Burgers equation is a one-dimensional analogue of the Navier-Stokes equations describing the dynamics of ﬂuids and it possesses all of its mathematical properties. Besides the Burgers’ equation, one of the few nonlinear partial diﬀerential equations which has the exact solution, and it can be used as a test model to compare the properties of diﬀerent numerical methods. A ﬁrst scheme is purposed for the numerical solution of the heat equation. It has a sixth-order approximation in the space variable, and a third-order one in the time variable. A second scheme is used for ﬁnding a numerical solution for the Burgers’s equation using the relationship between the heat and Burgers’ equations. This scheme also has a sixth-order approximation in the space variable. The numerical results of test examples are found in good agreement with exact solutions and conﬁrm the approximation orders of the schemes proposed.</abstract><trans-abstract xml:lang="ru">Предложены две новые разностные схемы повышенной точности для численного решения начально-краевой задачи уравнения Бюргерса. Уравнение Бюргерса является одномерным аналогом уравнения Навье–Стокса, описывающего динамику жидкости, и обладает всеми его математическими свойствами. Кроме того, уравнение Бюргерса относится к числу немногих нелинейных уравнений в частных производных, для которых известно аналитическое решение, что позволяет использовать его в качестве тестовой модели для сравнения свойств различных численных методов. Первая схема, предназначенная для численного решения уравнения теплопроводности, имеет шестой порядок аппроксимации по пространственной переменной и третий порядок по временной переменной. Вторая схема используется для нахождения численного решения уравнения Бюргерса на основе связи между уравнением теплопроводности с уравнением Бюргерса. Данная схема также имеет шестой порядок аппроксимации по пространственной переменной. Полученные на тестовых примерах численные результаты хорошо согласуются с аналитическими решениями уравнения Бюргерса и подтверждают порядок аппроксимации предложенных схем.</trans-abstract><kwd-group xml:lang="en"><kwd>Burgers’ equation</kwd><kwd>higher-order accurate numerical solution</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>уравнение Бюргерса</kwd><kwd>повышенной точности численного решения</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Zhu C.-L., Wang R.-H.
