摘要：

The measurement of ultrasonic velocity and sound attenuation, and density has been carried out for several liquid Bi-Ga alloys from the melting points to about 800-degrees-C. The ultrasonic velocity and its attenuation were determined by means of an ultrasonic pulse transmission method and the density was determined by a gamma-ray absorption method. The adiabatic compressibility and molar volume of this system are obtained by the observed sound velocity and density. The temperature coefficient of the adiabatic compressibility is rather small in the concentration above the miscibility gap region than in the other concentration. The thermodynamic properties of this system are discussed based on the correlation between the structure and the compressibility.
