摘要：
Using the mechanical resonance of continuous sound waves with frequency higher than 5 MHz, an automatic measurement system is set up for simultaneous measurements of sound velocity and attenuation coefficient in thin disk samples. It is confirmed that the change of sound velocity Δυs/υ0, can be measured automatically with relative accuracy within 10-5with changing temperatures at rates from 60 k/h to 3 k/h. © 1990 IOP Publishing Ltd.
