文摘The acoustic nonlinearity parameter B/A of a liquid containing microbubbles,sonicated dextrose albumin,has been measured by using second harmonic insert-substitution method.Results show that the value of nonlinearity parameter B/A for a bubbly liquid is significant and it obviously increases with increase of bubble number density.The high nonlinearity of the bubbly liquid is mainly dependent on the microbubble nonlinear oscillation.
