Methods and results obtained in ultrasonic research
Methods and results obtained in ultrasonic research; most important generators are electrically excited piezoelectric crystals and magnetostriction generators; for study of extremely high frequencies, optical methods, especially those of light reflections, are recommended; it is now possible to make ultrasonic waves visible; applications. (French abstract) (See also VDI Zeit v 80 n 20 May 16 1936 p 581-6)
