This work presents the review and classification of the scenarios of the development of the final stage of flame acceleration in channels and tubes including the transition to detonation on the flame front and formation of the conditions for kernel ignition ahead of the front. An approach to the numerical assessment of the detonability of combustible gaseous mixtures is formulated based on the classification of high-speed combustion modes proposed by the authors, and the general possibility of the practical application of such an approach is shown. The quantitative estimates of the critical conditions for the stable detonation formation as a result of flame acceleration and upon the transmission of the detonation wave, which are in agreement with the available published experimental data, are presented.

通道内快速燃烧波发展和爆燃-爆轰过渡的情景分类

这项工作对通道和管子中火焰加速的最后阶段发展的情景进行了回顾和分类，包括在火焰前沿过渡到爆炸以及在前沿提前形成核点燃的条件。基于作者提出的高速燃烧模式的分类，提出了一种可燃气体混合物爆炸性数值评估的方法，并显示了这种方法实际应用的一般可能性。给出了由于火焰加速和爆炸波的传播而稳定起爆形成的临界条件的定量估计，这些估计与可用的公开实验数据一致。
