Abstract: FIELD: measuring equipment. 
     SUBSTANCE: invention relates to measurement equipment, in particular to measurements of electric resistances by electric bridges, and can be used, for example, in temperature measurements, including at calibration of resistance thermometers, thermistors and posistors, at temperature measurements with electric bridges. Essence of the disclosed technical solution lies in the fact that in the method of reducing temperature measurement error by an electric bridge, supplied from a voltage source, in the measuring branch of the bridge there installed is a constant resistor with high electric resistance, and the value of voltage of the power supply source of the bridge is selected from the condition of provision of permissible error of temperature measurement by the bridge due to heating of thermistor by flowing measuring current. Besides, in the proposed method to achieve the set goal: thermistor can be used as thermal resistor, resistance value of constant resistor in measuring branch of bridge is selected not less than 0.8 of value of resistance of thermistor at lower boundary of range of measured temperatures, and voltage value of power supply of bridge, providing permissible error of temperature measurement by bridge due to heating of thermistor by flowing measurement current, is set for lower boundary of range of measured temperatures; as a thermistor there can be used a resistance thermometer or a posistor, value of resistance of constant resistor in measuring branch of bridge is selected not less than 0.8 of value of resistance of resistance thermometer or posistor at upper boundary of range of measured temperatures, and voltage value of power supply of bridge, providing permissible error of temperature measurement by bridge due to heating of resistance thermistor or posistor with flowing measurement current, is set for upper boundary of range of measured temperatures; value of power supply voltage of bridge, providing permissible error of temperature measurement by bridge due to heating of thermistor, can be installed using expression 
     
       
     
     where R 4  is the value of the resistance of the corresponding thermistor in the measuring branch of the bridge at the corresponding boundary of the range of measured temperatures; R 3  is resistance value of constant resistor in measuring branch of bridge; ΔT is permissible error of temperature measurement by the bridge due to heating of thermistor by flowing measurement current; δ T  is coefficient of thermal dissipation of appropriate thermistor. 
     EFFECT: reduced error of temperature measurement by electric bridge due to heating (self-heating) of thermistor (resistance thermometer, thermistor, posistor) flowing measurement current.

Abstract: Изобретение относится к способам утилизации опавших листьев с деревьев и кустарников на территориях населенных пунктов. Размещают на земельном участке  в грунте емкость коробчатой конструкции. На помещенную сетчатую перегородку в емкости над ее дном осуществляют периодически плотную укладку послойно предварительно увлажненных раствором перегноя растительных отходов через прослойку почвы до ее полного заполнения. Обеспечивают полив водой содержимого емкости до момента созревания перегноя одного из очередных уложенных слоев на сетчатой перегородке. Удаление созревшего слоя с нее проводят путем его размыва водой, размещаемой в полости между сетчатой перегородкой и дном с отстойником на нем, при импульсном воздействии ею на него при ее барботировании с последующим осаждением взвешенных его частиц в отстойник в виде илоподобной массы на дне емкости и дальнейшей ее откачкой из него с помощью илонасоса. Устройство для получения перегноя из растительных отходов - опавших листьев, представляет собой пространственную тонкостенную конструкцию из полимерного материала с гидрофобной поверхностью в виде открытой емкости коробчатого типа. Емкость содержит дно с расположенным в нем желобообразным отстойником для сбора созревшего перегноя и сетчатую перегородку, установленную разъемно над ним, для укладки растительных отходов. Снабжена трубопроводом для подвода воды в полость, образованную между дном и сетчатой перегородкой, двумя воздухопроводами: одним для барботирования через его ниппелевые жиклеры воды в ней в зоне контакта с сетчатой перегородкой и другим - для сбрасывания избыточного воздуха в процессе барботирования из нее в атмосферу, а также трубопроводом для откачки илоподобного перегноя из отстойника. Техническим результатом является получение перегноя в замкнутом цикле из растительных отходов, компостируемых периодически слоями, с обеспечением возможности удаления созревшего слоя перегноя без вскрытия поверхностного слоя. 2 н.п. ф-лы, 1 ил.
