这里，R是气体常数；E为活化能；K是指前因子；cR、cI、ρR、ρI、λR、λI分别为比热系数、密度、导热系数。我们使用以下无因次参数：燃烧波中反应区和受热区厚度之比，γ= R cR/EQ；反应速率的温度依赖性因子，β= RT * /E；可燃层与惰性层单位体积比热的比值，σ ρ=(cIρI)/(cRρR)；可燃层与惰性层导热系数之比σλ= λI/λR。
Here, R is the gas constant; E is the activation energy; k is the pre-exponential factor; and cR, cI, ρR, ρI, λR, and λI are the specific heats, densities, and heat conductivity coefficients, respectively. We use the following dimensionless parameters: the ratio of the thicknesses of the reaction and heating zones in the combustion wave, γ= R cR/EQ; the factor in the temperature dependence of the reaction rate, β= RT∗/E; the ratio of the specific heats (per unit volume) of the combustible and inert layers, σcρ=(cIρI)/(cRρR); and the ratio of the heat conductivity coefficients of the combustible and inert layers, σλ= λI/λR.
