxygen supply in emergency situations of Fen dou zhe full ocean deep manned submersible, during which three crew members survive in the manned cabin. The chemical oxygen generator is a chemical means of oxygen production, limited by the working principle, the oxygen production process may produce trace carbon monoxide. Carbon monoxide is produced when the body is metabolized. Carbon monoxide is a highly toxic gas. For safety reasons, it is necessary to evaluate the concentration of carbon monoxide in a manned confined space when chemical oxygen generator is used for oxygen supply to confirm whether it is within a safe range. Therefore, "fendouzhe" has carried out a series of tests to measure the concentration of carbon monoxide in the confined space when the chemical oxygen generator is working. This paper introduces these tests, analyzes the test results and gives a conclusion.
