摘　　要：利用Ｕ（５）群链描述ＳｉＯ＿２分子振转谱的对称性质，并用群论方法计算光纤受激喇曼散射的跃迁矩阵元，给出它受激喇曼散射截面和增益系数，结果与实验进行了比较．The symmetry of rotation-vibration states of molecule SiO_2 is discribed by groupU(5).The matrix elements of stimulated Raman scattering are calculated by means of grouptheory approach in fiber. The cross sections and gain coefficients of stimulated Raman scat-tering are given. The results are agreement with the experimental values.
