中文摘要：

设计了一种用于液体运动粘度在线测量的声表面波传感器。利用液体对水平剪切模式声表面波（SH—SAW）传播性质的影响，推导得出液体的密度和动力粘度与SHSAW的传播速度变化的数学关系式，从而实现液体运动粘度的检测，设计了相应的实验设备。通过实验数据与理论数据的比较证实了该设计的可行性。

英文摘要：

An online-equipment for the measurement of liquid kinematic viscosity was designed in this paper. The paper revealed the effect of liquid on the spread properties of SH-SAW to get the mathematical relationships between density and dynamic viscosity of liquid and the change of SH-SAW propagation velocity, and to achieve the measurement of liquid kinematic viscosity. Then the laboratory equipment for the measurement of liquid dynamic viscosity was also designed. The comparison between the experimental data and theoretical data confirmed the feasibility of the design.
