Abstract: Изобретение относится к строительству, в частности к реконструкции и восстановлению зданий, и может использоваться для оценки качества гидроизоляции строительных конструкций. Способ оценки качества гидроизоляции включает определение влагопоглощения материала строительной конструкции путем измерения относительной весовой влажности и ее сравнения с нормативным значением. Новым является то, что дополнительно определяют паропроницаемость путем измерения скорости диффузии водяного пара, при этом для сравнения используют значение паропроницаемости, которое устанавливают экспериментально путем получения зависимости скорости диффузии водяного пара от относительной весовой влажности для влажного и высыхающего до постоянной массы образца, а качество гидроизоляции считают удовлетворительным, если измеренное значение скорости диффузии водяного пара для данной относительной весовой влажности меньше значения, полученного по экспериментальной зависимости. Технический результат изобретения состоит в повышении надежности результатов оценки качества гидроизоляции строительной конструкции. 1 ил.

Abstract: Изобретение относится к твердотельным устройствам для преобразования тепловой энергии в электрическую или к устройствам, использующим электрическую энергию для охлаждения. Согласно изобретению поддерживается тепловое разделение между эмиттером и коллектором с помощью частичного поверхностного контакта с площадью поперечного сечения, уменьшающейся в направлении точки контакта. Частичные поверхностные контакты могут быть связаны с эмиттером, барьером или коллектором. Сохранение теплового разделения между эмиттером и коллектором обеспечивает перенос электронов через барьер и уменьшает перенос электронов за счет теплопроводности. Таким образом, кпд увеличивается благодаря сбору баллистических электронов и уменьшению количества электронов теплопроводности, которые не могут собираться. Принцип изобретения действует как для электронной, так и для дырочной проводимости. Также предложен способ изготовления твердотельного термоэлектронного преобразователя. Технический результат изобретения заключается в получении высокой плотности энергии и высокого кпд в температурных режимах, характерных для термоэлектрических устройств. 2 н. и 27 з.п. ф-лы, 22 ил.

Abstract: FIELD: optics. 
     SUBSTANCE: device has circular metallic plate, in which a periodic matrix of rectangular slits is cut. Plate is positioned in such a way, that a falling beam of millimeter-long waves falls at an angle of 45° relatively to plate surface. Polarization of falling beam is parallel to plate surface. When direction of plate is such, that electric field is perpendicular to slits (i.e. electric field is directed transversely to lesser dimension of slits), plate transfers almost 100% of falling power. If the plate rotates around its axis for 90° (while keeping angle between falling beam and plate equal to 45°) in such a way, that falling electric field is parallel to slits, then plate transfers 0% and reflects almost 100% of falling power at an angle of 90° relatively to falling beam. By changing rotation angle between 0° and 90° both reflected and passed power can be continuously varied between values 0% and 100% from falling power. Light divider has cooling device for taking heat, absorbed from magnetic waves, away from edge of metallic plate. 
     EFFECT: continuous variation of reflected and passed power.
