The asymmetry in the effects of variations of X/Cp and pD 2 large jS arises through the influence on the reactant concentration in the reaction zone. A symmetric behavior could be anticipated if the reaction extended throughout the entire thickness of the deflagration. 

The type of reasoning that has been given here can be extended to take into account reaction orders different from uni y and multiple-reactant, one-step chemistry. For a one-reactant proce of reaction order n, w is proportional to the reactant concentration (in the reaction zone) to the nth 

There have been a number of analyses employing activation-energy asymptotics for two-reactant, one-step chemistry. Most of these have been summarized by Mitani [40] reviews also may be found elsewhere [10], [13].

With notable exceptions [41], the formulations have been based not on equation (8) but instead on diffusion equations of the type
