Scattering on these inhomogeneities is characterized by a number of features, which distinguishes it from molecular scattering. At the same time, the intensity of scattering on impurity particles is comparable to the intensity of molecular scattering in a pure substance at concentrations of the order of 10% by volume.
На чертеже изображено устройство, реализзаощее ггредпсЯаемый способ.The drawing shows the device, the implementation of the method.
Устройство содержит источник света пазер 1, нагреватель 2, в который помещена кювета 3 с исследуемой жидкостью, фотоумножитель 4, усилитель 5 с самописцем. Луч лазера проходит через кювету с жидкостью . Рассе нный свет наблюдаетс через боковую стенку кюветы под углом 9О°С к падающему лучу. Температуру жидкости измер ют с помощью т-ермопары. Исследуемую жидкость предварительно отфильтровывают. Дл повг идени точности измерени температуры нагрев жидкости должен производитьс досThe device contains a light source Pazer 1, a heater 2, in which is placed a cuvette 3 with the test liquid, a photomultiplier 4, an amplifier 5 with a recorder. The laser beam passes through a cuvette with liquid. The scattered light is observed through the side wall of the cell at an angle of 9 ° C to the incident beam. The temperature of the liquid is measured using a t-thermopair. The test liquid is pre-filtered. In order to measure the temperature, the liquid must be heated
