中文摘要：
从理论及实验上分析了介质温度对受激布里渊散射（stimulated Brillouin scattering,SBS）阈值及增益系数的影响.在理论分析的基础上,提出了一种通过测量SBS阈值来决定介质SBS增益系数的新方法.实验及测量结果表明,SBS增益系数会随着介质温度的增加而呈现指数上升的趋势.
英文摘要：
In this paper,the influences of medium temperature on threshold and gain coefficient of stimulated Brillouin scattering（SBS）in water are investigated theoretically and experimentally.Based on the theoretical analysis,a new method is proposed to determine the gain coefficient of SBS of the material by measuring the threshold.The experimental results indicate that the gain coefficient of SBS increases exponentially with the increase of medium temperature.
