摘　　要：综述了固体非均质炸药冲击点火与起爆模型研究的进展,主要探讨基于经验数据模型、微观机制模型和分子动力学理论模型这3类模型的理论基础、存在的问题和工程应用前景,认为基于微观机制点火与起爆模型具有物理概念清晰以及能够预测实验结果的优点和较好的工程应用前景,提出了后续发展的建议。This review aims at the main progresses of the models describing shock-induced ignition and detonation of solid heterogeneous explosives since 1980s.These models can be divided into three types： empirical models,micromechanical models and molecular dynamics based models.The corresponding theories to these models are analyzed as well as the existent difficulties in theoretical investigation and practical application,and the application possibilities of these models to complex engineering problems are explored.Investigated results show that the micromechanical models take on unambiguous concepts and can predict the experimental results,and they have good application prospects in engineering practice.At last,some advices about the micromechanical models are given.
