摘　　要：从形成相应的理论算起,关于二相粒子与晶界之间相互作用的研究至今已有60多年的历史。主要从晶界方程和钉扎力模型两个方面阐述二相粒子/析出相钉扎晶界的模型研究进展,对比分析了每个物理模型的推导基础以及不足。文章最后对模型研究的发展做了展望。The modifications to the theory of interaction between grain boundary（GB） and the second-phase particle（SPP） have been made over the past six decades since the first analytical model for Zener pinning was proposed.The development of analytical model for interaction between GB and SPP was expatiated from two aspects.Furthermore,the physical rootstock and flaw of each model was also pointed out.Lastly,a possible prospect for the development of analytical model for GB pinned by SPP was presented.
