Abstract
Aseriesofsingle-shotdetonationexperimentswereperformedtounderstandthematching
characteristicsofwaveandflameinDDTforH2/airmixuresina60mmsquaretubethatwas2min

andwave,andhigh-speeddigitalimagingwasusedtotrackflamepropagationofDDTarea.The
matchingruleofshock-flamewasachievedbyanalyzingtheintensity、velocityandpositioncharacteristicsofwaveandflameindifferenttimealongthetube.
