Abstract：
A CELSS (Controlled Ecological Life Support System) is a device that utilizes photosynthetic organisms and light energy to regenerate waste materials into oxygen and food for a crew in space. The results of theoretical and practical studies conducted by investigators within the CELSS program suggest that a bioregenerative life support system can be a useful and effective method of regenerating consumable materials for crew sustenance. Experimental data suggests that the operation of a CELSS in space will be practical if plants can be made to behave predictably in the space environment. Much of the work currently conducted within the CELSS program centers on the biological components of the CELSS system. The work is particularly directed at ways of achieving high efficiency and long term stability of all components of the system. Included are explorations of the conversion of non-edible cellulose to edible materials, nitrogen fixation by biological and chemical methods, and methods of waste processing. It is the intent of the presentation to provide a description of the extent to which a bioregenerative life support system can meet the constraints of the space environment, and to assess the degree to which system efficiency and stability can be increased during the next decade.
摘要：
CELSS（受控生态生命支持系统）是一种利用光合生物和光能将废物再生为氧气和食物的装置，供太空人员使用。CELSS计划中的研究人员进行的理论和实践研究结果表明，生物再生生命支持系统可以是再生消耗材料以维持船员生计的有用且有效的方法。实验数据表明，如果可以使植物在太空环境中具有可预测的行为，则CELSS在太空中的操作将是实用的。目前在CELSS计划中进行的许多工作都集中在CELSS系统的生物组件上。该工作特别针对实现系统的所有部件的高效率和长期稳定性的方法。包括将非食用纤维素转化为可食用材料的探索，生物和化学方法固氮，和废物处理方法。演讲的目的是描述生物再生生命支持系统在多大程度上可以满足空间环境的限制，并评估系统效率和稳定性在未来十年内可以提高的程度。
