Extended manned space missions will require regenerative life support techniques. Past U.S. manned missions used nonregenerative expendables, except for a molecular sieve-based carbon dioxide removal system aboard Skylab. The resupply penalties associated with expendables becomes prohibitive as crew size and mission duration increase. The U.S. Space Station, scheduled to be operational in the 1990's, is based on a crew of four to sixteen and a resupply period of 90 days or greater. It will be the first major spacecraft to employ regenerable techniques for life support. The paper uses the requirements for the Space Station to address these techniques.
长期载人航天任务将需要再生式生命保障技术。过去美国的载人任务使用的是非再生式消耗品，除了天空实验室上基于分子筛的二氧化碳去除系统。随着乘员规模和任务持续时间的增加，与消耗品相关的补给代价变得过高。计划在20世纪90年代投入使用的美国空间站，乘员规模为4至16人，补给周期为90天或更长时间。它将是第一艘采用可再生技术进行生命保障的大型航天器。本文利用空间站的要求来探讨这些技术。
