THEME: "Identification of non-stationary fields of temperatures taking to account the final speed of heat spread" The full version in Russian only Due to intensive development of new techniques the questions of non-stationary heat exchange become more and more important in science works. Problem of studying of laws of non-stationary temperature fields spread in the bodies of a different geometrical form is connected with the solving of parabolic differential equalisations of heat conductivity with the various regional boundary conditions. This problem will be much more difficult if the final speed of heat spread is considered. On the basis of the phenomenological theory of thermodynamics of non-reversed processes are more complicated dependence between the thermal flux and temperature gradient was got and the hyperbolical equalisation of heat conductivity which takes into account the final speed of energy spread was constructed. |

However it holds true just for the non-equilibrium processes of moderate intensity. In my dissertation for master's degree the hyperbolical formula of equalisation of heat conductivity was got, which is based on simple physical essence and takes into account the final speed of heat spread without introductions of notion "relaxation time". The algorithm for solving the hyperbolical equalisation of heat conductivity is based on its approximation on the seven-point template. It allows to investigate the processes of non-stationary heat conductivity for the bodies of any geometrical form and boundary conditions. The adequacy to the analysed processes is confirmed by its comparison with the solution of row of model tasks, got on the basis of approximation methods ( "methods of thermal layer ").
