In addition, we have assumed that the system is in thermodynamical equilibrium, vapour bubbles and metal particles are distributed homogeneously, the metal is incompressible (  = 0), the bubble and particle sizes and the distance between them is much smaller than sound wave length.</abstract><trans-abstract xml:lang="ru">Получено выражение для скорости распространения малых возмущений (скорости звука) в среде, состоящей из жидкости, пузырьков пара и частиц металла. При этом сделано предположение, что рассматриваемая система находится с состоянии термодинамического равновесия, пузырьки пара и частицы металла распределены в жидкости однородно, металл несжимаем (  = 0), размеры пузырьков и металлических частиц, а также расстояние между ними значительно меньше длины звуковой волны.</trans-abstract><kwd-group xml:lang="en"><kwd>speed of a sound</kwd><kwd>steam vials</kwd><kwd>pressure</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>скорость звука</kwd><kwd>пузырьки пара</kwd><kwd>давление</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Crespo A.
