摘　　要：在新型低温燃烧模式中,大多存在自燃着火和火焰传播共存的现象,但二者之间的相互作用机制尚且不明.鉴于此,从实验和数值模拟两方面回顾了国内外关于自燃和火焰传播的判别方法,总结了各种方法的特点及适用范围,并对数值模拟中的速度判定、Da数判定和CEMA判定3种方法进行了重点介绍.在未来,将机器学习和图像处理技术应用于燃烧诊断领域,有望实现自燃着火和火焰传播的定量和定性判断,明晰两者之间的作用机制,为新型燃烧模式中燃烧过程的调控提供理论指导.Spontaneous ignition and deflagration coexist in most of novel low-temperature combustion modes,but the interaction mechanism between the two remains unclear.In light of this,a comprehensive review of identi-fication methods for spontaneous ignition and deflagration is conducted from both experimental and numerical simulation perspectives,covering both domestic and international research.Various approaches are summarized in terms of their characteristics and applicability,with particular emphasis placed on three key methods:velocitybased method,Damköhler number-based method,and CEMA(chemical explosive mode analysis)method,thereby providing a theoretical foundation for regulating combustion reaction rates in engines.In the future,the application of machine learning and image processing techniques in the field of combustion diagnostics is expected to realize the quantitative and qualitative assessment of spontaneous ignition and deflagration,and elucidate the interaction mechanisms between the two,which aims to provide theoretical guidance for regulating the combustion process in novel combustion modes.
