摘　　要：本文通过电子显微技术与晶体学的对称群理论结合,对金属氧化物的畴结构进行静态及动态表征。主要包括:(1)利用电子衍射与球差校正透射电子显微技术,对畴结构的取向关系、原子尺度界面构型进行分析;(2)基于原位透射电子显微技术实时观察畴结构的生长,并研究其微观力学和电学行为。文章结果为金属氧化物构效关系的搭建及应用设计提供借鉴。Combining both the electron microscopy with crystallographic group theory, this paper reports our recent progress regarding the dynamic and static characterizations of domain structures in different metal oxides：（1） investigating the orientation relationships of domain structures and atomic-scale configurations of the various interfaces by applying electron diffraction and aberration-corrected transmission electron microscopy;（2） revealing the growth dynamics of domain structures as well as exploring their microscopic mechaniccal and electrical behaviors based on in situ transmission electron microscopy. These results provide the guidance for constructing the structure-property relationships and contribute to the property-directing structural design in metal oxides.
