摘要
分析了声吸收对变程干涉仪测量液体声速所带来的影响以及电量监测引起的测量误差．结果表明，声吸收在一定条件下是影响声速测量精度的重要因素之一．
The influence of ultrasonic attenuation and electrical circuits on the measurement of sound velocity with ultrasonic interferometer is analysed. It is shown that the ultrasonic attenuation is a main factor to be considered in accurate measurement of the velocity.
