摘　　要：对大量位错滑移模型及其实现过程进行分析的基础上,结合各种位错滑移模型的特点,描述了各模型力学参量的微观机理,总结了一些具有代表性的位错滑移模型及其实现过程,为后续的位错滑移理论模型的研究提供参考。Dislocation slip model is the elastic plastic stress field calculation of foundation, because the traditional theory of dislocations are difficult determined by the boundary conditions, dislocation core size uncertainty and many deficiencies, it leads to the existence of a variety of dislocation slip model coexist,model implementation method various pattern, makes the study of dislocation micro mechanism lack of complete and unified theory. Based on a great deal of dislocation slip model and its implementation process based on the analysis, combined with a variety of dislocation slip model characteristics, This paper describes the model of mechanics parameters of microscopic mechanism, summarizes some typical dislocation slip model and its realization process, provide the reference. for the research of the follow-up dislocation slip theory model
