主　　题：ultrasonic velocity (U) amino acid salt effect isentropic compressibility organic salt 

摘      要：The ultrasonic velocity （U）, has been measured for three a-amino acids, namely L-lysine monohydrochloride, L-arginine and L-histidine in solutions （1 mol/L aqueous） of sodium acetate （SA）, potassium acetate （PA） and calcium acetate （CA） at different temperatures （303.15, 308.15, 313.15, 318.15 and 323.15 K）. With the help of these results various ultrasonic derived parameters, viz. isentropic compressibility （Ks）, change in isentropic compressibility （△K5）, relative change in isentropic compressibility （△Kr）, specific acoustic impedance （Z）, relative association （RA）, and apparent molal compressibility （Фks） have been estimated. The results have been interpreted in the light of intermolecular interactions between solute and solvent.
