It`s a form of the general governing equation for a material undergoing one or more reactions. Its from the FDS Users Guide, within the section Solid Fuels that do NOT Burn at a Specified Rate, under the sub-heading The Reaction Rates. The version shown in the dialog does the substitution to combine some terms and includes the threshold temperature discussed in Special Topic: The "Threshold Temperature".

As for what it means, I`m not sure. Our hope was that by including it we could help FPEs understand how the dialog inputs apply to the simulation model.
