摘要:
Two different approaches have been used in the literature to discuss the nonlinearity of the scattered wave from a pulsating bubble in a liquid: The radial displacement approach and the volume displacement approach. These two treatments have been compared and it has been pointed out that there is no theoretical basis for the conclusion reached from the volume displacement approach that the second‐harmonic amplitude of the sound emission is zero at a specific frequency.
