Description: The approach to biological object internal temperature field analytical calculation is offered. It allows to recover depth temperature distribution on the basis of heat conductivity equation decision with measured temperature inwardly and on-thespot. With the use of Mathcad applied package some situations are modeled for the scope values of biological object two-layer model heat conductivity coefficients. They also are differed by ratio of the heat transfer coefficients and heat allocation sources volume power.
