Abstract	This article shows that, unlike the situation in many other combustion problems, the progress towards detonation behind an initiating shock wave when the chemistry is modeled using a radical chain-branching mechanism is fundamentally different from the progress found when a global one-step model is used. In the latter case, a uniformly supersonic (shockless) wave of chemical activity is found to emerge at the end of an induction process. Only after this "induction flame " slows down significantly is it possible for a genuine propagation mechanism to create a Zeldovich-von Neumann-DSring detonation structure. When dominated by chain branching, the reaction wave produced by the induction process is subsonic, and can therefore be influenced by propagating thermodynamic disturbances (as originally pointed out by Strehlow). The resulting chemical-hydrodynamic interaction causes an acceleration of the wave prior to the emergence of the detonation. It is suggested that the existence of these two distinct forms of initiation may provide a means of testing for the relative importance of possible chain-branching and state-sensitive mechanisms in the initiation of detonations, especially where little kinetic data are yet available (as, for example, in condensed explosives).
