      <abstract xml:lang="ru">
        <p>За последнее десятилетие ультразвук благодаря его особенным свой­ствам нашел широкое применение в ряде отраслей науки и техники. Ультразвуковые волны используются при испытании материалов (де­фектоскопия), обработке материалов, сигнализации, определении рас­стояний и направлений (звуколокация — эхолот), в медицине, пищевой промышленности и т. д. В настоящее время почти нет отрасли народ­ного хозяйства, где бы не применялись ультразвуковые волны.</p>

        <p>Over the past decade, ultrasound has found wide application in a number of branches of science and technology due to its special properties. Ultrasonic waves are used in testing of materials (defectoscopy), processing of materials, signaling, determination of distances and directions (sonicolocation - echo sounder), in medicine, food industry, etc. Currently, there is almost no branch of national economy, where ultrasonic waves would not be used.</p>
