[A method of evaluation of the adaptation process].

The problem of adaptation cannot be reasonable well studied without due regard of the principle of reflection. The relationship between adaptation and reflection is realized in, for instance, the adequacy of body reactions to environmental impacts. The paper approaches this problem in the light of thermodynamics. A simple method for accounting the process of adaptation to continuous exposure in specially designed sealed chamber on the pattern of shift work of operators is proposed. The investigation embraced 29 divers aged 20-25 who stayed in shifts for long periods in a chamber with artificially and synthetically sustained air parameters. The investigation demonstrated the effectiveness of the description of adaptation process through probabilistic models with a high level of generalization, and the possibility to predict operator's functioning at various phases of his work cycle.
