Examples of the use of the approximate method in solution 
of nonstationary heat-conduction problems are given. The error of 
this method is evaluated by comparison with exact solutions; it turns 
out to be several orders of magnitude smaller than the error in finite
-difference methods. Recommendations on employment of the method are given 
on the basis of the numerical experiments conducted.
