| Abstract: | With the help of molecular thermodynamics, an expression is given of acoustical nonlinearity parameter B/A in terms of bulk compressibility in liquids, and the parameter is studied in hard sphere liquid described by Scaled Particle Theory. The results shown the expression is a concise and useful tool in stduying B/A from the view of molecular thermodynamics. |
