In chapter 2 , we study the existence of the global attractor the complex ginzburg - landau equation in three dimensions space . first , we consider existence of local solu - tion . for a given perturbation n ( u ) , we prove n ( u ) is contractive and locally lipschitz continuous 在第二章，考虑ginzburg - landau方程在三维空间的整体吸引子的存在性，首先考虑ginzburg - landau方程的局部解的存在性，对于一给定的扰动项n ( u ) ，证明n ( u )是收缩的且是局部lipschitz连续的。
In the framework of the transverse ising model ( tim ) , landau phase transition theory and the electrostatic field theory , we study the physical properties of the ferroelectric thin film , bilayer , sandwich structure , multilayer with a non - polarization slab and a two - dimension polar lattice model with polar defects . the main work and results are as follows : first , the long - range interaction in ferroelectric material is sometimes neglected in the previous studies . we introduce the long - range interaction in the framework of the tim and the landau theory 本文在横场伊辛模型、朗道相变理论以及静电场等理论的框架内，对铁电薄膜、铁电双层膜、铁电三明治结构以及含有杂质层的铁电多层膜和含有偶极缺陷的二维偶极点阵系统等多层铁电系统的相变、热电、介电、电滞行为等物理性质进行了深入研究。
