Calculated diffusive equilibrium curve in the p a– R 0 plane (the positive slope indicates the stability) for an Ar bubble in 20 °C water with f = 34 kHz. The selected data near the curve for a relative gas concentration of c ∞/ c 0 = 0.004 are calculated to obtain the FWHM as a function of relative SBSL intensity. The unit 1 atm = 1.01325×105 Pa.
