Проведены количественные оценки СВЧ электропроводности исследованных образцов угля по данным ЭСР рубина.

Quantitative evaluation of the microwave conductivity of the studied coal samples based on the ESR measurements of ruby are made. Results can be applied for monitoring of electrical parameters of coals in the microwave range.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>каменные угли</kwd><kwd>электронный спиновый резонанс</kwd><kwd>электропроводность в СВЧ диапазоне</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coals</kwd><kwd>electron spin resonance</kwd><kwd>microwave conductivity</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">Эттингер, И.Л.
