      <abstract xml:lang="ru">
        <p>Одним из важнейших аэрогидродинамических показателей любой флотационной машины является аэрация. С понятием аэрации отождеств­ляют количественные соотношения воздушной и жидкой фаз, а также ка­чественные характеристики крупности воздушных пузырьков и их распре­деления по объему камеры. Количественная сторона процесса аэрации может быть выражена через степень аэрации и плотность флотационной системы. ...</p>

        <p>One of the most important aerohydrodynamic indicators of any flotation machine is aeration. With the concept of aeration identify quantitative ratios of air and liquid phases, as well as qualitative characteristics of the size of air bubbles and their distribution over the volume of the chamber. The quantitative side of the aeration process can be expressed through the degree of aeration and the density of the flotation system. ...</p>
