We consider the stationary problem of heat distribution in the n-layer infinite plate with nonideal thermal contact between the layers due to the presence of interlayer concentrated heat sources. Solution of the problem is obtained in closed form only through its output. Application of the results illustrated by an example. Found that the presence of concentrated heat source ideal conditions violated thermal contact, resulting jump advent of heat flow. First posed and solved the problem of determining the stationary heat transfer in multilayer plate with a given temperature and heat flow on the border of any two adjacent layers, including one of the external surfaces. Problem solving obtained for an arbitrary number of layers in closed form, expressed solely through output. The results illustrated article on a specific numerical example. In the study of the processes of heat conduction in multilayer bodies traditionally defined boundary conditions, ie, conditions in the start and end points. It is assumed that such terms may be "out of reach" and proposed to set conditions in any other, generally speaking, internal points. It turns out that this solved the problem Two-point makes it possible to clearly find the distribution of temperature field in the entire multilayer structure. This ensures particularly theorem of existence and uniqueness. The method of construction of two-point problem to Cauchy, which can be used in real situations at a certain temperature, fire and heat flux density. A scheme for solving stationary problem of heat conduction for multilayered flat wall if non-ideal thermal contact between the layers, which leads to a system of differential equations with impulse action theory which developed only in recent years.
