【 摘 要 】

Acoustic single bubbles in aqueous solutions of sodium dodecyl sulfate (SDS) have been studied. In dilute SDS solutions, the trapped bubbles are found to be stabilized and sustainable up to higher driving acoustic amplitude. Stroboscopic images of the bubble are consistent with theory, indicating dancing motion and intensive near-resonance oscillations of the bubble. A trace analysis of the bubble fluctuations reveals an oscillatory behavior of 'inverted pendulum' around the pressure antinode.
