摘　　要：通过简并四波混频法（ＤＦＷＭ）对“聚［３′－甲基－４′—二（Ｎ，Ｎ－氧亚乙基）胺基－４－硝基偶氮苯癸二酰］”薄膜的光致导构过程的研究，测得在上升和下降过程中，相位共轭光Ｉｐｃ随时间的变化规律并与理论结果相吻合．Photo-induced isomerization Process in Poly[3′-methyl-4′-bis(N,N-oxyethylene)amino-4-nitro azobenzene sebacoyl]film is studied by degenerate fourwave mixing.It is indicated that there are definite relations not only in the increase process of phase conjugate rays I pc but also in the decrease process of I pc ,and the relations are in accordence with theories in th paper.
