Abstract

Ultrasonic longitudinal velocity and attenuation were measured for aqueous solutions of sorbitol at approximately 5 MHz. For pure sorbitol, the ultrasonic velocity reached 3200 m s(-1), consequently leading to a high acoustical impedance (around 5 x 10(6) Rayleigh) and good matching between the ultrasonic transducers and material samples.

摘要

在约5兆赫兹的频率下测量了山梨醇水溶液的超声纵向速度和衰减。对于纯山梨醇，超声速度达到3200米/秒，因此导致高声阻抗（约5×10⁶瑞利）以及超声换能器与材料样品之间的良好匹配。
