%X 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%.
