На примере рассмотрения полуограниченного пространства с граничным условием первого рода показано, что построенные решения, по существу, являются точными, поскольку погрешность для широкой области значений параметров составляет сотые – десятитысячные доли процента.</p></abstract><trans-abstract xml:lang="en"><p>Results of numerical analysis of accuracy and convergence of solutions on the basis of the integral method of boundary characteristics are presented. It is shown by the example of consideration of a semi-bounded space with the first-kind boundary conditions that the solutions constructed are exact in essence because their error for parameters changing within a wide range comprises hundredth–ten-thousandth fractions of a percent.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>уравнение теплопроводности</kwd><kwd>приближенный метод</kwd><kwd>интегральные тождества</kwd><kwd>фронт возмущения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heat conduction equation</kwd><kwd>approximate method</kwd><kwd>integral identities</kwd><kwd>front of a disturbance</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Кот, В.
