摘要：

The speed of sound in mercury, c, for frequencies between 9. 5 and 10. 5 MHz, has been measured by comparison with a frequency-stabilized infrared laser. For 75 mm diameter mercury columns with lengths L from 50 to 400 mm, temperatures T between 21. 5 and 29. 2 degree C, and pressures P up to 230 kPa, the results are given. These results have not been corrected for diffraction effects and the length L does not include that of a 10 mm beryllium buffer disk between the mercury and the ultrasonic transducer. The indicated length dependence is expected to decrease as the length increases beyond 400 mm.
