摘要
利用SV—DH声速测试仪测量超声波在不同液体介质中传播纵波的传播速度,进一步测量出这些液体压缩系数。测量结果与标准值相比,利用该方法测量液体压缩系数具有原理简单、相对误差较小的特点。为测定液体的压缩系数提供了一种新方法。
Using SV--DH Ultrasonic Velocity Testers liquid medium in different propagation velocity of longi-tudinal wave propagation, Further measuring the liquid compressibility, principle is simple, method is reliable com-pared with the standard value measurement. The relative error is small. The method is feasible and value. A kind of new measuring method of liquid compressibility is obtained.
