ethod of determination of wall maximum humification localization for analysis of protection against compound building wall excessive moistening // 2628530
FIELD: measuring equipment.SUBSTANCE: one measures the wall temperature, where the wall outside surface temperature is measured in the capacity of the wall temperature, the interior wall temperature and the temperature among the material layers that form the wall. One also measures the integral outside air temperature for the period with the negative average monthly temperature and the indoor temperature. After that, one draws the polygonal line of the temperature variation across the wall thickness. Afterwards, one compares the temperature value on the boundaries in each of the wall layers with the temperature in maximum humification localization for every wall material layer by virtue of the construction of a temperature curve diagram across the material layer thickness and the temperature graph in maximum humification localization across the material layer thickness. This graph is a horizontal line of a constant temperature across the wall thickness. And if the line of the temperature in maximum humification localization intercrosses the temperature variation across the wall thickness line, then one verifies that the maximum humification localization of the wall material layer passes against the wall through the crossing point of the above-mentioned lines. If there is no maximum humification localization in two neighbouring layers and, at the same time, the maximum humification line in wall material outer layer lies higher than temperature variation line in this layer, the line of the temperature in maximum humification localization in the inner layer lies below the temperature variation line in the inner layer, then one verifies that the wall maximum humification localization centres around the joint of the two layers of this wall. And if the maximum humification localization is not determined in accordance with the two above-stated versions, then one verifies that it is placed along the outer surface of the wall outer layer.EFFECT: simplification of the analysis of protection against excessive moistening.4 dwg

FIELD: radio engineering, communication.SUBSTANCE: radar location method with carrier frequency tuning from pulse to pulse consists in obtaining a signal of carrier frequency by direct heterodyning method of radio pulses of a fixed frequency up in frequency by the frequency value of the heterodyne signal and receiving the reflected signal by return heterodyning method by shifting it down in frequency, followed by filtering of the reflected signal at frequency of radio pulses of a fixed frequency by a frequency-selective device. Carrier frequency tuning is carried out by changing the frequency of the heterodyne signal, in case of direct heterodyning, the response of the frequency-selective device to the ultrashort pulse action is used as the fixed frequency radio pulses, and after return heterodyning, the filtering of the reflected signal is performed by the same frequency-selective device. Direct and return heterodyning are performed by the same device.EFFECT: ensuring the optimal reception of reflected signals during carrier frequency tuning of the emitted radio pulses from pulse to pulse without requiring long-term stability of the frequency parameters of the incoming devices and with a simpler practical implementation.2 cl, 4 dwg
