利用频率大于5 MHz的连续声波的机械共振，建立了一套同时测量薄圆盘样品中声速和衰减系数的自动测量系统。结果表明，在温度变化范围为60k /h ~ 3k /h的条件下，声速变化Δυs/ 0，可以在10-5的范围内以相对精度自动测量。
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 10-5 with changing temperatures at rates from 60 k/h to 3 k/h.
