摘要

In this paper, we consider the problem of identifying the thermal parameters in the temperature equation form some measured data, Based on the results given in papers [1] and [2], the optimal necessary conditions of the problem are presented. According to the Gateaux gradient of the cost functional with respect to the parameters, a dconditional gradient algorithm is constructed. Then the uniform continuity of the Gateaux gradient and convergence for the algorithm is proved. Finally, the numerical implementation is given and the result profiles are shown in the figures.
