无论从材料的结构、性能，还是材料自身的成本和可加工性，有机聚合物二阶非线性光学材料都显示出了比无机晶体材料更加优越的应用前景。

Thirdly, Instead of using one-dimensional coupled map lattices model, we have constructed a combinable model, which is consisted of an one-dimensional chain, a two-dimensional netting grid and another one-dimensional chain as the drive-response system. So both the system's complexity for secret key streams and the efficiency for encryption have been increased.
