Это описание основано на обобщенном уравнении Фоккера-Планка Колмогорова. Основное положение таково: детерминированные уравнения и их решения – есть средние значения стохастической модели  задачи  Стефана.  Рассмотрена  проблема  деформирования  фрон та  фазового перехода. Исследование производится с помощью введенного положения устойчивости по дисперсии решений для средних значений. Результатом исследования является тот вывод, что  влияние марковского коэффициента диффузии приводит к  значительному искажению первоначально плоского фронта границы раздела фаз.</p></abstract><trans-abstract xml:lang="en"><p>The presented work offers the stochastic description of the  Stephan’s problem in hyperbolic representation equation. This description is based on the generalized Fоккеr-Plank-Kolmogorov equation. The basic thesis of this work is that the determined equalizations and their decisions are the average values of stochastic Stephan’s task model. This work considers the problem of phase transition front deformation. The research is performed using the entered position of stability on dispersion of decisions for average values. The conclusion of the study is that Markov’s diffusion coefficient leads to a significant distortion of the originall y flat front of the phase boundary. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>Задача Стефана</kwd><kwd>гиперболическое уравнение теплопроводности</kwd><kwd>обобщенное уравнение Фоккера-Планка-Колмогорова</kwd><kwd>устойчивость решений дифференциальных уравнений</kwd><kwd>деформация фронта фазового перехода</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Stefan problem</kwd><kwd>hyperbolic equation of heat conduction</kwd><kwd>generalized equation of the Fokker-Planck-Kolmogorov</kwd><kwd>stability of solutions of differential equations</kwd><kwd>deformation of the phase transition front</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">Stefan J.
