[Model of an ecological system closed as regards gas metabolism and with a periodically working autotrophic component. I. Conditions for stability of the atmospheric system].
The paper describes a semi-closed ecological system consisting of a man and a photosynthetic autotrophic component. The conditions required to maintain the stability of the atmosphere in the system are described as applied to two alternating modes of the function of the autotrophic component. These conditions express equal quantities of oxygen and carbon dioxide consumed and produced by the components of the system during any time period the length of which is the duration of the cycle of the system. On this basis equations have been derived which help to identify the photosynthetic cultures that can be used as an autotrophic component in a closed man-sustaining life support system.
