Проведено обоснование метода и показана возможность его практического применения при оценке удельной поверхности пористых тел, содержащих микропоры. Показана ограниченность методов БЭТ для определения удельной поверхности микро- и микромезопористых материалов.Подчеркнута применимость метода БЭТ для исследований адсорбционных процессов в интервале относительных давлений адсорбатов 0,05–0,35.</p></abstract><trans-abstract xml:lang="en"><p>Essentially new method of definition of specific surface of micropores of micromesoporous adsorbents based on determination of side surface of a pore which is blocked by adsorbate molecules placed in her cross-section is proposed. Justification of the method is carried out and an opportunity of its practical application at estimation of a specific surface of the porous bodies containing micropores is shown. Limitation of the BET methods for definition of a specific surface of microporous and micromesoporous materials is shown. It is emphasized, that applicability of the BET method for analysis of adsorption processes is restricted by the relative adsorbates pressure of 0.05–0.35.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микропоры</kwd><kwd>поперечное сечение микропоры</kwd><kwd>БЭТ</kwd><kwd>мономолекулярный слой</kwd><kwd>микро- и микромезопористые материалы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>micropores</kwd><kwd>cross-section of micropore</kwd><kwd>BET</kwd><kwd>monomolecular layer</kwd><kwd>microporous and micromesoporous materials</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">Комаров, В.
