英文摘要：

Orientation image microscopy is a new kind of method of analyzing the microstructure of relevant materials. In this paper, the fundamental principle, resolution, sample preparation and data treatment of orientation image microscopy are generally investigated. Besides, combined with what we have achieved in our research project, the application of orientation image microscopy to the microstructure, texture, crystal rotation and dislocation boundaries of single crystal copper wires with and without plastic deformation is also briefly analyzed.
