[Characteristics of the heat exchange of the body with the environment (research on a heat physics model)].

In the heat physics model of the rabbit body (with no regulation), thermal discrete stimuli (20-min duration) induced a change of the model body temperature by +/- 0.5 degree C of an established level. Returning of ambient temperature to initial value did not return the model body temperature to initial level for a long time (6-8 hrs). A thermal discrete action equal in value but opposite in direction was necessary for restoration of initial level of the model body temperature.
