摘要:
高能炸药发生点火反应由3个主要的能量转移过程引起：摩擦或剪切热、自加热、冲击压缩。炸药发生反应的剧烈程度由缓慢燃烧到完全爆轰不等，而这主要取决于能量转移率、炸药的理化性能、壳体约束强度等变量。该文重点从撞击点火、热爆炸、弱冲击压缩和强冲击压缩（分为均质炸药和非均质炸药）等方面综述了国外近年来在高能炸药点火方面的研究进展，以炸药在撞击、热、冲击刺激下的试验方法和数学建模方法为主，同时介绍了最新的实验和仿真研究成果。
Abstract:
Ignition reactions of high explosives can be caused by three general energy transfer processes: impact ignition by frictional or shear heating, thermal heating and shock compression. The degree of violence of reaction varies from benign slow combustion to detonation of entire charge, that depends on many variables, including the rate of energy delivery, the physical and chemical properties of the explosive, and the strength of the confinement surrounding the explosive charge. This article focuses on foreign research progress of homogeneous and nonhomogeneous explosives in recent years in terms of impact ignition, thermal explosion, weak shock compression and strong shock compression. Meanwhile, the latest achievements on experimental and mathematical modeling regarding the ignition mechanism of explosives under the impact, thermal and shock stimulus are introduced.
