Под центробежным потенциалом понимается потенциал, возникающий за счет центробежной силы. Сочетание метода разложения по собственным функциям гамильтониана, порождающего функциональный интеграл, и метода последовательностей Штурма для вычисления собственных значений используется для приближенного вычисления функциональных интегралов. Это сочетание позволяет значительно уменьшить счетное время и объем используемой памяти компьютера по сравнению с другими известными методами.</p></abstract><trans-abstract xml:lang="en"><p>Approximate evaluation of functional integrals containing a centrifugal potential is considered. By a centrifugal potential is understood a potential arising from a centrifugal force. A combination of the method based on expanding into a series of the eigenfunctions of a Hamiltonian generating a functional integral and the Sturm sequence method for the eigenvalue problem is used for approximate evaluation of functional integrals. This combination allows one to significantly reduce a computation time and a used computer memory volume in comparison to other known methods.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>функциональные интегралы</kwd><kwd>центробежный потенциал</kwd><kwd>собственные функции гамильтониана</kwd><kwd>последовательность Штурма</kwd></kwd-group><kwd-group xml:lang="en"><kwd>functional integrals</kwd><kwd>centrifugal potential</kwd><kwd>eigenfunctions of Hamiltonian</kwd><kwd>Sturm sequences</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">Янович, Л.
