Consideration has been given to the problem of uniform 
unsteady lateral heating of two bounded cylinders having dissimilar 
thermophysical characteristics and being in ideal thermal contact. 
The exact analytical solution for determination of a three-dimensional 
temperature field in real space has been found with the use of the 
integral-transformation method. The distinctive features of the solution 
obtained have been investigated and examples of specific calculations 
have been given.
