超声粘度测量的新方法研究

STUDY OF NEW METHOD OF MEASURING VISCOSITY BY ULTRASOUND

从理论上分析探讨了利用超声波在液体中的衰减与液体粘度的关系测量液体粘度的可能性,导出了粘性液体粘滞吸收衰减关系,并对蓖麻油进行了实验测定。研究结果表明,利用衰减法测量粘性液体的粘度是可行的。

This paper discussed the possibility of measuring the viscosity of viscous liquid by means of the relation bctween the liquid viscosity and the ultrasonic attenuation in theory, introduced the viscosity absorption equation for viscous liquid, and thus measured the viscosity of castor oil experimentally The research results showed that it is possible to measure the viscosity of viscous liquid by the ultrasoic attenuation method.
