Этот класс разбивается на облака — классы пространств, лежащих на конечном расстоянии от данного. В работе доказывается, что каждое облако является собственным классом. Между облаками естественно определяется расстояние Громова – Хаусдорфа по аналогии с метрическими пространствами. В работе показано, что при некоторых ограничениях расстояние между облаком ограниченных метрических пространств и облаком с нетривиальной стационарной группой равно бесконечности. В частности, посчитано расстояние между облаком ограниченных метрических пространств и облаком, содержащим вещественную прямую.</p></abstract><trans-abstract xml:lang="en"><p>The paper studies the class of all metric spaces considered up to zero Gromov – Hausdorff distance between them. In this class, we examine clouds — classes of spaces situated at finite Gromov – Hausdorff distances from a reference space. The paper proves that all clouds areproper classes. The Gromov – Hausdorff distance is defined for clouds analogous to the case of metric spaces. The paper shows that under certain limitations the distance between the cloud of bounded metric spaces and a cloud with a nontrivial stabilizer is finite. In particular, the distance between the cloud of bounded metric spaces and the cloud containing the real line is calculated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метрические пространства</kwd><kwd>расстояние Громова – Хаусдорфа</kwd><kwd>облака</kwd><kwd>собственный класс.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>metric spaces</kwd><kwd>Gromov – Hausdorff distance</kwd><kwd>clouds</kwd><kwd>proper class.</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">Edwards D.
