THE THEORETICAL BASES OF GAS CHANGE PARAM ETERS CALCULATIONS REALIZEDTHROUGH THE SYSTEM CIRCULATION OF THE GAS CARRIER BETWEEN WATER LIVING ORGANISMS IN A GERMETICALLY CLOSED VESSEL AND EXTERNAL ENVIRONMENT

Theoretical bases of the experimental method providing life activity o f water organisms in critical conditions have been developed. The orga nisms were supposed to be kept in a germeticaly closed vessel equipped with a gas carrier circulation, system. The organisms located in the vessel absorb some gases (for example O-2), and release others (for ex ample CO2, NH3, and etc.). In the circulation system the gas carrier i s saturated with oxygen, then it transfers the gas to the vessel and g ives it back into water. After that the gas carrier captures the metab olic gas products a life activity (CO2, NH3,...) from the vessel water and releases them in to the circulation system. The main mathematical law describing the required gas exchange process between the water of a germeticaly closed vessel and environment by means of the gas carri er is found. The mathematical expressions describing the dependences o f the concentration changes of the gases in vessel water on: - speed o f object gas absorption, - circulation speed of carrier, main physical constants of the gas dissolution process in the carrier and in water, - quantity of water in vessel, and on the efficiency of the oxygenati on and regeneration systems are analyzed.
