文摘A single bubble trapped at an antinode of an acoustic standing wave field in water can emit 50ps-140ps light pulses, called “single bubble sonoluminescence” (SBSL). It arouses much interest in physical acoustics because of its highly non-linear characteristics, high concentration of energy, and stable cavitation behavior. In this paper, bubble stability, the dynamic behavior of bubbles, non-invasive measurement of driving acoustic pressure and Mie scattering method are introduced.
