Она посвящена новому универсальному методу сглаживания, первоначально предназначенному для анализа геофизических временных рядов. Гравитационные сглаживания легли в основу изучения ускорения векового хода главного магнитного поля Земли на основе данных обсерваторий сети ИНТЕРМАГНЕТ. Но свойства оператора сглаживание до сих пор не были изучены. Данная статья – первый шаг в этом направлении.</p></abstract><trans-abstract xml:lang="en"><p>This article continues the cycle of works by authors on the development of mathematical aspects methods of artificial intelligence for the processing of observations conducted under the guidance of academician A.D. Gvishiani, which was began in 2000. It is devoted to a new universal method of smoothing, originally intended for the analysis of geophysical time series. Gravitational smoothing formed the basis for studying the acceleration of the secular course of the Earth’s main magnetic field with using of the observational data of the INTERMAGNET network. But the properties of the smoothing operator have not been studied so far. This aticle is first step to this goal.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гравитационное сглаживание</kwd><kwd>невязка гравитационной гладкости</kwd><kwd>меры близости</kwd><kwd>оператор сглаживания</kwd><kwd>собственные значения</kwd><kwd>спектральные свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gravitation smoothing</kwd><kwd>discrepancy of gravitational smoothing</kwd><kwd>proximity measures</kwd><kwd>smoothing operator</kwd><kwd>eigenvalues</kwd><kwd>spectral properties</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Российский научный фонд, проект 16-17-00121</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Самарский А.А.
