摘　　要：对斜爆震波起爆特性及其波系结构的研究进展进行综合评述,分析其研究现状与存在的不足,总结了斜爆震波起爆和驻定特性研究进展,重点回顾了斜爆震波起爆准则和驻定条件,对斜爆震波的诱导区结构和波面胞格结构研究进行了总结,对斜劈构型对斜爆震波的影响研究现状进行了概述。综述表明,斜爆震波的起爆、驻定和波系结构还需持续开展研究,特别需要关注的是平面斜爆震波的起爆准则和驻定条件,在真实流动条件下更深入研究斜爆震波宏观结构和波面结构的形成机理,探索受限空间内斜爆震波起爆、反射和驻定特性。A review of the research progress on oblique detonation waves is conducted and some challenges of current studies are analyzed,providing a guidance for the future investigations on oblique detonation waves.Firstly,research progress on the initiation and stability characteristics of oblique detonation waves are summarized,especially on initiation criterion and stability condition.Then investigations on the transition structure and cellular structure of oblique detonation waves are provided.Besides,effects of geometrical structure on oblique detonation waves are introduced.The review shows that continuous researches on the initiation and stability characteristics as well as structure of oblique detonation waves are needed.The future researches may focus on the initiation criterion and stability condition of wedge-induced oblique detonation wave.The formation mechanism of transition structure and cellular structure in the real flow condition are needed to be deeply investigated.Moreover,it is necessary to further explore the initiation,reflection and stability characteristics of oblique detonation waves induced by a confined wedge.
