Effects of the Short-Range Structure on Second Harmonic Generation Relaxation Behavior in Nonlinear Optical Epoxy Polymers

设计合成了三种具有不同主链化学结构的二阶非线性光学功能化环氧聚合物，并对其化学结构进行了表征，考察了聚合物近程结构对材料极化后二次谐波产生弛豫特性的影响。

Three second-order nonlinear optical epoxy polymers with different main-chain structure were synthesized and characterized .

虽然两者均以非晶质相为主，并具有相似的近程结构模型，但在非晶质相中近邻八面体的连结方式和近邻四面体的连结有序性方面仍存在较大差异。

Although these two minerals are mainly composed of non crystalline phase and have the similar short range structure models , they still have the differences in the linkage form of adjacent octahedrals [ AlO 6 ] and in the linkage ordering of adjacent tetrahedrals [ MO 4 ] .

研究结果表明，液态水分子几何构型除与氢键的形成有关外，还与液体的近程有序结构有很大关系。

The study shows that besides the effects of H-bond , the geometry of water molecule in liquid is greatly influenced by the order structure of the liquid .
