摘要：

With a pressure supersonic interferometer especially devised for this purpose, nine organic liquids are examined at frequencies a little less than 200 kc and at temperatures varying from 22.7 degrees C to 25.5 degrees C for the various liquids. The acoustic velocity is measured at intervals from atmospheric pressure to a pressure of 300 kg/cm(2). The values of the acoustic velocity (in meters per second) in the liquids at the pressures indicated are given below: Liquid C2H5Br C Cl-4 CHCl3 C2H5OC2H5 C5H12 CS2 C6H6 C7H3 C6H5NH2 Atmospheric Pressure 885. 912. 986. 993. 1005. 1136. 1290. 1313. 1640. 300 kg/cm(2) Pressure 1000. 1048. 1097. 1255. 1281. 1268. 1416. 1447. 1745. This method is being used for the determination of the value of the specific heats at other than atmospheric pressure.
