摘　　要：为了设计新的具有较高非线性极化率和光损耗小的有机非线性光学（ＮＬＯ）材料，需要了解不同的有机结构对分子非线性的影响。在此基础之上，建议用平行对比的方法来近似估算取代二苯多烯和聚二乙炔（ＰＤＡ）的三阶非线性光学极化率。In order to design new organic NLO materials with both higher nonlinear optical susceptibility andreasonable optical loss characteristics it is necessary to understand how different organic structural elementsaffect the nonlinearitv of materials at the molecular level. On the basis of the new understanding,it issuggested that X￣(3) value of PDA can be appoximately esti mated by use of comparative method.
