| 摘 要： | 本文提出了一种利用受激布里渊散射(SBS)能量反射率的变化测定不同温度时的液体介质运动黏度的方法.液体介质的运动黏度随温度而变化,这导致了介质增益系数和SBS能量反射率的变化,因此通过SBS能量反射率的变化可测定不同温度时的液体介质的运动黏度.在Countinuum Nd: YAG种子注入激光系统中测定了不同温度时的水的运动黏度并与运动黏度计测定的结果进行了比较.用本方法获得的不同温度时的水的运动黏度测量值与运动黏度计测量值很接近,相对误差小于5%.

| Abstract: | In the paper, a method of measuring the kinematic visicosity of liquid medium based on stimulated Brillouin scattering (SBS) at different temperatures is proposed. The kinematic visicosity of liquid medium, which is related to the temperature, greatly affects the gain coefficient of medium and SBS characteristics. Therefore the kinematic visicosity at different temperatures can be measued by the reflectivity of SBS. In experiment, the kinematic visicosities of water at different temperatures are determined based on SBS in continuum's Nd:YAG seed-injected laser and compared with the results measured from kinematic viscosimeter, and the relative error of the experiment results is less than 5%. |
