| 摘 要： | 本文从联立麦克斯韦方程和介质的声振动方程出发，在缓变振幅近似及小信号近似下得到耦合波振幅方程，以丙酮（Ｃ＿３Ｈ＿６Ｏ）为ＳＢＳ介质，利用计算机进行了受激布里渊散射相位共轭效应数值求解，得到ＳＢＳ阈值、饱和效应及二维情况下的ＳＢＳ相位共轭效应。理论计算表明，在小信号情况下受激布里渊散射具有良好的相位共轭效果。

NUMERICAL SOLUTION OF PHASE CONJUGATION IN SBS |

| Abstract: | In this paper，a numeracal solution was made from the Maxwell coupled wave equations and acoustic equations of pump laser and Stokes wave，under the condition of slowly envelope and small-signal approximations. The results which including SBS threhold， Stokes thanslation efficiency，gain satu- ration and SBS phase conjugation in the meterial of C_3H_6O were obtained。They showed that the best phase conjugation phenomena presentation when the pump laser was just higher than the SBS threshold. |
