摘　　要：从拉曼散射几率出发,推导出拉曼散射增益系数和散射截面的关系,并通过仿真模拟,调节参数,得出了增益系数和频移之间的关系曲线,并将其与实验曲线作比较,给出结果的定性分析。The relationship between Raman gain coefficient and Raman scattering section is deduced from Raman scattering probability. Based on the relationship, we get the curve of Raman gain coefficient and Raman frequency shift through numerical analysis and parameter adjustment, compare this curve with the curve of experiment, then the result in qualitative analysis is given.
