Для учета фазовых и химических превращений в одном из слоев стенки применяется δ-функция Дирака. При постановке задачи использованы нелинейные уравнения теплопереноса с учетом зависимости теплофизических характеристик от температуры. Решение реализовано мето­дами численного эксперимента и компьютерного моделирования.</p></abstract><trans-abstract xml:lang="en"><p>A mathematical model for non-stationary heat conduction of multi-layer bodies has been developed. Dirac’s δ-function is used to take into account phase and chemical transformations in one of the wall layers. While formulating a problem non-linear heat conduction equations have been used with due account of dependence of thermal and physical characteristics on temperature. Solution of the problem is realized with the help of methods of a numerical experiment and computer modeling.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Есьман, Р.
